A boiler is an integral part of any home, providing hot water and central heating. Like any other appliance, it requires regular maintenance to ensure its efficiency and longevity. However, one question that often arises is: how much should a boiler service cost in 2023? This blog post aims to provide insights into the costs associated with boiler service and repairs.


Understanding Boiler Service Cost

Boiler service cost can vary widely depending on various factors such as the type of boiler, its age, location, and the specific issues it may have. However, on average, a standard boiler service cost ranges anywhere from £60 to £150 in the UK.

This price typically includes a thorough inspection of your boiler and controls to ensure they are operating safely. The engineer will also clean parts as required and identify any wear or faults.

It’s important to note that these estimated prices are for servicing only. If your boiler requires repairs or replacement parts, these will be additional costs.

Factors Influencing Boiler Service Cost

1. Type of Boiler: The type of boiler you have can significantly impact the cost of servicing. For instance, oil boilers tend to be quite a bit more expensive to service than gas boilers due to their complexity.

2. Age and Condition: Older boilers or those that haven’t been serviced regularly may require more work during a service check-up which could increase the cost.

3. Location: Where you live can also affect the price you pay for a boiler service. Prices tend to be higher in cities and southern regions due to higher living costs.

4. Engineer Rates: Different engineers charge different rates for their services based on their experience level and reputation.

Costs Associated with Boiler Repairs

If during your routine boiler service it’s found that repairs are necessary, this will incur additional costs over and above your standard servicing fee. The cost of boiler repairs can vary greatly depending on what needs fixing; however, most homeowners spend between £150 and £400 on boiler repairs.

Common boiler issues that require repair include leaks, pressure problems, ignition issues, and thermostat malfunctions. The cost of these repairs will depend on the severity of the problem and the cost of replacement parts if needed.

Why Regular Boiler Service is Crucial

Regular boiler servicing is crucial for several reasons:

1. Safety: A poorly maintained boiler can produce carbon monoxide, a deadly gas that’s difficult to detect because it’s colorless and odorless. Regular servicing ensures your boiler is safe to use.

2. Efficiency: Regular maintenance helps keep your boiler running efficiently, which can save you money on energy bills.

3. Longevity: Regular servicing can extend the lifespan of your boiler, saving you from costly replacements.

4. Prevents Breakdowns: Routine checks can help identify potential issues before they become major problems, reducing the likelihood of unexpected breakdowns and expensive repairs.

5. Warranty: A boiler that is still in warranty must be serviced annually by a registered gas engineer in your area. If you need help with finding a registered gas engineer, click here.

What’s Included In A Boiler Service


1. A visual inspection will be carried out to look for any signs of damage, and identify any signs of distress that are immediately visible.

2. Boilers have a number of controls and safety devices that must be tested for correct operation. A gas safe registered engineer will check that your controls as well as the safety devices on the boiler are working and safe for you to use.

3. Combustion readings will be checked to ensure the boiler is burning efficiently as well as checking for the flue integrity and there are no blockages in the flue.

4.  Cleaning components if required such as the main heat exchanger although this is not normally required every year. The condensate trap needs to be cleaned out to prevent a build up of the particles at the bottom of the trap. The electrodes need to be checked for correct spacing and if required cleaned off with a wire brush.

5. Checks such as the burner or operating pressure of the boiler must be carried out. A gas rate must be carried out to ensure that the gas pipe size is correct. The expansion vessel should be checked to ensure that it is charged to the right pressure.

The water quality should be checked annually to ensure that your heating system is clean. A dirty heating system will eventually cost you money on expensive boiler repairs. Not all gas engineers check for water quality so ensure that you ask them to do this as it’s extremely important.

6. Once all the cleaning and checks have been completed the engineer should ensure the boiler is working correctly. Any controls or settings that were altered during the service will be either put back to the customer’s settings or left so that the customer can easily adjust the settings themselves.

7. The engineer should record the data from the combustion readings as well as the gas pressure checks and provide you with either a copy of a service record or write the findings insided the service record in the back of the installation manual.

This would be required anyway if the boiler is under warranty so ensure that this is signed off otherwise you risk losing the warranty if the boiler needs parts replaced.


Boiler service Checklist | Letsgo TNT Gas & Heating Engineers



While it might be tempting to skip regular boiler services to save money in the short term, this could end up costing you more in the long run due to higher energy bills and potential repair or boiler replacement costs. Therefore, it’s recommended to have your boiler serviced annually by a registered gas safe engineer.

Remember that while the boiler service cost is an important factor when choosing an engineer for your service or repairs, it shouldn’t be the only consideration. Ensure they are Gas Safe registered (for gas boilers) or OFTEC registered (for oil boilers) as this indicates they have received proper training and are qualified to work safely on boilers.

In conclusion, while there are costs associated with maintaining your home’s heating system, regular service checks and timely boiler repairs are investments that ensure efficiency, safety, and longevity of your appliance.
