Thermal imaging

Find out where your home is leaking heat

What is thermal imaging?

Thermal imaging can vividly reveal where your home is leaking heat.    The cameras are sensitive to infra-red and make ‘temperature map’ images .    This can show problems with insulation, draughts, damp and more –  useful in older homes, but also for revealing defects in new-builds. The images are easiest to decipher when it’s at least 10°C warmer inside than out, so this is mainly a winter activity.

Some of the problems shown are easy for householders to fix, like draught-proofing, and some, like faulty insulation, may need professional help. Significant improvements in comfort, energy bills and carbon emissions are often made as a result. More in this 2-page report.

Training & camera loan scheme

Come to a short training session to learn how to use our thermal cameras and interpret their images – then you can borrow a camera to survey your home, those of friends or family and (we hope) others in your neighbourhood. It’s great to see your home in a new light and it provides good motivation to fix any problems that are revealed. More in this 2-page report.

Book a camera

Normal bookings are closed till November, or maybe late October, if it’s cold.

We lend cameras for free to people already trained to use them and , more importantly, to interpret the images.
In the meantime, if you want to borrow a camera to checkout why your home/a home is hot during a heatwave, please email: 

We are currently unable to offer surveys. If you want a survey, come to a training session, or if that’s not your thing, perhaps you can persuade a friend to get trained and then survey your home?
