British Gas vs OVO Energy: Which Supplier Is Better?

Choosing between British Gas VS OVO Energy is not straightforward because both suppliers serve millions of UK households but focus on different customer needs.

British Gas is the UK’s oldest household energy brand and offers a broad range of services, including gas and electricity tariffs, boiler cover, repairs, smart-home products, solar panels and EV charging. OVO Energy is a newer supplier with a stronger digital-first identity, detailed energy-use insights, fixed and variable plans, renewable upgrades and an unusual EV charging subscription.

British Gas currently says it supplies more than seven million customers, while OVO markets its tariffs to approximately 3.5 million households. OVO has also agreed to sell its UK retail energy business to E.ON, although the transaction remains subject to regulatory approval. Until the deal closes, OVO and E.ON continue to operate independently.

This guide compares British Gas vs OVO Energy across pricing, fixed tariffs, smart plans, EV charging, renewable energy, customer support, apps, business energy and supplier stability.

Quick Comparison: British Gas vs OVO Energy

Tariff prices, discounts and eligibility conditions can change by postcode, meter type and payment method. Customers should therefore request a personalised quote before switching.

British Gas vs OVO Energy: Detailed Feature Comparison

A useful energy comparison should look beyond one advertised unit rate. The final cost and experience depend on standing charges, annual consumption, payment method, smart-meter compatibility, exit fees and how much electricity can be moved to cheaper periods.

The ten most important comparison areas are:

1. Pricing
2. Fixed tariff options
3. Smart tariffs and rewards
4. EV charging support
5. Renewable and low-carbon energy
6. Customer support experience
7. Digital account and usage tracking
8. Solar panels and export tariffs
9. Business energy suitability
10. Supplier stability and overall customer fit

1. Pricing

From 1 July to 30 September 2026, Ofgem’s energy price cap is £1,862 per year for a typical dual-fuel household paying by Direct Debit.

The national average capped electricity rate is 26.11p per kWh, with an electricity standing charge of 57.19p per day. Ofgem’s average gas rate is 7.33p per kWh, with a gas standing charge of approximately 29.04p per day. Actual rates vary by region, payment method and meter type.

The £1,862 figure is not a maximum household bill. It is an illustration based on typical consumption. Higher-use households can pay considerably more.

British Gas Pricing

British Gas’s Standard Variable tariff follows the Ofgem price cap. The supplier also offers fixed products that may be priced above or below the cap depending on wholesale-market conditions and when the customer requests a quote.

British Gas currently promotes fixed tariffs below the July 2026 price-cap level. However, the exact rates are personalised, so customers need to enter their postcode and consumption details to see the actual annual estimate.

OVO Energy Pricing

OVO’s Simpler Energy plan is a standard variable tariff with no fixed contract term or exit fee. Its rates can change when the Ofgem price cap changes.

OVO also offers one-year and two-year fixed plans. Fixed tariffs lock the unit rate and standing charge, but the total bill still depends on how much energy the household uses. OVO advises customers to check their quote for applicable exit fees.

Pricing Verdict

Standard variable pricing is unlikely to produce a major winner because both suppliers are governed by the same price cap.

The real comparison should be between the personalised fixed deals offered at the same address.

• Best for avoiding a contract: Either supplier’s standard variable plan.
• Best for budget certainty: The cheapest personalised fixed quote.
• Most important figure: Estimated annual cost, not only the unit rate.
• Remember: Standing charges apply even when no energy is used.

2. Fixed Tariff Options

Fixed tariffs protect customers from unit-rate increases during the contract period. However, they can become expensive if market prices and the price cap fall.

British Gas Fixed Tariffs

British Gas offers conventional fixed plans as well as its two-year Fix & Fall tariff. Fix & Fall protects customers if prices rise but includes a mechanism that can reduce prices in July 2027 if market conditions fall sufficiently.

British Gas also allows customers to move between its fixed tariffs without paying an exit fee. A fee may still apply when leaving British Gas or moving from a fixed deal to its Standard Variable tariff before the renewal window.

OVO Energy Fixed Tariffs

OVO provides one-year and two-year fixed plans. The one-year option offers a shorter commitment, while the two-year tariff provides longer protection from possible price increases.

