I don't know about the UK, but in Australia it's attended by the candidates' representatives, called "scrutineers". The counting is done at the polling place, so the candidates can't be multiple places at once.
I've scrutineered before, and it all seemed to work well.
If you tampered with the ballot it would only be discarded due to the rubber marking in the "wrong" box
