The newly-increased Repair Directory
Work on this began some years ago, focusing on north and east London, but has now expanded to cover the west side of the capital, thanks to the sensible collective waste authority over that way. So it should be useful to ever more people as a result, as well as giving more folk an incentive to recommend more of their local small businesses for inclusion in the directory.
