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!

Boiler Servicing

Your Boiler works hard year-round, especially during winter. Dust builds up, seals and parts wear, and gas consumption increases. You end up paying more while getting less heat.

A yearly Boiler Service keeps everything running as it should:

Servicing keeps your Boiler clean. Keeping your fuel bills lower.

Servicing also keeps your warranty active. This saves you money if a part ever fails.

Most importantly, regular servicing keeps your family safe. The engineer checks for silent issues, including carbon monoxide. A deadly gas you can’t see or smell.

So what does a full-service actually include?

What’s Included in a Boiler Service?

A Boiler service is more than a quick look.

Your engineer follows a step-by-step set of checks designed to keep your Boiler clean, safe, and running well.

Your Service Includes:

Gas pressure & airflow checks

We measure your Boiler’s gas pressure and airflow to ensure it burns fuel at optimal levels. Delivering steady, reliable heat throughout your home.

Full check of seals, flues, & safety devices

All seals, flue joints, and safety components are inspected. Ensuring they’re secure and safely venting gases outdoors.

Cleaning of internal parts

Internal components are cleaned to remove buildup, which causes noise, wear, and reduced performance.

Tests for gas leaks & carbon monoxide

We test for any signs of gas or carbon-monoxide leaks. To keep your family and home safe.

Thermostat & control checks

Your thermostat, timers, and heating controls are checked for accuracy. Ensuring your system responds exactly as intended.

Adjustments to increase efficiency

We make adjustments which boost your Boiler’s efficiency. Helping to reduce your energy bills.

A written service record for your warranty

You’ll receive a full-service report, providing documented proof of maintenance for your Boiler’s warranty and for future reference.

Beyond safety, there’s another benefit…

How Servicing Saves You Money

Boiler failures don’t usually happen overnight. They start as tiny problems. A loose seal, trapped air, and a worn heat reader.

These small issues cause wasted gas and rising bills long before the Boiler stops working.

Regular Boiler Servicing prevents these hidden issues from becoming essential repairs. A service today costs far less than a major repair tomorrow.

A clean serviced Boiler burns fuel more efficiently. It costs less to run.

Boiler Repairs

If your Boiler stops, you can’t wait days. You need your heat back. You need your hot water back. Quickly.

Our Boiler Repairs in Sutton give you a fast, same-day response. With repairs carried out by Gas Safe engineers. With no call-out charges.

We fix the majority of problems in a single visit. We carry various replacement Boiler parts.

We’ll find the exact problem. We’ll ensure you get a lasting repair, not a short-term fix.

Common Boiler Problems We Fix

Our engineers repair every make and model of Boiler.

We’ve seen and fixed every common boiler issue, including:

No heating or no hot water

Failed components—typically the diverter valve, pump, or thermostat. Stop hot water from circulating through the system.

Leaks

Worn seals, corroded pipes, or faulty internal components cause leaks. Allowing water to escape from the boiler or system joints.

Pressure loss

Pressure drops because of a leak, a faulty pressure-relief valve, or trapped air.

Radiators staying cold

Trapped air, sludge buildup, or a failing pump prevent hot water from circulating through the radiators.

Whistling, banging, or gurgling noises

Trapped air, limescale buildup, or restricted water flow inside the system creates whistling, banging, or gurgling noises.

Ignition or pilot light problems

Faulty electrodes, blocked burners, or gas-supply issues stop the Boiler from igniting.

Faulty thermocouples

A broken thermocouple shuts down the gas-safety mechanism and stops the Boiler from lighting.

Faulty thermostats

A malfunctioning thermostat sends incorrect temperature signals, preventing your Boiler from heating your home properly.

Whatever the problem, we’ll find the cause and restore your heating in full compliance with safety standards.

Warning Signs You Should Never Ignore

Boilers give clues before they stop working.

These early signs tell you something isn’t right:

  • Gas bills are rising for no clear reason
  • Noises or shaking
  • Repeated resets
  • Damp patches or rust near the Boiler
  • Repeated pressure loss
  • Water is not heating properly

If you notice any of these issues, book a quick visit.

A small fix now will prevent the stress of a full Boiler failure later.

Support for Homeowners & Landlords

If you’re a landlord, you need safe gas appliances and clear records.

We can handle your yearly Boiler Service, your safety certificates, and any repairs your tenants need, all in one visit.

We can also be on hand for Boiler breakdowns.
