I looked here for a recommendation & found a post (from about a year ago) for this company:-
Little Oak Tree Care, 23 Wood St, Hackbridge, CR4 4JT
Tel 02082870543 & +447931735779 & 07749416359.They've literally just left & we are delighted & pleased with their work. They were professional, prompt, efficient, worked quickly, took the waste away & tidied up, not only our garden but the neighbour's garden (because it overhung theirs a bit). We thought the price was reasonable for the work too.A much better job than the previous company we used. I wouldn't hesitate to recommend them.
