Compliance requirements can be complex, and the guidance is not always straightforward. We help clients understand what is required, what is not, and how to keep the project moving with clear, practical advice.
Qualified and accredited
Accredited assessors working to current UK standards, Building Regulations and scheme requirements.
Practical, not just compliant
Plain-English advice you can act on, what needs to happen, when, and why it matters for the project.
One coordinated point of contact
Energy, sustainability, EPC and testing requirements coordinated through one clear point of contact, so nothing falls between separate suppliers.
Tailored support
One-off reports, project-wide coordination or retained portfolio support, shaped around how you work.
UK wide
We work with clients across the UK, on single properties and national portfolios alike.
Clear deliverables
Every report, calculation and certificate produced to a consistent standard and easy to hand on.
Start where you are in the project.
Most clients arrive because a council, building control officer, architect or consultant has asked for something specific. Choose the stage that best matches where your project is now, and we’ll help identify the reports, calculations, testing or certification likely to be needed next.
Feasibility
Early advice to understand site constraints, planning risks and likely compliance requirements before the project moves too far forward.
Feasibility and early strategy →Planning
Support for planning submissions where the local authority requires clear evidence, reports or assessments before approval.
Planning-stage reports →Technical Design
Calculations and technical evidence to support building control, design development and project compliance.
SAP, SBEM and building control calculations →Completion
