Dunno where you are, but we buy wood from Forestry Commission – speak to you local office. Bought a load early Dec – about 7-8m3 for £105. This is fresh though so will be next winter before we can burn it. Comes in big 3m lengths so you need to be able to collect, transport, cut, split, store and dry it. Not a quick fix!
Can also get a scavenging licence for £50 to go in and collect your own after they’ve been felling. But that’s a pain in the hoop for sure – not allowed to use chainsaw on FC land unless you are qualified to do so and carry £1m public liability cover.
