Boiler Efficiency Check

A boiler efficiency check assesses how well your boiler is running and whether it is operating safely and economically. You get a clear view of performance, practical ways to reduce wasted energy, and early warning of issues that could lead to breakdowns.

More information

What a Boiler Efficiency Check covers

This service focuses on how effectively your boiler is operating, alongside the core safety and function checks needed to interpret performance accurately.

  • Visual inspection of the boiler, pipework and key components
  • Checks for safe operation of the flue and ventilation
  • Operating pressure and temperature checks
  • Combustion analysis (where applicable) to assess burn quality and efficiency
  • Inspection of burners, heat exchanger and seals, with cleaning where required
  • Confirmation that controls and safety cut-outs work correctly
  • Identification of wear, leaks, corrosion or overheating risks
  • Straightforward feedback on findings and recommended next steps

When this service is most useful

Book a boiler efficiency check if you want to reduce running costs, keep tenants comfortable, or avoid disruption from unexpected faults. It is also a sensible choice if your bills have risen, your boiler is short-cycling, rooms heat unevenly, or the boiler is noisier than usual.

What happens during the visit

You will be asked about any symptoms and how you use heating and hot water. The engineer will inspect the boiler, run targeted tests, take readings and confirm correct operation. For gas or oil appliances, testing is completed by an appropriately qualified engineer.

After the check

You will receive clear advice on adjustments, repairs or maintenance that could improve efficiency and reliability. If parts are worn or performance is poor, you can choose whether to proceed with remedial work, request a quote, or plan follow-up servicing. If a safety issue is identified, you will be advised on the safest next step before continued use.

Frequently Asked Questions

Is a boiler efficiency check the same as a boiler service?
It overlaps with a routine service, but the emphasis is on measuring performance and identifying energy waste. You will get results and recommendations aimed at improving efficiency as well as confirming safe operation.
How often should I book a boiler efficiency check?
For most homes and rentals, once a year is a sensible interval, often alongside annual servicing. If you notice higher bills, inconsistent heating or frequent resets, it is worth booking sooner.
Will an efficiency check reduce my gas or oil bills?
It can, especially if poor combustion, incorrect settings, dirty components or system issues are found. The check helps pinpoint what is limiting performance so you only spend money on changes that make a measurable difference.
Do you check combi, system and regular boilers?
Yes, the checks are tailored to the boiler type and how it integrates with your heating system. Gas and oil testing must be completed by an appropriately qualified engineer.
What if you find a fault during the check?
You will be told what the fault means, how urgent it is, and what options you have to fix it. If there is a safety concern, you will be advised not to use the appliance until the issue is made safe.
