Guides - Scottish Power Electricity Rates 2026: Unit Rates, Tariffs, Standing Charges & Honest Review

Quick Verdict: 3.8 / 5 Scottish Power is a genuinely green supplier with the UK’s most complete EV charging package, but it sits in the bottom half of the market on customer service. Best for EV owners, eco-conscious households, and anyone who wants the stability of a large, well-backed supplier. Less ideal if your top priority is the lowest possible unit rate or hassle-free customer support.

The Honest Starting Point

If your Scottish Power bill has left you quietly wondering whether you’re paying more than you should, you’re in good company.

Millions of UK households are still on standard variable tariffs, often without realising that a cheaper fixed deal or a smarter tariff could trim their annual costs. When wholesale energy prices surged in late 2021, suppliers pulled fixed deals off the market almost overnight, and a lot of customers simply stayed on variable rates because there was nothing obvious to switch to. Many still are.

Here’s where things stand right now: from 1 April 2026, the Ofgem price cap dropped by 7%, bringing the typical dual-fuel household bill down to £1,641 per year, the lowest cap level in several years. Scottish Power has confirmed its standard variable customers will see their annual bill fall from £1,758 to £1,641, a saving of £117.

But the cap doesn’t guarantee you’re on the best deal available. A lot of people miss this. The price cap doesn’t set a hard limit on your unit rate or standing charge individually. It limits what a typical household pays overall, which means your supplier could charge a higher unit rate but offset it with a lower standing charge, or the other way around.

This guide works through Scottish Power’s current electricity unit rates, standing charges, a full tariff comparison, honest pros and cons, and a clear verdict, all updated for April 2026, so you can make a confident decision about whether to stay, fix, or switch.

What Scottish Power Electricity Rates Actually Consist Of

Every Scottish Power electricity bill breaks down into two separate charges. The unit rate is what you pay per kilowatt hour (kWh) of electricity you actually use. Use more, pay more. The standing charge is a fixed daily fee you pay regardless of usage, covering the cost of keeping your home connected to the grid.

Your tariff type, whether standard variable, fixed-rate, Economy 7, or EV, determines what unit rate you pay and whether that rate can change while you’re on it.

Scottish Power Electricity Unit Rates 2026

These are Scottish Power’s current domestic electricity rates, effective from 1 April 2026.

All rates reflect the April to June 2026 Ofgem price cap period and apply to domestic customers paying by monthly Direct Debit. The figures below are national averages across England, Scotland and Wales. Your exact rate will differ by region. Check your Tariff Information Label at  scottishpower.co.uk/tariff-information-labels  for postcode-specific figures.

Standard Variable Tariff (SVT), April 2026:

• Unit rate: 24.67p per kWh
• Daily standing charge: 57.21p per day
• Typical annual electricity bill: approx. £875 (electricity only, based on 2,700 kWh/year)
• Typical annual dual-fuel bill: £1,641

Economy 7 Tariff, April 2026 (Regional Averages):

Economy 7 day and night rates are regional averages under the April 2026 cap structure. Your rates will vary. Check your bill or get a postcode quote at scottishpower.co.uk.

Quick answer if you’re searching: Scottish Power’s electricity unit rate from 1 April 2026 is 24.67p per kWh on the standard variable tariff, with a daily standing charge of 57.21p. A typical household using 2,700 kWh per year pays approximately £875 per year for electricity alone.

Scottish Power Tariff Comparison: All Current Options Side by Side

A few things worth flagging here.

Every Scottish Power tariff, including the basic Standard Variable, supplies 100% renewable electricity. That is a genuine differentiator. British Gas, for comparison, only includes green electricity on selected tariffs, not all of them.

The Cap Tracker is easily the most overlooked option on this list. It sits fractionally below the price cap every quarter, carries no exit fee, and requires no long-term commitment. If you’re currently on the SVT with no specific reason to fix, switching to the Cap Tracker is a straightforward, free improvement. There is no reason not to.

