We benchmarked our fees against every major London architectural practice. The numbers below are roughly 30% below what you'd pay an architect for the same planning and building control outcomes — because we're chartered technologists, not the RIBA practice upstairs.
Straightforward single-service work.
The full picture — planning to site-ready.
Complex, listed, conservation or developer.

Retrieved 1 September 2026. Statutory fees do not vary between boroughs. Listed building consent carries no fee, and a resubmission within twelve months of a decision on the same site is normally free once.
