Thin bricks, brick veneers, brick fascias, cladding ...

[gt43]

Anybody know where I can get red brick veneers (similar to those "thin bricks" they used to sell for cladding fireplaces, but for outdoors) in the London area ?

I only need a few to tidy up underneath a new front door, so don't want to have to go to Worcestershire (or wherever) to get them, but they don't seem to be that easily available. Wickes don't do them any more ...
