If you’re experiencing cold radiators even though your boiler is working normally, it’s likely that there’s a problem with your boiler pump or central heating controls.

The pump is faulty

If you suspect that the boiler pump is faulty you’ll need to contact your local heating engineer who will be able to repair or replace it.

The pump thermostat or timer is faulty

Double check that the thermostat or timer is working correctly. If you find a fault, contact your local heating engineer to arrange for a replacement to be installed.

There are air pockets in the system

If you suspect that there’s trapped air within your system, release it by bleeding your radiators.
