Method. Every figure is derived, not surveyed. Sumitt’s 2026 regional rate cards price the reference scope shown under each job, with the same takeoff engine the app quotes with. Each rate is then set so the margin is a share of the price, not a markup on cost. The first eleven trades were recalibrated in July 2026 against named supplier prices. Carpentry, roofing, bricklaying and rendering were calibrated when they were added in August 2026, and formwork when it was added in September 2026. All figures ex GST. The regional spread uses the same rate cards’ material and labour factors. No AI, no user data, and nothing here reflects what any Sumitt user charges.
These are the current edition’s figures. The edition and the day it was published are on the index. Rates are a guide for your own pricing, not gospel and not advice. Your costs are the ones that matter, and every number stays editable in Sumitt.
