Homebrew PCBs

Can anyone suggest a UK supplier of small quantities
(i.e. offcuts) of flexible or thin scissor-cut pcb stock?

Possibly a board manufacturer in the North London/Mid Herts
area who is willing to sell scrap on the doorstep for cash,
to minimise paperwork and carriage.

I know I can order small sheets of flexible from Mega in
Cambridge for a fairly high price but I could utitilise pieces
2 inches square or less and I'm hoping I can get it cheap.