The Green Fixed May 2027 tariff bundles 12 months of boiler insurance into the deal, worth approximately £54 per year. For households that need boiler cover anyway, that can effectively offset the £50 per fuel exit fee if you ever need to leave early.

Is Scottish Power Cheaper Than the Ofgem Price Cap?

This is what most people are actually asking when they search for Scottish Power’s rates, so here’s the direct answer.

Scottish Power’s standard variable tariff tracks the Ofgem cap exactly. It does not consistently undercut it. When Ofgem moves the cap, Scottish Power’s SVT rates move with it. British Gas and EDF operate the same way, which is why SVT rates across all three are near-identical in any given quarter. There’s no pricing magic happening on the default tariff.

The exception is the Cap Tracker, which sits approximately £7.50 per fuel per year below the standard variable rate. Modest, but real, and there’s no catch.

Fixed tariffs can land cheaper or more expensive than the cap depending on when you lock in and what the cap does next. With the July 2026 cap forecast to rise due to wholesale market volatility, fixing at April 2026 rates could offer meaningful protection. But it cuts both ways if prices fall.

How the price cap has moved recently:

The takeaway worth keeping in mind: even with the April 2026 reduction, electricity unit prices are about 13% higher than mid-2024, and bills remain roughly 35% above pre-crisis levels. Being on the SVT means your rate shifts with every quarterly cap change, up or down.

Scottish Power Standing Charges: What You’re Actually Paying Before a Single Unit

The standing charge is one of the most misunderstood lines on any energy bill, and for low-usage households, it can easily be the biggest cost driver.

A standing charge is a fixed daily amount added to your bill regardless of how much energy you use, even if the property is empty. It covers network maintenance, metering, and certain government levies spread across all customers.

From April 2026, the Ofgem cap sets the average electricity standing charge at 57.21p per day, which adds up to £208.82 per year before you’ve used a single unit. That figure actually increased from 54.75p in Q1 2026, even as the overall cap fell. Worth noting.

Regional variation is real. Standing charges differ based on where you live because maintaining the distribution network costs different amounts across different regions. The gap between the cheapest and most expensive regions can run to 10 to 15p per day, so a customer in South West England may be on a meaningfully different daily rate than one in North Scotland.

For low-usage households, this matters more than most people realise. A single person in a small flat using 1,000 kWh per year may find the standing charge represents over 40% of their total electricity bill. In that situation, a tariff with a lower daily standing charge, even at a slightly higher unit rate, could actually produce a lower annual total.

Practical tip: check your last three months of bills and calculate your average monthly kWh. If you’re using under 150 kWh per month, prioritise comparing standing charges rather than just unit rates when looking at deals.

Real Monthly Bill Examples at April 2026 Rates

No two households pay the same bill. Here is what Scottish Power’s April 2026 SVT rates look like in practice across different household sizes.

Formula used: Monthly cost = (monthly kWh x 24.67p) + (30 days x 57.21p)

Based on Ofgem’s April 2026 SVT cap rates for Direct Debit customers, electricity only. Gas bills are separate.

Two things stand out from these numbers. Even the smallest household pays £17.16 per month in standing charges before consuming anything, which is nearly a third of the total electricity bill for a low-energy user. And the gap between a small flat and a large family home is around £87 per month on electricity alone.

Scottish Power Power Saver: Half-Price Electricity Explained

This is a feature that most competitors don’t mention, and for the right household it’s genuinely one of the more useful things Scottish Power currently offers.

Power Saver is Scottish Power’s time-of-use tariff that gives customers half-price electricity at selected times throughout the week. Unlike a fixed overnight Economy 7 window, Scottish Power announces the discount windows in advance, and you receive the saving as a bill credit.

Who benefits most? Households with flexible daily routines who can shift heavy electricity use, dishwashers, washing machines, tumble dryers, EV charging, into the discount windows. A household that actively uses Power Saver slots for three to four appliance cycles per week could realistically cut their annual electricity costs by £80 to £120 compared to standard SVT rates.

You need a compatible smart meter sending half-hourly data to Scottish Power and a monthly Direct Debit. Customers without a smart meter aren’t eligible, but installation through Scottish Power is free. To sign up, log into your online account, navigate to tariff options, and select Power Saver. The switch is free and typically takes effect within 5 working days.

