This is on the back of a Court of Appeal ruling a couple of weeks ago.

He then added: "While not specified in its announcement, I've had it confirmed this applies to ALL car finance commission complaints, not just the Discretionary Commission Arrangements (DCAs) complaints previously covered." This could mean that in future, the FCA could look more widely in its car finance investigation, not simply at the 40 per cent of past claims that had DCAs (where dealers could increase their commission by increasing interest) but all commissions including fixed commissions.

Mr Lewis added: "It looks like (I need to dig) if the hold is extended, almost everyone who has had car finance deals may have a complaint.
