Sized Right, Fitted Properly

A radiator that’s too small for the room will never heat it properly, no matter how good your boiler is. We calculate the correct output (BTU) for each room before recommending a replacement, rather than fitting a like-for-like swap that was never right in the first place.

Whether it’s one cold radiator or a full-house replacement, we can coordinate the work alongside any wider central heating changes you’re planning.

Is It Time to Replace Your Radiators?

Cold spots at the top or bottom of a radiator, one room that never quite heats up, or radiators that need bleeding constantly are all signs worth checking. Sometimes it’s a simple fix like a power flush; other times the radiator itself is undersized or corroded internally.

If sludge is the underlying cause, a power flush often solves it without needing new radiators at all. We’ll diagnose before recommending a replacement.

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.

 Trustindex verifies that the original source of the review is Google. 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.

 Trustindex verifies that the original source of the review is Google. 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.
