I've moved this to Legal Issues as it seems more suited there (chas49)
Something I came across in passing when renewing an insurance policy that may be well known – but not to me…
If, knowingly or otherwise, I have substandard work done on my house and then I sell it, caveat emptor does not apply, and it seems irrelevant whether or not I disclose the work to the buyer. This liability appears not to be time limited or limited even to my immediate sale (to the buyer who may in in due course turn sell the house on).
I was so surprised at this I went back to primary legislation: Defective Premises Act 1972 1972 Ch 35 section 3 “Duty of care with respect to work done on premises not abated by disposal of premises”
The duty of care may technically be due from my dodgy electrician or cowboy builder, but as their employer and house seller, I may be landed with carrying the can.
This is my reading; CK or other experts may well correct it!
