We've owned three properties over 28 years.
Flat for two years - nothing as fairly new
Second home, lived there 15 years:
Brand new heating system installed
New boiler (turned out initial Ideal boiler, was far from Ideal!!)
New bathroom
New kitchen
New carpets, flooring
Replacing fuses with trip switch board
Current home, lived here 10 years (refurbished 14 years ago):
New roof next month.
New bathroom in autumn, looks tatty, a very minor toilet leak which three plumbers can't find and water probably running down behind tiles from leaking roof!
When funds permit, it'll be a new kitchen unless boiler goes beforehand
New flooring
(luckily wiring in only as done 14 years ago)
