First time turning your heating on this season? 🍂

Before the colder weather properly sets in, it’s worth doing a few quick checks to make sure everything is working as it should.

Start by checking your boiler powers up without any error messages, feel your radiators to make sure they’re heating evenly, check the pressure gauge, and have a look around radiators, valves and pipework for any signs of leaks.

If your radiators are cold in places, your boiler pressure doesn’t look right, or something just doesn’t seem quite right, it’s best to get it checked sooner rather than later.

Need a hand getting your heating ready for the colder months? Give our team a call on 01442 971 775.

Cold radiators? It could be more than just trapped air.

Over time, sludge, rust and debris can build up in your central heating system, stopping hot water from circulating properly and leaving your radiators cold or patchy.

Our latest blog explains what causes cold radiators, when power flushing can help, and why it’s worth getting your heating system checked before the colder months properly set in.

Head over to our website to read the full blog.

Recent boiler install completed ✅ Swipe above to see the work in progress.

A new boiler is always a big upgrade, but we know the little things matter too — like leaving your home exactly as we found it.

With every install, our team works cleanly and carefully, making sure everything is tidied, cleared away and put back in place before we leave.

Safe install, smart finish and no mess left behind. That’s how it should be.
