British Gas vs EDF Energy: Which Supplier Is Better in 2026?

Choosing between British Gas vs EDF Energy depends on what matters most to your household. British Gas offers a broad range of energy tariffs, smart-energy options, home services and EV solutions, while EDF Energy stands out for competitive fixed deals, EV tariffs, smart-energy products and renewable electricity generated in Britain.

This British Gas vs EDF Energy comparison looks at energy prices, fixed and variable tariffs, renewable energy, EV charging, customer service, smart meters, solar export payments, home services and overall value.

Quick Comparison: British Gas vs EDF Energy

The latest Citizens Advice customer-service results for January to March 2026 gave EDF Energy an overall score of 2.90/5, compared with 2.61/5 for British Gas. Both suppliers remain below the strongest performers in the table.

For standard variable tariffs, both suppliers are affected by Ofgem’s price cap. From 1 July to 30 September 2026, the typical annual cap for a dual-fuel household paying by Direct Debit is £1,862, with average electricity rates of 26.11p/kWh and gas rates of 7.33p/kWh. Your actual bill depends on usage and region.

1. Which Supplier Has Better Energy Prices?

There is no permanent winner when comparing British Gas vs EDF Energy on price.

Both companies offer standard variable tariffs that are subject to Ofgem’s price-cap rules. This means comparing the supplier name alone is not enough. You need to compare the actual unit rates, standing charges and estimated annual cost offered for your postcode.

For the period from 1 July to 30 September 2026, Ofgem’s average Direct Debit price-cap rates are:

These are England, Scotland and Wales averages and include VAT. The price cap limits the rates suppliers can charge on default tariffs; it does not mean every household will pay £1,862 because actual costs depend on consumption.

EDF’s Standard Variable tariff follows Ofgem’s price cap, while its fixed and tracker products provide additional options for customers who want something different from a standard variable tariff.

British Gas also publishes Standard Variable pricing alongside its fixed tariff information.

Pricing verdict: Tie for standard variable tariffs. For fixed deals, EDF can be particularly competitive, but customers should compare personalised quotes rather than relying on a supplier-wide price claim.

2. Who Offers Better Fixed Tariffs?

EDF Energy has a strong fixed-tariff proposition and has actively used fixed products to give customers longer-term price certainty.

In March 2026, EDF launched a two-year fixed product designed around the April price-cap level, highlighting its focus on competitive fixed pricing.

EDF explains that fixed tariffs keep the unit rates and standing charges fixed for the agreed tariff period, although the total bill can still rise if you use more energy.

British Gas also provides fixed-rate options, allowing customers to lock in rates for a set period.

A fixed tariff can be useful if you want:

• More predictable energy costs.
• Protection from future increases in capped rates.
• Easier household budgeting.
• Less exposure to wholesale-market movements.

However, fixing is not automatically cheaper. If market prices fall, a customer on a fixed tariff may remain on the higher agreed rate until the contract ends.

Fixed-tariff verdict: EDF Energy wins for customers who prioritise competitive fixed-price options and price certainty.

3. Is EDF Energy Greener Than British Gas?

EDF has a strong renewable and zero-carbon generation proposition. Its EV tariffs are backed by 100% zero-carbon electricity generated by EDF, while the company is also a major operator and investor in low-carbon electricity generation.

British Gas also offers renewable-energy and low-carbon products, including smart tariffs for customers with solar panels, batteries, EVs and heat pumps.

The key difference is how the two suppliers position their energy businesses.

EDF focuses heavily on nuclear and renewable generation as part of its broader low-carbon electricity strategy. British Gas offers customers ways to participate in lower-carbon energy through smart tariffs, solar and other technologies.

This makes the comparison more complicated than simply asking which supplier is “greenest”.

For example, EDF says its EV tariffs are backed by zero-carbon electricity generated in Britain.

British Gas also offers smart tariffs designed around technologies such as heat pumps, batteries, EVs and solar.

Green-energy verdict: EDF Energy wins for customers who specifically want a supplier strongly associated with large-scale zero-carbon electricity generation.

4. Which Supplier Is Better for EV Charging?

This is one of the clearest wins for EDF Energy.

EDF currently offers several EV tariffs, including GoElectric and Pod Point Plug & Power.

Its GoElectric tariff offers off-peak electricity from 11pm to 6am every night at 6.99p/kWh, while Pod Point Plug & Power offers 6.49p/kWh during the same seven-hour period.

EDF expanded its overnight charging window from five hours to seven hours in April 2026, giving EV customers more time to charge their vehicles at the lower rate.

