EDF Energy OVO Energy (October 2026)
Contents
Comparison overview
EDF Energy has lower quoted costs and a better-rated Android app, while OVO Energy leads on measured service and contact performance.
The main choice is between EDF Energy’s lower quoted costs and OVO Energy’s stronger measured contact performance; neither supplier leads across all the main household priorities. EDF has the lower annual estimate shown, a slightly higher Trustpilot score and a better-rated Android app, while OVO has a higher Citizens Advice score, shorter average call centre waits and a higher share of emails answered within two days. EDF’s price advantage is £50 a year, but its lead tracker carries a £100 total exit fee, while OVO’s Simpler Energy has none.
About EDF Energy and OVO Energy
Who is EDF Energy?
EDF Energy is part of the French state-owned EDF Group. Its household supply business sits alongside the group's UK electricity generation activity. This gives EDF a different background from a supplier focused mainly on buying and selling energy, although a household's electricity backing still depends on its tariff.
The company named in its household supply contract is EDF Energy Customers Ltd. That contract covers energy supply and related billing and metering services. Other home energy services can have separate contracts, so buying equipment and choosing an energy tariff are distinct commitments.
Products & services
Who is OVO Energy?
OVO's history starts in 2009. Its household contracts and charging services are offered by OVO Energy Limited. Its current approach combines home energy supply with tools that help households understand their use and move some electricity demand to different times.
Digital account management is part of that approach. The OVO app lets customers see their balance, find bills, send meter readings and track energy use. These are practical account tools; rewards, charging services and home equipment offers have their own conditions rather than being automatic benefits of every energy contract.

Tariffs and pricing
EDF Energy
Simply Tracker Jan28 is EDF’s lowest-priced deal shown at £1,622 a year. Its tracker rates can change, and it carries a £100 total dual-fuel exit fee. The annual estimate is £50 lower than OVO’s Simpler Energy at £1,672 a year, a difference of about £4 a month.
EDF’s lowest fixed estimate is Simply Fixed 2Yr Oct28v7: £1,832 a year for 24 months, with a £200 total exit fee. Simply Fixed Oct27v4 shortens the commitment to 12 months and lowers the fee to £100, but costs £1,997 a year. Standard (Variable), at £1,672 a year, has no exit fee.
OVO Energy
Simpler Energy is OVO’s lowest-priced deal shown. Its variable rates can change, but there is no charge for leaving: its **£0 exit fee contrasts with the £100** leaving charge on EDF’s lead tracker.
OVO’s lowest fixed estimate is 1 Year Fixed + Complete Cover 22 October 2026 at £1,969 a year, with a 12-month term and £100 total exit fee. It costs £137 a year more than EDF’s lowest fixed estimate, or about £11 a month, in return for a shorter commitment and lower exit fee. Fixed deals hold the agreed rates, not the total bill. All named prices here use monthly Direct Debit and cover selected deals rather than either supplier’s whole range.
EDF Energy and OVO Energy: tariff options
EDF Energy tariffs
EDF's Standard (Variable) prices follow Ofgem's quarterly price cap changes, while Simply Tracker follows the cap with discounted standing charges. A tracker can still have a set contract period and leaving conditions despite its changing prices. Simply Fixed Oct27v4 fixes rates for 12 months, while Simply Fixed 2Yr Oct28v7 fixes them for 24 months. The shorter deal ends sooner; the longer deal keeps the agreed rates for longer.[1]
GoElectric suits overnight EV charging without restricting the make of car or charger. Pod Point Plug & Power adds a charger purchase commitment. Heat Pump Tracker instead discounts early-morning and afternoon electricity for qualifying heating systems. FreePhase offers fixed or daily-changing time bands, while the exclusive solar tariffs depend on a qualifying Contact Solar purchase. These smart offers have different equipment and account conditions.[2]
EDF also offers a Smart Charging Bolt-On alongside an eligible electricity tariff. It lets EDF control EV charging and needs an existing EDF domestic electricity account, compatible EV or charger integration, continuing half-hourly smart meter readings, MyAccount and paperless billing. Customers must be 18 or over and live in England, Scotland or Wales. Other charging schedules and non-EDF flexibility schemes cannot run alongside it.[3]
Eligibility
An electric vehicle is required; any EV and charger make can be used; A continuously communicating smart meter, half-hourly reading consent and Direct Debit are required; EDF must be the only flexibility services provider for the EV and home.
