About Chimney Sheep – The chimney draught exluder
“There’s a bat in my house, and the only way it can have got in is down the chimney!” When I operated the bat helpline for Natural England, I received calls like this on a daily basis. It made me aware of just how many open chimneys there were. I researched further and found that chimneys are designed to draw air out of a property all the time. They don’t just work when the fire is lit and stop working when the fire goes out. They constantly pull air up and out of the building, removing all the centrally heated warm air in a room within an hour and causing cold air to be pulled in from around doors and windows, creating the draughts we notice.
I realised there was a need for something that was versatile enough to block a wide range of chimneys sizes, that was easy both to put in and take out, that blocked the airflow but still permitted the chimney to breathe, and that wasn’t too expensive. The answer was all around me where I lived in Cumbria: wool! Wool is a natural insulator, is breathable, sustainable, compressive, malleable. It took a while to transition from idea to prototype to design to commercial product and there were a few trials and tribulations along the way. If you’re interested I go on about them a bit in some of the blogs. But I’m very grateful for all the help I received along the way.

Chimney Sheep® stops cold chimney draughts
How much heat are you losing up your chimney? Chimneys are cleverly designed to draw air up and out of a building. If you’ve got the central heating on and the fire isn’t lit, all your precious warm air will disappear up the flue within an hour. Just put your hand in the flue and you’ll be astonished by how strong the chimney draught is. This escaping air needs to be replaced, so cold air is pulled in from under doors and round windows, creating the cold draughts we feel. Now you can stop chimney draughts and reduce chimney heat loss with a Chimney Sheep®! The Chimney Sheep® is a thick layer of felted wool on a handle that plugs the gap just above the fireplace preventing warm air from escaping up the chimney and stopping cold air from coming down the chimney.
Fitting a chimney sheep will save around 4% off your heating bill. That means it should pay for itself within 6 months.
Having an open chimney is like leaving a window open all the time. Fitting a Chimney Sheep® effectively closes the window.
A lot of happy customers tell us their homes are quieter since they fitted a chimney sheep.

Just wanted to say my chimney sheep arrived within 2 working days of ordering – well done. It’s great to be able to support our sheep farmers who I know from watching ‘Countryfile’ struggle to make money from fleeces. I was also very pleased to have an environmentally friendly way of stopping the draught from our chimney. We don’t have a fire and the ‘sheep’ is more a permanent item. I was also pleased to support fair trade by buying the lovely butterfly to hang from the ‘sheep’. Will definitely recommend you as I was told about your firm by my brother. One happy customer
