EDF Energy in the UK: who they are in 2026
EDF Energy is the UK retail and generation business of Électricité de France, the French electricity utility re-nationalised in 2023 and now wholly owned by the French state. The UK business runs:
- Heysham 1 & 2 nuclear plants (Lancashire) — closure being staged through the late 2020s.
- Hartlepool nuclear plant (Teesside) — running until 2027.
- Torness nuclear plant (East Lothian) — running until 2030.
- Hinkley Point C — the new 3.2 GW plant in Somerset, on track to commission in 2027-2028.
- Sizewell C — under construction, generating from the early 2030s.
- A growing wind and solar portfolio across the UK.
That UK generation footprint is the single most important thing about EDF as a business supplier. Roughly 17% of UK electricity generation comes from EDF nuclear, and they sell their own output rather than buying everything on the wholesale market. That insulates their retail prices from the worst wholesale spikes and is the basis of their 24×7 carbon-free corporate proposition.
The UK retail business serves around 5 million customer accounts, split roughly 75/25 between domestic and business. Headquartered in London with major operational centres in Hove and Exeter.
EDF Business Energy product range 2026
EDF segments its business products by company size and meter type. The 2026 line-up:
Simply Online (micro businesses)
For very small businesses with usage under 25,000 kWh and a simple non-half-hourly meter. Self-service quote and sign-up via the website. Typically 12 or 24 month fixed terms. Price tends to be 1-2p/kWh higher than the brokered route — the convenience tax is real.
Standard Variable Business
The deemed/out-of-contract product you get rolled onto if you let your fixed contract expire without renewing. Avoid: rates are typically 5-12p/kWh higher than a fresh fixed quote. See our deemed contracts guide for the full cost.
Fixed Term Business (the main SME product)
The flagship product for SMEs and mid-market customers. 12, 24, 36, 48 or occasionally 60 month fixed contracts. Per-kWh rate and standing charge locked. This is what 80%+ of EDF’s business book sits on.
Half-Hourly contracts
For sites with peak demand >100 kW, EDF offers proper HH contracts with the usual SME-bracket products plus optional flex-purchase contracts where the customer (or their consultant) buys the power in tranches across multiple wholesale visits. EDF Trading on the back-end gives them genuine market presence here. See our HH meters guide for whether HH suits you.
Industrial & Commercial / Drax-style 24×7 carbon-free
For 1m+ kWh corporate buyers reporting under SBTi or RE100, EDF offers time-stamped 24×7 carbon-free electricity contracts: every half-hour of consumption is matched to a half-hour of nuclear, hydro or wind generation. Few UK suppliers can do this credibly because few have their own carbon-free generation fleet. Drax, Ørsted and EDF are the main credible providers.
EDF Business Energy pricing 2026
For a typical SME on a fresh 24-month fixed contract in 2026:
- Electricity unit rate: 23-27p/kWh for under-50,000 kWh sites, 18-22p/kWh for 50,000-250,000 kWh, 14-19p/kWh for HH-metered users.
- Standing charge (electricity): 40-60p/day for SMEs.
- Gas unit rate: 6-9p/kWh for SMEs.
- Standing charge (gas): 28-42p/day.
EDF tends to be most competitive in the 50,000-250,000 kWh medium band. They are usually mid-pack on micro quotes (Yu, BG Lite and Octopus often beat them), and very competitive at the top end where their generation hedge matters.

The Drax-style 24×7 carbon-free option
For corporates targeting RE100, SBTi or science-based net-zero, the gold standard is time-stamped 24×7 carbon-free matching: every megawatt-hour you use is matched to a megawatt-hour of carbon-free generation in the same half-hour, in the same grid region. Standard REGO contracts only match annual volumes — you can be 100% REGO-backed on paper while running on gas-fired generation at 6pm in winter.
EDF can deliver real 24×7 matching because their UK nuclear fleet runs at high baseload (Heysham, Hartlepool, Torness) and they have a growing wind portfolio for shoulder hours. The premium over a vanilla fixed contract is typically 0.5-1.5p/kWh. Drax offers a similar product backed by their Cruachan pumped-storage and Yorkshire biomass output.
For most SMEs this is overkill — standard REGO-backed renewable is fine. See our renewable business energy guide for when 24×7 matters.
The myEDF Energy Hub: multi-site portal
EDF’s business portal is one of the better Big Six offerings:
- Site-by-site usage and bill view across all your meters.
- 30-minute granularity for HH meters; daily granularity for smart-meter NHH.
- CSV export of usage data and CO2 emissions.
- Spend forecasts and renewal-window alerts.
- Submit meter reads, request bill adjustments, raise service tickets.
- API endpoints for very large customers integrating with internal BI.