Eligibility
An air source heat pump must heat the home; installations by other installers are accepted; A continuously communicating smart meter, half-hourly reading consent and Direct Debit are required.
Eligibility
Paperless bills, Direct Debit and a continuously communicating smart meter with half-hourly reading consent are required; Agree to SMS or WhatsApp tariff messages and complete the dedicated joining form.
Eligibility
Online account access, paperless bills, Direct Debit and a continuously communicating smart meter with half-hourly reading consent are required; Agree to SMS or WhatsApp tariff messages and complete the dedicated joining form; You cannot have been on FreePhase Dynamic within the previous nine months.
Eligibility
A qualifying solar panel or battery purchase through Contact Solar, with the enquiry and purchase after 2 March 2026. EDF electricity supply, MyAccount, Direct Debit and a continuously communicating smart meter with half-hourly reading consent are required. The tariff can be used once per Contact Solar purchase; use within the previous 12 months prevents joining again unless there is an additional purchase.
Eligibility
EDF household electricity supply and solar PV, with or without a battery, but no other generation technology. A Contact Solar lead form submitted on or after 2 March 2026 must result in a new solar or battery installation. Total installed capacity must not exceed 50kW. All relevant solar and battery installations need MCS or Flexi-Orb certificates and DNO letters. Export must be exclusive to EDF, without FiT export or another supplier's SEG payments. A half-hourly export smart meter is required; actual readings must be supplied quarterly or sooner on request if automatic readings fail. Use is limited to once per purchase, with no use in the previous 12 months unless another Contact Solar purchase is made.
Eligibility
EDF household electricity supply and generation from anaerobic digestion, solar PV, onshore wind, hydro or micro combined heat and power, with total installed capacity no more than 50kW. An MCS certificate, a DNO letter and a half-hourly export smart meter are required. Exports must go exclusively to EDF, without FiT export payments or SEG payments from another supplier. Actual meter readings must be supplied quarterly or sooner on request if automatic readings fail.
OVO Energy tariffs and charging add-ons
Simpler Energy is OVO's variable choice, while the dated fixed editions below have 12-month terms. A fixed contract holds the agreed energy rates rather than the amount of electricity or gas used. The Complete Cover edition is distinct from the plain fixed deal; separate boiler-cover offers have their own eligibility and renewal rules, so their promotional benefits are not automatic features of every fixed tariff.
Charge Anytime is an add-on, not a replacement home energy tariff. Its pay-as-you-go choice credits eligible smart charging, while separately paid monthly plans include home charging mileage and public charging vouchers. OVO controls charging times; urgent charging uses the home's normal electricity rate. Greener Electricity is a separate renewable purchasing upgrade, rather than a promise attached to every fixed contract.[4]
Charge Anytime's terms also warn about battery wear: using the service may affect battery performance or lifespan, and compatibility with the vehicle's battery warranty remains the customer's responsibility. The underlying household electricity contract continues if the add-on ends.
Eligibility
A compatible EV or charger , a smart mete r , and an OVO account. if you have solar PV installed at your home, you must have a Solar Compatible Charger. have a Compatible EV or Charger with a working internet connection. have a compatible electricity smart meter that communicates half-hourly data to OVO – currently the main types of smart meters that work with Charge Anytime are SMETS2 meters by any manufacturer, and SMETS1 meters manufactured by Secure.
Customer reviews
EDF scores 4.8 out of 5 on Trustpilot from 260,277 reviews, compared with OVO’s 4.7 out of 5 from 304,542. At EDF, 83% of reviews are five-star and 7% are one-star; OVO’s corresponding shares are 78% and 9%. Both suppliers reply to 99% of negative reviews, typically within 24 hours, although receiving a reply does not necessarily mean the issue is settled.
