    How does a boiler service work?

    When Does A New Boiler Need Service For The First Time?

    Despite what you think, a new boiler does require servicing. Boiler service is a must to keep your boiler fit and working efficiently. In short, to keep your new boiler running smoothly for years on end, a regular boiler service is the way to go.

    A boiler requires servicing a year after installation. It is recommended that you would service your boiler yearly to keep it working efficiently.

    Servicing a boiler does not just involve fixing issues that your new boiler might have, but it’s about detecting symptoms for upcoming problems. Minor issues, if left unfixed, can lead to serious complications and costly repairs. It goes without saying that fixing a problem before it escalates is much safer than waiting until it is too hard and costly to fix.

    Your boiler performance in general is bound to drop in time and lose some of its old efficiency. However, with regular maintenance and servicing, this ageing process will be delayed and you will be able to extend the lifespan of your boiler for years to come.

    Generally speaking, most boilers have a standard warranty of 5 years. However, some boiler brands do have longer warranty periods. If you want your boiler warranty to stay valid, then regular service is required. In other words, your warranty will be valid when your boiler is serviced on a regular basis.

    Why do I need to service my boiler?

    To prevent Carbon monoxide poisoning

    Carbon Monoxide is an odourless gas. It can result from a leak within a gas appliance. It can only be detected by alarms. And it can be fatal if you’re exposed to it for too long.

    To maintain a high level of efficiency

    A boiler maintained poorly could cost you more in utility bills. A regular serviced boiler is cheaper to run and will save you money on energy bills.

    To keep your boiler warranty valid

    Most manufacturers’ warranties require that your boiler should be maintained by means of regular servicing to keep your warranty valid.

    That is why boiler service is essential to your heating system. By no means should you delay boiler service or put it off.

    What is involved in a boiler service?

    You might be wondering what a boiler service includes. Well, we have prepared a guide to explain what is involved in the process.

    Visual inspection

    The first stage that takes place in a boiler service is the visual inspection. Your engineer will visually check your boiler from the outside. Engineers are qualified to inspect the safety and efficiency of your boiler. They will check for the parts that are working safely and the parts that don’t look like they are.

    The engineer will be looking for any leaks or corrosive damage that may have taken place since their last inspection. The boiler flame will also be checked to see if it looks normal.

    Removal of Casing

    After the completion of the visual inspection by the Gas Safe Registered engineer, they’ll then look at the interior parts of your boiler. This procedure requires the removal of the boiler’s casing. This casing protects all the main components within the boiler from damage and is where the engineer will check the components and clean the inside of your boiler where it is necessary. The things that will be checked are: the burner, the heat exchanger, and other components which are essential for the performance of the boiler.


    A boiler service includes several other checks These checks include the following:

    Gas pressure check

    A gas pressure check is important due to the fact that a high or low boiler pressure can lead to problems and affect your boiler’s performance and lifespan as well. Your taps and radiators won’t function properly if the gas pressure isn’t at the correct level.

    Flue check

    To check for obstruction within the flue terminals, the heating engineer will be required to perform the flue check. What is more, a flue analyser will be used to check for flue emissions. This is to confirm that the flue is burning safely with readings within the tolerances set in correspondence with the Boiler manufacturer instructions. This process will help discharge any dangerous emissions. Now, it must be said that a Gas Safe engineer is required to carry out these checks.

    Checking that the boiler fires properly

    The engineer will check that the boiler starts up as it should and that there are no faults with your boiler whatsoever.

    After the completion of the checks, a report of the condition of your boiler, including any problems or issues that your boiler has. They will also include what is required to fix these issues.

    When to tell if your boiler needs servicing

    There are some signs that can help you know if your boiler requires servicing.

    The pilot light is off

    The pilot light is like the ignition of your boiler, so it is a key function of the appliance. Pilot lights are usually featured with old boilers. However, some new boilers can have them. A pilot light that is turned off or that keeps turning off can be an evident sign of boiler trouble. The pilot light is like the ignition of your boiler, so it is a key function of the appliance.

    A yellow light can indicate carbon dioxide leaking.

    unusual noises

    The strange noise that you hear from your boiler as the heating turns on isn’t a problem. However, if your boiler is making a noise that you have not heard before or not familiar with, this might indicate that your boiler needs servicing. Strange bangs and sounds could mean the wear and tear that sometimes a boiler encounters as it gets older over time.

    The last service was over a year

    A year is relatively a long time for a boiler. Some issues with your boiler might occur in just a year. That is why routine checks are critical in maintaining that your boiler is working efficiently. Not to mention that you risk your warranty being void if you don’t get your boiler serviced.

    unusual odour

    Smelling unusual odours are a sign that the gas in your boiler might be leaking or may have some issues. Dark markers around the casing of the boiler might be noticed. These markers can be a sign that your boiler is leaking. Although carbon monoxide is odourless, there will be some unusual odour coming from your boiler in case of a leak.

    Inefficient performance

    You can check the performance of your boiler by checking if your hot water taps are delivering hot water quickly. You can also see if the radiators are hot or tepid. When your boiler isn’t working properly, then it’s going to work inefficiently.

    How long does a boiler service take?

    A boiler service does not take too long to complete at all! Typically, it can take between 30 minutes or an hour to ensure that the boiler is in good working condition. However, if your boiler might need more time, your engineer will inform you of that fact. You will be provided with a Gas Safety Certificate as proof that the annual service has been made.

    How much does it cost to service a boiler?

    A boiler service cost will depend on the engineer providing the service. This could range anywhere between £60-£150, with the average being £75. You can either choose to pay the one-off fee for the annual boiler service or pay for a boiler cover plan to keep you covered throughout the year.

    What happens if I don’t service my boiler?

    Without boiler service, you will shorten the lifespan of your boiler and cause its early death. An unchecked boiler can be life threatening to you and your family. What is more, your boiler will be less efficient, consume more energy and increase the risk of constant breakdown.

    Can any plumber do a boiler service?

    Not all plumbers are qualified to work with boilers. For any work on your boiler system, you will need to employ a Gas Safe registered heating engineer to do the work.

    Does boiler service include cleaning?

    During a boiler service, the engineer will remove, inspect and clean the main components in the boiler to make sure they are fit for purpose and have no noticeable defects.

    Can I service my own boiler?

    Any boiler maintenance and troubleshooting need the right equipment and training. So it’s important to seek professional help in the case of any serious problems or any regular check.

    What does installing a new boiler involve?

    If you are renovating, then you don’t have to dig up your floors to install underfloor heating.

    How long does underfloor heating take to warm up?

    An underfloor heating system that is fitted on top of your floors heat up very quickly, whereas a system which is set within a screed might take longer to heat up your home. However, it can retain heat for a longer time and you can also programme it to provide the right amount of required heat.

    Is underfloor heating safe and good for your health?

    Well, underfloor heating is, without a doubt, healthier and safer than radiators since exposed hot surfaces are hidden and dust traps removed. They are a controlled and comfortable heat source, which can help in eliminating draughts and cold spots around your home.
