Oil Boiler Service Cost

If you have an oil boiler, the cost for a one-off service ranges between £100 and £140. The cost is influenced by the need to inspect both the oil tank and the boiler itself.

It’s crucial to hire an OFTEC registered engineer for an oil boiler service to ensure proper maintenance and adherence to safety standards.

With these costs in mind, you are better equipped to make knowledgeable choices about your oil boiler service, safeguarding its safety, efficiency, and lifespan.

Back boiler service cost

While a standard boiler service might set you back between £60 and £120, back boiler servicing can cost significantly more, ranging from £80 to a hefty £160.

This price difference boils down to two key factors: accessibility and complexity. Back boilers are tucked away in fireplaces, making them challenging for engineers to reach.

Additionally, servicing a back boiler involves the boiler itself and the connected gas fire service, adding an extra layer of complexity. So, a traditional combi or system boiler is the way to go for a more hassle-free and affordable service.

What is included in boiler service costs?

Being aware of what a boiler service entails helps us understand the expenses. A typical service includes:

  • Visual assessments of the unit for leaks or corrosion
  • Testing of the boiler operations and controls
  • Inspection and cleaning of internal components like the spark probe, main injector, and heat exchanger
  • Inspection of the flue terminals and pipework to prevent blockage and identify wear

Further, the engineer conducts a series of safety and efficiency tests, adjusts the gas pressure and flow, and ensures all safety devices within the boiler are functioning correctly.

From this, you can appreciate the comprehensive work involved in a boiler service and why it’s a crucial aspect of home maintenance.

The Importance of Annual Boiler Servicing

Annual boiler servicing extends beyond basic maintenance. It is a critical measure for ensuring the safety of your home and its occupants, and you should get your first boiler service 12 months after the date of the new boiler installation.

Regular servicing helps prevent risks of carbon monoxide poisoning from gas boiler leaks, which can be life-threatening.

By addressing boiler issues during an annual boiler service, you can prevent them from developing into significant, hazardous damages.

Moreover, regular boiler servicing offers several benefits:

  • Efficiency improvements, which can lower your energy bills over time
  • Keeping a boiler warranty valid and avoiding out-of-pocket expenses for potential replacements
  • Adhering to annual servicing requirements

Overall, boiler servicing is an economically prudent practice as it’s more cost-effective than replacing a boiler, and it prevents expensive breakdowns, including the need for boiler repairs.

Safety Concerns

Frequent boiler servicing guarantees safe operation and aids in preventing carbon monoxide poisoning, whose symptoms can be mistaken for common illnesses. Consequently, annual servicing isn’t just advantageous, it’s a necessity for your safety.

Efficiency and Lifespan

Getting a boiler service often or Routine boiler servicing contributes significantly to energy efficiency savings. A well-serviced boiler can last between 10 to 15 years.

This maintenance practice promotes energy savings by ensuring optimal boiler performance and efficiency.

If your boiler is not serviced you will not benefit from reduced energy consumption from efficient boiler operation helps save on energy costs, making annual boiler servicing a sound investment for the long run.

Comparing Boiler Service Plans and One-Off Services

Boiler maintenance can be approached in two ways: subscribing to a boiler service plan or opting for a one-off boiler service.

finance plans

When deciding between the two, consider the boiler’s age and its repair history. While annual costs for boiler and heating cover plans average between £100 and £200, one-off services might be a cost-effective option for some.

While boiler cover plans might seem pricier initially when compared to one-off services, they provide extra comfort with their coverage for repairs and breakdowns.

Comprehending the advantages and drawbacks of both alternatives enables you to make a decision that best fits your particular needs and situation.

Boiler Cover Plans

Boiler cover plans aim to provide homeowners with the assurance of annual servicing and additional repair coverage. A boiler cover plan is essentially an insurance policydesigned to provide service and repair in case of a boiler breakdown.

cover protection

For instance, the Service Plan by Boiler Central, at £8.99 per month, includes one annual service, whereas the boiler and central heating cover plan, at £21.99 per month, extends coverage to include the central heating system along with the annual service.

While boiler cover plans may seem more costly upfront, they can ease financial strain by offering consistent cash flow management through regular payments and inclusive repair coverage.

They are popular among homeowners who rely on natural gas as their heating source and seek customisation to meet specific needs and ensure complete protection from unforeseen breakdowns.

One-Off Boiler Services

On the other hand, one-off boiler services allow homeowners the flexibility to pay as needed and choose from a variety of service providers.

They are a suitable option for individuals not covered by boiler insurance or whose boilers are out of warranty. Opting for one-off services allows you to address maintenance issues as they arise rather than through annual plans, potentially leading to cost savings.

Ultimately, the choice between a boiler cover plan and a one-off service depends on your unique circumstances and preferences.

Does the Time of Year Affect Servicing Costs?

Wondering when to schedule your boiler service? Here are some reasons why arranging a boiler service during the summer months might be more economical:

  • Decreased demand for engineer services often results in lowered fees.
  • Summer is an advantageous time for boiler servicing due to generally shorter waiting times.
  • More scheduling options are available during the summer months.
  • The reduced importance of heating systems during warmer months makes it a convenient time for servicing.

Furthermore, opting for boiler maintenance during summer can dodge additional financial strains associated with the winter holiday season, when household expenses usually increase. So, as you enjoy the warm weather, remember to get your boiler serviced and ready for the colder months ahead.

Preparing for Your Boiler Service

Preparing for your boiler service? Consider these suggestions:

  • Clear the area around the boiler to provide unhindered access for the servicing engineer, and remove any obstacles that could pose a safety risk.
  • Keep pets away from the boiler area to avoid distractions or accidents during the service.
  • Ensure the boiler is turned off before the technician’s visit to allow sufficient time for it to cool down.

Additionally, perform a basic visual inspection for signs of water ingress or soot deposits prior to the technician’s arrival. Inform the service engineer of any issues or irregularities you’ve noticed during your own inspection. This preparation can help ensure a smooth, efficient service and prevent any potential issues during the servicing process.


In summary, understanding boiler service costs is crucial for homeowners. Regular servicing, whether through a boiler service plan or a one-off service, ensures the safety and efficiency of your boiler, ultimately reducing energy bills and extending its lifespan.

Choosing the right engineer and preparing for the service enhances the process’s effectiveness and efficiency. Therefore, when it comes to boiler servicing, knowledge is power – it allows you to make informed decisions, ensuring that your boiler keeps your home warm for years to come.
