I got up yesterday morning to a very cold house and the boiler not working. Raynaud's nightmare, and of course we're deep in snow with icy winds.
I have a service contract with British Gas, but every time I called I got as far as "If you can wait, please call later as we are prioritising vulnerable customers" before the line went dead. I went online and the website crashed. Over and over.
My son ( in London) tweeted BG for four hours before getting a response. Meanwhile I hit the jackpot with a friend's husband who was able to get to me to fix the condensate (?) pipe which had frozen.
Moral of the tale is: keep an emergency survival blanket in the house, check that the back up electric fan is powerful enough and don't bother shelling out to British Gas, who seem to have no way of differentiating between vulnerable and non vulnerable customers. Count your fingers and toes regularly while counting the blessing of a builder friend.
