Boiler Servicing

What our boiler service includes

Every annual visit follows the manufacturer's recommended checks:

Burner and pilot inspection

Combustion test

Safety control testing

Pressure check

User controls check

Condensate check

Flue condition, plus a flue and carbon monoxide test

Visual check for leaks and corrosion

Readings recorded

Worn parts noted

What you get afterwards

You get a written service record to keep for warranty purposes, any safety recommendations, and plain advice on repairs, parts or a cover plan if you need one. Parts showing wear are noted, so you can plan for them rather than face an unexpected breakdown.

Commercial and landlord boiler servicing

We service light-commercial boilers as well as domestic ones, and tailor each visit to the plant on your site.

For landlords and small businesses, the paperwork matters as much as the work. After each service you receive a written service record with the readings taken, any safety notes, and the parts showing wear noted ahead of time so you can budget for them. It gives you a clear record to keep on file for your property or premises.

If you let a property, a service is not the same as your yearly landlord gas safety record. That is a separate legal check, covered on our Gas Safety Checks page.

For larger heating systems, planned maintenance and installations, see Commercial Heating Services. If a commercial boiler has broken down, our Commercial Boiler Repair Services page explains how we handle faults.

What affects the cost of a boiler service

The price of a service depends on a few things:

Make and age of the boiler. Older or less common boilers can take longer to strip down, clean and test.

Access. A boiler in a loft or a tight cupboard takes longer to work on than one on a kitchen wall.

Domestic or commercial. A commercial boiler usually needs more checks and fuller paperwork than a home boiler.

Tell us the make and model of your boiler and where it is fitted when you get in touch, and we can give you a price for your service.
