What our boiler service covers

A service is not just a quick look and a sticker. We work through the boiler properly and leave you knowing exactly what condition it is in.

  • Visual inspection of the boiler, seals and casing
  • Gas rate and operating pressure checked against the manufacturer's figures
  • Flue and combustion analysis to confirm it is burning safely
  • Key components inspected and cleaned as needed
  • Controls, thermostat and safety devices tested
  • System pressure checked and topped up if required
  • Full function test before we leave
  • A clear explanation of anything we found

Why an annual service is worth it

A serviced boiler burns less gas for the same amount of heat, so it costs less to run. It is also far less likely to fail when you need it most, because worn parts get spotted while they are still cheap to replace.

Just as importantly, a service confirms the boiler is burning safely and venting properly. That is the check that protects your household from carbon monoxide, and it is not something you can do yourself.

Landlords and rental properties

If you let a property, you are legally required to have an annual gas safety check on every gas appliance and flue. That is a different job from a service, though we are happy to do both in one visit.

See our gas safety certificates page for what the check involves and what you receive afterwards.

Questions

Frequently Asked Questions

How often should my boiler be serviced?

Once a year. An annual service keeps the boiler running safely and efficiently, and most manufacturer warranties require it in order to stay valid.

How long does a boiler service take?

Allow around an hour for a standard domestic boiler. If we find a fault that needs attention we will explain it and give you a price before doing any extra work.

What is included in the service?

A full safety inspection, gas pressure and flue gas checks, inspection and cleaning of key components, a check of the seals and controls, and a test of the system once it is back together.

Do I need a service if the boiler seems fine?

Yes. A service catches wear and small faults before they become breakdowns, confirms the boiler is burning safely, and protects your warranty. Carbon monoxide risks are not always something you would notice yourself.

Can you service my boiler and issue a landlord certificate at the same visit?

We can. A gas safety check and a boiler service are separate jobs, but doing them on the same visit is usually more convenient — just mention it when you book.
