Great work guys! Really exceeded my expectations! Wonderful – hope to work with you again very soon!

Nicolette le Roux – Workstream Construction

Yarlington Housing Group approached IRT Surveys because they offered a unique service for assessing our housing assets using infra-red thermography and because there was limited data around the quality of the wall insulation of our properties. IRT helped us by thermally surveying our entire stock and integrating the information into a comprehensive database which we are incorporating into our new 2020 Fuel Poverty Plan. We are able to interact with the database using their online tools in order to answer the ‘what if’ questions when considering fabric alterations. One thing I liked was their ability to quickly understand our requirements and to deliver the project on time and to budget. I found the experience positive and engaging; IRT did a brilliant job of carrying out a comprehensive thermal image stock survey which provided an actual picture of our stock portfolio’s thermal performance.

Julian Scott – Yarlington HA
