i was wondering if you can reclaim any charges people may have recieved on their credit cards or if it just applies to current accounts.

You can do, but its not as clear cut as with bank charges.

In April 2006, the OFT made a ruling that £12 was a fair charge for credit card breaches. As a result, you can only claim back the difference between £12 and what you were actually charged.

However, most of the credit card companies then changed their fees to the maximum that they could charge, £12, so you can't claim these charges back.

The time period is 6 years however for claims, so you can claim for charges before the OFT ruling, when the charges were greater than £12.
