EDF backing An Electric Britain with £15bn investment planned for 2026-28
- EDF continued to be a major investor in Britain in 2025, investing over £5bn to strengthen longer term energy security, whilst generating £1.9bn in earnings (EBITDA). Over the next three years EDF plans to invest a further £15bn in the UK across its different businesses.
- EDF remained Britain’s biggest generator of zero carbon electricity in 2025(1), with its nuclear fleet providing around 12% of the UK’s total power demand. EDF is also one of the UK’s largest energy suppliers, serving around five million residential customer accounts and holding a 4.8-star Trust Pilot rating, with over 150,000 reviews at five stars.
- Workers building the Hinkley Point C (EDF 76.7%) nuclear power station lifted the 245-tonne steel dome onto Unit 2 in July 2025. The project continues to generate huge social and economic benefits, with 26,000 jobs supported across Britain in 2025. The project is organised on Unit 1 becoming operational in 2030.
- The Government’s decision to approve the Sizewell C project in 2025, supported by private investment, is a major vote of confidence in the UK nuclear sector. EDF will play its part as a minority shareholder (EDF 12.5%), sharing learnings from Hinkley Point C and supplying the project through EDF Group companies Framatome, Arabelle Solutions, EPR Engineering and EDF Nuclear Services.
- EDF continues to invest in its national apprenticeship, graduate and industrial training programmes and its leadership in this area is enabling 5,000 people to kick start their careers across the UK.
Please follow this link to the EDF Group media release relating to the Group’s Annual Results for 2025, which were published this morning. These relate to the consolidated performance of EDF Group and include a summary of EDF’s performance in the UK.
In the UK business, earnings before interest, tax, depreciation and amortisation (EBITDA) were £1.9bn (versus £2.9bn in 2024). The decline in earnings compared to 2024 was caused mainly by lower nuclear output, down 4.4TWh on 2024 due to an extended outage at Hartlepool power station, and lower realised prices than in 2024.
Net investment in the UK business was around £5billion, marking a 30% increase compared to 2024. Over the past eight years EDF has invested over £2 in the UK for every £1 made in earnings (EBITDA*), running existing and building future nuclear infrastructure and in helping its customers save cash and carbon.
Simone Rossi, CEO of EDF in the UK, said: "EDF is continuing to invest heavily in powering, supplying and building an electric Britain. Our UK strategy is to deliver a long term nuclear and renewables generation business, and to meet the evolving needs of our customers as more and more transition away from fossil fuels to using cleaner, more secure and affordable electricity.”
EDF continues to invest in its national apprenticeship, graduate and industrial training programmes and its leadership in this area is enabling 5,000 people to kick start their careers across the UK. The Hinkley Point C project in Somerset has now trained over 1,700 apprentices; it has also provided opportunities for nearly 1,000 people to experience a 16-week training programme, with over half gaining employment on the project. Sizewell C, in which EDF owns a 12.5% stake, is due to hire 1500 apprentices over the coming years. In its nuclear business, EDF currently has over 500 people in its early careers programmes, including apprentices, graduates and industrial placements.
Highlights for the UK:
Customers
EDF remained one of the UK’s largest energy suppliers, serving around five million customer accounts. Improving customer experience and reputation remained central to EDF’s strategy. The company holds a 4.8-star Trust Pilot rating, with over 150,000 reviews at five stars and was recognised as a Top 10 employer in The Sunday Times Best Places to Work. Its Sunday Saver programme helped over 260,000 customers reduce bills by shifting electricity use, delivering £5.2 million in savings and more than 17 million free hours of power.
The company expanded its flexible tariffs and offers to help customers save money through Britain’s increasingly smart energy systems. Its innovative and simple FreePhase offers smart time-of-use tariffs with three energy rates - red, amber, and green - designed to help customers save by shifting electricity usage to cheaper times. The acquisition of Pod further expanded EDF’s offering in the growing electric vehicle charging market.
The Business & Wholesale Services team retained its position as the number one energy supplier to large businesses in Great Britain and secured over 2,500 MW of grid-scale battery optimisation agreements, bringing total battery capacity under contract to more than 5,000 MW, the largest volume in the UK. These agreements support system balancing and market optimisation, consistent with EDF’s refreshed purpose to deliver an electric Britain.
EDF also supported business customers to decarbonise and reduce energy costs through a growing portfolio of partnerships and commercial agreements, including long-term Power Purchasing Agreements (PPAs).
