Gas Boiler Service, What’s Involved?

You need to get your gas boiler checked on and serviced every year, regardless of whether it’s working well or not. Find out why boiler services are critical and what to expect from our engineers.

It’s easy to think of gas boiler servicing as a wast of money, as many things are now cheaper to replace than repair but that’s not true of your gas boiler. It’s something you use every day even during to the summer months. And this constant use does wear out aspects of the boiler.

An annual service is essential for a boiler to continue to work at its maximum efficiency. And a gas boiler operating inefficiently costs you money.

Plus the cost of replacing a boiler can run you up to £4,000 which will make a severe dent in anyone’s holiday plans.

But, far more importantly, not maintaining you gas boiler might be dangerous to you and your family.


Why Do I Need Get My Boiler Serviced?

Taking care of your gas boiler is important for a number of reasons including energy efficiency and it’s long life, but it’s most important to identify any small problems that may lead to catastrophe.

Gas Service For Safety 

When it comes to your family and loved ones, it has to be safety first. A gas boiler service involves a range of different checks to make sure that the boiler is operating correctly and has no underlying issue. A faulty gas boiler can lead to carbon monoxide leaks. This colourless and odourless gas can have extremely negative effects on one’s health and is difficult to detect.

A carbon monoxide detector should be kept close to the boiler to warn of any dangers.

Boiler Servicing To Keep Heating Bills Low

As a boiler gets older, it begins to work less efficiently. This ageing process can be mitigated by regular servicing during which the boiler is cleaned and any faulty parts can be replaced. A more efficient boiler means cheaper energy bills for you.

Gas Boiler Repairs & Boiler Warranty

Boiler manufacturers require you to have your gas boiler serviced annually by a qualified RGII engineer and should you miss a year, you will void your warranty and any parts or subsequent repair work needed, you’ll have to foot the bill.

Signs That Your Boiler Needs An Immediate Inspection Boiler Expert

Whilst an annual gas boiler service will  ensure your peace of mind, in the unlikely event of an issue arising between boiler services, you should be aware of some of the signs of trouble.

A yellow pilot light indicates that there is an issue with the combustion chamber and means that a carbon monoxide leak is likely. Carbon monoxide is a colourless and odourless gas that can prove fatal.

In the event of yellow pilot light, you should turn off the gas boiler and contact an RGII registered heating technician immediately.

All gas boilers are white so that any appearance of soot or smoke damage is clearly visible. Should you see smoke damage or soot on or near your boiler, you should contact your RGII registered technician right away. This is another sign of a carbon monoxide leak.

Irregular noises coming from a boiler can indicate a number of different problems. If your boiler is making strange noises, schedule a gas boiler service at the next opportunity.

Whist carbon monoxide has no odour, a strange smell coming from your boiler when it’s running does indicate a serious problem with the combustion chamber and probably an accompanying leak. You should contact an RGII registered technician at the earliest opportunity.


What Does a Gas Boiler Service Involve?

Gas boilers must be serviced by a Gas Safe registered engineer which means they are on the official list of people legally authorised and qualified to work with gas appliances. The engineer will assess the safety, reliability and efficiency of the boiler including:

Only heating engineers who are registered with the RGII are authorised to cary out the necessary checks on a gas appliance. The registered engineer has a detailed series of steps that must be worked through before your gas boiler can be declared serviced. These include;

  1. A visual review of the boiler itself for the correct colour pilot light, signs of corrosion, soot, or smoke.
  2. An inspection of the internal parts including the burner, spark probe and the heat exchanger.
  3. The engineer will check the flue terminals are safely installed and there are no obstructions and a review of the seals and pipework.
  4. A readings take is also need to make sure the gas pressure is at a safe level.
  5. And lastly, the boiler must be started to ensure that everything starts in the correct order and the temperature controls are error free.

After the service is finished, you get a full report of all the completed checks to confirm that everything is working as it should. A complete gas boiler service should take no longer than 30 mins unless there are parts to be replaced or other issues.
