I think my boiler condensate pipe is frozen, what should I do?

During prolonged periods of cold weather, it is possible for the (normally) white pipe leading from your boiler to an external drain to freeze.

The first sign of this is normally the boiler stopping working and presenting a fault code of EA (if Worcester) or L2 (if Ideal). Other symptoms include the boiler making a gurgling/bubbling noise.

If you suspect the condensate pipe is frozen, we do not recommend pouring boiling water on the pipe as this could be dangerous or might damage the pipework. Instead, pour warm water on the pipe if it is easily and safely accessible.