To support vulnerable customers, EDF set aside £30 million over winter, including providing electric goods such as heated throws, self-heating mattress toppers and soup makers through its Winter Warmth Choices scheme, supporting 17,000 customers. In 2025, EDF also supported 75,000 customers with debt advice, income maximisation, energy efficiency guidance, debt clearance and financial assistance payments. This was in addition to £119 million spent on the ECO and GBIS (insulation) schemes and £54.6 million on the Warm Home Discount rebate scheme in 2024/25.
Nuclear Operations
In 2025, EDF’s Sizewell B and Torness power stations performed strongly and total nuclear output from the five generating stations was 32.9TWh, 12% lower than 2024 due mainly to an extended outage at Hartlepool power station. The fleet provided around 12% of the UK’s total power demand, retaining EDF’s position as Britain’s biggest generator of zero carbon electricity. EDF aims to maintain output around this level for as long as it remains safe and commercially viable to do so. Investment to support that goal will total £1.2bn over the next three years (2026-28).
In September 2025, a further year was added to the forecast lifetimes of Heysham 1 and Hartlepool, taking them out until March 2028. The current forecast for Heysham 2 and Torness is 2030. Work continues to agree a commercial model that is required to support a 20-year Sizewell B life extension (2035-2055) and unlock £800m of investment in the station.
Hunterston B and Hinkley Point B power stations are on schedule to transfer into UK Government ownership in 2026 after the removal of 1232 fuel channels was completed in line with the plan and budgets agreed with Government.
The current nuclear fleet has been supporting UK economic growth since 1976. On 5 February 1976 the first of the seven AGR power stations, Hinkley Point B, was synchronised to the National Grid for the first time, closely followed by Hunterston B. Over the last 50 years the AGR fleet has delivered nearly 2000TWh of zero carbon electricity (total UK demand in 2025 was estimated at 273TWh), supported tens of thousands of jobs and delivered around £110billion of economic value. More information is available in the annual update published on 21 January.
Hinkley Point C
Hinkley Point C continued to make good progress during 2025. The 245-tonne steel dome was lifted onto Unit 2 in July 2025. The 14-metre-tall dome closes the 44-metre-high reactor building, allowing its fit-out to accelerate. The second reactor pressure vessel was dispatched from Framatome’s factory at Saint Marcel in early December. The 13-metre high vessel weighs in at 500 tonnes and will house the reactor core and all associated components. Civil construction on Unit 1 is now 95% complete. Installation rates on Unit 1 for the mechanical, electrical, heating and ventilation services (MEH) phase doubled in quarter four.
The project continues to generate huge social and economic benefits, with 26,000 jobs supported across Britain during 2025 and over 14,000 people trained so far, including 1700 apprentices.
Lessons learned during the construction of Hinkley Point C continue to be shared with the Sizewell C project in Suffolk, to ensure the economic benefits of repeating a proven design are delivered.
EDF Power Solutions (Renewables)
EDF power solutions UK and Ireland has continued to grow across all technologies as it makes progress towards its goal of reaching 10 GW by 2035. It currently has 50 operational sites, with an operating capacity of 2GW, and employs 640 people directly.
With its JV partner ESB, it completed commissioning of the 450 MW Neart na Gaoithe (NnG) offshore wind project, 15km off the coast of Scotland. Development of the Codling offshore wind project continues in the Republic of Ireland with our JV partner, Fred Olsen. In the Celtic Sea, together with ESB, we successfully secured the rights to develop the Gwynt Glas Floating Offshore Wind Farm through The Crown Estate’s Leasing Round 5.
EDF power solutions also completed commissioning of the Bredbury and Tye Lane energy storage systems located in Greater Manchester and Suffolk, with further battery projects in construction in Essex, Cornwall and Norfolk. EDF power solutions is also continuing to expand its solar portfolio with the construction of Bloy’s Grove solar farm in Norfolk and Tye Lane solar farm in Suffolk. The acquisition of the consented DCO solar project Gate Burton, in Lincolnshire, and launch of South Brooks DCO project, in Kent, added to this growth.
In onshore wind, construction continued at the Stranoch wind farm in Dumfries and Galloway, with the main component deliveries being completed to site in Q4 2025.
Dalkia
Dalkia UK had a good year, growing to more than 5,200 employees in the UK following the start of the facility management contract with EDF’s nuclear power stations that started on 1 July. The company also continued to support its clients in their electrification and decarbonisation efforts.
The order book is strong with key contracts to be started this year, including the British Museum’s new ‘Net Zero Energy Centre’ and the Great Ormond Street Hospital’s new Children’s Cancer Centre in London.
