EDF helps to unlock greater participation in flexibility services
- EDF supports the growth of flexibility services across Great Britain
- Industry rule change enables more homes and small businesses to participate in flexibility markets
- The changes will help customers unlock value from assets such as EVs, batteries and heat pumps while supporting a more flexible electricity system
EDF is working to support the continued growth of flexibility services in the Great Britain, helping more customers participate in energy markets through assets such as electric vehicles (EVs), batteries, heat pumps and other smart technologies.
The commitment supports the growing role of flexibility in balancing the electricity grid as renewable generation and electricity demand continue to increase across the Great Britain. The Government’s Clean Flexibility Roadmap has highlighted the need for a significant increase in flexibility capacity by 2030 to support a more renewables-led electricity system.
A key milestone in enabling wider participation is industry rule change P483, which Elexon introduced in November 2025. The change removes barriers that previously limited access to flexibility markets for many homes and small businesses by allowing the use of assets located at sites which have Non Half-Hourly Metering Systems in Settlement. Until now, flexibility providers could only trade flexibility from customers who were half hourly settled, restricting participation to a relatively small number of customers.
The rule change removes this requirement where assets such as EV chargers and batteries are measured using dedicated asset meters. This allows significantly more customers connected through standard electricity meters to participate in flexibility markets for the first time, helping them lower energy costs, unlock value from their assets and support the grid during periods of peak demand. EDF has been helping scale participation in flexibility services across Great Britain.
Christopher Dalley, Director of Business and Wholesale Services at EDF, said: “This industry rule change is an important step forward for flexibility in the Great Britain making it easier for many more customers to participate in energy markets and unlock value from assets such as EVs and batteries. Flexibility will play a central role in balancing a lower carbon electricity system and supporting EDF’s ambition to help electrify Britain.”
John Lucas, Head of Market Design at Elexon, added: “Opening electricity markets to consumer-led flexibility is key to Great Britain meeting Clean Power 2030 targets. However, we need to support people who cannot provide flexibility until their supplier moves their meter to half-hourly settlement. Through the rule change, Elexon is helping to support these consumers and ensure that they don’t miss out on opportunities, maintaining the momentum in flexibility provision.”
The work forms part of EDF’s wider flexibility portfolio, supporting a growing range of customer and commercial assets participating in energy markets across the Great Britain and helping build a more flexible, lower carbon electricity system.
About EDF
EDF is driving the transition towards An Electric Britain – a secure, affordable, low-carbon future for everyone. As Britain’s biggest generator of zero carbon electricity, we are investing more than £100 million weekly in Britain’s electricity infrastructure. We supply millions of customers with electricity and help homes and businesses switch to electricity for heating, transport and industrial processes.
We operate five nuclear power stations and more than 35 onshore wind farms and three offshore wind farms. Since 2009, EDF has invested almost £9 billion in the nuclear fleet to improve reliability and extend station lifetimes. The five generating stations currently supply about 12% of the UK’s electricity demand.
EDF is building the UK's nuclear renaissance with the construction of a new nuclear power station at Hinkley Point C. We are a minority investor (12.5%) in and major supplier to a replica plant at Sizewell C in Suffolk. Hinkley Point C and Sizewell C will provide low carbon electricity to meet 14% of UK demand and power around 12 million homes. EDF Group companies Framatome and Arabelle Solutions have a presence in the UK and manufacture critical equipment such as reactor pressure vessels and turbines.
EDF is enabling its 5 million customers, both in business and at home, to choose electric solutions that save cash and carbon, whether it is buying an electric car, generating and storing electricity, selling energy back to the grid or installing solar panels or a heat pump. In 2025, EDF’s Customers business was ranked as one of the Sunday Times’s Best Place to Work.
It is also one of the UK’s leading developers of renewable energy through EDF power solutions UK and Ireland. We have more than 2GW of renewable generation in operation and over 10GW in construction, planning and development across a range of technologies including onshore and offshore wind, solar and battery storage.
We are one of the largest suppliers to British business and a leading supplier of innovative energy solutions that are helping businesses become more energy independent. In addition, the company’s energy services business, Dalkia, is one of the UK and Ireland’s largest technical service providers.
