We help organisations across the UK understand their responsibilities, identify compliance gaps and prepare the documentation needed for successful retrofit delivery — across PAS 2035, ECO4, Building Regulations, TrustMark and related quality assurance.
Retrofit projects involve several overlapping standards, funding conditions and regulatory requirements. Missing one element can create problems later — especially when documentation is reviewed by funders, certification bodies or quality-assurance teams. Effective compliance management can help:
Compliance should not be a final-stage paperwork exercise — it needs to be integrated into assessment, design, installation, monitoring and project management from the start.

PAS 2035 provides a structured process for managing domestic energy retrofit. Our consultants review your project against relevant PAS 2035 requirements and help your team understand what evidence, controls and processes may be required — supporting assessment, design, installation and post-installation stages. A review may cover:
A structured approach also makes it easier for project managers, coordinators, designers and installers to understand their responsibilities throughout the process.

Projects delivered through the Energy Company Obligation may need to satisfy specific scheme requirements as well as relevant retrofit standards. Our consultants review your project documentation and processes against the requirements relevant to your ECO4 work, checking:
For organisations managing multiple properties, a consistent compliance framework standardises documentation and quality checks — and helps identify problems before they become costly.

Practical guidance across the standards, scheme conditions and quality-assurance processes that shape compliant UK retrofit delivery.




A practical process designed to make compliance easier to manage from first consultation to audit readiness.

We translate technical standards, documentation and responsibilities into a practical compliance process your team can follow.
We identify gaps, explain requirements clearly and help you establish suitable project controls.
Compliance managed throughout the project — not left until completion to discover missing evidence.
