Why paperwork matters
Buyers and solicitors connect guarantees to insurability and to whether works were completed competently. Missing paperwork often becomes an enquiry thread.
Practical seller list
- Heating system service history and warranty.
- Window and door guarantees where installed.
- Electrical and roof works evidence where relevant.
Honest gaps
If something truly cannot be found, say so early and discuss with your solicitor rather than hoping it never comes up.
