British Gas and EDF can both be competitive, but there is no permanent winner.

For households, EDF currently has the stronger independent customer-service score and the lower headline EV night rate. In one current London 24-month fixed-tariff snapshot, EDF was also around £80 a year cheaper than the comparable British Gas fixed deal at Ofgem’s typical-use assumptions.

For businesses, the picture is different. British Gas currently ranks ahead of EDF in Citizens Advice’s non-domestic complaints table, while EDF offers distinctive SME products such as one-to-four-year fixes and a Zero Standing Charge option.

Quick verdict: For a household, compare the exact live tariff available to your postcode. For a business, compare the complete commercial contract. The supplier that looks better domestically is not automatically the supplier that offers your company the stronger deal.

British Gas vs EDF at a Glance

The current fixed-price figures above come from a London tariff feed using 2,500 kWh electricity and 9,500 kWh gas, monthly Direct Debit and a single-rate meter. On 21 October, the feed showed EDF Simply Fixed 2Yr Oct28v7 at £1,858.60 and British Gas Fix and Fall Oct28 v4 at £1,938.75. That is useful current evidence, but it is not a personalised quote and should not be treated as a national winner.

The bigger lesson is that “British Gas vs EDF” is not one comparison. It is a comparison between specific tariffs, usage patterns and in the case of businesses commercial contracts.

Is British Gas or EDF Cheaper?

Right now, the answer depends on which products you compare.

In the current London 24-month fixed example above, EDF is cheaper by about £80 a year.

But British Gas also has tracker products priced differently from its Fix and Fall range. Recent regional data for British Gas Cap Tracker Mar2028 v1 showed it sitting roughly £50 below the relevant regional Ofgem cap at typical use.

So it would be misleading to write:

“EDF is cheaper than British Gas.”

The more accurate answer is:

EDF currently has the cheaper deal in some like-for-like fixed comparisons, while British Gas can be stronger on other tariff structures. Your postcode, consumption and tariff choice decide the result.

The current price-cap context

From 1 October to 31 December 2026, Ofgem’s typical dual-fuel Direct Debit benchmark is £1,723 a year.

Average GB rates are:

British Gas and EDF both publish the same Ofgem benchmark and make clear that actual regional rates vary.

The price cap is useful context.

It is not a tariff-comparison tool.

A fixed tariff can sit above or below the current cap, and a household’s actual bill still depends on how much energy it uses.

What Is the Real Annual Cost?

This is the calculation I would use before choosing either supplier.

For electricity:

Annual cost = annual kWh × unit rate + daily standing charge × 365

Then repeat the same calculation for gas.

After that, consider:

• exit fees;
• contract length;
• eligibility;
• any credits or discounts;
• whether rates are fixed or variable.

A lower p/kWh number is not enough.

Suppose Supplier A charges 1p/kWh less but £150 more in annual standing charges.

At 5,000 kWh, the unit-rate saving is only:

£50

So Supplier A is still roughly £100 more expensive before other differences.

At 30,000 kWh, however, that same 1p saving is worth:

£300

Now the lower unit rate could win.

That same principle becomes even more important for business customers.

Which Is Better for Customer Service?

This is one of the clearest areas where the household and business answers diverge.

Household customer service

Citizens Advice’s latest domestic ratings cover April to June 2026.

EDF currently performs better overall and scores better for complaints and billing/metering.

British Gas’ clear strength is contact waiting time.

So I would not simplify this to:

“EDF has good service and British Gas has bad service.”

A more useful conclusion is:

EDF currently has the stronger overall domestic service score, while British Gas performs better for contact waiting.

Business customer service: the result reverses

Citizens Advice now publishes a separate non-domestic league table.

For April to June 2026:

Lower is better.

This is an important distinction competitors often miss:

EDF currently performs better in the domestic Citizens Advice comparison, while British Gas performs better in the non-domestic complaints table.

A household ranking should therefore never be used as evidence that a supplier is also better for a business.

Which Has Better Smart-Meter Performance?

EDF currently has a very small statistical lead.

Ofgem’s latest published figures, measured at 30 June 2026, show:

The gap is only 0.6 percentage points, so I would not make a supplier decision from this alone.

