We tried this out last year, sending hundreds of these cameras to homes with unexpectedly high energy bills (based on factors like consumption data and home efficiency stats), and the campaign was a resounding success!

After offering truly useful, tailored advice based on their own homes, we found that people were eager to use that information to stay warm for less. Perhaps unsurprisingly, this proved much more effective than more generic messages about energy efficiency you see every winter.

In many ways, these nifty little thermal cameras encapsulate everything we're about. As your tech-led energy company of the future, we are committed to using cutting-edge technologies to lower both your carbon emissions, and your bills. As our CEO, Greg Jackson points out, these cameras also reflect the way we stand up for our customers too. When you compare us to other outdated ‘legacy’ suppliers, the difference is stark: 'While other energy providers might pray for a cold winter, we are committed to keeping customer costs down.”

If you do want to know about other ways you can improve your home's energy efficiency, take a look our best energy saving tips.

Here are some budget-friendly tips (some totally free!) on how you can reduce heat loss in 9 different areas of your home:

Doors

• To block draughts at the base of your door, you can buy a cushion draught excluder (~£7) or make one by stuffing tights with socks, rice, plastic bags or any spare material you have. If you're feeling a bit more creative, you can sew material into shape and fill with whatever you have available (here's a tutorial on making your own draught excluder with stuff from around the house). The photos below show a draughty door - we know this because of the dark blue areas around the door. The photo on the right is lighter in colour at the base of the door where a draught excluder (a rolled up old towel) has been placed. The lighter colours show that the area is now warmer and the draught is being blocked. Easy remedy!

• If you'd prefer a fixed draught excluder, you can install a brush strip or hinged-flap draught excluder (~£7). Here's a tutorial on how to install a brush strip draught excluder.
• For draughts around the edges of doors, use self-adhesive draught-proofing strips. Foam strips are the cheapest option (~£5) but may not be long-lasting. Other options include plastic or metal draught-proofing strips. Here's a step by step guide on how to install self-adhesive draught-proofing strips.
• Letter boxes and keyholes can also be draught-proofed using a metal keyhole cover (~£3) and a letterbox brush/flap (~£5).
• Closing curtains in front of external doors helps to block the cold out and trap the heat in. The photo below on the left has lots of dark blue areas. This shows that cold draughts are coming in through gaps around the door frame and the window is poorly insulated (single glazed). The photo on the right, with the curtains closed, is much lighter in colour. This shows that the area is now warmer as the curtain is blocking the draughts out and trapping the heat in.

Windows

• Whilst the sun is shining, keep curtains/blinds open to let in the free heat from the sun. When the sun sets, close curtains/blinds to keep the heat in and the cold out. Curtain liners (or even a shower curtain) can be added during the colder months to thicken existing curtains.
• Draught-proofing strips can also be used around windows that open. Here's a step by step guide on how to install draught-proofing strips around your windows.
• Silicone sealant (~£5) can be used to seal any draughty gaps around the edges of windows.
• Secondary-glazing window insulation film (~£8.50) can be used to create a temporary double glazed window effect to reduce heat loss during winter periods. Here's a tutorial on how to use secondary-glazing window insulation film.

Unused rooms

• As heat naturally flows from warmer to cooler spaces until there’s no temperature difference, keeping the doors of unused and unheated rooms closed, saves wasting your valuable heating.
• A cushion draught excluder can also be used at the base of the door.

Loft hatches

• A loft hatch insulation pillow can be purchased (~£24) or made by stuffing a black bin bag with fibreglass, old cushion stuffing or any spare material. It can then be secured to the loft side of the hatch using duct tape.
• Draught-proofing strips can also be used around edges of loft hatches to seal any gaps. Here's a guide on how to install draught-proofing strips around your loft hatch.

Extractor fans

• Leaving an extractor fan on can chill your whole house, so remember to turn it off when you've finished using it.
• You can get a timed extractor fan to help ensure it's not left on unnecessarily.

Chimneys

• If your chimney is still used, you can buy or make your own removable fireplace guard to help reduce the draught. You just need some spare plywood or thick cardboard cut to size and insulation tape/kitchen foil. Whilst the fire is off, fit it into place in your fireplace. Here's an example of how to make a removable fireplace guard.
• A removable chimney balloon (£16) or a chimney draught excluder (~£22) can be placed up the chimney to prevent heat loss whilst the fire is off. If you use one of these, don't forget to remove it before lighting the fire!
• If your chimney is no longer used, consider having it capped by a professional (~£150).

Floorboards and skirting boards

• Place a rug (or leftover cuts of carpet) over exposed floorboards to reduce draughts through the gaps.
• Filler can be used to seal gaps in your floor/around your skirting boards - it is best to use filler that can tolerate movement as the boards can contract and expand.

Radiators

• Radiators need space to heat your rooms - move any objects obstructing your radiators such as sofas, and ensure curtains don't hang in front of them.
• Dust that builds up between the fins of radiators makes them less efficient - try to remove dust build-up using a vacuum and radiator duster (~£5). If you have radiator covers, here's a step by step guide on how to remove them so you can access the radiator fins.
• Trapped air in radiators also reduces their efficiency - if there are cold spots on your radiators, it's a sign they need bleeding to release trapped air. Here's a tutorial on how to bleed your radiators.
• A shelf positioned just above a radiator helps to push heat forward into the room, rather than letting it rise to the ceiling. You can find easy to install, clip-on shelves in most hardware/DIY shops.
• Insert radiator reflector panels behind radiators (most effective on radiators located on external walls) to reflect heat back into the room, instead of letting the heat escape out through an external wall.

Hot water tanks and pipes

• A hot water cylinder jacket (~£15) can be fitted onto your hot water tank to reduce heat loss and therefore keep your hot water hotter for longer.
• Exposed hot water pipes can also be insulated using a foam tube that covers the pipes between your hot water cylinder and boiler.

If cold draughts are ignored, your heating has to work harder to keep you warm, increasing your energy bills and your carbon footprint... and no one wants that. So plug those draughts and stay warm this winter!

We'd love to see any nifty tips you come up with to stop those pesky draughts! Please share your photos with us on Twitter or Instagram @octopus_energy.

Good to know, the government currently has a ‘Green Homes Grant’ available to help reduce household energy use. The grant can help fund installing double/triple glazed windows, cavity wall insulation, roof insulation and more.

Check out our customer Grahame's before and after cavity wall insulation photos using our FLIR camera. The photo below on the left shows Grahame's house without cavity wall insulation. The bright colours indicate that a lot of his heating is leaking out through the poorly insulated walls. The photo below on the right shows Grahame's house with cavity wall insulation. The walls are much darker in colour, showing that the external walls are now colder and significantly less heat is escaping out into the atmosphere. Cavity wall insulation can save you up to £160 a year on heating bills!

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