About
Intelligence for the buildings we already have.
BuildGrade Ltd, London, incorporated 2026. Building-stock intelligence for the teams delivering retrofit.
Mission
Our mission is to make every retrofit decision in the UK start from the same evidence: what each building is, how it performs, and what will change it.
How we work
Our principles.
02
Precise
Building-level, not postcode-level; reconciled to the GLA London Building Stock Model.
03
Actionable
Outputs are priorities and measures, not dashboards.
04
Open
Built on open data standards and designed to integrate, not lock in.
