Boiler Servicing Expert

A Service That Actually Checks Everything

A boiler service is a full safety and efficiency check, not just a quick look. We test the flue, check gas pressure, inspect the heat exchanger and confirm the safety devices are working correctly, then leave you with a written report.

Most manufacturers require an annual service to keep the warranty valid, and it’s the easiest way to catch a small fault before it becomes a costly repair or a mid-winter breakdown.

Boiler Servicing Guide

Is It Time to Book Your Annual Service?

Most manufacturers recommend servicing every 12 months, ideally before winter when the boiler works hardest. If it’s been longer than a year, your warranty may already be at risk, since most providers ask for proof of an annual service to keep it valid.

A service also picks up early signs of wear, like a struggling pump or a dropping efficiency reading, well before they turn into a breakdown that leaves you without heating.

COMMON WARNING SIGNS

Don't Ignore These Signs

Book a check if you notice any of these. Most problems are quicker and cheaper to fix when they are caught early.

Frequent Breakdowns

Constant repairs could mean it's time to replace your boiler.

Higher Energy Bills

Older boilers are often less efficient and more expensive to run.

Uneven Heating

Cold radiators or inconsistent temperatures may indicate your boiler is struggling.

Strange Noises

Banging, whistling or gurgling sounds shouldn't be ignored.

Water Leaks

Leaks around your boiler can lead to further damage if left untreated.

Old Boiler

If your boiler is over 10–15 years old, replacing it may be more cost-effective than repairing it.

Sharif bhai did a very good job in my property. He fitted the shower properly and fixed the leak issue. He checked everything carefully and made sure there was no more leaking after the work finished. He was polite, professional, and helpful. The work was neat and clean, and the shower is now working very well. I am happy with his service and I would recommend Sharif bhai to others for plumbing work.

I recently had my boiler serviced by Heatgap( 99 Byron Road,Luton) and I couldn’t be happier with the experience. The Technician arrived on time, was professional, and explained everything clearly. The service was thorough, and they made sure the boiler was running safely and efficiently before leaving. What really stood out was their friendly attitude and attention to detail. They took the time to answer my questions and gave helpful advice on maintaining the boiler. Overall, excellent service from start to finish. I would definitely recommend Heatgap to anyone looking for reliable and professional boiler servicing.