OVO’s fixed deals may carry exit fees if customers leave before the contract ends. The amount depends on the selected tariff and should be shown in the customer’s quote and plan documents.

Fixed Tariff Verdict

British Gas has a small advantage because customers can switch between its fixed tariffs without an internal switching fee. Fix & Fall may also appeal to people who want protection against increases without completely losing the benefit of a future market reduction.

• Best for internal tariff flexibility: British Gas.
• Best for a simple one- or two-year choice: OVO Energy.
• Before signing: Check the electricity and gas exit fees separately.
• Do not assume: A fixed tariff means a fixed monthly bill.

3. Smart Tariffs and Electricity Rewards

Smart tariffs and reward programmes are designed for customers who can change when they use electricity. They generally require a working smart meter.

British Gas Smart Options

British Gas offers PeakSave Sundays, providing half-price electricity between 11am and 4pm every Sunday. Customers on the PeakSave Super Sunday tariff can receive the discount between 9am and 5pm.

The supplier also runs PeakSave Green Flex events, during which participating customers receive discounted electricity when more renewable power is expected to be available on the grid.

British Gas also offers selected partner tariffs, such as a Samsung weekend product providing half-price electricity during specified Saturday and Sunday hours. These offers may have extra eligibility requirements.

OVO Energy Smart Options

OVO’s main smart-energy proposition is built around its app, smart-meter insights, EV charging services and member rewards.

OVO has also operated limited-time app offers that allow eligible customers to select free electricity periods. These promotions are not permanent tariff features, so customers should check whether an offer is still open before including it in their decision.

Smart Tariff Verdict

British Gas offers the clearer recurring household electricity discount through PeakSave Sundays.

OVO’s smart products are more closely connected to EV charging, app engagement and personalised energy insights.

• Best for regular weekend savings: British Gas.
• Best for app-based energy management: OVO Energy.
• Best results require: Moving appliances and charging to discounted periods.
• Smart meter required: For most time-based rewards and tariffs.

4. EV Charging Support

EV tariffs should be compared using the off-peak rate, charging window, daytime electricity rate, standing charge and vehicle or charger compatibility.

British Gas EV Tariff

British Gas’s Electric Driver tariff gives customers a 50% discount on the tariff’s electricity unit rate between midnight and 5am.

This is a five-hour window that can suit drivers who mainly charge overnight. The discount applies to household electricity used during the period, not just electricity delivered to the car. The full daily standing charge still applies.

British Gas also offers home charging products through Hive, allowing customers to manage charging and other connected-home services through the Hive ecosystem.

OVO Charge Anytime

OVO has changed Charge Anytime from a simple discounted charging rate into a selection of monthly plans covering both home and public charging.

Its Standard plan costs £27.50 per month and includes up to 175 kWh of smart home charging, which OVO estimates as approximately 700 miles for an average EV. It also includes an annual public-charging allowance.

More expensive plans include larger home-charging allowances, higher public-charging credits and extra benefits. The plans have no long-term contract, allowing customers to cancel or change the subscription. Compatibility and fair-use conditions apply.

EV Charging Verdict

There is no universal EV winner because the two products use different pricing models.

British Gas provides a traditional time-of-use tariff. OVO provides a monthly charging subscription with mileage and energy limits.

• Best for occasional or predictable overnight charging: British Gas.
• Best for combining home and public charging: OVO Energy.
• Best for high-mileage drivers: Compare OVO’s allowance carefully with actual annual mileage.
• Check compatibility: Not every vehicle or charger works with smart charging.
• Avoid comparing only headlines: Include the normal household electricity rate and monthly subscription cost.

5. Renewable and Low-Carbon Energy

The electricity physically delivered to a home comes from the shared national grid. Supplier fuel-mix disclosures explain how the electricity a company purchases or matches is accounted for.

British Gas Fuel Mix

For April 2024 to March 2025, British Gas reported a fuel mix of:

• 55% nuclear.
• 35% renewable energy.
• 8% natural gas.
• 1% coal.
• 1% other fuels.

British Gas reported that 90% of its overall electricity mix was zero carbon. It also disclosed a separate residential renewable product with a 100% renewable fuel mix.

