• If your bath, sink or toilet is blocked, you’ll need to follow the instructions here to clear it.Blockages are normally caused by a build-up of things like fat, tea leaves and hair or because things have been put down the toilet that don’t belong, such as the plastic toilet cleaners, disposable nappies or toys. But if more than one of your rooms has a blockage (say your bathroom and your kitchen) you might have a problem further down in the sewage pipes or drainage system. If this is the case you’ll need to call us. The numbers are here.
