Retrofit Design
Retrofit Services
A Retrofit Designer is responsible for translating assessment data into a clear, effective plan for improving a home’s energy performance. Working within the PAS 2035 framework, they ensure that all proposed measures are technically sound, appropriate to the building, and designed for long-term success.
Before creating the design, the Retrofit Designer must have access to a full Retrofit Assessment, carried out by a qualified assessor. Based on this data, the designer develops a specification that outlines energy efficiency measures (EEMs) tailored to the property.
Delivering successful retrofit is as much a design challenge as it is a technical one.
To explore this in more depth, we have made a focused on-demand webinar available, drawing on real-world experience from External Wall Insulation delivery and whole-house retrofit programmes.
The session looks at why retrofit outcomes are shaped at the design stage, how early decisions influence risk and performance, and what good, design-led retrofit looks like in practice.
It is a practical discussion grounded in live delivery experience, rather than theory or compliance alone.
A strong retrofit design ensures every upgrade is targeted, effective, and built to last – reducing risk, improving outcomes, and delivering real energy savings.
Retrofit Designers are responsible for translating assessment data into real-world solutions that work for the property, its occupants, and long-term energy goals..
Their role includes:
With a balance of technical expertise and real-world understanding, Retrofit Designers ensure each solution is fit for purpose, compliant with PAS 2035, and built to deliver meaningful results.
