Got an emergency call out to Shankill yesterday. No sockets in the house were working, found a fault in the washing machine and restored power to the sockets. Then I got a call to Bayview in Killiney, central heating not working. The time switch on the central heating had gone faulty and was blowing the fuse. Luckily I had a new timer in the van and was able to get the central heating working for the customer.
