Oddfellow:
You are only entitled to a refund of the DIFFERENCE between what you your original contract stated and what you actually paid and then only if the lender can justify (to the FSA, not to you) that the additional cost is valid.
Not entirely true as "under UK contract law, you can't fine someone for breaking a contract, you can only charge them an amount proportionate to the cost of the breach. The actual administration cost to a mortgage lender of closing down a mortgage isn't thought to be much more than £50 so it's arguable that you needn't pay more than £50, regardless of what your contract says. Therefore writing to your lender, asking it to justify the charges with a full breakdown, and if it refuses asking for a full refund, can work." [MSE quote]
Even if you only get back the difference as tengis19 £100+ for the cost of a call is still good
