Line hunting across analog lines is possible and it is free. BT call it 
Auxiliary working. Take a look at this page:

It's not something they often do on home lines so be prepared for sales 
staff who don't know what they are talking about.

DDI on analog lines is more complicated and I believe there is a set-up 
charge of over £1000 (see 
http://www.serviceview.bt.com/list/current/docs/Exch_Lines.boo/1228.htm 
) If you must have multiple numbers you'd be better off with an isdn line.
