Boiler Servicing

Boiler Service After Installation

A boiler service after installation is the first planned maintenance visit for a newly fitted boiler. It confirms safe, correct operation, checks efficiency, and creates a clear service record that can support warranty requirements and future servicing.

More information

What the post-install boiler service covers

This visit focuses on verifying performance, safety and reliability once the boiler has been in normal use.

  • Visual inspection of the boiler, pipework, flue and termination
  • Safety checks on seals, ventilation and combustion performance
  • Combustion analysis and necessary adjustments within manufacturer limits
  • Inspection of key components (burner, heat exchanger area, fan, pump where accessible)
  • Cleaning of parts where required and permitted
  • Checks on system pressure, expansion vessel charge and condensate route
  • Testing of controls, thermostats and safety cut-outs
  • Confirmation of correct hot water and heating operation
  • Service record updated with readings and observations

Who this service is for

  • Homeowners who want reassurance their new boiler is running safely and efficiently.
  • Landlords who need a documented maintenance trail alongside their ongoing compliance duties.
  • Small commercial sites that rely on consistent heating and hot water with minimal downtime.
  • Anyone noticing early issues after installation, such as unusual noise, fluctuating pressure, or inconsistent heating.

How the visit works

An appropriately qualified engineer will carry out checks specific to your boiler type (Gas Safe for gas boilers, OFTEC for oil where applicable). The boiler is inspected, tested and measured, with combustion readings taken where required. If minor adjustments are needed, these are made in line with the manufacturer’s instructions, and findings are recorded.

What happens after the service

You receive a clear summary of what was checked and any recommendations to protect performance and reliability. If any developing issues are spotted, you will be advised on next steps before they become faults. You can then keep to an annual servicing schedule for ongoing efficiency and warranty support.

Frequently Asked Questions

When should I book the first service after a new boiler installation?
In most cases, it is due within the first 12 months, but the exact timing depends on the manufacturer’s guidance. If you have concerns about performance soon after installation, it can be checked earlier.
Will a boiler service after installation help protect the warranty?
Many manufacturers require servicing at specified intervals and a record of the work. This service provides documented checks and readings that can support warranty compliance, subject to the warranty terms.
Is this the same as commissioning a new boiler?
No. Commissioning is the initial set-up and safety verification carried out at installation. The post-install service is the first planned maintenance check after the boiler has been running in everyday use.
What do I need to have ready for the appointment?
Please have the boiler manual and any benchmark or commissioning paperwork available if you have it. Make sure the boiler, flue access points and controls are reachable, and let us know about any issues you have noticed.
Does a boiler service include a landlord Gas Safety Certificate?
A boiler service is maintenance and performance checking, not a Landlord Gas Safety Record (CP12). If you need a CP12, it can be arranged as a separate visit or combined where appropriate.