“Operating in smart mode” means the meter is communicating with the supplier and can automatically send readings.

A higher supplier percentage does not guarantee that your individual meter will work perfectly.

The useful conclusion is simply:

EDF currently has a slight smart-mode advantage, but the difference is small.

British Gas vs EDF for EV Charging

This is one area where EDF currently has a more obvious headline advantage.

Current advertised EV rates

EDF confirms its current GoElectric tariff gives seven hours at 6.66p/kWh from 11pm to 6am and works with any EV and charger. British Gas EV Power currently offers 9.5p/kWh from midnight to 5am and also works with any EV/home charger.

At face value, EDF is:

2.84p/kWh cheaper overnight

and gives:

two additional cheap hours.

If you charge 2,400 kWh of EV energy each year entirely in the off-peak period, that headline-rate difference is worth roughly:

£68 a year

before considering daytime rates and standing charges.

Why that still does not make EDF automatically cheaper

Your EV does not consume all the electricity in your house.

If EDF’s daytime price or standing charge is higher for your postcode, part of that £68 could disappear.

British Gas also offers Hive Power+, which can reduce eligible EV charging costs further when used with compatible equipment.

So compare:

EV charging + daytime household electricity + standing charges

rather than the EV rate alone.

Which Is Greener: British Gas or EDF?

This comparison needs more precision than most competitor articles provide.

Both suppliers have now published fuel-mix figures for 1 April 2025 to 31 March 2026, so we can compare the same reporting period.

On the latest company-wide disclosures, British Gas currently has:

• a higher renewable share;
• a higher nuclear share;
• much lower gas exposure;
• lower reported CO₂ emissions per kWh.

But there is another distinction that matters:

Renewable electricity and zero-carbon electricity are not the same thing.

Nuclear is generally treated as low-carbon, but it is not renewable.

And a supplier’s total company fuel mix is not necessarily the mix attached to your individual tariff.

Business renewable products are different again

British Gas’ current disclosure shows:

• Renewable Energy for Business: 100% renewable
• Zero Carbon Energy for Business: 64% nuclear + 36% renewable.

EDF separately offers:

• renewable products backed by renewable generation attributes;
• zero-carbon products backed by nuclear;
• its wider standard supply mix.

If your business needs environmental evidence for reporting, procurement or customer claims, compare the specific product documentation, not the supplier logo.

British Gas Business vs EDF Business: Which Is Better?

For Energy Solutions, this is the more commercially important part of the comparison.

A household tariff table cannot tell a business which supplier offers the better contract.

Business pricing can depend on:

• annual consumption;
• postcode;
• MPAN/MPRN;
• meter type;
• operating pattern;
• contract start date;
• contract length;
• credit profile;
• number of sites.

There is also no household-style Ofgem price cap protecting negotiated commercial contracts.

British Gas Business vs EDF Business at a Glance

British Gas’ standard Fixed Price Energy Plan page currently lists 1–3 year fixed contracts, while its wider SME/commercial route advertises terms from 30 days up to four years. EDF clearly advertises one-to-four-year fixed SME tariffs.

That is why I would compare the actual product offered to the business, not a generic statement such as “British Gas only does three years.”

British Gas Lite vs EDF Small Business

British Gas Lite is designed for smaller, digitally managed businesses.

British Gas currently states the main eligibility characteristics as:

That can work well if the business wants a relatively simple online arrangement.

But an online-only service model will not suit everyone.

If you run a business where energy problems could stop production, affect refrigeration or disrupt several premises, I would consider the support model alongside the rate.

EDF’s SME range

EDF currently advertises three particularly relevant small-business structures:

Fixed for Business Online
Fixed terms from one to four years.

Fixed Online Zero Standing Charge
One-to-four-year fixes with no standing charge, subject to eligibility.

Fixed Renewable
One-to-four-year contracts backed by renewable attributes.

That gives EDF a wider set of clearly differentiated SME tariff structures.

It does not mean EDF will quote the lowest annual cost.

Is EDF Zero Standing Charge Better Than British Gas?

Not necessarily.

This is one of those product names that sounds cheaper before you do the calculation.

Imagine:

The zero-standing-charge tariff loses by £17.50 because its higher unit rate costs more than the standing-charge saving.

