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

Easy to install and good value

The letterbox draught excluder was very easy to install and has performed well. Great value for money.


Had to do a bit of fiddling to get it to fit our 200 year old door and victorian letterbox, but it seems to be good. Postman is having problems putting mail through, but they get there in the end. Definitely reduced draughts.

Jo holley

I am pleased with this as it stops the draft, the brushes do fall out if bulky post comes through but I’ve got the knack of putting them back in so its ok

Miss K

Was easy to install and looks great. Cheaper than Homebase.
