Reclaiming mortgage fees

I sold a house this summer after a long legal battle with the lender and I'm now looking at charges that are reclaimable from the period 2008-9 mainly. These are:

1. Monthly arrears fees £25


2. Customer contact fee (monthly) £25


3. Non-DD fee £40


4. Returned DD £30

I'm getting some conflicting details regarding which of these are reclaimable. Can anyone advise please?
