Boiler Servicing

Annual Boiler Service

An annual boiler service helps keep your heating running safely and efficiently, reduces the risk of unexpected breakdowns, and provides a clear record of checks and performance. It is a practical way to protect your home, support manufacturer requirements, and spot issues early before they become costly repairs.

More information

What an annual boiler service covers

A routine service focuses on safety, performance and reliability, with clear feedback at the end.

  • Visual inspection of the boiler, flue and nearby pipework
  • Checks for safe operation and correct ventilation
  • Inspection of key internal components for wear and leaks
  • Cleaning of parts where required to support efficient running
  • Combustion analysis (where applicable) to confirm safe burning
  • Operational checks of controls, temperature and pressure
  • Identification of faults, risks, or signs of deterioration
  • Written service record and practical recommendations

When an annual service is most important

  • Before peak winter use, to reduce the chance of a no-heat callout
  • If your boiler is ageing, noisy, or cycling on and off
  • If you have noticed higher bills or slower heat-up times
  • When you move into a new property and want a baseline condition check
  • For landlords who need a consistent maintenance trail across tenancies

How the appointment works

The engineer confirms the boiler make and model, then carries out a structured set of checks and tests. The casing is removed where appropriate so components can be inspected, cleaned and assessed, followed by performance testing and safe reassembly. You will be talked through what was found in plain English, with clear next steps if anything needs attention.

After the service

You receive a record of the service and any notes on performance or safety. If an issue is identified, you can choose whether to book a repair, plan preventative work, or monitor it with guidance on what to watch for. Many clients schedule the next annual service in advance to stay on top of maintenance.

Frequently Asked Questions

How often should a boiler be serviced?
Most manufacturers recommend servicing once a year. Annual servicing helps maintain safe operation, supports efficiency, and can help spot developing faults early.
What does an annual boiler service include?
A service includes safety checks, inspection of key components, performance testing and cleaning where needed. You will also receive a written record and clear advice on any issues found.
Do you service gas and oil boilers?
Yes, gas and oil boilers can be serviced, provided the engineer attending is appropriately qualified for that fuel type. If you are unsure what you have, share the boiler make and model when booking.
Will a service fix my boiler if it has stopped working?
A service is preventative maintenance and may not resolve an active fault. If the boiler is not working, it is usually better to book a repair visit so time can be allocated for diagnosis and parts if required.
Do I get a certificate or record after the service?
You will receive a service record confirming what checks were completed and any findings. If you need a Landlord Gas Safety Record (CP12), that is a separate visit and document.
