Why is my radiator cold

So the answer can vary quite a bit.

Firstly are the valves either side open? Remember rotate left for open and right for closed.

Secondly there may be a blockage in the pipes, we have thermal imaging tools that help us assess this.

Thirdly if you have a thermostatic radiator valve (TRV) fitted it may well have seized into position, if this is the case this is a short term fix but be warned we take no responsibility if the pin pulls out or a leak starts, this is oily upto you to do. You ultimately need a new TRV.
