I can't find how to turn off my water mains/supply

If you're on a water meter then your meter will act as an external stop tap. This is usually located in the footpath or within your boundary. Your water meter serial number is located on your bill.

This can also be done if you have an internal meter, usually found either in the kitchen, utility room, airing cupboard or bathroom.

If you don't have a water meter you can complete this using the internal stop tap again found in the places above.
