Which UK companies do customers complain about most?

Regulators publish complaint figures every quarter, and most people never see them. We pull the raw numbers from Ofcom, Ofgem and the CAA, rank them sector by sector, and let you see who’s actually worth your money — and who’s counting on you giving up. Every figure here is verbatim from the regulator’s published dataset.
