What to do if you discover frozen pipes.
1. Turn off the water supply:
Turn off the main stop tap. You should find this under the kitchen sink or where the service pipe enters your home.
Turn off the stopcock in your cold water tank if you have one, it's usually found in the attic or loft.
2. Beat the burst:
Protect everything around the pipe that appears to be frozen to avoid damage if it bursts.
3. Thawing out:
Open the tap nearest to the part of the pipe you think is frozen so the water can flow through when it has melted.
Thaw the ice in the pipe with a hot water bottle or hairdryer (taking care to keep it well away from 
any water), beginning from the tap end and working back toward the cold water tank. Never use a heat gun or blow torch.
