How often should I get a boiler service?

You should aim to get your boiler serviced annually to ensure its safe and efficient operation.

Annual boiler servicing helps identify and address any potential issues early, preventing breakdowns, reducing safety hazards, or having a faulty boiler down the line, maintaining optimal performance.

Additionally, regular servicing helps prolong the lifespan of your boiler and ensures that it continues to operate reliably throughout the year.

Therefore, scheduling a boiler service on an annual basis is recommended to keep your heating system in good condition and provide peace of mind for your household.

Do you have to service your boiler every year by law?

In the United Kingdom, there isn’t a specific law that mandates homeowners to service their boilers every year. However, there are legal requirements regarding the safety of gas appliances, including boilers.

The Gas Safety (Installation and Use) Regulations 1998 stipulate that landlords are legally obligated to ensure that gas appliances, including boilers, are maintained in a safe condition.

This typically involves annual gas safety checks conducted by Gas Safe registered engineers.

While there isn’t a legal requirement for homeowners to service their boilers annually, servicing your boiler regularly is strongly recommended to comply with manufacturer warranties.

Additionally, regular servicing can help identify and address potential safety hazards and ensure that the boiler operates reliably. Therefore, while not mandated by law for homeowners, annual boiler servicing is considered the best practice for maintaining a safe and efficient heating system.

How much does a boiler service cost?

The cost of a boiler service can vary depending on various factors such as the location, the type of boiler, and the service provider.

On average, a boiler service in the UK typically ranges from £70 to £120. However, the actual cost may be influenced by additional factors such as any required repairs, the complexity of the boiler system, and any special requirements.

Some service providers may offer discounted rates for servicing your boiler regularly or bundle servicing with other maintenance tasks.

It’s advisable to obtain quotes from multiple service providers and compare their offerings to ensure you receive a competitive price while ensuring your boiler receives thorough and professional servicing to maintain its efficiency and reliability.

Do I need a Gas Safe Engineer to service my boiler?

You need a Gas Safe registered engineer with a gas safety certificate to service your boiler. Qualified heating engineer with a Gas Safe register are trained and qualified to work safely and legally on gas appliances, including boilers.

They have the expertise to conduct thorough inspections, identify any issues, and perform necessary repairs or maintenance tasks to ensure the safe and efficient operation of your boiler.

Hiring a registered gas engineer for your boiler service provides assurance that the work will be carried out professionally and in compliance with industry regulations and safety standards, minimising the risk of accidents, leaks, or other safety hazards associated with gas appliances, and can perform a gas safety check.

Therefore, it is essential to engage a Gas Safe registered engineer for the servicing of your boiler.

OFTEC engineers adhere to strict industry standards and regulations to ensure the safe and efficient operation of oil-fired heating systems.

Do Surveyors check the condition of boilers when selling a house?


Yes, surveyors may check the condition of boilers as part of their assessment during property surveys when selling a house. When conducting a home inspection or survey, surveyors may inspect the boiler to assess its age, condition, and functionality.

They may look for signs of wear and tear, corrosion, leaks, or other issues that could affect the boiler’s performance and safety.

While surveyors may provide observations on the general condition of the boiler, it’s important to note that their assessments may not be as detailed as those conducted by qualified engineers during a professional boiler service.

Should you check your boiler before buying your new home?


Before purchasing a new home, it’s highly important to check the condition of the boiler.

Assessing the boiler’s functionality is essential for safety, cost considerations, comfort, and negotiation purposes.

Ensuring that the boiler is in good working condition helps prevent safety hazards like gas leaks and carbon monoxide emissions while also providing reliable heating and hot water for the occupants.

By hiring a qualified heating engineer or Gas Safe registered engineer to conduct a thorough inspection, potential buyers can gain valuable insights into the boiler’s condition and performance, allowing them to make informed decisions and potentially negotiate repairs or adjustments with the seller.
