Boiler servicing

Annual boiler servicing for homes and rental properties

A yearly visit that keeps your boiler safe, running efficiently and protected by its manufacturer's warranty, whether you live in the house or let it out.

What a boiler service is

A boiler service is a planned inspection by a qualified engineer, done while the boiler is still working rather than after it has failed. It's the moment to catch small issues, such as a worn seal or a component starting to struggle, before they turn into a cold house on a January morning.

A worthwhile service goes well beyond confirming that the boiler lights. We look at whether it is operating safely, whether it is burning fuel efficiently and whether any parts are showing early signs of wear. If you're unsure how this differs from a wider system check, our guide to boiler service vs heating service explains the distinction.

When a service is due

For most homes the answer is once every twelve months, but a few situations make booking particularly worthwhile.

  • It has been about a year since the last visit.
  • Autumn is approaching and you want the boiler checked before it works hardest.
  • Your manufacturer's warranty asks for yearly servicing as a condition of cover.
  • You've just moved in and have no idea when the boiler was last looked at.

What happens on the day

We start by asking whether you've noticed anything odd, such as noises, pressure changes or slow hot water, because those clues tell us where to look hardest. Then we work through the boiler's safety, checking that it runs and vents as it should, followed by its efficiency, so you're not paying for fuel that's being wasted.

Finally we look for early wear on the parts most likely to cause a breakdown later. Before leaving we explain what we found in plain terms, including anything worth keeping an eye on. For a fuller walk-through, read our boiler service guide.

Gas, LPG and oil boilers

We service gas, LPG and oil boilers. Gas appliances are worked on by our Gas Safe registered engineers, and LPG and oil boilers by qualified engineers, so rural properties without mains gas are covered too. Our article on choosing a Gas Safe engineer explains what to check before anyone works on your boiler.

Landlords and letting agents

Alongside private homes we look after rental properties, covering the yearly service and reactive repairs if something goes wrong between visits. Landlords and letting agents can book directly with us, and having one local firm that already knows the boiler makes the next call-out simpler for everyone.

If the service finds a fault

Sometimes a service turns up a part that needs replacing. When that happens we tell you what's wrong and give you a clear price before doing anything further; there is no obligation to go ahead there and then. Our boiler repair page explains how we deal with faults. If the boiler is near the end of its life we'll say so honestly, and our boiler installation page covers the next step. Where radiators have cold patches caused by sludge, a powerflush may be worth considering.

Frequently asked questions

What does a boiler service actually check?
It covers three things: that the boiler is operating safely, that it is running efficiently, and whether any parts are beginning to wear. It is a proper inspection rather than a quick check that the boiler turns on.
Will skipping a service affect my boiler warranty?
It can. Missing services may invalidate a manufacturer's warranty, so booking one every year is the simplest way to keep that protection.
How often should my boiler be serviced?
Once a year. Many people like to book ahead of the colder months, when the boiler is about to do its heaviest work.
Do you service boilers in rental properties?
Yes. We work for landlords and letting agents as well as homeowners, handling annual servicing and reactive repairs.
Can you service LPG and oil boilers?
We can. Qualified engineers look after LPG and oil boilers, and gas boilers are serviced by our Gas Safe registered engineers.
What happens if the service finds a problem?
We explain the issue and give you a clear price for fixing it. Nothing further is done until you've decided you want to go ahead.
