Our products
Compliance software built and run by BRS Technology. Each one takes a slow, expensive part of Building Regulations and makes it fast enough to use during design.

Prove Part O compliance without the guesswork. autoTHERMAL will run both Approved Document O routes, the Simplified Method and full CIBSE TM59 dynamic thermal modelling, in one browser-based tool.
- Both Part O routes
- TM59 Criteria A & B
- Audit-ready reports
Part L photographic evidence
Effortlessly achieve Part L evidence compliance. autoBREL replaces manual processes, shared drives and email chains with one guided photographic evidence app.
