Radiator Installation Expert
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.
Radiator Installation Guide
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.
COMMON WARNING SIGNS
The same careful workmanship, whether it’s a family home in St Albans or a busy premises in Hertfordshire.
Constant repairs could mean it's time to replace your boiler.
Older boilers are often less efficient and more expensive to run.
Cold radiators or inconsistent temperatures may indicate your boiler is struggling.
Banging, whistling or gurgling sounds shouldn't be ignored.
Leaks around your boiler can lead to further damage if left untreated.
If your boiler is over 10–15 years old, replacing it may be more cost-effective than repairing it.

We calculate the correct heat output (BTU) for each room based on its size, insulation and window area, rather than just matching what was there before.
Yes. Single radiator replacements are common and usually completed within a few hours without disrupting the rest of the system.
Usually trapped air, which is a quick fix. Cold at the bottom instead often points to sludge, which may need a power flush rather than a new radiator.
Not necessarily. A correctly sized radiator often runs more efficiently than an undersized one working harder to heat the same room.
In most cases yes, giving you room-by-room control without replacing the radiators themselves.