OVO Energy Fuel Mix

OVO’s reported fuel mix for the same period was:

• 73% natural gas.
• 15% coal.
• 4% nuclear.
• 2% renewable energy.
• 6% other sources.

OVO reported carbon intensity of 474g per kWh for this disclosed mix. However, the supplier offers a Greener Electricity upgrade that matches customer electricity consumption with 100% traceable renewable electricity purchased from UK sources.

Green Energy Verdict

British Gas has the stronger default fuel-mix disclosure, with a much larger zero-carbon and renewable share.

OVO customers can choose a renewable upgrade, but its general disclosed fuel mix appears significantly more carbon intensive.

• Best default low-carbon fuel mix: British Gas.
• Best OVO green option: Greener Electricity upgrade.
• Best for customers demanding 100% renewable matching: Compare the terms and price of each supplier’s dedicated renewable product.
• Important distinction: A company’s standard fuel mix may differ from its premium green tariff.

6. Customer Support Experience

Citizens Advice compares suppliers using complaints, contact waiting times, billing and metering performance, and customer commitments.

For January to March 2026, OVO Energy scored 3.30 out of 5 and ranked eighth. British Gas scored 2.61 out of 5 and ranked thirteenth. The median supplier score was 3.26.

OVO performed better than British Gas overall, although neither supplier appeared near the very top of the table.

British Gas had a relatively strong contact waiting-time score but performed poorly in the complaints category. OVO’s individual category scores were more balanced, resulting in its higher overall ranking.

Customer Service Verdict

OVO is the clear winner according to the latest available Citizens Advice comparison.

• OVO Energy score: 3.30/5.
• British Gas score: 2.61/5.
• Overall winner: OVO Energy.
• Important: Customer-service ratings are updated quarterly and can change.
• Best practice: Check independent ratings rather than relying only on supplier-selected reviews.

7. Digital Account and Usage Tracking

British Gas App

The British Gas app allows customers to:

• Track daily, weekly, monthly and annual energy use.
• View consumption in pounds or kWh.
• Manage bills and payments.
• Submit meter readings.
• Top up smart prepayment meters.
• Book boiler services and repair appointments.

Its biggest strength is that energy supply, home services and boiler management can be controlled from the same app.

OVO Energy App

The OVO app allows customers to view bills, submit readings, manage Direct Debits and track household energy use.

Customers who submit half-hourly smart-meter readings receive more detailed insights into when and where energy is being consumed. OVO’s online account also includes downloadable bills, usage graphs and tools for adjusting monthly payments.

Digital Experience Verdict

OVO offers a cleaner energy-focused digital experience and detailed usage insights. British Gas offers a broader service platform that combines energy with boiler and home-services management.

• Best for energy insights: OVO Energy.
• Best for managing energy and boiler services together: British Gas.
• Best basic account management: Tie.
• For detailed graphs: Enable half-hourly smart-meter readings where appropriate.

8. Solar Panels and Export Tariffs

British Gas offers solar panels and batteries through Hive. Its Smart Export Guarantee pays eligible British Gas electricity customers up to 12p per kWh for exported electricity from systems up to 15kW.

Its published export tariffs have no end date or exit fee, although rates are variable and can change.

OVO also offers solar panels, battery storage and Smart Export Guarantee products. Its export options allow qualifying customers to receive payments for unused electricity sent back to the grid, but customers need to compare current rates and eligibility conditions directly.

Solar Verdict

• Best clearly published headline export rate: British Gas.
• Best for an OVO customer wanting one ecosystem: OVO solar and SEG products.
• Check before installing: Equipment costs, battery size, roof suitability and export eligibility.
• Do not choose using export price alone: Compare installation price and expected generation.

9. Business Energy Suitability

British Gas has dedicated small and large business energy services. It offers fixed-term plans, flexible rolling contracts, tailored contracts for half-hourly meters and renewable business electricity options.

Its Energy360 DataView platform gives smart-meter business customers access to daily and half-hourly consumption data.

OVO’s current retail offer is primarily aimed at domestic customers. OVO’s own community guidance states that it does not directly supply non-domestic customers, directing business users toward third-party business-energy services.

