Boiler Service

Your Boiler Needs a Service

Just like a car or other complex household appliances, regular boiler service is essential to extend the life of your boiler and keep it running efficiently. It’s also a requirement of the guarantee. You should have your boiler serviced each year by a Gas Safe-registered, qualified and approved engineer.

Servicing your boiler will help to make sure it stays safe and uses fuel efficiently. There are clear regulations and standards for testing and servicing a boiler. The manufacturer’s manual will set out the procedures the engineer should follow for your boiler service.

Your Time Switch is Faulty

Time switches turn the boiler on or off at the times you set. If the time switch fails, the boiler may not work. There are various types of time switch available, from simple mechanical dials to sophisticated digital multi-function controls.

Your installer will be able to tell you how to fix the time switch or advise you about a replacement.

Your Printed Circuit Board is Faulty

PCB is short for Printed Circuit Board. Modern boilers run electronically and the PCB is the ‘brain’ of the boiler. If there is a problem with the PCB it may lead to the boiler working incorrectly or not at all. Like all electronic parts, PCBs are complex electronic devices that occasionally become damaged or stop working properly.

But the PCB isn’t always at fault and a good installer will check the rest of the boiler and system before automatically changing the PCB. If the PCB is faulty, the installer should replace it with a new part from the original manufacturer.

Your Pilot Light Has Gone out or Isn’t Working Correctly

A pilot light is a small constant gas flame that ignites your boiler to provide you with heat or hot water. Pilot lights are only found in old boilers. If the pilot light is not working properly, the boiler will not work. Pilot lights are not found in modern high-efficiency boilers, as more efficient and reliable ignition systems are available.

Pilot lights can go out for a variety of reasons. Sometimes it’s as simple as a strong wind or draught blowing the flame out or a build-up of deposits on the nozzle. But your installer will need to investigate the cause. A boiler with a pilot light is likely to be an older model, inefficient by modern standards – it may be time to consider replacing it.

Boiler Service with Gas Safe-Registered Engineer

The Gas Safe Register is the official list of gas engineers who are qualified to work safely and legally on gas appliances. The Gas Safe Register is the official gas registration body for the United Kingdom, Isle of Man and Guernsey, appointed by the relevant health and safety authority for each area.

By law, all gas engineers must be on the Gas Safe Register. Gas Safe Register has replaced CORGI as the gas registration body. For more information visit
