What is Boiler Plus?

Boiler Plus is the 2018 update to Part L of the Building Regulations for England, raising minimum efficiency and control requirements for gas-boiler installations. All new gas boilers in homes must be at least 92% ErP efficient and gas combination boilers must be installed with one of four additional efficiency measures (e.g. weather compensation, flue-gas heat recovery). The rules are enforced through Gas Safe registration.