British Gas also offers EV-focused tariffs and smart-energy products. Its smart tariff range includes specialist options for EVs, heat pumps and home batteries.

The right EV tariff depends on:

• How many miles you drive.
• How often you charge at home.
• Whether you have a smart meter.
• Your vehicle and charger setup.
• Daytime electricity usage.
• Tariff exit fees.
• Whether the discounted rate applies to your whole home or specific charging periods.

EV verdict: EDF Energy wins. Its current seven-hour overnight window and low advertised off-peak rates make it particularly attractive for regular home charging.

5. Which Supplier Has Better Customer Service?

EDF Energy currently has the advantage over British Gas in the latest Citizens Advice customer-service comparison.

For January to March 2026, Citizens Advice gave:

EDF ranked 11th while British Gas ranked 13th among the suppliers listed by Citizens Advice.

Interestingly, British Gas scored better for contact waiting time, while EDF performed better overall and scored higher for complaints and billing/metering.

Citizens Advice says its ratings consider complaints, contact waiting times, billing and metering, and customer commitments.

Customer-service verdict: EDF Energy wins, although neither supplier is currently among the strongest performers.

6. Which Supplier Has Better Smart Features?

Both British Gas and EDF Energy have invested heavily in smart-energy products.

British Gas offers specialist smart tariffs for:

• Electric vehicles.
• Heat pumps.
• Home batteries.
• Solar panels.

Its Heat Power tariff, for example, provides half-price electricity during selected off-peak periods for eligible customers with a heat pump or electric heating system.

EDF also offers smart time-of-use tariffs aimed at customers with EVs, heat pumps, solar panels and batteries.

EDF’s Energy Hub allows customers on eligible tariffs to track energy usage and EV charging.

Its GoElectric tariff also provides access to detailed charging information through Energy Hub.

Smart-feature verdict: Tie. British Gas has an impressive range of technology-focused tariffs, while EDF has particularly strong EV and smart-energy tools.

7. Which Supplier Pays More for Solar Exports?

EDF Energy currently has the stronger headline solar-export rate.

EDF’s Export Exclusive 12m V3 offers eligible customers 18p/kWh for exported electricity. It is available for customers with qualifying solar, battery or both, subject to the tariff’s eligibility criteria. EDF also offers an Export 12m tariff paying 15p/kWh.

British Gas currently advertises up to 12p/kWh for eligible electricity customers on its Export Premium tariff for systems up to 15kW. Customers who are not supplied electricity by British Gas may receive a lower export rate.

This makes EDF more attractive for eligible solar households looking to maximise export income.

However, the export rate should not be considered alone. You should also compare:

• Electricity import rates.
• Standing charges.
• Export eligibility.
• Contract length.
• Exit fees.
• Battery requirements.
• Whether you must take electricity supply from the same company.

Solar verdict: EDF Energy wins based on its current headline export rate.

8. Which Supplier Offers Better Home Services?

This is where British Gas has a major advantage.

British Gas is not only an electricity and gas supplier. It also has a large home-services ecosystem covering areas such as boilers, heating and home maintenance.

This can appeal to customers who prefer to manage energy and household services through one established provider.

EDF’s proposition is more heavily focused on energy, low-carbon electricity, EVs, solar and smart-energy technologies.

British Gas can therefore be particularly attractive if you want:

• Boiler support.
• Home heating services.
• Energy supply.
• Smart-energy products.
• EV solutions.
• Solar and battery options.

Home-services verdict: British Gas wins.

9. Which Supplier Is Better for Renewable Technology?

British Gas has specialist products for customers with:

• Solar panels.
• Home batteries.
• Heat pumps.
• Electric vehicles.

Its smart-energy range is designed to help customers move electricity use to cheaper periods and make better use of low-carbon technology.

EDF has a particularly strong proposition around EVs and renewable electricity. Its EV tariffs provide cheaper overnight charging and are backed by zero-carbon electricity generated in Britain.

EDF also offers smart time-of-use tariffs for homes with solar, batteries, heat pumps and EVs.

Renewable-technology verdict: EDF Energy wins narrowly for customers focused on zero-carbon electricity and EV-related technology, while British Gas remains competitive for households wanting a broader collection of home-energy services.

10. Which Supplier Offers the Best Overall Value?

The answer depends on what you want from your energy supplier.

British Gas is a strong option if you value:

• A large established supplier.
• Home-service support.
• Boiler and heating solutions.
• Smart-energy tariffs.
