Buy Land Plant Trees

At the core of Chimney Sheep is our Community Interest Company, Buy Land Plant Trees (BLPT). For every purchase you make with us, 20% of the profit facilitates the planting of trees on agriculturally poor land in Cumbria.

We set up BLPT in 2019 as a ‘boots on the ground’ tree planting initiative. The company is run by us and the tree planting is done by us. We do it to help you and us to reduce our impact on the planet. The trees we plant reduce CO2 output as well as contribute to the reduction of flooding and the creation of habitats for wildlife.

BLPT isn’t a tick box exercise nor a distant and detached carbon offset company. In fact, this is as much part of our business as the products we sell and is an integral part of our ethos. We are big believers in the phrase ‘think globally, act locally’ and want to make a genuine difference

A very useful bit of Insulation

Great speedy service, my house is now significantly warmer and quieter thanks to this wool, saved me a fortune!

Henry P

I got some loose wool to fill gaps around some refitted windows before the carpenter finished. It worked exactly as I hoped. It can be pushed into almost any gap and I can feel the difference already. I didn't know which size to buy... does anyone know how much wool weighs?! I bought a half kilo box and a kilo one. These are very generously packed! There is a lot of wool here. We are only half way through the small one, but are already planning what to do with the rest. It would help if the website gave a sense of the quantity.


Excellent draught excluder. Great value for money.

Wonderful product

Ordered a kilo box, absolutely loads, filled cavities great and has really helped with the draughts, loads left over for future projects, really glad I've used an eco product too, thanks

Amanda Shaw
No more drafts!

I'd been living with a draft from an unused chimney for years. A quick Google and this sounded perfect...and it is! Easy to use and now no howling East wind and I can definitely tell the difference in temperature. Natural, quick and easy solution, wish I'd found it years ago!! Thank you
