Boiler Servicing

What is a boiler service?

A boiler service allows checks to be carried out to identify if there are problems that require attention as well as ensuring your boiler is running as efficiently as possible. Whilst not a legal requirement, it is recommended by manufacturers and Gas Safe that boilers are checked and serviced annually. 

During the service, Gas Safe engineers follow a comprehensive boiler service checklist to make sure everything has been checked and is working well. 

What happens during a boiler service?

Our qualified Gas Safe engineers have the expertise needed to provide you with a thorough boiler service. Conducting various tests and checks, we aim to ensure that your boiler is functioning effectively and efficiently.

Boiler service checklist

A typical boiler service checklist may include:

1. Visual inspection

The engineer will visually inspect the boiler, clean and adjust components as necessary, look for any signs of damage, and identify any signs of distress that are immediately visible.

2. Operation and control

Your boiler has a number of controls and safety devices that will be tested for correct operation. An engineer will check that all of the boiler functions are working correctly, should they be required.

3. Flue and combustion releases

Combustion readings will be taken and checked to ensure they are correct and at acceptable levels. The engineer will check the construction, termination and route of the flue (pipe from your boiler to the outside of your house). They will make sure there are no obstructions in the flue terminals and that the flue is safely fitted.

4. Clean the main boiler components

In some cases if felt necessary, the engineer may remove, inspect and clean the main components in the boiler to ensure they are fit for purpose and have no noticeable defects. This will occasionally include parts such as the main burner, heat exchanger, flue ways and ignition pins. Such works are not usually required annually but instead at certain intervals and additional servicing costing is applied. 

5. Safety & Operational Checks

There are lots of tests to tick off during a boiler service checklist inspection.

These include:

  • Flame sense device and whether it operates correctly
  • Pilot burner and any cables and probes
  • High-limit thermostat
  • Boiler operation
  • Provision of adequate ventilation
  • Flue effectiveness
  • Heating controls
  • Electrical wiring connections
  • Location of the boiler and nearby combustible materials
  • Gas and pressure flow
  • Safety devices
  • Seals

6. Conduct a record

The engineer will undertake a series of tests and checks, making a record of each – this will include a record of the boiler pressure or heat input. As the homeowner, you’ll then be able to keep this information for future inspections or when problems arise.

7. Ensure the boiler is ready for use

At the end of a boiler service, the engineer will make sure the boiler is working well or flag issues found during servicing. 

While the seven steps above are how we conduct most boiler services, there are additional checks depending on the boiler type you have. For example, if you have a condensing boiler, we’ll also check the drainage system of the boiler.

Boiler Service Reminders
We are set up with plumbing and heating specific software which instantly diarises future boiler service due dates. If requested, this allows us to send you reminders via email and/or in the post. 

With our plumbing and heating software, we are also able to store your appliance details and job records for reference should this information be required at a later date.
