It's the responsibility of the land owner who you have said is Caligen/Vitafoam. If there is a protection order on them, which might be their excuse, they will have to apply for planning permission. I had to do it when I needed to cut mine down in a conservation area. The planning form is easy enough to fill in online and for trees there was no cost for me. Might be a charge for a business I don't know.
If you go to this link on HBC's website it shows all the tree preservation orders (TPO's) in Hyndburn so you can check if they are right. Is the area in a conservation area? If it is trees are about the only thing that applies in Hyndburn as they have never set the conservation areas up fully - they never applied an article 4 direction to remove permitted development rights making conservation areas almost useless.
