Boiler Servicing & Repairs You Can Trust

Keep your boiler safe, efficient – professional boiler repairs and servicing in Greater London and the South-East

BOILER SERVICING & REPAIRS

A faulty boiler can be more than just inconvenient – it can leave you without heating or hot water when you need it most. At Harvard Heating, we provide fast, reliable boiler repairs and thorough annual servicing to keep your system in top condition all year round.

WHY CHOOSE HARVARD HEATING?

If your boiler has broken down or is making strange noises, leaking, or losing pressure, don’t panic. Our Gas Safe Registered engineers will come out quickly to diagnose the issue and get things working again. We carry out repairs on most major boiler brands and aim to resolve the problem on our first visit wherever possible.

We understand how stressful it can be when the heating stops – that’s why we’re committed to clear communication, fair pricing, and friendly service from start to finish.

ROUTINE BOILER SERVICING

Regular boiler servicing keeps your system running safely and efficiently, helping to prevent costly breakdowns and maintain your warranty. We recommend servicing your boiler once a year, ideally in late summer or early autumn, so it’s ready to handle the colder months ahead.

During a service, we’ll carry out a full inspection, clean internal components, and check for any signs of wear or faults — giving you peace of mind that everything is working as it should.

WHAT ARE THE BENEFITS OF BOILER SERVICING?

IMPROVES ENERGY EFFICIENCY

A regularly serviced boiler runs more efficiently, using less energy to heat your home — which can lower your energy bills and reduce waste.

KEEPS MANUFACTURER’S WARRANTY VALID

Most boiler warranties require an annual service by a qualified engineer. Skipping it could void your warranty and leave you unprotected if something goes wrong.

ENSURES YOUR BOILER IS SAFE

Servicing includes crucial safety checks, such as detecting gas or carbon monoxide leaks, ensuring your boiler is legally compliant and safe for your household.
