How Often Should You Service Your Boiler? UK Guide for 2026
Arrange a boiler service at the interval in the manufacturer’s instructions, usually every year. Check the service and guarantee documents for your model. A new boiler still needs its scheduled maintenance; a missed visit is a reason to arrange a service and check the terms, not to assume every warranty is automatically lost.

| Booking | What to confirm |
|---|---|
| Boiler service | Manufacturer service procedure, appliance condition and a completed service record. |
| Landlord gas safety check | The appliances and flues covered, access and the resulting gas safety record. |
| Both together | Confirm both tasks are included; a combined visit does not make them the same service. |
For a gas boiler, use an appropriately qualified Gas Safe registered engineer. If you need local help, our Leicester boiler service page explains how to make an enquiry.
Why the service interval matters
A service is planned maintenance. It gives the engineer an opportunity to check the appliance, identify deterioration and carry out the work specified for that model. It does not guarantee that no fault will develop afterwards.
Keep the installation details, service record and guarantee terms together. Before booking, tell the engineer the make, model and any faults. Ask which documents will be updated and whether any additional work requires a separate quote.
What should a boiler service include?
The exact checks and cleaning depend on the appliance and the manufacturer’s service instructions. Do not judge a service only by a promised number of minutes or assume every model needs identical dismantling. Ask for an explanation of the work carried out, the results and any follow-up needed.
- Confirm that the engineer is qualified for your appliance and fuel type.
- Explain any leaks, noises, error codes or changes in heating or hot water.
- Check whether the quote includes the system filter, any additional appliances and applicable VAT.
- Ask for the service record and a clear explanation of faults or recommended repairs.
Landlords: servicing, maintenance and annual safety checks
For landlords in England, the duties include maintaining the relevant gas appliances, flues and installation pipework, arranging the required annual appliance/flue safety checks, and providing the gas safety record. The scope depends on matters such as who owns the appliance. HSE explains what needs an annual gas safety check.
A service and a gas safety check do different jobs. Booking one does not automatically include the other. HSE says appliances and flues should be serviced to the manufacturer’s instructions; where these are unavailable, it recommends annual servicing unless the Gas Safe engineer advises otherwise. Read HSE’s maintenance guidance.
The gas safety record, often called a CP12 or landlord gas safety record, records the checks and results; it is not a promise that every fault has been repaired. Existing tenants normally need a copy within 28 days, and new tenants before they move in. HSE sets out the record and retention requirements.
If you need both a service and a landlord gas safety check, specify both when requesting the appointment and confirm the appliance count, price and access arrangements.
When to arrange help before the next service
Do not wait for a diary date if the boiler leaks, develops a recurring fault or shows an abnormal reading. Contact an engineer and describe the problem. Any shorter routine interval should come from the manufacturer’s instructions or an assessment of the installation, rather than a blanket six-month rule for older homes.
Frequently asked questions
Does a brand-new boiler need an annual service?
Check the manufacturer’s schedule and guarantee conditions from installation. Set a reminder before the first service is due and keep the completed record.
What time of year should I book?
Book before the service is due. A convenient summer or early-autumn appointment can help with planning, but do not let a required date pass while waiting for a preferred season.
How much does a boiler service cost in Leicester?
Ask for a quote for your model and confirm what is included. A landlord check, extra appliance, fault diagnosis or repair may be priced separately.
Can I service my own gas boiler?
Arrange the service with an appropriately qualified Gas Safe registered engineer. Limit householder tasks to those expressly described in your user manual; do not remove the sealed casing or adjust internal components.
What if I have missed a service?
Arrange one and explain the gap. Check your guarantee provider’s terms directly rather than assuming cover is either valid or void. Landlords must also deal with any overdue safety check and maintenance duties promptly.
