Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, pursuant to the Answer of 11 June 2019 to Question 258963 on Boilers, what steps he is taking to ensure that domestic boilers comply in situ with the 92 per cent efficiency rate as set out in the Domestic Building Services Compliance Guide, pages 10 and 18.

Local authorities have powers under the Building Act 1984 to enforce the building regulations, including fixed building services such as boiler installations, and have work altered or removed that does not comply. The Building Regulations and Gas Safe rules of registration require that Gas Safe registered businesses comply with their geographical area regulations by notifying any relevant appliances they have installed to the Local Authority. Failure to comply can result in disciplinary action and can ultimately result in traders being struck off the Gas Safe Register.

An initial assessment of Boiler Plus planned for later this year will reveal if there are significant instances of non-compliance. To date, no evidence has come to light to suggest gas boilers below 92% ErP are being installed in English homes.
