PAS 2035 Retrofit Standards

Structured retrofit advice to support compliant, well-coordinated energy efficiency improvements

Independent PAS 2035 support to help deliver compliant, high-quality retrofit projects.

MES Building Solutions provides professional support aligned with the PAS 2035 framework, helping clients deliver domestic retrofit projects that are compliant, coordinated, and technically sound. Our services support the assessment and design stages of retrofit, ensuring measures are appropriate to the building, risk-led, and integrated with wider project objectives.

PAS 2035 establishes a whole-dwelling, fabric-first approach to retrofit, requiring careful consideration of building condition, occupancy, ventilation, and overheating risk. We work collaboratively with project teams to support informed decision-making and reduce technical and compliance risk throughout the retrofit process.

Our advice is proportionate, practical, and clearly documented, supporting funder requirements, quality assurance, and successful scheme delivery.