These are illustrative rates not current EDF or British Gas prices.

The point is the methodology.

When zero standing charge deserves serious consideration

It becomes more interesting for:

• seasonal premises;
• very low-use shops;
• secondary locations;
• sites left vacant for periods;
• businesses with low annual consumption.

As consumption rises, the unit rate usually becomes more important.

EDF itself presents Zero Standing Charge as an eligible SME option rather than claiming it is cheaper for everyone.

One Mistake We See Businesses Make

A lower headline unit rate can be persuasive because it is the easiest number to compare.

But it can also be the wrong number to base the decision on.

Energy Solutions dealt with this in a real hospitality case.

A restaurant client was close to signing a competing offer because that broker had quoted the lower unit rate.

When we rebuilt both offers using the customer’s real annual consumption, the competing deal’s higher standing charges and wider cost structure made it more expensive overall.

The Energy Solutions option was estimated to save the client around £900–£1,200 per year, and the contract was signed the same day.

That result should not be applied to another business.

The lesson is what matters:

A cheaper rate is not the same thing as a cheaper contract.

That is exactly how I would compare British Gas and EDF for a business.

What Happens When the Business Contract Ends?

Renewal is not an administrative detail.

It can change what you pay.

British Gas

British Gas currently says it contacts customers around 70 days before contract end. Its business pages also show different post-contract routes, including Variable Price Plans, standard variable rates and deemed arrangements depending on the customer’s circumstances.

EDF

EDF’s current SME terms show Freedom for Business as its post-fixed variable product, and its current product pages say fixed tariffs automatically move onto Freedom when the fixed period ends if another arrangement has not been made.

Ofgem warns that deemed and out-of-contract business rates are generally more expensive than negotiated fixed contracts.

This is why I would start looking at renewal options months before expiry rather than waiting for the final week.

The difference between two competitive supplier quotes can be smaller than the cost of spending time on an expensive out-of-contract rate.

Important Business Contract Protections

There are two differences from household energy that business owners should understand.

There is no household-style price cap

The Ofgem domestic price cap applies to qualifying household default tariffs.

It does not cap negotiated British Gas Business or EDF Business contracts.

There is generally no cooling-off period

Ofgem is explicit:

A business energy contract can become legally binding when agreed over the phone, and there is generally no cooling-off period afterwards.

So before saying yes, I would want clarity on:

• rates;
• standing charges;
• start/end dates;
• termination terms;
• what is fixed;
• renewal arrangements;
• broker commission.

This is where commercial energy differs sharply from choosing a domestic tariff online.

What About Broker Commission?

Ofgem advises businesses to check which suppliers a broker compares, whether the broker covers the whole market or a panel, and how commission or fees are charged.

Energy Solutions compares business energy across 30+ UK suppliers, including British Gas Business and EDF, and states that it explains commission and contract terms before customers commit.

That wider comparison matters.

The correct answer to:

“British Gas or EDF?”

may be British Gas.

It may be EDF.

Or neither supplier may have the strongest commercial offer for that particular meter and contract date.

British Gas vs EDF for Large and Multi-Site Businesses

Once consumption becomes large enough, this stops being a simple SME tariff comparison.

British Gas currently offers bespoke contracts for large organisations and flexible purchasing routes for high-volume users. Its business proposition includes Energy360 insights and dedicated large-user services.

EDF also offers fixed, flexible and bespoke procurement for larger organisations.

At this level, I would compare:

A shop using 15,000 kWh should not choose a supplier using the same framework as a manufacturer using 1 GWh.

Which Supplier Is Better for You?

There is no honest one-word winner.

Consider EDF if…

EDF currently deserves a closer look if you are a household prioritising:

• domestic service performance;
• EV charging;
• a current 24-month fixed tariff.

For businesses, EDF is particularly worth comparing if:

• you want up to four years of standard SME price certainty;
• Zero Standing Charge fits a low-use site;
• Fixed Renewable suits your procurement requirements.

Consider British Gas if…

British Gas deserves a closer look if:

• its tracker structure fits your household better;
• contact waiting is important;
• its wider home-energy/Hive proposition matters.

