A drop in pressure

If your boiler pressure drops, it can prevent your heating from working adequately. If you see a leak, you will need to contact an engineer to see if a part needs replacing. Otherwise, you can try to repressurise the boiler if you know how.


A leaking boiler should always be checked by a registered engineer to determine the problem. The pressure valve or pump seal may need replacing; if the pipes are the source of the leak, it could be an issue with your boiler’s installation or even corrosion of the pipes. A regular boiler service should always be done to prevent a big issue from occurring.

No hot water or heat

Although it may seem like a big problem at first, losing your hot water or heat can be as simple as checking your boiler pressure or making sure that your thermostat is set correctly. If these are not the cause of the issue, you may need to call out an engineer to check for a faulty airlock or valve.

Strange noises

If your boiler is banging or whistling, it could signify several problems. Excess air, kettling and a pump failure are just a few of the reasons, so if you have checked the pressure and bled your radiators, it may be time for an engineer to visit. If there is a serious problem, a new boiler may be required, so it is important to do your research to find what will work best for you.
