However I am not a council tenant, after the first day I had all lights working and my electrician left me with a double socket wired straight out of the fuse box for tv, kettle etc. I had to put an extension reel to direct the electric where I wanted it.
You can ask them to leave you with some form of electricity at the end of each day. This may just be a socket like I had to plug a reel into.
I would have thought that they will not be allowed to leave you with NO electricity in your home. There maybe something in your tenancy agreement about it.
Other than that you could ask a neighbour to allow you to plug the extension reel into their socket and offer them a couple of quid to cover the extra electric. I'm sure if you explain and allow them the same privilege if they have a rewire done.
