Retrofit
Retrofit solutions that scale, from strategic planning to on-site delivery
We deliver retrofit solutions that are practical, scalable, and built on deep technical expertise. Working across the entire project lifecycle, we help housing providers decarbonise their stock, improve energy performance, and align with both regulatory standards and net zero ambitions.
Retrofit is a complex and evolving space, but we know how to navigate it. With our blend of PAS 2035 compliance, robust project management, and resident-focused delivery, we take the stress out of scaling retrofit and turn bold sustainability goals into measurable impact.
What we do
Our trained and qualified assessors complete detailed evaluations of individual homes in line with PAS 2035 requirements. This includes assessing condition, occupancy, and energy use to develop accurate improvement strategies that reflect each property’s context and constraints.
Acting as the central point of accountability, our Retrofit Coordinators ensure that every project adheres to the PAS 2035 framework. We manage risk, maintain quality standards, and ensure that the retrofit journey remains joined-up from start to finish.
Our experienced team manages retrofit programmes at scale, ensuring procurement, delivery, and stakeholder coordination are aligned to your objectives and timelines. We provide transparent governance and real-time reporting throughout.
We bring commercial insight to retrofit by delivering clear cost planning, benchmarking, and value engineering at every stage. Our team helps you manage budgets effectively and avoid unexpected costs.
We provide technical inspections and audits throughout design and delivery to ensure works meet quality and compliance standards. Our approach reduces defects, supports contractor performance, and protects your investment.
We assess property portfolios to identify risk, opportunity, and suitable retrofit measures across archetypes. This helps align retrofit with long-term investment plans and funding windows.
From early consultation to post-works support, we help landlords communicate clearly with residents. We support behaviour change and satisfaction through educational materials, events, and direct engagement.
After project completion, we assess retrofit performance against expected outcomes. This includes monitoring data, occupant feedback, and lessons learned to inform future strategies.
We provide retrofit input into wider strategies, toolkits, and national programmes. Our team supports clients and partners through specialist studies, innovation pilots, and industry engagement. Download the Retrofit at Scale Toolkit
