ConstructQS guide

Construction estimating software for UK & Ireland contractors

Construction estimating software for contractors in the UK and Ireland: build accurate quotes, bills of quantities and branded PDF tenders, with regional rate books and an AI QS assistant.

Construction estimating software takes the risk out of pricing a job. Instead of a spreadsheet that grows unwieldy and hides errors, you build a structured estimate: measured quantities, unit rates, and clear add-ons for preliminaries, overheads, contingency and profit. For contractors across the UK and Ireland, the right tool also handles the things a generic spreadsheet never will — pricing in pounds or euros, applying UK VAT at 20% (contact us for the Republic of Ireland rate), and adjusting the pricing profile to the sector you are working in.

Good estimating software is fast where speed matters and careful where accuracy matters. You should be able to turn a set of drawings or a scope of works into a costed estimate in a fraction of the time a manual take-off would need, then produce a clean, branded quotation your client can actually read. Behind that, every rate should be traceable to its source — your own rate, a supplier quote, a regional rate book, or a clearly-labelled AI estimate — so you always know what your tender is built on and never send a price you cannot defend.

ConstructQS is built for exactly this. It covers every sector, from private and social housing to commercial, industrial, healthcare, data centres, roads, bridges and utilities, and every trade from bricklaying and joinery to groundworks, steel and M&E. Regional rate books give you a starting library, your own rates take priority, and the built-in AI QS assistant reviews your estimate for omissions, unusual prices and thin margins before you commit.
