Warranties and Certificates at Completion: Developer Discipline

Completion is a milestone, not the end of paperwork

Buyers need to insure, maintain, and sometimes prove what was installed. Certificates for heating, electrical work, and warranties matter for years, not days.

Resale asks the same questions again

Future buyers’ conveyancers will request evidence again. If your handover is clean, you reduce pain for the first owner and protect your reputation when they sell.

Storage and versioning

Avoid “final v2 really final” attachment chaos. Use dated files and a clear index. If you update a document for a plot, make sure downstream holders can access the latest version under the right permissions.

Caveats

This is not legal advice on what a specific lender requires. Buyers should follow their solicitor and lender.
