The word 'or', in your question, may be incorrect. I suspect it should be 'and'.
With only certain exceptions, anyone has the right to see any information held about them on computers (and sometimes on manual systems) by any organisation. (For example, anyone can demand a copy of any video recording, showing themself, taken on a CCTV system. Or they can demand a copy of their 'police record').
However, in order to prevent organisations being swamped with loads of possibly unnecessary requests (and to help pay for the staff time invloved in finding the information), a charge may be made for providing the information. The maximum charge is regulated by law, and it's currently �10. (In practice, it's not only the 'maximum' charge, it's also the 'standard' one).
Also, those holding personal data are allowed a maximum period of 40 days to supply the information.
