Some renovation prices
Hi there, just in the middle of less significant renovating a 30 year old, 4 bed with (conv attic and garage) house, and here are some prices that might prove useful.
Rewire to include hardwired firealarms on 3 floors, replacement of old fuse board with modern trip swicth box, external plug, TV cable in two rooms, Phone points in 3 rooms, cost 7500. We didn't go overboard on the plugs, and would have included more in hindsight, so don't skimp on that.
Plumbing - replace gun barrel piping in central heating system with qualplex (sp?)/cooper, and convert to gas from oil, replace/add 4 rads, replace shower and shower door. Cost 7700.
Can't help with the rest, but hope this helps a little. Some hidden costs are plasterer to plaster the chased walls etc. around 300. Painting ceiling after plumbers leaked contents of old cylinder all over the upstairs 100. I'm sure there are more I haven't come across yet.
