Do it yourself

The first thing to check is where the radiator is cold, as this will help you to determine what the problem might be. Is it just cold at the top, just the bottom, or is it all over?

If it is the top that remains cold, there is likely to be some air trapped in the system. This is a common problem and can be resolved by bleeding the radiator to remove the air.

The bottom of the radiator being cold can signify a build-up of debris in one or more radiators. Again, it is quite straightforward to remove the build-up, but it can be a fiddly and messy job.

You should be able to add your boiler to your policy for a small additional charge or take out emergency cover specifically for your boiler and heating system.
