Annual boiler servicing
Regular care, even when the heating seems fine.
Servicing your boiler gives an opportunity to check its condition and operation, carry out maintenance required by the manufacturer and identify concerns that need further attention. It does not mean an appliance can never develop a fault between visits.
Follow the service recommendations for your model. HSE advises annual servicing of gas appliances by a suitably qualified Gas Safe registered engineer. See its domestic gas safety guidance and our wider gas and heating services.
Inspection and maintenance
What a boiler service typically involves.
- Condition and signs of wear
- Inspection considers the appliance condition, signs of leakage or deterioration and accessible connections. Cleaning and other service tasks depend on the model and manufacturer instructions; not every boiler needs identical work at each visit.
- Combustion, flue and ventilation
- Relevant checks consider combustion performance, the flue arrangement and ventilation, using the procedures specified for the appliance. Any unsafe finding needs attention rather than simply recording that a service has taken place.
- Controls and safe operation
- The boiler controls and safety functions are checked as applicable to the appliance. Tell us about changes in operation or any fault codes before the visit so an existing problem can be distinguished from routine maintenance.
Servicing or repairs?
Mention existing problems before booking.
Repeated pressure loss, leaks, new noises, fault codes or unreliable heating and hot water need investigation. Our boiler repair service explains diagnosis and the work involved. A routine service should not be assumed to resolve an existing breakdown.
If assessment leads to a discussion about different equipment, our boiler installation page covers replacement considerations. Neither a missed service nor the age of a boiler automatically means it needs replacing.
A service is not a landlord gas safety inspection
Boiler servicing and a landlord gas safety check, with its record commonly called a CP12, are different tasks. Maintenance looks after the appliance; a landlord inspection checks the relevant gas appliances and flues for the required safety record.
Do not assume one includes the other. If both are required, say so when arranging the work and agree the scope. HSE's landlord gas safety guidance explains the distinction between maintenance and safety checks.
Planning the visit
From appliance details to a service record.
Share the boiler details
Include your postcode, boiler make and model if known, last service date and available records. Mention any faults or access restrictions when booking rather than wait until the service begins.
Agree the service scope
We discuss the appliance and work required under its service instructions. Clear access to the boiler and relevant controls is needed, and operation may be interrupted during the checks.
Inspect and service
The service follows the relevant manufacturer procedures, including applicable inspection, cleaning and operational checks. Gas work must be carried out by a Gas Safe registered engineer qualified for the appliance.
Explain and record the findings
We discuss the results, record the service and explain any additional investigation or repairs advised. Further work should be agreed separately; a routine service does not automatically include replacement parts or repairs.
Scope and cost
What affects the service quote?
- Appliance and service requirements
- The boiler model, its condition and the manufacturer service procedure influence the work. Share the appliance details so the scope can be discussed.
- Access and service history
- Access to the boiler, flue and controls, and available records, help establish what is involved. Mention any known difficulties before arranging the visit.
- Additional work identified
- Fault investigation, repairs or parts may be separate from routine servicing. Ask what is included in the quote and how any further work will be agreed.
Care between service visits
Keep appliance instructions and service records available, leave ventilation unobstructed and report changes in operation. Our boiler maintenance article introduces ongoing care. Do not remove covers or attempt gas or electrical repairs yourself.
If you smell gas or suspect a leak, leave the property and call the National Gas Emergency Service on 0800 111 999 from a safe place. Avoid electrical switches and naked flames, and do not wait for an enquiry-form reply.

Boiler servicing questions
How often should I arrange boiler servicing?
Annual boiler servicing is generally recommended for gas appliances. Follow the manufacturer instructions for your model and any advice given following inspection. Do not wait for the next planned service if the boiler develops a fault or appears unsafe.
What does a boiler service include?
The work follows the appliance service instructions and typically includes inspection, applicable cleaning, combustion and flue checks, and checks of controls and safe operation. The exact tasks depend on the model and condition; discuss the scope when booking.
Is boiler servicing the same as a landlord gas safety check?
No. Servicing concerns maintenance of the appliance. A landlord gas safety inspection and its record, often called a CP12, have a separate purpose. Do not assume a service includes the required landlord check or that a safety check replaces maintenance. Agree both scopes if both are needed.
Should I book a service if my boiler has broken down?
Tell us about the breakdown when enquiring. Pressure loss, leaks, repeated stopping or loss of heating or hot water may need diagnostic work and repair rather than a routine service. The appropriate visit depends on the symptoms.
Do I need the previous service record?
It is useful to have the appliance instructions, commissioning information and previous service records available. If you cannot find them, share the make and model if known and explain any recent work without removing covers to obtain details.
What affects the cost of servicing my boiler?
The appliance, service requirements, condition and access affect the scope. Additional repairs or parts should be discussed separately rather than assumed to be included. Contact us with your boiler details to discuss the service and quote.
