From their website: "Charged to cover the administration of issuing an arrears chase letter." - Outgoing arrears letter I'm not condoning missing mortgage payments, but surely £27.50 is a lot for a one-page (presumably computerised) letter and envelope being sent out? I think this has been covered previously (in 2011) but I'm not sure of my best course of action. Or whether I have a claim at all? Can anyone help me? I have received 2 of these letters in the last fortnight alone. £55 is hard to take for 2 sheets of paper and 2 envelopes! This figure is clearly exceeding actual administrative costs, and I find them unfair and therefore unlawful. Are they well within their rights to charge such a figure? Sometimes I have had these letters without even a prior phone-call to chase/remind me to make payment.
