Our Retrofit Approach
We follow a structured, PAS-aligned methodology, guiding projects from initial assessment through to delivery and performance monitoring. Retrofit is not just about installing measures.
It’s about designing the right solution for the building, ensuring long-term performance, compliance, and value. PAS 2035 provides the UK framework for whole-house retrofit, covering assessment, design, installation and monitoring of energy improvements.

How We Deliver Retrofit
Our approach ensures every project is planned, coordinated, and delivered to achieve long-term building performance and compliance.
Structured
Assessments
We begin with detailed assessments to understand building performance, risks, and the most effective retrofit measures.
Compliant
Design
All solutions are developed in line with PAS standards, ensuring performance, compliance, and long-term reliability.
Fabric-First
Approach
Energy improvements can increase a property’s EPC rating and support compliance with modern energy standards.
End-to-End
Delivery
From planning to implementation, we ensure projects are coordinated, scalable, and delivered to the highest standard.
Design & Planning
Our team develops compliant retrofit designs, aligned with project requirements, funding criteria, and building performance goals.

-
PAS-compliant retrofit design
-
Improvement option evaluation
-
Medium-term retrofit planning
-
Integration with insulation, heating and renewables​​
​
We take a structured approach to design and planning, ensuring each project is technically sound, financially viable, and ready for delivery at scale. This includes evaluating the most effective combination of measures while maintaining compliance with PAS standards and funding frameworks.
Quantity Surveying
Our quantity surveying services ensure projects are financially controlled, commercially viable, and delivered efficiently from start to finish. We manage costs, procurement, and contract administration, providing accurate forecasting and ongoing cost monitoring throughout the project lifecycle. By aligning budgets with project requirements and delivery timelines, we help minimise risk, maintain value, and ensure projects are completed within scope and cost expectations.