EDF reviewers often praise polite, understanding staff who help resolve problems, and some report that calls are answered promptly. Frustration centres on follow-through: reviewers describe slow email replies, difficult account communications and billing disputes that take too long to settle, as well as delays arranging appointments or engineer visits.
OVO reviewers praise helpful staff who take ownership of account queries and explain things patiently, while engineer visits attract praise for punctuality, tidy work and clear explanations. Less positive accounts describe long telephone waits, calls not returned and difficulty getting timely help with unexpected bills or account changes.
Which? gives EDF a total score of 58% and OVO 61%. Its customer survey rates both suppliers 2 out of 5 for customer service and value for money, presenting a less positive picture than Trustpilot. In the separate Which? supplier assessment, both receive 9 out of 10 for help for those who need it, while EDF scores 3 out of 12 for contacting your supplier, against OVO’s 8.
Apps and account tools
Both Android apps have 1,000,000+ installs, but EDF is better rated on Google Play: 4.3 out of 5 from 52,185 ratings, against OVO’s 2.9 from 11,054. OVO’s negative ratings slightly outweigh its positive ones, while EDF’s feedback is mostly positive. On iOS, both score 4.6 out of 5, with 189,000 ratings for EDF and 18,000 for OVO, so there is no rating advantage for either supplier on that platform.
EDF says its app gives access to account information, with MyAccount providing another route. OVO describes tools for checking your balance, finding bills, sending meter readings and tracking energy use. OVO customers can also join Power Move through the app to earn points for using electricity at greener times. These tools may appeal if you prefer managing your account without calling, although OVO’s lower Android rating is a drawback for households using that platform.

OVO has the stronger Citizens Advice service result for April to June 2026, scoring 3.65 out of 5 and ranking 6th, compared with EDF’s 2.96 and 10th place. OVO also had a shorter average call centre wait: 47 seconds, against EDF’s 2 minutes 47 seconds. That makes OVO the stronger choice on this measure if shorter telephone queues matter to you.
OVO answered 98.7% of emails within two days, compared with EDF’s 85.4%, and its average webchat response time was 1 minute 7 seconds. EDF’s messaging figures show other routes to help: it answered 91% of WhatsApp messages and 90.9% of SMS messages within two days. These measures describe response speed rather than whether an account problem was resolved.
For the same quarter, 95.08% of OVO’s smart meters were working, compared with 92.67% of EDF’s. The share of smart-meter bills based on actual readings was closer, at 98.44% for OVO and 97.6% for EDF. There was also little difference for traditional-meter bills: 90.24% at OVO and 90.75% at EDF were based on actual readings.
| Billing and metering | EDF Energy — April to June 2026 | OVO Energy — April to June 2026 |
|---|---|---|
| Smart meters working correctly | 92.67% | 95.08% |
| Bills based on readings — smart meters | 97.6% | 98.44% |
| Bills based on readings — traditional meters | 90.75% | 90.24% |
Complaints and resolution
EDF Energy reported 965 complaints per 100,000 customer accounts in Q2 2026, compared with OVO Energy’s 1,775 for the same quarter. EDF therefore recorded fewer complaint events relative to its account base. These figures count complaints, not the number or percentage of individual customers affected.
OVO resolved a higher share of complaints within both reported timescales in Q2 2026: 63.5% on the same or next working day and 90.7% within eight weeks. EDF’s figures were 62% and 86%. This means OVO closed a greater share within those times, despite receiving more complaints per 100,000 customer accounts. Resolution speed does not show whether customers were happy with the outcome.
The separate Citizens Advice measure records complaints to advice bodies and the Energy Ombudsman, rather than complaints received directly by suppliers. For April to June 2026, EDF had 47.7 complaints per 10,000 customers and OVO had 37.5. OVO’s lower rate on this measure contrasts with its higher supplier-reported complaint rate, but the two measures cover different complaint routes and use different denominators.
