Build-pricing platform. Compared like-for-like: pricing, MCIAT credentials, approval rates, scope.
BuildPartner is a credible alternative for some project types; get a quote from both and compare.
BuildPartner operates as a build-cost estimating platform. Which suits you depends on whether you want a defined drawing package at a known price or a broader service.
A platform that estimates construction costs for residential projects from a specification, aimed at homeowners pricing a build before appointing a contractor.
Where that model is strong: Useful early, because a realistic build budget should drive the design rather than follow it.
What to establish before you commit: A cost estimate is not a drawing package. You will still need a measured survey, planning drawings, building regulations drawings and structural calculations from a designer and an engineer.
Every figure below is on our pricing page and does not change with the size of your build. We do not quote a percentage of build cost, because it gives a designer an interest in a larger build.

The same ten questions work on either side, and the answers are what actually separate one quote from another.
Statutory fees go to the council, not the designer, and they are set nationally for England. No practice can discount them, so they should appear in every budget identically.

We publish this comparison because homeowners ask for it. We describe BuildPartner by its business model rather than asserting its current fees or performance — ask them directly and compare the answers against ours. Statutory figures are the England rates in force in 2026 under the Town and Country Planning (Fees for Applications) (England) Regulations.
