Installers urged to prepare for changes to Part L

Water treatment manufacturer Fernox is calling on heating and plumbing professionals to ensure that they are implementing the best practice guidance outlined in BS 7593:2019 before it becomes mandatory. The code of practice is due to be introduced into Part L of the Building Regulations in June 2022.

Approved Document L of the Building Regulations, which looks at the conservation of fuel and power, is being updated to include additional measures that will help to keep central heating systems working at optimum efficiency. The changes include ensuring an in-line filter is installed, checking inhibitor levels on site annually and conducting laboratory analysis of the system water, or re-dosing, every five years.

Fernox recognises that many tradespeople will already be taking steps to correctly clean, guard, protect, maintain and test central heating systems – but is encouraging engineers to carefully consider the water treatment products that they are using.

Richard Crisp, head of chemistry at Fernox, says: “The Fernox range of water treatment products has been designed to offer engineers an effective, easy to use solution for every task to adhere to the latest regulations and protect and maintain central heating systems long-term.”

The new measures outlined in Approved Document L of the Building Regulations are set to come into effect from 15th June 2022.
