A little while ago there was an article going round outlining photographers rights but it was written with USA law in mind. Not so much use for brits. Luckily here is a PDF with reference to UK law.
UK Photographers Rights – Sirimo.co.uk
I need to read it when my head is clearer. It seems you can take pictures of most things and places with certain specific restraints, even on private property if you are allowed to be there and there are no signs that specifically say photography is not allowed, but then people raise data protection and terrorism laws…
It is a well written document though, well worth a look!