The complaint themes below are undated, so they are not a Q2 2026 breakdown or a like-for-like comparison. EDF gives percentage shares for its themes; OVO does not.
EDF Energy and OVO Energy: electricity sources and green claims
EDF Energy: nuclear backing and tariff-specific promises
Nuclear power is the largest part of the electricity supplied under EDF Energy Customers Limited's licence. Its annual fuel mix for 1 April 2025 to 31 March 2026 includes nuclear, renewables, gas, coal and other sources. EDF says it sources customers' electricity from its own UK power stations, the wholesale market and other independent generators, and supports independent renewable generators.[1]
The same disclosure separates electricity into Zero carbon, Renewable and All other product groups. For that period, the Zero carbon group was entirely nuclear, while the Renewable group was entirely renewable. These are different kinds of backing: nuclear produces no carbon dioxide at the point of generation, but it is not a renewable fuel. The licence-wide figures in the chart cover the whole disclosed supply, rather than identifying the backing of an individual household tariff.
For households considering electric heating, EDF explicitly says its heat pump tariffs are backed by UK zero-carbon electricity. EDF also identifies zero-carbon backing for GoElectric and Pod Point Plug & Power. These named product promises are more useful when choosing a tariff than assuming the whole company's supply has the same backing.
OVO Energy: renewable buying through Greener Electricity
OVO's electricity supply mix for 1 April 2025 to 31 March 2026 was mainly gas and coal, alongside renewables, nuclear and other sources. This is the annual mix of electricity supplied to customers, not a statement that OVO generates that electricity itself. Its Greener Electricity upgrade has a separate purchasing promise.
With Greener Electricity, OVO says an amount of renewable electricity equal to the customer's use is added to the grid through Power Purchase Agreements with UK-based generators. These are contracts to buy electricity from generators. The household still receives the grid's mixed electricity supply; the promise concerns the amount of renewable power bought to match its use, rather than renewable electricity reaching the home at every hour.
OVO says it stopped using REGO certificates as standard in 2023. REGOs are certificates that record renewable generation. OVO now describes buying power for Greener Electricity customers from renewable generators around the country and investing in new independent renewable power. That named upgrade is distinct from the supplier-wide mix shown here.
OVO also uses charging controls to change when electricity is used. Charge Anytime schedules EV charging around wholesale costs and lower-carbon periods. This changes charging times rather than giving the whole household a renewable electricity allocation.
Our verdict
| If you care most about | Choose |
|---|---|
| The lowest annual tariff estimate shown | EDF Energy |
| Service scores and measured contact performance | OVO Energy |
| Higher user ratings on Android | EDF Energy |
EDF Energy has lower quoted costs and a better-rated Android app, while OVO Energy leads on measured service and contact performance.
EDF may suit households that put more weight on its slightly stronger Trustpilot feedback and better-rated Android app. Customers often value its helpful staff, although slow follow-up on billing disputes and appointments is a recurring criticism. OVO has the stronger measured service and contact performance, with a higher Citizens Advice score, shorter call waits and a higher share of emails answered within two days.
If you expect to need help by phone or email, OVO’s contact results may matter more than EDF’s lower quoted price. EDF may suit you better if you use Android and put more weight on customer reviews, provided you are comfortable with the named tariff’s leaving charge. These different strengths leave neither supplier an all-round winner, and both receive only 2 out of 5 for customer service in the Which? customer survey.

Hi, I'm Rob, and I run Energy-Review.co.uk. I initially started this project in 2018 when I was looking to switch energy suppliers and found there wasn't a website that provided simple, data-backed reviews on all the suppliers available. Since then, I have spent a lot of time (too much, some may say!) looking at all publicly available data about each supplier and writing reviews using this information. These reviews are updated as regularly as possible, and any data is backed up by a source where necessary. I have also started writing guides on various energy-related topics, which hopefully you will find useful. If you find any issues, please use our contact form to let us know.
