Boiler servicing is an essential aspect of maintaining a safe and efficient heating system in any home or commercial building. With regular checks and maintenance, potential issues can be identified early on, preventing expensive repairs or replacements in the future. In addition, a well-serviced boiler can ensure optimal energy efficiency, resulting in reduced energy bills and a smaller carbon footprint.

The cost of boiler service can differ depending on multiple factors, such as the type of boiler (gas or electric), the complexity of the service needed, and the specific engineer or service provider chosen. The average cost of a boiler service in 2023 generally falls between £70 to £110 for a gas boiler, and slightly less for an electric version. While annual servicing is often recommended, those seeking additional peace of mind may opt for boiler cover, typically costing £200 to £300 per year.

It is important to shop around and compare costs, as boiler servicing prices can vary significantly between companies. By weighing the pros and cons of one-off servicing versus ongoing boiler cover, homeowners and property managers can make informed decisions when it comes to taking care of their heating system and avoiding unwanted breakdowns during colder months.

Key Factors Determining Boiler Service Cost

Type of Boiler

The type of boiler plays a significant role in determining the service cost. Wall-mounted boilers are generally less expensive to service, with routine inspection and maintenance typically costing between £60 to £90. On the other hand, floor-standing or larger boilers may have higher service costs due to their size and complexity.


The location of the boiler and the area you reside in can also impact the overall boiler service cost. Service prices may vary across different regions in the UK due to differences in local labour rates and availability of engineers. It is important to get quotations from local boiler service providers to obtain accurate pricing for your area.

Existing Boiler Condition

The condition of your existing boiler is another important factor that influences the cost of boiler service. A poorly maintained boiler with multiple issues may require more extensive repairs, resulting in higher service costs. In contrast, a well-maintained boiler will only need routine maintenance, keeping costs within the average range of £79 to £90.

Regular boiler servicing is crucial to ensure the efficient functioning of your boiler. Factors such as the type of boiler, location, and the condition of the existing boiler play a crucial role in determining the cost of servicing. Stay informed and consider these key factors when budgeting for your boiler service.

Cost Breakdown

The cost of boiler service can be better understood through two primary components: labour costs and parts costs. By breaking down these costs, it becomes clear what factors contribute to the overall boiler service expense.

Labour Costs

The labour costs for boiler servicing depend on the company performing the service and the location. Independent boiler servicing companies typically charge between £60 to £90, including VAT for a routine inspection and maintenance service of a wall-mounted boiler. As a point of reference, the average boiler service cost in the UK is approximately £79-£90 in 2023.

It is essential to note that these costs cover the inspection and maintenance service. If there are additional repairs or part replacements required, the labour costs may increase accordingly.

Parts Costs

In addition to labour, parts costs also contribute to the overall cost of boiler servicing. The average cost of repairing a boiler, including parts, falls in the range of £100 - £500. The common parts that may need repair or replacement in boilers include the thermostat, ignition system, and pressure relief valve, among others.

When evaluating the overall boiler service cost, it is crucial to consider the quality of the parts being used for repairs or replacements. Investing in high-quality and durable components can prevent long-term expenses and ensure a more efficient boiler performance.

In conclusion, understanding the cost breakdown of boiler services can help homeowners make informed decisions when it comes to servicing or repairing their boilers. Estimating the labour and parts costs will provide a clear picture of the overall service expenses and help choose the right service provider.

Additional Costs

Emergency Call Out Charges

In some situations, boiler issues may require an immediate response, which leads to the need for an emergency call-out service. These charges can be significantly higher than a standard boiler service, as they often involve after-hours work or urgent attention. Emergency call out charges usually range from £100 to £150, depending on the location and the specific issues being addressed. Keep in mind that these fees are separate from any necessary repair costs that may arise during the service.

Additional Repair Costs

During a routine boiler service, the technician may discover underlying problems that require additional repairs. These repair costs can vary widely, depending on the extent and complexity of the issue. Some common repair scenarios and their approximate costs include:

  • Installing a new heat exchanger: £300-£700

It's essential to be aware of these potential extra costs when budgeting for a boiler service, as they can significantly impact the total service expense.

Cost Comparison With New Boiler Installation

When considering the cost of servicing a boiler, it is important to also take into account the cost of a new boiler installation. A new boiler can range from £2,000 to £4,000 for supply and installation, depending on the type and model. The running cost for a gas boiler starts at £90 per month, with most boilers having a lifespan of around 10 to 15 years.

With average boiler service costs being approximately £100 annually, homeowners should weigh the benefits of regular servicing against the potential savings of a new, more energy-efficient boiler. It is worth noting that new boilers can have an efficiency rate of over 90%, while older models may have an efficiency rate lower than 50%.

In a comparison of costs over a 10-year period, an annual boiler service costs £1,000 (excluding any additional repairs needed), while a new boiler installation could potentially save on energy bills and reduce the need for more expensive service-related repairs.

However, it is also crucial to acknowledge that new boiler installations may come with their own maintenance requirements. This includes the initial installation cost (£2,000 - £4,000) and ongoing servicing costs. Moreover, homeowners should consider the availability of boiler cover, which ranges from £8 to £13 per month and can provide additional peace of mind.

To summarise, when determining the right course of action, homeowners must examine their boiler's age, efficiency, and the associated service, repair, and installation costs. While a new boiler installation may be more cost-effective in the long run, regular servicing is crucial to extending the lifespan and optimising the performance of an existing boiler.

Ways to Save on Boiler Service Cost

Annual Service Plans

One effective way to save money on boiler service costs is to opt for annual service plans. By paying in advance with a monthly direct debit, you can spread out the costs over the year. This can be more affordable than a one-off boiler service, which may cost you between £60 and £120. Furthermore, annual service plans can help you maintain your boiler warranty, as most manufacturers stipulate that a yearly service is required after registering a new boiler.

Energy Efficiency Measures

Another approach to reducing boiler service costs is by implementing energy efficiency measures. By ensuring that your heating system is running efficiently, you can lower both energy consumption and the likelihood of expensive repairs. Several energy efficiency measures that can be applied to boilers include:

  • Regular maintenance: Keeping your boiler well-maintained will help it operate more efficiently and extend its lifespan. The average cost for a boiler service ranges from £60 to £120.
  • Insulation: Proper insulation in your home will lessen the demand on your boiler, making it work less and decreasing the risk of breakdowns.
  • Upgrade to a more efficient boiler: If your boiler is more than 10 years old, it might be worth considering replacing it with a newer, more energy-efficient model. This could help you save money on heating bills and reduce the need for frequent servicing.

By incorporating annual service plans and taking energy efficiency measures, you can effectively save on boiler service costs and keep your home heating system functioning optimally.


In summary, the average cost for a boiler service in 2023 ranges from £60 to £110, depending on factors such as the type of boiler (gas or electric), the service provider and the location. Boiler servicing is a necessary annual maintenance routine that ensures the efficiency and safety of your boiler.

The cost of boiler cover can vary, with prices ranging from £8 to £13 per month. This alternative to a one-off service provides peace of mind all year round, potentially covering any additional repair costs that might arise if faults are discovered during the service.

When considering boiler service providers, it is essential to compare the prices and services offered by different companies. By doing this, one can make an informed decision and obtain the best value for their money. It is also crucial to ensure that the provider is reputable and accredited, to guarantee high-quality service and adherence to safety regulations.

In conclusion, staying informed about boiler servicing costs and options can save homeowners money in the long run and ensure a safe and effective heating system for their home.
