Boiler Servicing in Purley

An annual service keeps the warranty valid and catches the small faults before they become a January breakdown. Ours takes about an hour, includes stripping and cleaning the burner where the manufacturer calls for it, and ends with a written report.

Covering about five miles from Purley, across the south London and Surrey border. Monday to Friday, 7am to 6pm. Saturday and Sunday, 8am to 5pm.

What is included

  • Flue gas analysis with the readings written down, not just glanced at
  • Burner and heat exchanger cleaned where the manufacturer specifies it
  • Gas rate and operating pressure checked against the data plate
  • Seals, electrodes and the condensate trap checked
  • All safety devices tested
  • System pressure and expansion vessel checked
  • A written report telling you what we checked and what we found

What a skipped service actually costs

A service is easy to put off because nothing appears to be wrong. This is what tends to happen when it gets skipped for a couple of years.

  • The warranty stops applying. Nearly every manufacturer requires an annual service by a Gas Safe engineer. Miss one and a two thousand pound boiler is suddenly your problem, not theirs.
  • Small faults turn into breakdowns. A weeping seal or a slowly blocking condensate trap is a ten minute job in October and a no-heat callout in January.
  • Efficiency drops. A dirty burner and a scaled heat exchanger both mean you burn more gas for the same warmth.
  • Carbon monoxide risk goes unchecked. The flue gas analysis is the part of the service that finds incomplete combustion, and nothing about it is visible from the outside.
  • You lose the paper trail. When you sell the house, a folder of annual service records is worth having and takes two minutes a year to build.

What it costs

We give you a fixed price in writing once we have seen the job. These are the things that change the number, so you know what we will be looking at.

  • A service is a fixed price per appliance. There is no separate callout charge on top of it.
  • A second appliance at the same address, a gas fire or a hob alongside the boiler, costs less than the first.
  • Booking a service and a landlord gas safety certificate together on one visit costs less than booking them separately.
  • If the service turns up a fault, we quote the repair separately and you decide. We do not fix things you did not ask for.

How it works

  1. Book a slot

    We work in morning or afternoon slots rather than eight hour windows, so you are not stuck in all day.

  2. The service

    About an hour for a standard combi. We put covers down and clean up after ourselves.

  3. The report

    You get a written record of the readings, emailed the same day, which is what the manufacturer wants to see for the warranty.

  4. Reminder next year

    We send you a reminder eleven months later. No automatic charge, no rolling contract.

After being messed around by a different company, we were recommended Go Fix and we couldn't be happier with the work they have done. Friendly, clean and they turned up everyday on time which seems hard to come by these days.

Common questions

How often should a boiler be serviced?

Once a year. Nearly every manufacturer warranty requires an annual service by a Gas Safe registered engineer, and skipping one can void it. Landlords also need an annual gas safety check, which is a different thing to a service.

What is included in a boiler service?

A flue gas analysis, a check of the gas rate and operating pressure against the data plate, cleaning the burner and heat exchanger where the manufacturer specifies it, testing every safety device, and checking the system pressure and expansion vessel. You get the readings in writing afterwards.

How long does a boiler service take?

About an hour for a standard combi. An older conventional system with a cylinder takes a bit longer. Anyone in and out in fifteen minutes has not serviced your boiler.

How much does a boiler service cost?

It is a fixed price per appliance with no separate callout charge on top, and we tell you the figure when you ring. A second appliance at the same address costs less than the first, and booking a service together with a landlord certificate is cheaper than booking the two separately.

Does a service keep my warranty valid?

Yes, provided it is done annually by a Gas Safe registered engineer and documented. We email the written report the same day so you have the evidence if you ever need to claim.

Is a boiler service the same as a gas safety certificate?

No. A service is about how well the appliance is working. A landlord gas safety certificate, the CP12, is a legal safety check on every gas appliance in a rented property. Landlords usually want both, and booking them together on one visit costs less than two separate appointments.