What “100% Green” Actually Means With Scottish Power

Scottish Power’s renewable credentials are genuinely its strongest selling point, but “100% green electricity” means different things from different suppliers, and it’s worth understanding what you’re actually getting.

When Scottish Power says all its tariffs include 100% renewable electricity, it means the electricity you consume is matched unit for unit to generation from Scottish Power’s own UK wind farm portfolio. The company owns and operates over 1,157 wind turbines across approximately 38 onshore sites, making it the UK’s largest generator of onshore wind power.

The mechanism that proves this is Renewable Energy Guarantee of Origin (REGO) certificates. Some suppliers buy REGO certificates on the open market from generators in other countries, so your “green tariff” might technically be matched to Norwegian hydro power rather than anything happening in the UK. Scottish Power’s tariffs are backed by electricity from its own UK turbines, which is a more direct connection than buying certificates from overseas generators. For more on how REGOs work, the  Ofgem website explains the framework clearly.

Scottish Power was the first of the Big Six suppliers to generate exclusively from renewables, having sold its gas generation assets and closed all coal-fired power stations before several competitors made similar claims. That history matters if you’re comparing green credentials seriously.

The honest caveat: the UK electricity grid is shared. The actual electrons entering your home come from a mix of sources regardless of your tariff. What “100% green” guarantees is that the equivalent amount of renewable energy has been added to the grid on your behalf. This is the industry-standard model and it isn’t unique to Scottish Power, but the direct UK wind farm backing does put it a step ahead of suppliers relying purely on bought-in certificates.

Scottish Power Customer Reviews: The Full Picture for 2026

Most comparison sites either skip customer service entirely or just quote a headline Trustpilot score. Here is a more complete view.

Headline scores:

• Trustpilot: 4.3 out of 5 (over 150,000 reviews), rated “Excellent”
• Citizens Advice supplier rating: Top of the large suppliers overall
• Which? 2025 customer score: Below 60%, two out of five stars across service ratings

The split in customer experience is consistent across review platforms. Customers who set up their account, receive accurate bills, and never need to contact Scottish Power directly tend to report neutral to positive experiences. Customers who need to dispute a bill, resolve a meter reading issue, or chase a complaint tend to report significantly more frustrating experiences, particularly around response times and the number of contacts required to reach resolution.

Where customers praise Scottish Power:

• Online account management and the app for smart meter customers
• A straightforward switching process, typically 5 working days
• Clear communication about tariff changes before they take effect
• The Cancer Research UK partnership, which has raised over £40 million since 2012

Where complaints cluster:

• Billing errors on estimated reads, particularly for customers without smart meters
• Wait times on the phone
• Difficulty resolving complex account issues like dual fuel switches and final bill disputes

The honest verdict: Scottish Power, British Gas, and EDF Energy all scored below 60% in Which?’s 2025 supplier assessment. Scottish Power isn’t uniquely poor. It’s representative of a wider pattern across large legacy suppliers. But the gap versus newer entrants is real and consistently measured. Octopus Energy has been a Which? recommended provider for nine consecutive years.

Scottish Power vs Other UK Suppliers

Scottish Power vs British Gas

On standard variable tariffs, the two are near-identical in price. Both track the Ofgem cap. The meaningful differences come down to green credentials (Scottish Power covers all tariffs versus selected-only at British Gas) and the EV charging package. British Gas has a broader range of home services and boiler cover products, which matters to households wanting one provider for energy and home care.

Scottish Power vs Octopus Energy

This is the sharpest comparison in the market, and on most measures Scottish Power doesn’t consistently come out ahead. Octopus regularly prices fixed tariffs below the Ofgem cap. Its Intelligent Octopus EV tariff offers an overnight rate of approximately 7p/kWh versus Scottish Power’s EV Saver at 8.5 to 9.5p/kWh. Its customer satisfaction scores are substantially higher by every independent measure. For households where the Cancer Research UK partnership or direct UK-wind-backed generation genuinely matters, Scottish Power has a real argument. On price and service alone, the advantage sits with Octopus. According to Which?’s energy supplier ratings, the gap between the two on customer experience has been consistent across multiple years.

