In the 17 years living in Orpington we've had more tree surgeons than I can remember - and in each case their card went in the bin. Poor quality work, leaving huge amounts of rubbish behind, damage to borders, smoking when requested not to and so it goes. Down to Earth Trees Ltd were recommended by two neighbours both of whom don't suffer fools. Their quote felt sensible, the people were personable, checked the appointment the day before and turned up on time. Work quality was excellent, a bit of extra work was accommodated without comment (or a change to the bill) and this is one firm that I a) asked for their card to give to others; and b) are now are go-to firm for this work. We've tried the rest and as far as my experience goes - these guys are the best. Unhesitatingly recommended.
