Fix the real cause, not just the symptom
Room-by-room clues matter
Knowing which radiators or rooms are affected helps narrow the fault down faster.
Repairs guided by diagnosis
The right solution depends on the failed part, not the loudest symptom in the house.
Checked after the repair
We test circulation, pressure and controls, so the repair result is properly confirmed.

Finding the fault across the full heating system
Cold radiators, pressure loss, leaking parts, noisy pipework and controls that seem to ignore you can all point to faults away from the boiler itself. We trace the problem through the parts that move heat around the property, following the signs through pumps, valves, thermostats, radiators, pipework and the boiler connection until the cause becomes clear. That matters because the right fix depends on where the fault sits and what is actually failing. With Hereward Gas Ltd, the job starts with diagnosis rather than a hopeful change of parts.
Repairs matched to the part that has failed
Once the cause is identified, the repair depends on the failed or worn component and how it affects the rest of the system. Some faults sit with circulation, some with pressure stability, and some with controls or leaks in a specific area. After the repair, a visit from Hereward Gas Ltd includes checks on circulation, pressure, radiator performance and response to heating controls, so you know the system is behaving properly again. Before we attend, it helps to say which rooms are affected, what has changed recently and whether the fault keeps returning.

Frequently asked questions
Why are some radiators cold while others heat up?
That can point to circulation issues, balancing problems, a faulty valve or another fault elsewhere in the system. We trace the problem across the heating setup to find why heat is not being distributed properly.
What details help with central heating fault diagnosis?
Tell us which rooms or radiators are affected, whether pressure drops, if there are noises in the pipework, and whether anything changed recently. Those details help us narrow the fault down before and during the visit.
Do you test the system after repairs?
Yes. We check circulation, pressure stability, radiator performance and response to the controls before we leave. With Hereward Gas Ltd, the repair is confirmed by how the whole heating system behaves, not just by changing one part.
