A smarter grid starts with trust. Flex Assure guarantees that the companies helping you shift your energy usage treat you fairly, clearly, and professionally.
Trusted, verified flexibility providers
Energy flexibility isn't just an industry term - it's a vital adaptation that benefits every household and sustains the national grid.
Businesses and households adjust when they use electricity - running equipment at off-peak times or responding to smart grid signals automatically.
By using energy when renewables are plentiful and avoiding peak demand, flexibility significantly reduces bills and drives the UK toward net zero.
Flex Assure sets enforced standards. Every provider signed up to our scheme treats customers fairly, transparently, and with full accountability.
