Part L changes – what they mean
Since 15 June this year, changes to Part L of the Building Regulations mean we now have to carry out extra checks when installing, repairing or servicing your heating system.
Here’s an outline of the changes and what they mean for you, so you know why we’ll be talking to you more about filters, power flushes and water treatments.

What are the main Part L changes that affect heating?
Essentially, the changes are all about conserving fuel and power. And they’re aimed at keeping your central heating system working to optimum efficiency.
As your heating installer, we have already been doing most of what Part L needs us to do. But here are the main changes to look out for.
Cleaning your heating system
When installing a new boiler, including swapping your boiler for a new one, we must clean out your heating system. This usually means a power flush. At Stevenson’s, we already do this with every installation.
Adding in-line filters to your system
Part L now requires that we install a permanent in-line filter in your heating system. Again, we already fit these with every installation. And we strongly recommend one in all other cases.
Servicing in-line filters
So, now you’ll have permanent in-line filters as part of your heating system, naturally they’ll need servicing to keep them in tip-top condition. Again, we always service the filters, as part of your annual boiler service.
Protecting low temperature systems against corrosion
Another requirment of Part L is protecting your system against corrosion, scale and microbial fouling in low temperature systems.
We can protect your system with a number of different water treatment solutions and scale reducers. We can advise what suits your system best and will install the appropriate one for you.
Checking inhibitor levels each year
An inhibitor is a chemical solution that helps to stop rust and internal corrosion in your heating system. Rust and corrision affect how efficiently your heating works, so we want to prevent it!
As well as checking inhibitor levels annually, Part L now requires new inhibitor or laboratory analysis of the water every five years. We now include this as a compulsory part of your boiler service each year.
So, you can see there are a number of new requirements under Part L – but we have been doing most of them for some time. Essentially, the changes are to help your heating system work more efficiently and safely, so that’s always a good thing.
