These Regulations amend the Heat Networks (Market Framework) (Great Britain) Regulations 2025 (the “2025 Regulations”). Regulation 56 of the 2025 Regulations requires persons holding a “heat network authorisation” to be members of a redress scheme in relation to complaints from domestic and certain business consumers in connection with the supply of heating, cooling or hot water. These Regulations clarify the business consumers to which that requirement relates.