Scottish Power Pros and Cons

Pros:

Genuine renewable credentials. Scottish Power was the first Big Six supplier to generate 100% renewable electricity. Every tariff, including the basic SVT, comes with electricity matched to its own UK wind farms, not certificates bought on the open market. For households where the source of green energy matters, this is the most direct offer from any large UK supplier.

Low collapse risk. As a subsidiary of Iberdrola, one of the world’s largest utility groups serving over 100 million customers globally, Scottish Power carries very low financial collapse risk. For customers who remember the wave of smaller supplier failures in 2021 to 2022, this matters.

Comprehensive EV package. Scottish Power is the only major UK supplier offering home EV charger installation, a dedicated EV time-of-use tariff, and smart charging optimisation under one roof. For EV owners, that convenience is hard to replicate.

Broader tariff range than most competitors. From the no-frills Cap Tracker to green fixed deals with bundled boiler insurance, Power Saver half-price slots, and EV-specific products, Scottish Power covers more household types than most large suppliers do.

Cancer Research UK partnership. Over £40 million raised since 2012. For customers who factor charitable impact into their purchasing decisions, this is a unique differentiator.

Cons:

Customer service below market average. Scottish Power scored below 60% in Which?’s 2025 assessment. Customers who need to resolve billing disputes or contact the company repeatedly report long wait times and multiple contacts needed to reach resolution. This isn’t unique to Scottish Power among large legacy suppliers, but it’s a real limitation compared to newer entrants.

The SVT offers no pricing advantage. If you’re on the Standard Variable Tariff without actively choosing it, you’re paying the same rate as British Gas or EDF. There’s no loyalty benefit to staying on the default deal.

£50 per fuel exit fee on fixed tariffs. Locking into a fixed deal costs £100 total to exit early for a dual-fuel customer. Octopus charges no exit fees on fixed tariffs, giving it more flexibility for customers whose circumstances change.

EV overnight rate isn’t the market’s cheapest. At 8.5 to 9.5p/kWh, the EV Saver is competitive but not the best available. Octopus Intelligent Go offers approximately 7p/kWh overnight, which adds up for high-mileage drivers.

Who Should Choose Scottish Power?

Scottish Power works well if you own or plan to own an EV and want a complete charging package from one provider, if direct UK-wind-backed renewable electricity genuinely matters to you, if you’re a larger household that can take advantage of Power Saver discount windows, or if you want the financial stability of an Iberdrola-backed supplier with negligible collapse risk.

Who should look elsewhere?

If your top priority is the lowest possible unit rate, the market may have better-priced fixed deals for your postcode right now. If seamless customer service is non-negotiable, Octopus consistently outperforms Scottish Power across every independent measure. And if you want the cheapest available EV overnight rate, Octopus Intelligent Go currently wins on price.

How to Get Cheaper Scottish Power Deals

Switch to the Cap Tracker. The fastest way to cut your bill without switching supplier is to move off the SVT. The Cap Tracker sits approximately £7.50 cheaper per fuel per year than the Standard Variable tariff, has no exit fees, and takes minutes to arrange. For most SVT customers, there’s genuinely no reason to stay on the default deal.

Use Power Saver. If you have a smart meter and can shift heavy weekend electricity use, dishwasher, washing machine, EV charge, into the Power Saver discount windows (every Saturday and Sunday between 11am and 4pm), the savings accumulate meaningfully over a year without needing to change your tariff.

Consider fixing before July 2026. The July 2026 cap is forecast to rise due to wholesale market volatility. Early estimates suggest it could add around £24 per month to bills. Locking into a fixed tariff at April 2026 rates, whether with Scottish Power or another supplier, could offer real protection. Factor in the £50 per fuel exit fee before committing.

