Boiler servicing.

Why should you get your boiler serviced?

No-one wants to be left in the cold, and by organising an annual service of your boiler you reduce the risk of it breaking down. As your boiler gets older it’s more likely to develop issues which is why a regular boiler service can keep it running for longer.

As well as improving your boiler’s lifespan, you’ll also need to have your boiler serviced annually to keep your manufacturer’s guarantee. If your boiler breaks down during the manufacturer’s guarantee period, and you can’t prove it’s been serviced by a Gas Safe engineer in the last twelve months, then you’ll be liable for the repairs.

What happens during a boiler service?

A Gas Safe engineer will conduct various checks to ensure your boiler is functioning effectively and efficiently. The boiler service checklist includes:

  • A visual inspection of your boiler, its controls and flues to check for any signs of damage or distress.

  • Inspect the controls and safety devices so it operates correctly.

  • Inspect the construction termination and route of the flue and that there are no obstructions.

  • Clean the main boiler components such as the main burner, heat exchanger, flue and ignition pins.

  • Check polarity and voltage readings.

  • Gas and pressure flow.

  • Record the boiler pressure or heat input.

Once the boiler inspection is complete, the engineer will give you a post-service report. Make sure to keep it in a safe place as you’ll need it to keep your boiler’s warranty valid.

If your boiler needs a small fix then the engineer will normally try to fix it there and then. If it’s a bigger issue or parts are needed then you’ll probably need to schedule another appointment to get your boiler fixed.

How much does the boiler service plan cost?

The boiler service plan costs £396, which covers your new boiler for three years. You can either choose to make this as a one-off payment when you buy your new boiler or add it on to your boiler finance package.

How long does a boiler service take?

A boiler service will normally take around an hour, however if repairs are needed then it can take longer.

When will the annual boiler service take place?

The first boiler inspection will normally take place between April and September. The next annual service will take place on or close to this date the following year.

This may mean that your first service is a little more than a year after the boiler was installed, but this is still covered by the guarantee.

Are boiler services worth it?

Boiler servicing is another home expense, however it could help you save money in the long run. As part of the inspection, our Gas Safe professional will help to make your boiler run more efficiently, which means it’ll cost less to have your heating and hot water in use.

Regular boiler

Regular boilers.

If you often use hot water in multiple places at the same time, consider a regular or condensing boiler, linked to a hot water cylinder and a cold water storage tank.

System boiler

System boilers.

Designed for homes with more than one bathroom, system boilers give you a constant supply of hot water to multiple taps. There’s no need for the tank in the loft either.
