Burst pipe, no heating, water coming through a ceiling. Ring me and I will talk you through making it safe while I am on my way.
Find your stopcock, usually under the kitchen sink, and turn the water off. If water is near lights or sockets, kill the power to that circuit. Put a bucket under the worst of it and open a tap downstairs to drain the system.
If you can smell gas, ring the National Gas Emergency Service on 0800 111 999 first, then ring me.
Call outs are £80 for the first hour and £30 for every hour after that. If parts are needed I tell you before I fit them. No meter running quietly in the background.
Tell me what you need and I will come and look at it. You get the price before I start.
