Carry out combustion, gas pressure and safety interlock tests using calibrated analysers and manufacturer diagnostic tools, plus clean components as needed.

03

Certificate and advice

Issue a written service certificate and provide clear, practical recommendations for repairs, parts replacement or improvements to efficiency.

Why Choose us for Boiler Service?

Gas Safe and Unvented qualified

All work is carried out by a Gas Safe registered engineer with Unvented cylinder qualification, protecting safety and compliance for your property.

25 years hands-on experience

Quarter of a century of servicing new builds and older systems across Northampton means accurate diagnostics and durable results.

Service certificate issued

A clear, dated service certificate is supplied after every visit to support manufacturer warranties and future maintenance records.

What the service includes, tailored to your boiler make and age: visual and combustion checks, flue and ventilation inspection, burner and heat exchanger cleaning where accessible, pressure and leak checks, safety device testing and system control verification. I use calibrated flue gas analysers and manufacturer diagnostic tools to ensure readings are accurate and compliant with Gas Safe guidance.

Why a proper service matters. Regular, equipment-led servicing keeps your boiler running efficiently and detects faults before they become breakdowns. A service certificate is issued on completion to keep warranties valid and provide a written record for insurance or landlord requirements. If you prefer a same-day response for a follow-on repair, I can advise on next steps and prioritise urgent faults.

Frequently Asked Questions

Most services take between 45 minutes and 90 minutes depending on the boiler type and accessibility. I allow extra time for older systems, unvented cylinders or where additional cleaning and diagnostic checks are needed.

I have used this company for many years and they are just simply the best that I know for boiler and plumbing services. Thank you again Mark, you are brilliant.

It is genuinely not very often that you come across a business that values great service over everything else. Mark's knowledge and understanding of our boiler and heating setup made the previous gentleman from British Gas who serviced our property seem like a novice/apprentice. I'm so glad we've found him. If you're on the fence I highly recommend Mark.
