Problem is that when you pay £150, they completely neglect health and safety (it's just a lad, and his mum won't miss him), insurance (that's going to be expensive, let's leg it), and everything they remove will end up flytipped down a local lane, because all those things mean you can't get the work done for £150. Plus there's a lot more to proper tree surgery than owning a chainsaw. That said we pay a man who trades under the name of Angry Beaver.
