Boiler Servicing

A routine annual service keeps your gas boiler running reliably and helps identify small issues before they become bigger problems. We carry out a thorough inspection and maintenance visit at a time that suits you.

Boiler Repairs

Loss of heating, pressure problems, unusual noises or inconsistent performance — we diagnose common boiler faults and carry out the repairs needed to get your heating working again.

Heating Controls

Upgrading from an older programmer or thermostat gives you more control over when and where your home is heated. We install and replace heating programmers, thermostats and smart heating controls.

Radiator Repairs

Cold spots, leaks, uneven heat or noise from a radiator usually point to a fixable issue. We troubleshoot the cause and carry out the necessary repairs, including radiator valve replacement where needed.

Power Flushing

Sludge and debris build up inside central heating systems over time, reducing circulation and affecting how well radiators heat. A power flush cleans the system and can help restore more even heating throughout the home.

Hot Water Cylinders

We repair and replace domestic hot water cylinders, and can advise on the right capacity and compatibility with your existing system — whether you need a straightforward repair or a full replacement.

FAQs

Common Questions About Our Heating Services

Answers to the questions we're asked most often — covering boiler servicing, repairs, controls and more.

How often should a gas boiler be serviced?

Most boiler manufacturers recommend an annual service. Servicing your boiler once a year helps keep it running reliably and allows a heating engineer to spot any developing issues before they lead to a breakdown.

My boiler is losing pressure. Do I need a repair?

Pressure loss can have a few different causes — a small leak, a faulty component, or the system needing a re-pressurise. It's worth having it looked at to identify the cause, as some issues can worsen over time if left.

Some of my radiators are cold at the top or bottom. What's causing it?

Cold spots at the top of a radiator usually suggest trapped air, which can often be resolved by bleeding the radiator. Cold spots lower down or across the whole radiator may point to sludge buildup or a circulation issue. We can diagnose the cause and advise on the right fix.

What is power flushing and when is it recommended?

Power flushing is a process that cleans sludge, rust and debris from inside a central heating system. It's often recommended when multiple radiators are heating poorly, when a new boiler is being installed into an older system, or when circulation appears restricted. It can help restore more even heating throughout the home.

Can you replace my older heating programmer or thermostat?

Yes. We install and replace heating programmers, thermostats and smart heating controls. Upgrading from an older controller can give you more flexibility over when your heating and hot water come on, and how different areas of the home are managed.
