The comparison reflects current supplier products, published fuel disclosures and Citizens Advice’s January–March 2026 ratings.
Tariffs, rates and eligibility vary by postcode, meter, payment method and consumption. Always compare personalised annual costs rather than relying on national illustrations.
1. Which Supplier Has Better Energy Prices?
Neither supplier is always cheaper. Their standard variable tariffs must remain within Ofgem’s cap, while fixed prices, tracker discounts, standing charges and household usage decide the real winner. Compare personalised quotes using identical consumption.
From 1 July to 30 September 2026, Ofgem’s cap is £1,862 for a typical dual-fuel Direct Debit household. Average electricity costs are 26.11p/kWh plus 57.19p daily; gas averages 7.33p/kWh plus 29.04p daily. The cap limits rates, not total bills.
EDF’s Standard Variable tariff changes with the price cap and has no fixed contract or exit fee. EDF also offers Simply Tracker, which follows cap changes but discounts standing charges by £25 per fuel, saving a dual-fuel customer £50 over a year. Its tracker carries a £25 exit fee per fuel.
OVO’s Simpler Energy tariff is its flexible standard variable plan. It has no exit fee and continues until the customer fixes or switches. OVO also sells fixed tariffs that may sit below or above future capped prices depending on the quote date and market conditions.
Pricing verdict: EDF has the more distinctive price-cap tracker because the standing-charge saving is guaranteed. OVO may still be cheaper on a personalised fixed quote, but there is no permanent standard-tariff winner.
2. Who Offers Better Fixed Tariffs?
OVO has the clearer fixed-tariff menu, with published 12- and 24-month choices and transparent exit fees. EDF’s Simply Fixed protects rates and standing charges, but exact terms depend on the live offer.
OVO’s current range includes a one-year fixed tariff with a £50 exit fee per fuel, a one-year option with boiler cover, a greener electricity version, and a two-year fix with a £95 exit fee per fuel. All these products can work with Charge Anytime.
EDF’s Simply Fixed locks rates and standing charges and includes Sunday Saver access. Exit fees apply, with the amount shown in the contract. Fixed rates do not fall when the Ofgem cap drops.
Fixed-tariff verdict: OVO wins for transparent choice and the option to fix for two years. EDF is stronger for customers who prefer a tracker or want specialist tariffs rather than a conventional long fix.
3. Which Supplier Has Better Smart Tariffs and Rewards?
EDF offers the broader smart-tariff range, while OVO provides simpler behaviour-based rewards. EDF covers EVs, solar, batteries and heat pumps; OVO focuses on Charge Anytime, Power Move and Beyond.
EDF’s FreePhase tariffs use red, amber and green pricing periods and may provide occasional free-electricity windows. Its heat-pump tariffs discount electricity by 10p/kWh from 4am–7am and 1pm–4pm. Most products require a smart meter sending half-hourly data.
EDF’s Sunday Saver can award later free-electricity hours when eligible customers reduce usage during challenges, although availability varies.
OVO’s Power Move encourages customers to shift usage away from selected peak periods and can provide rewards or prize entries. Beyond adds benefits such as energy-saving rewards, access to selected offers and the ability to build credit towards qualifying OVO solar panels.
Smart-energy verdict: Choose EDF for specialised time-of-use tariffs. Choose OVO if you prefer straightforward app-based challenges and rewards without managing several daily price bands.
4. Is EDF or OVO Better for EV Charging?
EDF is better for drivers who want a low, predictable overnight unit rate that works with any EV and charger. OVO is more flexible for motorists who want smart charging at different times or a monthly package combining home mileage with public charging, but its PAYG rate is substantially higher.
EDF’s GoElectric tariff offers seven off-peak hours from 11pm to 6am at 6.99p/kWh. EDF says its EV range has off-peak rates between 6.49p and 6.99p/kWh, depending on the product, and works with any electric car or charger.
