In response to my original post:
I phoned up the Basford (Nottingham) site of
http://www.alignment-services.co.uk/ who told me they do a full computerised alignment check of all 4 wheels for £35, including front toe adjustment. Additional adjustments to camber or castor (where adjustable) were £8 per side if needed.
Anyway, I went there on Saturday.
The chap seemed very friendly and helpful; they have a Hunter computer alignment kit which he took good care in mounting on the car before taking any measurements.
Everything seemed in order except the front toe which was out (well, in actually! but I expected this).
Got a before/after printout of all the geo settings too.
So if you're round the East Mids area then well worth checking out, especially for £35.
Fairly easy to get to from M1 J26.
(Sorry JBS, I feel like a traitor after all your replies earlier; but this place check everything I wanted, give a full before/after printout, and were cheaper
)
