What Is Kitchen Second Fix?
Kitchen second fix is the second phase of plumbing and electrical work, carried out after the kitchen units and worktops are installed. It includes final connection of the sink, tap, dishwasher and appliances to services that were roughed in during first fix.
First Fix vs Second Fix
First fix plumbing and electrical work happens before the kitchen is installed — running pipes and cables to the approximate positions of future appliances and fittings. Second fix happens after the kitchen is in: connecting those pipes and cables to the actual sink, appliances and outlets.