For businesses, British Gas may be more attractive if:

• Lite suits your small online-managed business;
• current non-domestic complaints performance matters;
• its wider commercial/multi-site service model fits your organisation.

How to Compare British Gas Business and EDF Business Quotes

Before requesting quotes, have your annual usage and meter information ready.

For electricity, the most useful information is your:

• annual kWh;
• MPAN;
• meter type;
• current contract end date.

For gas:

• annual kWh;
• MPRN;
• meter details;
• contract end date.

Ask both suppliers to quote on the same:

start date + duration + consumption + meter + payment assumptions.

Then compare:

unit rate + standing charge + applicable costs + contract terms

For multi-site businesses, compare the entire portfolio rather than selecting one site’s cheapest rate and assuming it applies everywhere.

Final Verdict: British Gas vs EDF

For households, EDF currently has more measurable advantages in this comparison.

It scores higher in the latest Citizens Advice domestic ratings, has a slightly higher smart-mode percentage, advertises the lower EV night rate and is cheaper than British Gas in the current London 24-month fixed example we checked.

But none of that proves EDF is cheaper for every household.

Your postcode and tariff still decide the price.

For a business, I would not use the household result at all.

British Gas currently performs better than EDF in Citizens Advice’s non-domestic complaint ranking. EDF has a broader clearly advertised SME tariff range, including four-year fixes and Zero Standing Charge. Both offer commercial renewable and large-user products.

For a household, compare the live tariff. For a business, compare the full contract.

If your business is choosing between British Gas, EDF or another supplier, Energy Solutions can compare live quotes from 30+ UK suppliers, review the rates and standing charges, explain the contract terms and show you the expected commercial cost before you commit.

Frequently Asked Questions

Is British Gas cheaper than EDF?

Not always. In the current London 24-month fixed snapshot checked on 21 October 2026, EDF was around £80 cheaper at typical use. But British Gas has other tariff structures, including tracker products, that can produce a different result. Always compare your postcode and annual consumption.

Is EDF cheaper than British Gas?

EDF is cheaper in some current comparisons, but there is no national permanent winner. Prices change by region, tariff version, payment method and consumption.

Which has better customer service?

For households, EDF currently performs better overall in Citizens Advice’s April–June 2026 data: 2.96/5 and 10th place versus British Gas at 2.61/5 and 14th. British Gas scores better for contact waiting. For businesses, British Gas currently ranks ahead of EDF in the non-domestic complaints table.

Is EDF better for EV charging?

On the current headline rates, EDF GoElectric is stronger: 6.66p/kWh from 11pm–6am versus British Gas EV Power at 9.5p/kWh from midnight–5am. Compare daytime rates and standing charges before deciding.

Which is greener, British Gas or EDF?

British Gas currently reports a higher company-wide renewable share for 2025–26: 45% versus EDF’s 23%. EDF has a large nuclear share, which is low-carbon but not renewable. Businesses should compare the specific renewable or zero-carbon product rather than relying on company-wide fuel mix alone.

Is British Gas Business or EDF better for a small business?

There is no universal winner. British Gas Lite can suit small businesses comfortable with online account management, Direct Debit and smart metering. EDF offers one-to-four-year SME fixes, Zero Standing Charge and Fixed Renewable. Compare the total annual cost and contract terms.

Does EDF offer a zero-standing-charge business tariff?

Yes. EDF currently advertises a Zero Standing Charge option for eligible small businesses. It is not automatically cheaper, because the unit rate still matters.

Does British Gas offer four-year business contracts?

British Gas’ standard Fixed Price Energy Plan page lists one-to-three-year terms, while its broader small-to-medium business route advertises contracts from 30 days up to four years. Availability therefore depends on the product and customer segment.

Is there a price cap for British Gas Business or EDF Business?

No. The Ofgem household price cap does not cap negotiated business-energy contracts.

Can I cancel a business energy contract after agreeing to it?

Do not assume so. Ofgem says there is generally no cooling-off period for business energy agreements, including contracts agreed by phone. Review the terms before accepting.

Which is cheaper for business energy?

There is no reliable national answer. Commercial quotes depend on consumption, meter, location, start date, contract length and other factors. The only meaningful comparison is a like-for-like live quotation using the same business information.
