Contacted ADheat for assistance in finding a fault with our Vailant boiler. From the first dealing I had with them, they were absolutely superb. Very professional and courteous from the outset. They fully explained their charges in advance of booking the appointment, which is brilliant, as it avoids any unexpected surprises later on! Our engineer was great. Very informative and explained exactly what he was doing and why it was needed. Found the fault within the first hour, and then rectified it quickly and efficiently. All in all, took just under 2 hours and no parts needed. Would 100% recommend them, and will certainly be using them again for other work in the future.

We found ADheat to be a thorough competent, and professional plumbing company. The ease at which they were able to deal with our matter in hand. Sent pictures to our contact via Whatsapp, and received quote the same day. We didn't have to wait weeks on end, as he had his extensive team of plumbers to undertake work as soon as quote excepted. Work completed within half a day, and a few days after the work done, we received the invoice, which we duly paid the following day. Very happy with the finished work, and would like to thank Alfie, and Josh for their service.

Had a conventional heating system replaced with a combi boiler and must say I am incredibly satisfied with every stage of the process.

You can tell this company takes pride in their craft by how hard and neat they work as well as by how they take their customer's wishes into consideration.

Thanks!

Why Your Sutton Property Needs an Annual Gas Safety Inspection

Landlords across Sutton are tightening their gas safety checks. And for good reason.

One missed inspection can trigger a chain of problems you never see coming.

Tenant complaints, safety risks, insurance problems, and council attention, which can end in fines…

One Inspection Prevents All of This

A quick, scheduled gas safety inspection keeps:

Your insurance valid
Your tenants protected
Your property protected
You are the landlord on the right side of the law

Landlords must have a Gas Safety Inspection and issue a valid CP12 certificate to their tenants every 12 months.

And it’s not just landlords. Homeowners benefit from gas safety inspections, too.

Sutton homes vary. Some are older and have been converted. Others are newly built.

Gas systems age at different rates, and many homeowners don’t bother with gas safety inspections.

Hidden faults often go unnoticed until they become dangerous. A periodic inspection ensures your gas system is safe.

So what exactly happens during the inspection?

What Your Gas Safety Inspection Includes

During your appointment, a Gas Safe engineer arrives at a time which works for you or your tenants and checks every part of your gas system to confirm it’s safe.

Your inspection covers:

Boiler performance and safety tests
Full appliance testing
Flue and air-flow checks
Gas pressure testing
Leak detection
A quick review of the overall system performance

In short, everything needed to confirm your property’s gas system is safe to live in. Legal to let.

Once the checks are complete…

Your CP12 Certificate

After your Gas Safety Inspection, you receive your CP12 certificate. It lists every test performed and any issues found.

You must give tenants a copy within 28 days, and new tenants need it before moving in.

Keep your copy for at least two years. Insurance providers and letting agents frequently request it. Your CP12 is proof your property is safe and compliant.

But what if something doesn’t pass?

If Something Fails the Inspection

If an appliance or part of the system doesn’t pass, the engineer will provide a clear explanation of the issue and a fixed-price repair quote.

If something is unsafe, it’s switched off immediately. Once the repairs are complete, we can issue your new CP12 certificate.

Here’s why Sutton landlords use us for gas safety inspections…