Get a smart meter if you don’t have one. Scottish Power installs them free of charge. It’s the gateway to Power Saver, the EV Saver tariff, and EV Optimise, three products that can each deliver meaningful savings that aren’t accessible on standard metering.

Pay by monthly Direct Debit. Switching to monthly Direct Debit places you on the lower price cap tier immediately, saving approximately £131 per year versus cash or cheque payment on a typical dual-fuel bill.

Run a full market comparison. Scottish Power’s deals aren’t always the best in your postcode. Running a comparison through Ofgem-accredited sites like MoneySavingExpert, MoneySuperMarket, or Uswitch takes under five minutes and shows live fixed deals across the whole market. If your switch is delayed beyond the agreed date, you may be entitled to £40 compensation under Ofgem switching rules.

How to Switch to Scottish Power

Switching to Scottish Power, or away from it, is straightforward. Your electricity supply is never interrupted during the process.

Step 1: Get a quote. Visit scottishpower.co.uk or use a comparison site. Enter your postcode and current usage (from a recent bill) to see available tariffs and estimated annual costs.

Step 2: Compare tariffs carefully. Look beyond the headline annual figure. Check the unit rate, daily standing charge, contract length, and whether an exit fee applies. Your actual monthly usage pattern matters more than the Ofgem “typical household” benchmark of 2,700 kWh/year.

Step 3: Apply online. Takes around five minutes. You’ll need your address, current supplier name, meter reference number (MPAN, found on your current bill), and bank details if setting up Direct Debit.

Step 4: Your new supplier handles the rest. Scottish Power contacts your existing supplier and manages the switch. You have 14 days to change your mind after signing up.

Step 5: Submit your final meter reading. Take a reading on your switch date and submit it to both suppliers so your final bill from the old supplier is accurate.

Step 6: Final bill and credit refund. If your old supplier owes you a credit balance, they must refund within 10 working days of issuing your final bill. Miss that deadline and you may be entitled to automatic compensation.

How to Complain to Scottish Power (And Escalate If Needed)

This section is missing from most competitor guides, but it’s often the information people need most before choosing a supplier.

Step 1: Contact Scottish Power directly. Use online webchat (available via your account), call the residential customer service line, or write to their Glasgow head office. Contact details are listed under “Contact Us” on scottishpower.co.uk.

Step 2: Request a formal complaint reference. Ask Scottish Power to log your issue as a formal complaint. This starts the official clock. Suppliers are required by Ofgem to resolve complaints within eight weeks.

Step 3: Escalate to the Energy Ombudsman if unresolved. After eight weeks, or if Scottish Power issues a “deadlock letter,” you can escalate to the Energy Ombudsman for free. The Ombudsman can award up to £400 in compensation and require Scottish Power to take specific actions.

Step 4: Contact Citizens Advice for independent guidance. While Ofgem doesn’t handle individual complaints directly, Citizens Advice offers a free energy consumer helpline on 0808 223 1133 for anyone who needs independent support.

Scottish Power Business Electricity Rates

Business energy pricing works differently from domestic tariffs. For most business customers, a custom quote is required.

Scottish Power offers gas and electricity for businesses of all sizes, with all tariffs backed by 100% renewable electricity. Three core structures are available.

Fixed for Business locks in your unit rate for 1, 2, or 3 years, providing budget certainty regardless of wholesale price movements. Online account management and energy efficiency guidance via the Carbon Trust are included.

Renewable for Business delivers 100% renewable electricity at fixed rates for up to 3 years, backed by REGO certificates from Scottish Power’s own generation portfolio.

Standard Variable carries no fixed contract and no exit fees. Rates move with the market, which suits businesses that want flexibility and plan to benchmark regularly.

As a reference point, Scottish Power’s business electricity unit rates for a London-based business consuming 25,000 kWh per year were in the mid-20s pence per kWh range on standard variable in early 2026. Negotiated fixed-rate deals for higher-consumption businesses typically come in below that level.

Business electricity rates are not subject to the domestic Ofgem price cap. They’re negotiated based on your consumption level, location, meter type, and contract length. The right time to engage a broker or run a comparison is 5 to 6 months before your current contract expires.

