tbh we were in the same boat last year.
we had no hot water or heating when we bought our house and it needed rewiring.
new radiators , new boiler, Gave up 2 weekends to run the pipe work and rads + boiler and remove the old stuff.
Got a man in to do the boiler. - in august, was cutting it fine really for the winter - lucky it all worked
then we rewired it in a week during my christmas holidays.
again got a man in to do the fuse board and testing.
saved us about 6 grand.
Now its coming up to time to do the kitchen , i need to get a structural engineer in to do some drawings and calcs for a beam but till ive saved up enough we will just have to live with the crappy kitchen..
Im surprised , was your old kitchen really that bad that it needed to be torn out or what made you agree to change it ? seems mad as a tennent to pay for that but i guess your hoping it will lead to them staying long term ?
