What is an annual boiler service?

Boiler Service

To put it simply, a boiler service is some tests, checks, and clean-ups performed on your boiler by a Gas-Safe qualified boiler engineer. 

This is to make sure that your boiler is running efficiently and correctly, as well as finding potential problems your boiler may have, that are better to be addressed sooner rather than later.

What does boiler service include?

A Gas Safe registered engineer will have a checklist of certain things to check during the service, this will include all the correct steps they will need to take to complete your boiler service.

 For your service certificate to be checked off as completed,  below are some measures the engineer will usually take within a boiler service.

Visual Inspection

An engineer usually begins by overseeing the whole system and looking out for any signs of damage, faults, or corrosion on the boiler. 

With their expertise, they will be able to see if any problems need addressing visually.

boiler casing removal

Once the Gas Safe engineer has completed the visual check, they will then remove the casing from the boiler, to perform a more in-depth check of the boiler’s insides.

 This will include things like the burner, heat exchanger, and other elements in terms of importance when it comes to the boiler’s performance.

Flue check

The engineer will check your flue as well, this is to make sure that it is fitted properly and no blockages are occurring within it.

Pressure checks

Your gas pressure will also be checked, this will make sure that your radiators and taps will be powered and heated to the right level.

Additional checks

The engineer will then complete some additional checks, these will include pipework, boiler parts, and controls as well as safety devices checked to make sure they are in working order.

What is not included in a boiler service?

Some things are not included as part of your routine annual boiler service. 

For example tasks such as bleeding radiators, pipe unblocking, or even a deep clean of your central heating system.

Regular boiler service does not mean the engineer will necessarily fix any problems with the boiler in the service but rather address any issues that may be apparent. If you have a boiler cover, breakdowns may be included, but it’s important to see if they are included in your policy.

Who is required to complete a boiler service?

Only a Gas Safe registered engineer can complete a boiler service. This is because they are fully qualified,  and have expertise in the field, along with the correct training and skills to complete your service to a safe and satisfactory standard. 

Gas Safe engineer

The Gas Safe registered engineer will then give you a boiler service report containing details and confirmation of all of the checks they have completed throughout the service.

 Attempting to service your boiler can not just be highly dangerous, but also is illegal to try and complete a gas boiler service without the necessary qualifications as per the Gas Safety Regulations (1998).

How do I know if I need a boiler service?

Lack of Servicing

If you have had your boiler for many years, and have not yet had a service you are certainly due one. 

This will give you peace of mind for preparing your boiler for the winter dawning ahead, to avoid your boiler breaking in the future in the cold weather. If your boiler is older and hasn’t been serviced for a few years it can pose some more serious risks of a boiler not serviced down the line, and keeping your boiler in tip-top condition.

Leaking Boiler

If you are experiencing your boiler leaking water could be a serious sign that a more serious problem is approaching, so it is important to get a service booked so the heating engineer can address any issues so you can take action as soon as possible.

 Efficiency Problems 

If your boiler isn’t operating as efficiently as it was when it was first purchased, it’s vital to get it addressed. With energy costs rising in the UK, any problem related to energy efficiency should be rectified.

Pros and cons of boiler servicing

How often should you get boiler service?

Many people are aware they need to get their boiler serviced, but if you find yourself asking “How often do I need to have my boiler serviced?” Well, It is recommended to get a boiler service at least once a year. 

An annual boiler service helps avoid any risks or problems arising with the boiler and will also make sure your boiler performs to the best standard it can, as well as giving you a piece of mind that your boiler is running smoothly, and to a safe standard.

Boiler service to maintain warranty

All new boilers come with a warranty given by the manufacturer, this can save you a lot of money down the line in breakdown repairs, the only thing the manufacturers require you to do to maintain this warranty is get a yearly boiler service.

If you find yourself wondering,” Is my boiler still under warranty?” You can check by getting in contact with the manufacturers, who usually have warranty checkers and helpful customer service teams.

How long does a gas boiler service take?

How long does it take to service a boiler? Well, depending on what boiler you have, a normal boiler service will usually take about half an hour to complete. Well, that is the case for combi boilers; regular boilers can usually take longer stretching to an hour and a half to check all components.

 Similarly, system boilers will take usually around an hour, this is mainly due to the separate hot water tank being in a different location, which usually takes up more time.

What is a boiler service plan?

 Boiler service plans are an option that lets you spread the cost of your annual boiler service, monthly. It is useful as it means you don’t have to pay a large amount up front, at the time. 

Some service plans also come with annual reminders, so you don’t forget to book your service and invalidate the manufacturer’s warranty.

A service plan differs from a boiler cover/ boiler insurance plan, as it just covers your annual service. If you want a greater layer of protection for your boiler, then a cover plan might be the better option to choose.

 Cover plans usually cover parts, labour, and depending on which plan you get even your radiators, pipework, and more,  however, boiler cover plans usually have a greater cost per month. It’s also important to check that an annual boiler service is included in any boiler cover packages you decide to look at.

Boiler service cost

The normal cost of a boiler service will fall between £80 to £120, although this usually depends on boiler type, location, and service provider.