OVO’s Charge Anytime PAYG rate is 14p/kWh. Monthly plans start at £27.50 for 700 home-charging miles and a £120 public-charging voucher; higher tiers add mileage and benefits.
OVO credits eligible managed EV charging; urgent charging and mileage above the allowance use the normal home rate.
EV verdict: EDF wins for the lowest simple published rate and a seven-hour household-wide window. OVO suits drivers who value anytime scheduling and bundled public charging.
5. Which Supplier Is Greener?
EDF has the lower-carbon disclosed fuel mix because nuclear supplies more than half its portfolio. OVO questions certificate-based green claims, but its 2024–25 disclosure contains much more gas and coal.
EDF reported 54.8% nuclear, 18.2% renewable, 21% gas, 4.2% coal and 1.8% other sources. Its disclosed carbon intensity was 135g CO₂/kWh. Selected EDF zero-carbon products are nuclear-backed, while renewable products are matched with renewable generation.
OVO reported 73% gas, 15% coal, 4% nuclear, 2% renewable and 6% other, with carbon intensity of 474g CO₂/kWh. Its paid Greener Electricity upgrade supports directly sourced renewable power.
Green-energy verdict: EDF wins on disclosed carbon intensity and zero-carbon supply. OVO’s approach may appeal to customers who support its criticism of certificate-based claims, but the published fuel-mix numbers clearly favour EDF.
6. Who Has Better Customer Service?
OVO currently performs better in Citizens Advice’s comparison, with stronger complaints and billing results. Waiting-time scores are equal, and both receive full marks for customer commitments. The figures cover January to March 2026.
OVO ranks eighth with 3.30/5: 2.5 for complaints, 3.2 for waiting time, 3.8 for billing and metering, and 5.0 for customer commitments. EDF ranks eleventh with 2.90/5: 2.0 for complaints, 3.2 for waiting time, 3.0 for billing and metering, and 5.0 for commitments.
Customer-service verdict: OVO is the stronger choice based on the latest independent data, particularly for billing and metering. EDF is not far behind, but its lower complaints and billing scores reduce its overall position.
7. Which Supplier Pays More for Solar Exports?
OVO offers the highest headline solar-export rate, but strict installation and supply conditions apply. EDF’s 15p/kWh fixed option for eligible systems and 18p/kWh installation-linked rate may suit more solar owners.
EDF Export Exclusive 12m V3 pays 18p/kWh when qualifying solar panels, a battery or both are purchased through EDF. Its Export 12m tariff pays 15p/kWh, while variable options pay 5.6p to EDF electricity customers or 3p to other eligible generators. These tariffs have no exit fees.
OVO’s standard SEG rate is 4p/kWh. SEG Beyond Exclusive pays 12p/kWh to qualifying OVO electricity and Beyond customers. SEG Install Exclusive pays up to 20p/kWh when OVO supplies the home and installs both solar panels and battery storage; solar-only installations receive 15p/kWh when all conditions are met.
Solar verdict: OVO wins for the 20p headline rate. EDF may be better for households with existing panels because its 15p option is stronger than OVO’s standard and Beyond rates.
8. Which Supplier Has the Better App and Home Services?
Both apps handle essential account tasks. EDF emphasises energy, PAYG and EV information, while OVO combines usage insights with offers and Beyond rewards.
The EDF app supports bills, Direct Debits, meter readings, photo readings, usage graphs, smart-meter insights, EV information and PAYG top-ups. Its dashboard flags account issues such as payment, tariff-renewal or meter actions.
The OVO app displays usage insights, bills and readings, manages Direct Debits and provides access to offers, Power Move and Beyond rewards. Half-hourly smart-meter readings unlock more detailed breakdowns.
OVO offers boiler, appliance, electrical and plumbing cover alongside solar and EV products. EDF offers boiler services, insulation, heat pumps, solar, batteries and EV charging, but OVO’s insurance-style cover is broader.
