My mains water stopcock is not under my sink. Where can I find it?

All modern homes are required to be fitted with an inside and outside mains water stopcock, so don't worry if you can't find yours under the kitchen sink. Many properties have their mains water stopcock located in an airing cupboard, under the bathroom sink, in a utility cupboard, under floorboards by the front door, within a garage, cellar or behind a panel next to the boiler. Apartment buildings often share a mains water stopcock, so if you are having trouble finding yours why not ask your neighbours?
