Oh good tip thanks. So it seems like the £35 per tree is a scam for the uninitiated.
On another note, I am just looking up roundwood to buy and I can't find any. Ironically it may be cheaper to buy unprocessed wood but that is no use if I can't find any to buy as a layman! Seems much easier to buy processed, expensive timber from the local merchant yard.
Are there any other tips for getting hold of cheap wood to make small structures like a shed and a cabin? Don't care if round or not. Not fussy what type but straight so I can make walls and roofs.
