Retrofit assessments play a vital role in the government-approved PAS 2035 process for decarbonising UK homes.

Our experienced local team has worked hard to become award-winning retrofit assessment providers for PAS 2035 projects across the nation and provide an unrivalled approach to speed, quality, and customer care.

Delivering PAS 2035 retrofit assessments at scale for social housing organisations and local councils requires speed, accuracy, and the ability to collaborate with multiple stakeholders. From Kent coastal towns to Cornish cottages and high-rise flats in Stoke, we have undertaken thousands of residential assessments to inform scores of retrofit projects.

Why work with us?


Our retrofit reports have been optimised over time and through countless iterations based on feedback from Retrofit Coordinators.

They now represent the high bar for data collection and detail in the industry.


We were Highly Commended as an Employer and honoured with Retrofit Assessor of the Year awards at the Retrofit Academy Awards ceremony in 2023.

The judges praised us for our ability to combine exceptional quality with the ability to work at scale.


Our combined team of retrofit assessors and office-based staff work collaboratively to turn around a high number of high-quality reports each week.

We focus on speed, accuracy, and scale when planning large-scale PAS 2035 retrofit assessment projects.


Our rate card prices for all services are reviewed regularly, so we’re confident that you won’t find a better service for a better price anywhere else.

If you think you’ve found one, we’ll either beat or match it.


Navigating the complexity of energy efficiency, decarbonisation, and building regulation updates isn’t easy. We’ve worked hard to explain a range of topics related to retrofit in plain English to help non-experts get the information they need.
