In case there are still people without gas, my neighbour has checked and has confirmed that ALL of the estate should have gas.
He explained that Gordon (and others who still have a problem) need to go outside and locate where the gas pipe enters their property. There are two taps, one of which is on the circular gas regulator. That is the one to turn on and off a couple of times to get the gas flowing back through the pipe into the house.
Hopefully, if Gordon does this he will hot water and heating again.