Scottish Power also offers EV fleet charging infrastructure, covering fast, rapid, and ultra-fast charge point installation with no upfront costs, alongside a 100% green electricity supply tariff.

Scottish Power EV Tariff: Is It Worth It?

For the right customer, the EV Saver is Scottish Power’s best-value product and one of the most detailed EV energy packages available from any UK supplier.

The EV Saver Tariff provides a cheaper off-peak rate for charging your electric vehicle at home between midnight and 5am, with electricity matched 100% to Scottish Power’s own renewable generation.

• Off-peak night rate: approximately 8.5 to 9.5p per kWh
• Standard daytime rate: 24.67p/kWh (same as the SVT)
• Smart meter required: yes, with half-hourly data
• Payment: monthly Direct Debit
• Exit fee: none, it’s a variable tariff
• EV charger brand: any, you’re not locked into a Scottish Power charger

The maths in practice: Charging a typical 60kWh EV battery at the standard SVT rate of 24.67p costs around £14.80 per full charge. At the EV Saver overnight rate of 8.5p, that same charge costs approximately £5.10, a saving of nearly £10 per charge. For a household covering 700 miles per month, that adds up to over £100 in annual savings on charging alone.

EV Optimise add-on: Rather than restricting cheap charging to a fixed overnight window, EV Optimise uses smart scheduling via the ScottishPower app. You set how much charge you need and by when, and the system automatically optimises when to charge, crediting you down to approximately 9p/kWh. Scottish Power estimates potential savings of up to £374 per year for EV owners driving an average of 700 miles per month. EV Optimise can be added to any Scottish Power tariff except the EV Saver itself.

EV Saver vs Standard Variable

Who should use the EV Saver? EV owners with consistent overnight routines who can reliably plug in before midnight and leave the car charging until 5am. Scottish Power recommends that at least 33% of your total electricity use falls within off-peak hours for the EV Saver to deliver net savings. Below that threshold, the higher daytime rate can wipe out the overnight benefit.

Who should use EV Optimize? EV owners with more variable daily schedules who want the savings without sticking to a strict overnight window. It can be added at no extra cost via the ScottishPower app.

Versus Octopus Intelligent Go: Octopus currently offers an overnight charging rate of approximately 7p/kWh, around 1.5 to 2.5p per kWh cheaper than the EV Saver. On a 60kWh battery charged nightly, that gap is roughly £2 to £3 per week, or £100 to £150 per year for high-mileage drivers. Not decisive, but real.

What Actually Affects Your Scottish Power Electricity Bill?

Your electricity bill is the result of several variables working together. Understanding them gives you genuine control over what you pay.

How much energy you use is the most obvious factor. High-draw appliances like electric showers, tumble dryers, and electric ovens cost significantly more to run than LED lighting or laptop charging. Switching to LED throughout a typical home reduces lighting energy consumption by around 80%. Running appliances during Power Saver windows or Economy 7 off-peak hours reduces your effective unit cost without changing your tariff.

Your tariff and payment method directly affect the rate you pay. Monthly Direct Debit customers access the lowest available cap rates, approximately £131 per year cheaper than cash or cheque payment on a typical dual-fuel bill.

Smart meter vs standard meter matters more than most people realise. Without a smart meter, Scottish Power estimates your usage, and those estimates can be significantly off in either direction. With a smart meter, you pay only for what you actually use, and you unlock EV Saver, Power Saver, and EV Optimise.

Your region affects both your unit rate and standing charge. Differences between cheapest and most expensive distribution regions can run to several pence per kWh. Always check your Tariff Information Label rather than relying on national average figures.

FAQs: Scottish Power Electricity Rates

What is Scottish Power’s current electricity unit rate? 

From 1 April 2026, Scottish Power’s standard variable tariff electricity unit rate is 24.67p per kWh, with a daily standing charge of 57.21p. These are Ofgem price cap averages for Direct Debit customers across England, Scotland and Wales. Your exact rate may differ by region.

Is Scottish Power cheaper than British Gas? 

