We completely redecorated (bar the upstairs landing which is still unfinished two years on), stripped out and reinstalled the bathroom and the boiler (£3500 for the plumbing work, £800 on tiling and tiles, £500 on bath, sink, toilet, taps, shower screen etc), replaced all the windows and the front door (£2000 for 6 windows and £800 for the front door), changed the fuse box (necessary as it was dangerous and outdated - £400), hired skips (£200) etc. We had a budget of £14,000 and 6 weeks and we got it all done in that time before we moved in, completely ate through our budget. We needed a plasterer and also employed a roofer to check the roof thoroughly (I think the plastering was £300 and the roofer £200).Our property is a small three bed terraced house with a small bathroom and a large kitchen in Essex. We priced up a kitchen at about £2500 but ended up keeping the old one.
There are lots of small things left to do and we discovered lots of extra things once we had started pulling up carpets and removing the bath etc that added extra costs. Things that added up were the cost of tools and extra materials like paint, light fittings, light switches, plug sockets, carpets, laminate for downstairs, fridge/furniture, shelves, door handles, doors etc. Little things that also took a long time as well e.g. it took DH half a day to hang a door and another couple of hours to put on the handle, plug sockets take two hours or so, wall preparation took several days in the big lounge/ diner.
We went with a local window company rather than Everest or Anglian who did high pressure selling and then contacted us every few days to drop the price. They were very very good, as were the plumbers who were the most expensive quote but turned up everyday at 8am and worked solidly until 5pm. You need quotes and you need to plan like hell to make sure everything happens in the right order and nice and smoothly. You will also need some contingency if you discover any damp or wood worm or you discover some bodges by the previous owners (yes, yes and yes in our case, all of which were not picked up by the survey). Its really hard work but its lovely to see it all come together at the end.
