Servicing your boiler is an essential maintenance task that ensures your heating system runs efficiently and safely. As we enter another year with rising energy costs and cost-of-living crisis, it’s important to understand the current costs associated with this crucial home maintenance procedure. In this comprehensive blog, we’ll explore the factors that influence boiler service costs, average prices for different types of boilers, and tips to help you get the best value for your money.
Average Boiler Service Cost
The cost of a boiler service can vary depending on several factors, but on average, you can expect to pay between £70 and £130 for a standard service. However, prices can range from as low as £60 to as high as £180 in some cases. In the next section we will have a look at the average costs of different types of boilers.
1. Gas Boiler Service
Gas boilers are the most common type in UK homes. The average cost for a gas boiler service typically falls between £80 and £110. Some sources suggest that prices can be as low as £70 or as high as £120, depending on various factors such as location and the specific requirements of your boiler. If you are a homeowner on benefits, you can check your eligibility for a new free combi boiler. ECO Boiler Grants only installs reliable heating systems with extended warranties that can reach as far as 12 years. So, you can sit back and relax not having to worry about the cost of servicing!
2. Oil Boiler Service
Oil boilers generally cost more to service than gas boilers. The average price for an oil boiler service ranges from £75 to £180. This higher cost is often due to the additional work involved, such as cleaning oil filters and inspecting fuel tanks.
3. Electric Combi Boiler Service
Electric combi boilers tend to be the least expensive to service. You can expect to pay between £60 and £100 for an electric combi boiler service.
4. Commercial Boiler Service
For those with commercial properties, the cost of a boiler service is typically higher. Commercial boiler services average around £95, but prices can vary significantly depending on the size and complexity of the system.
The Different Factors That Can Affect Boiler Service Costs
Several factors can influence the cost of your boiler service. Understanding these can help you anticipate potential expenses and make informed decisions.
Your Location can significantly impact the cost of your boiler service. As with many services, prices tend to be higher in London and other major cities compared to rural areas. For example, a boiler service in London might cost up to £120, while the same service in a less urban area will be considerably cheaper.
The type of boiler you will also play a crucial role in determining service costs. Combi boilers, being the most common, are often the cheapest to service. System and conventional boilers may require more time and effort, potentially increasing the cost.
The age of your boiler is another important factor. Older boilers may need more attention and possibly replacement parts, which can drive up the service cost. If you’re unsure about your boiler’s age, you can check the serial number on the unit or contact the manufacturer for this information. If you have an old boiler, you might be eligible through the LA Flex scheme for a new combi boiler even if you do not qualify through the ECO4 scheme.

When you schedule your boiler service may impact the cost. Summer tends to be the lowest-cost time of year to have your boiler serviced because heating engineers have less work to perform in the summer. Winter servicing is more costly because demand is higher and there is a higher probability of a breakdown occurring.
The person or organisation you get to service your boiler can also vary the cost. National large organisations are more expensive than local independent, smaller organisations. However, you should also make sure whoever services your boiler is Gas Safe registered for gas boilers or fully qualified in the case of oil, LPG, or alternative boilers. ECO Boiler Engineers are all Gas Safe registered engineers. We only install the best boilers from companies like Worcester Bosch to ensure that you get the best quality systems with reliable warranties that allow for good servicing.
What Does a Boiler Service Entail?
To understand the value you’re getting for your money, it’s helpful to know what a standard boiler service consists of. A standard boiler service will normally include:
- External inspection of the boiler and components
- Leak and corrosion tests
- Checking the operation and safety controls of the boiler
- Cleaning of key parts
- Checking the gas pressure and flow rates if it’s a gas boiler.
- Flue check for blockages and proper ventilation
- Testing of controls and thermostats
- Service report provision
Each standard servicing will typically last 1-2 hours. If there are a few problems with the servicing, the engineer might suggest extra repairs or replacement, which could add to the cost!
The Difference Between a One-off Service and Boiler Cover Plans
Each time you make a decision to have your boiler serviced, you have to consider one of two options: either pay for the one-off servicing or purchase a boiler cover plan.
A one-off service is to pay once for an annual boiler check. This would be between £70 and £130. The benefit of doing this is that you only pay for what you want to, and if your boiler is fairly new and efficient, this could be the cheapest option.
A boiler cover policy on the other hand is about paying a yearly or monthly premium for cover all year round. Such policies usually come with an annual service and cover for repairs if your boiler is defective. Boiler cover policies cost between £100 and £200 annually on average.
While boiler cover policies may provide reassurance, they may end up costing you more in the long run if you don’t need to claim. However, if you have an older boiler or one that likes to act up, a cover policy may be worth it, as it could end up saving you money on costly repairs.
Tips for Saving on Boiler Services
- Book your service in the summer when there is less demand, and you will obtain better rates.
- Ask for quotes from a couple of different providers so you can be sure you are getting a decent price.
- Have regular annual services to avoid costly repairs in the future.
- If your boiler is old and constantly breaking down, it may be cheaper to replace it with a newer, more efficient one.
- Some home insurance policies include boiler breakdown cover, so check if you already have this cover before you buy extra cover.
- Some firms offer a discount if you book several services together, such as a boiler service and a gas safety check.
Even though the cost of boiler servicing may seem unnecessary, particularly if your boiler seems to be in decent condition, servicing is important for a number of reasons. It is crucial for your safety. A serviced boiler has a less chance of harboring hazardous faults that may result in carbon monoxide leaks or other safety issues.
Another important reason is the fact that ongoing servicing ensures your boiler operates at its best efficiency, which can lower your energy costs. This will in turn lengthen the lifespan of your boiler, delaying the requirement for a costly replacement.
It is also important to consider that a number of boiler warranties need servicing on an annual basis to stay in force.
For landlords, annual gas safety checks (which involve boiler checks) are legally necessary.
Summary
The price of a boiler service in 2025 can differ greatly and usually ranges from £70 to £130 for a standard check. Location, model, age, and servicing company are some of the elements that determine the final cost. Though it may be tempting to do without this yearly maintenance to save money, the long-term advantages of maintaining your boiler on a regular basis – such as enhanced safety, efficiency, and lifespan of your boiler are well worth the expense.
When you budget for boiler maintenance, don’t simply look at the upfront cost but also at the possible long-term energy bill and repair cost savings. By selecting a good firm, having your maintenance done at the right time, and looking at options such as boiler cover schemes where relevant to your circumstances, you can keep your heating system in the best possible condition without overspending.
Keep in mind, a serviced boiler is not merely a matter of convenience, it’s also an investment in safety and efficiency within your home. By understanding all about boiler service costs and choices, you will be able to make the most-informed decisions possible for your home and your family, as well as your finances.
