Boilers: Repairs and Maintenance

Question

To ask the Secretary of State for Housing, Communities and Local Government, whether his Department have made an assessment of the potential impact for home boiler longevity of amending Part L of the Building Regulations to mandate (a) boiler inhibitor checks and (b) re-dosing as part of a boiler's required service.

Answer

Approved Document L provides statutory guidance on how to comply with Part L, including advice on adding an inhibitor when a heating system is installed and on providing maintenance information to homeowners through a home user guide.

Checks or re-dosing of inhibitors during routine servicing are outside the scope of the Building Regulations where no building work is being undertaken. The safe installation, maintenance and use of gas systems and appliances are covered by the Gas Safety (Installation and Use) Regulations 2018.

The Government intends to amend Part L and its accompanying guidance in the coming months. The new standards, known as the Future Homes Standard, intends to effectively preclude the installation of gas boilers in new homes and ensure the use of low-carbon heating systems such as heat pumps.
