Hi Matthew
Welcome to the Forum!
As AlanB says, it isn’t surprising to find a hedgehog in a town. Many people may be surprised to know that hedgehogs are actually doing better in towns than in the countryside at the moment as recent research has shown.

Consequently for the that reason and the reasons given above by Alan, it wouldn’t be a good idea to move the hog to the country.
Did you mean that the gardens are walled as well? Would it be possible to make hedgehog sized holes in the boundaries (about CD size)? What sort of behaviour is the hedgehog showing which makes you think it’s trapped? If it got in, it must be able to get out. But if you are sure it can’t get out, then follow Alan’s advice above. Also, if the hog was out during the heat of the day, that is not normal and may indicate that it’s unwell, starving and/or dehydrated and needs help – in which case contact the BHPS to find your local carer.
One of the main aims of Hedgehog Street is to increase the habitat of hedgehogs by linking gardens together. If it is at all possible to do that and encourage your neighbours to do likewise that would be the ideal thing for that hog and any others in the area.
Meanwhile, leave water out for the hedgehogs 24 hours a day and encourage all your friends and neighbours to do likewise. If there is one hedgehog around there are likely to be others.
Good luck. Let us know how you get on.
