Warranty and handover

When owners take over, they need to know whom to call. Agree a single contact and process in the contract, and give owners clear documents. A warranty nobody can find is worth little.

Detailed guidance

A warranty is only as good as its terms and its administration. Read what counts as a defect, how sag is measured, which exclusions apply and who can claim. Check whether the warranty is for a stated period from delivery or from handover, and whether it passes to unit owners.

Agree a simple claim process, with a named contact and a response time. Ask what evidence you must provide, such as photographs, and what remedy applies: repair, replacement or refund. Provide owners with a document that explains the process. Keep delivery and installation records. Revisit the warranty with the supplier if the project is phased, so that later phases get equal terms.

Worked example (illustrative figures)

A developer negotiates a warranty where sag deeper than 25 mm counts as a defect and claims go through a single phone number. It transfers the warranty document to owners at handover. Months later an owner reports sag and gets a quick replacement because the process was clear. The depth is illustrative.
