British Library – You MUST send them ONE copy
The British Library is entitled to delivery, free of charge, of one copy of every publication within one month beginning with the day of its publication. The copy deposited must be “of the same quality as the best copies which, at the time of delivery, have been produced for publication in the United Kingdom” [Legal deposit Libraries Act 2003]. The British Library will issue a receipt for every work deposited.
The copy for the British Library should be delivered to:

IN ADDITION – 5 MORE COPIES IF REQUESTED
The legal deposit libraries act (2003) requires that five copies of each publication distributed in the UK or Ireland be sent to the Agency for Legal Deposit Libraries (ALDL) if requested. This is in order to preserve the literary heritage of the country for further generations.
So, if you are printing your book, you should reserve 5 copies to send to the Legal Deposit Agency if requested. The address for sending these copies (if requested) is –
Agency for the Legal Deposit Libraries
NOTE – you can send these 5 copies if you wish anyway, without necessarily waiting for a demand.
