Boiler Servicing

Boiler Safety Check

A boiler safety check helps confirm your boiler is running safely and correctly, with clear findings you can act on. It focuses on safe operation, key component checks and combustion testing where applicable, without a full strip-down service.

More information

What a boiler safety check covers

A safety check is designed to spot issues early, confirm safe performance, and give you a clear view of what is and is not working as it should.

  • Visual inspection of accessible boiler components and pipework
  • Checks for leaks, corrosion, overheating signs, and safe clearances
  • Flue condition and positioning checks (where accessible)
  • Ventilation and condensate discharge checks (as applicable)
  • Safety device checks (for example pressure relief and shutdown functions)
  • Operating pressure and basic performance checks
  • Combustion analysis and flue gas readings where appropriate for the appliance
  • Cleaning of accessible parts where required for safe operation
  • Confirmation of correct start-up, burner operation and shutdown
  • Practical written summary of findings and recommended next steps

When a boiler safety check is the right choice

This service suits homeowners who want reassurance before heavy use, landlords planning maintenance between tenancies, and small premises that rely on consistent heating and hot water. It is also a sensible step if you have noticed unusual noises, intermittent lockouts, a yellow flame, soot marks, or a change in boiler performance. If you need a formal landlord gas safety record for a rental property, you may need a separate Gas Safety Certificate that covers all relevant gas appliances.

What happens during the visit

The engineer will confirm the boiler type and fuel, then carry out a series of safety and operating checks, keeping disruption to a minimum. Testing may involve running the boiler, taking combustion readings, and inspecting the flue and key safety controls. This is a safety-focused check rather than a full strip-down service, so any deeper strip-down work is discussed separately if needed.

After the check

You will receive a clear summary of what was checked, what is working correctly, and any faults or risks found. If any issues need repair, you will be advised on priority, options, and likely next steps so you can make an informed decision. Many clients use the findings to plan repairs early and reduce the risk of breakdowns during colder months.

Frequently Asked Questions

Is a boiler safety check the same as a full boiler service?
Not always. A safety check focuses on safe operation and key tests without a full strip-down. If your boiler needs a deeper clean or manufacturer-specific service tasks, a full service may be recommended.
How often should I book a boiler safety check?
Most households book annually, often before winter. Landlords and small premises may also schedule checks around tenancy changes or periods of heavy use. If you notice unusual symptoms, book sooner.
Does this provide a landlord Gas Safety Certificate (CP12)?
A boiler safety check is not automatically the same as a landlord gas safety inspection. A Gas Safety Certificate is a specific legal check and usually covers all relevant gas appliances in the property. Ask when booking so the correct service is arranged.
What will I need to provide access to?
Clear access to the boiler, controls, and where possible the flue route and any external terminal. The engineer may also need access to the gas meter, electrical isolator, and a nearby water filling loop if fitted. If parts are boxed in, you may be asked to open panels or cupboards.
What happens if you find a fault or safety issue?
You will be told what has been found and what it means in practical terms. If an issue is unsafe, the engineer will explain any immediate steps needed before leaving the appliance running. You can then choose whether to proceed with repair work and agree any costs in advance.
