Spot heat loss around your home with one of our FLIR thermal imaging cameras

FLIR Constantine

For years we have been loaning thermal cameras to customers completely free of charge to help them find draughts in their homes. Since the energy crisis, we have ramped up our scheme and have sent cameras to nearly 4,000 customers. This year, we are concentrating our efforts on our most vulnerable customers that need them the most.

Read on to find out how to use the camera, why we're lending them and how you can borrow one.

The scheme for winter 2023/24 has now closed. We have received an incredible amount of requests to borrow our thermal cameras and will focus on ensuring those customers have a chance to use these super handy piece of tech.

The waiting list for next winter is now open, if you'd like to borrow a camera next year. Head to the form to add yourself to the list.

What is the scheme?

We have a couple hundred FLIR thermal cameras that we lend to customers every winter. These nifty gadgets connect to smartphones to quickly spot where heat is either escaping or entering. The cameras work best in the winter when the weather is cold and draughts are easier to spot.

Have a closer look at one of the models we offer in the scheme, the FLIR ONE Edge Pro, to find out a little more about how they work and if your phone is compatible.

Why are we lending cameras?

We genuinely want to help our customers be more energy efficient. It's simply the right thing to do, not only because it keeps your bills low, but because it’s better for the environment as well.

We've sent our cameras out to nearly 5,000 customers over the last few years, and we’re absolutely honoured that so many customers have told us that the camera loan has helped them practically identify how to save heat in their home.

Right now, saving gas is more important than ever, with millions of UK households left struggling to pay record high energy bills.

For Winter 2022, we’ve prioritised camera loans for those who need it most.

How do I apply to borrow a thermal camera?


Our scheme for the 2023/24 winter has reached its limit. We have a waiting list for next winter.

When can I expect the camera once I order?


The cameras are sent out on a 'one in, one out' basis. Once a camera is posted back to us by a customer, we prepare it for the next person on the list. Due to the nature of this system, we cannot give ETAs on when you'll get a camera. The best thing to do is keep an eye on your emails for a message from DPD to advise of delivery.

I won't be around to use the camera


Only order a camera when we email you that you can order, if you're expected to be available for the next 2-3 weeks when delivery is likely to happen.

If you've ordered a camera and won't be around then let us know ASAP by emailing or by refusing the delivery when it arrives.

If a camera is already on it's way and you're not home - then it should be diverted back to us.

I need to delay the delivery


You can delay the delivery using the link DPD provides however please be mindful not to delay the delivery for too long. There is a charge for cameras that have not been returned so try not to be delay it for more than 1-2 days.

Why do I need to give proof of return?


We need proof that the camera has been returned so that we can raise any issues with DPD if any occur. If we do not have any proof it has been returned then the responsiblity of the camera will remain with you.

We'd love to know how you get on. Share any discoveries on Twitter or Instagram @octopusenergy.

Stay warm, conserve energy, save money and reduce your environmental impact this winter!