On standard variable tariffs, the two are near-identical. Both track the Ofgem cap. On fixed deals, prices depend on the specific tariff and postcode. The main practical difference is that Scottish Power supplies 100% renewable electricity on all tariffs, while British Gas only offers green options on selected deals.

How does Scottish Power compare to Octopus Energy? 

Octopus consistently outperforms Scottish Power on customer satisfaction and frequently prices fixed tariffs below the Ofgem cap. In Which?’s 2025 survey, Scottish Power scored below 60% while Octopus was rated a Recommended Provider for the ninth consecutive year. For EV owners, Octopus Intelligent Go offers approximately 7p/kWh overnight versus Scottish Power’s EV Saver at 8.5 to 9.5p/kWh.

What is the Ofgem price cap for 2026? 

From 1 April to 30 June 2026, the cap is set at £1,641 per year for a typical dual-fuel household paying by Direct Debit. The cap limits the unit rate and standing charge suppliers can apply to standard variable tariffs. It does not cap your total bill. Use more energy and you pay more, regardless of where the cap sits.

Does Scottish Power offer fixed-rate electricity? 

Yes. Scottish Power currently offers fixed-rate tariffs locking in your unit rate until April to May 2027, with 100% renewable electricity included. A £50 per fuel exit fee applies if you leave before the contract end date.

How do I check my unit rate? 

Check your most recent Scottish Power bill. Your unit rate and standing charge appear as a line item on every statement. You can also log into your online account and navigate to Tariff Information, or visit scottishpower.co.uk/tariff-information-labels for region-specific rates.

What is the standing charge? 

A fixed daily fee you pay to remain connected to the electricity grid, regardless of how much energy you use. From April 2026, the average electricity standing charge under the Ofgem cap is 57.21p per day, or £208.82 per year before a single unit is consumed. It covers network maintenance, metering costs, and certain government levies.

Can I fix my electricity rate with Scottish Power? 

Yes. With the July 2026 cap forecast to rise, fixing at April 2026 rates may offer meaningful protection. Early estimates suggest the July cap could add around £24 per month to bills. Factor in the £50 per fuel exit fee before committing. A dual-fuel customer needs to save more than £100 versus the variable rate for early exit to make financial sense.

How do I complain to Scottish Power? 

Contact Scottish Power directly and ask for a formal complaint reference. If unresolved after eight weeks, or if they issue a deadlock letter, escalate to the Energy Ombudsman at ombudsman-services.org/energy. Citizens Advice also offers a free energy helpline on 0808 223 1133.

Is Scottish Power 100% renewable? 

Yes. Every domestic and business tariff includes electricity matched to Scottish Power’s own UK wind farm generation. The company operates over 1,157 wind turbines across approximately 38 UK onshore sites and was the first Big Six supplier to generate exclusively from renewables.

Should You Choose Scottish Power? The Verdict.

Scottish Power is a solid, reliable supplier. But whether it’s the right choice depends on what you’re prioritising.

On renewable credentials, it stands out clearly. It was the first Big Six supplier to generate 100% renewable electricity, and every domestic tariff is backed by its own UK wind farms, not open-market certificates.

On price, it’s competitive but rarely the cheapest. The SVT tracks the Ofgem cap like every major supplier. Staying on the default tariff means paying the same rate as British Gas or EDF, without the savings available from the Cap Tracker, Power Saver, or EV Saver tariffs that each require an active switch.

On customer service, the honest picture is that Scottish Power sits in the lower half of the market. It isn’t uniquely poor. British Gas and EDF score similarly. But the gap versus Octopus Energy is consistent and measurable across multiple independent sources.

Choose Scottish Power if you value direct UK-wind-backed renewable electricity, want a comprehensive EV charging package under one roof, or want the financial stability of an Iberdrola-backed supplier. If your priority is the lowest unit rate, the best customer service, or the cheapest EV overnight rate, run a full comparison first. The market may have something better for your specific postcode and usage profile.

A five-minute check on MoneySuperMarket, Uswitch, or MoneySavingExpert could reveal a fixed deal that saves you money well into 2027.
