What's changing and how will it affect your work?
A revised version of Approved Document L (Part L) of the Building Regulations has been published which will take effect from 15 June 2022. With this revision there are a number of changes to guidance and requirements for boiler regulations covering both the new build and retrofit markets.
With regards to existing dwellings the main points are:
Complete New System Installations require:
Boiler Swaps require:
Document BS 7593:2019 – Code of practice for the preparation, commissioning and maintenance of domestic central heating and cooling water systems – has been incorporated into Part L guidance, so what was best practice advice will become a requirement.
As well as cleansing and flushing the system when installing a new boiler to remove debris and sludge and then treating the water with inhibitors, an in-line filter must be installed in the circuit to capture particles and prevent them from entering the boiler.
Sludge and debris in the system is a major cause of boiler breakdowns. By installing a filter to prevent the build-up of sludge, heating systems will be more energy efficient and reliable, leading to lower fuel bills, reduced breakdowns and lower carbon emissions.
For more information you can find the Approved Document L here. Please note this applies to England only.
