How we rank

Before you hire

Several of these trades are regulated: plumbers must be registered with the Plumbers, Gasfitters and Drainlayers Board, electrical work must be done by a registered electrician on the Electrical Workers Registration Board register, and only NZRAB-registered architects can use the title Architect. For a builder, check their Licensed Building Practitioner number on the MBIE register. Get at least three written quotes that itemise each trade, and ask for references or photos of comparable recent jobs. Ask what written warranty covers both materials and workmanship.
