Guide to tolerances, materials and workmanship in new residential construction 2015

Under the new consumer protection measures introduced 1 January 2015, a 12-month defect repair period starts when new residential building work has been practically completed. During this time it is the contractors’ responsibility to fix any defects or to prove that any defective building work is through no fault of their own, their subcontractors’, or the products used if there is a dispute.

The government has published a guide to help homeowners and contractors understand and agree on acceptable levels of tolerances, materials and workmanship.