Business Energy Verdict

British Gas is the clear winner for business energy.

• Best for small businesses: British Gas.
• Best for large or multi-site users: British Gas.
• Best for half-hourly business data: British Gas Energy360.
• OVO’s main suitability: Domestic households rather than commercial premises.

10. Supplier Stability and Market Position

British Gas is part of Centrica and has operated under one of the UK’s most established energy brands. It currently says more than seven million customers use its gas and electricity services.

OVO is also a major supplier, serving approximately 3.5 million households. In May 2026, OVO agreed to sell its UK retail energy business to E.ON.

The acquisition is subject to regulatory approval and is expected to close in the second half of 2026. Until completion, customers remain with OVO and OVO continues to operate independently.

Stability Verdict

British Gas currently offers greater ownership continuity. OVO remains a large operating supplier, but its ownership and future branding may change after the proposed E.ON acquisition.

• Best for long-established brand stability: British Gas.
• OVO’s current position: Operating independently while awaiting regulatory approval.
• Customer tariffs: Existing terms should continue unless customers are formally notified of changes.
• Overall supplier-failure risk: Both operate at major national scale.

British Gas vs OVO Energy: Pros and Cons

British Gas Pros

• More than seven million customers.
• Strong default low-carbon fuel mix.
• PeakSave half-price Sunday electricity.
• Broad energy, boiler, repair and smart-home ecosystem.
• Dedicated domestic and business energy services.
• Published solar export rate of up to 12p/kWh.
• Ability to move between British Gas fixed tariffs without an internal exit fee.

British Gas Cons

• Lower Citizens Advice customer-service rating.
• EV discount is limited to a five-hour overnight window.
• Some fixed tariffs may charge exit fees when leaving the supplier.
• A large product range can make tariff comparison more complicated.

OVO Energy Pros

• Higher Citizens Advice customer-service score.
• Strong app and detailed energy-use insights.
• One-year and two-year fixed options.
• EV plans combine home and public charging.
• Greener Electricity upgrade available.
• No long-term commitment on Charge Anytime monthly plans.

OVO Energy Cons

• Default disclosed fuel mix has a low renewable share.
• Charge Anytime allowances and compatibility rules add complexity.
• Fixed tariffs can carry exit fees.
• Direct business-energy supply is not its main offering.
• The agreed E.ON acquisition creates uncertainty around future ownership and branding.

British Gas vs OVO Energy: Which Is Cheaper?

Neither supplier is automatically cheaper for every household.

Their standard variable tariffs follow the same Ofgem price cap, so the difference may be relatively small. Fixed-tariff pricing can be more competitive, but results depend on postcode, annual usage and the exact date the quote is requested.

EV owners should calculate charging costs separately. A British Gas customer may benefit from moving household use into the discounted midnight-to-5am period. An OVO customer should compare the monthly Charge Anytime subscription with expected home and public mileage.

For an accurate comparison, use:

• The same postcode.
• The same electricity and gas consumption.
• The same payment method.
• The same meter type.
• The full standing charges.
• All exit or subscription fees.
• Any rewards or off-peak discounts the household will realistically use.

Final Verdict: British Gas or OVO Energy?

British Gas is the stronger all-round supplier for households wanting a traditional, established company with smart electricity rewards, solar-export options, boiler services and business-energy support.

OVO Energy is better for customers who prioritise independent customer-service scores, detailed digital insights and a combined home-and-public EV charging plan.

Overall Winners

• Best for standard pricing: Tie.
• Best for fixed-tariff flexibility: British Gas.
• Best for customer service: OVO Energy.
• Best for EV subscriptions: OVO Energy.
• Best traditional EV time-of-use tariff: British Gas.
• Best default low-carbon fuel mix: British Gas.
• Best app-based energy insights: OVO Energy.
• Best for solar export: British Gas based on its published headline rate.
• Best for business energy: British Gas.
• Best for brand and ownership continuity: British Gas.
• Best overall: British Gas for breadth of services; OVO for digital experience and customer-service performance.

The final choice should be based on a live quote. A supplier may win on customer service or app features but still be more expensive for a specific postcode and usage pattern.
