There are two tables (one for domestic households and micro-businesses and one for all other businesses). This will show you how you can contact these providers and take part in the service with them. It also shows if they are a member of the Flex Assure compliance scheme or aligned to the HOMEflex voluntary standards for flexibility service providers.

What is FlexAssure / HOMEflex code of conduct?
|
Image
|
FlexAssure is a code of conduct and compliance scheme for flexibility service providers serving business customers. |
|
Image
|
HOMEflex is a code of conduct for flexibility providers serving households and micro-businesses. There is no compliance scheme in place for HOMEflex yet. |
Flexibility providers have self-certified whether their organisation is aligned to either the FlexAssure and/or HOMEflex voluntary code of conducts. These codes of conduct ensure customers are protected and can trust their flexibility provider to adhere to a minimum set of standards. The ESO has no responsibility for auditing compliance with FlexAssure or HOMEflex.
