Yes. The relevant law, RIPA, does not prohibit individuals from recording their own communications provided that the recording is for their own use. Recording or monitoring are only prohibited where some of the contents of the communication - which can be a phone conversation or an e-mail - are made available to a third party, ie someone who was neither the caller or sender nor the intended recipient of the original communication. For further information see the Home Office website where RIPA is posted.
Do I have to let people know that I intend to record their telephone conversations with me?
No, provided you are not intending to make the contents of the communication available to a third party. If you are you will need the consent of the person you are recording.

From http://www.retellrecorders.co.uk/legal/home.htm

You can record without permission, unless you want to divulge the recording to a third party. Only then do you need permission. It is not an issue of copyright - the law that applies here has nothing to do with copyright. It is the Regulation of Investigatory Powers Act 2000 ("RIPA").

Which is what I said earlier.....