For a 10-50 site portfolio, this is a significant productivity win versus suppliers still emailing PDFs. Octopus’s Kraken portal is sharper and Pozitive’s newer dashboard is catching up, but EDF’s is genuinely usable.
Customer service and complaints
EDF’s customer service is mid-pack: better than British Gas Business and ScottishPower, worse than Octopus, E.ON Next or Yu Energy. The 2026 picture:
- Trustpilot: 1.4 / 5 (heavily skewed by domestic complaints — business reviews are slightly better).
- Citizens Advice complaint score: middle of the Big Six.
- Average phone wait time: 6-12 minutes.
- Account managers for 100,000+ kWh customers; small SMEs go through general business support.
Most issues we see in practice are billing setup errors in month 1 of a new contract (incorrect VAT rate, wrong CCL flag, missing reads) which the team resolves within 2-3 weeks. Major outage handling is solid because their generation operations team has serious technical depth.
Pros: where EDF Business genuinely wins
- Strong UK nuclear-backed generation portfolio — lower wholesale-spike exposure.
- Credible 24×7 carbon-free option for RE100 / SBTi reporters.
- Solid pricing in the 50,000-250,000 kWh medium-band sweet spot.
- Genuine multi-site portal with HH 30-minute data.
- French state ownership = effectively zero supplier-failure risk.
- Hinkley Point C coming online in 2027-2028 strengthens the long-term hedge.
- Established relationships with the largest UK industrials.
Cons: where EDF loses out
- Mid-pack customer service — Octopus and E.ON Next score noticeably better.
- Rarely the cheapest on micro-business quotes.
- Standard Variable Business deemed rates are punitive (don’t roll onto them).
- Smart meter installation backlog still real for some regions in 2026.
- Less developed EV fleet proposition than Octopus or Pod Point/EDF JV (Pod Point is now an EDF subsidiary, but the integration is still maturing).
Who EDF Business suits best
- Mid-market businesses (50,000-500,000 kWh): pricing sweet spot.
- Corporates with strict carbon reporting: 24×7 carbon-free contracts.
- Multi-site portfolios: portal handles 5+ sites well.
- Risk-averse boards: state-backed parent + UK generation hedge.
- Heavy industrial users: half-hourly + flex contracts available.
EDF Business Energy alternatives in 2026
- Octopus Business — best-in-class service and tooling.
- British Gas Business — biggest network, see our British Gas Business review.
- SEFE Energy — usually cheaper for 50,000+ kWh and gas-heavy users.
- Drax — 24×7 carbon-free competitor with biomass + pumped storage.
- ScottishPower — wind-heavy generation, similar tier.
- Yu Energy — cheaper for sub-15,000 kWh sites.

How to switch to EDF Business (or away from them)
Standard process: 6-month renewal window opens, sign a Letter of Authority (see our LoA guide), receive quotes, sign new contract, 28-day cooling-off, registration on the new supplier completes within 3-6 weeks (faster for HH meters). EDF accepts incoming from any UK supplier and will not block valid switches. Their loss-saves team will sometimes counter-offer in the last 30 days — worth a phone call before signing elsewhere.
Frequently Asked Questions
For mid-market businesses (50,000-250,000 kWh) EDF is often within 0.5p/kWh of Octopus and noticeably cheaper than British Gas. For micro businesses (under 5,000 kWh), Yu Energy and EDF Simply Online compete closely with British Gas Lite. The right answer depends on your meter, postcode and usage profile — run a free comparison to see your numbers.
Yes for Scope 2 GHG accounting. UK nuclear generation has near-zero operational carbon (around 6 g CO2e/kWh lifecycle, vs 400+ g for gas). EDF’s 24×7 carbon-free product is also accepted under SBTi and RE100 reporting because it’s time-stamped — not just an annual REGO match.
Hinkley Point C is on track to start commercial operation in 2027-2028. It will add 3.2 GW of UK nuclear baseload — about 7% of UK electricity demand. Once running, it strengthens EDF’s ability to offer competitive long-term fixed contracts and 24×7 carbon-free deals. It does not change your existing contract terms.
Yes — EDF supports SMETS1 and SMETS2 smart meters across all their business products. They can also install one for free if you don’t have one yet. Smart meter readings unlock more accurate billing and access to their HH-style time-of-use products for eligible sites.
Yes — like all UK business energy suppliers, EDF charges a termination fee equal to roughly the lost margin on the unused contract term. Typical: 2-4p/kWh × remaining annual usage × remaining months / 12. Always read the contract’s termination clause before signing and avoid mid-term switches unless you’ve modelled the break-even.
Extremely safe. EDF Energy UK is wholly owned by Électricité de France, which was re-nationalised by the French government in 2023. Investment-grade D&B credit rating, deep UK generation assets, and effectively zero supplier-of-last-resort risk. Their wholesale exposure is hedged by their own nuclear output.
