Right thanks for all the advice guys, had all the quotes etc done now, and as a result exchanged contracts and got the keys
The gas, boiler etc is fine and should be so for another decade or so at least.
The electrician has quoted me £850 for smoke alarms, extractor fan, rewiring of fuse board, replacing all light switches, fixtures and plug sockets etc.
The plumber has quoted me £250 to repair the kitchen sink, replace the drain and plumb in a power shower.
The plasterer has quoted me £100 a day + materials, saying it will take no more than 2 days to fix all the damp damage and re-skim a few walls. He will also be damp proofing the area with a cheap tar like substance to prevent it recurring. Although it looks like what has happened is that the previous owner had the walls re-plastered, then painted straight over, thus the damage.
Electrician is in today getting on with the work, so in about a month it should be ready (Well that’s because plaster takes 3 - 4 weeks to dry, al the work will be done by the end of next week)
