Thank you Nic for your reply and so sorry for such a late one from me.
In the end I rang up one of the local vets (there are 2) and the larger one is obviously very set up to help hedgehogs and I spoke to a nurse there before I went who indicated that they had people to take the hogs to if appropriate, and took my details too so that the hog might be returned to me if it recovered to be released in the same area it came from.
Because of my mother’s death, I have had a lot to do since,and a week has gone by since it went to the vet. I rang up today and spoke to the same nurse, and it seems that sadly the hog didn’t make it and died when with them. Apparently it had hundreds of ticks on it, and had bad anaemia. He did say that normally they have a good track record with hedgehogs so it must have been in a bad way though wasn’t drastically underweight (was 400gm) as I had weighed it.
Very sad but at least I now know a good place to take any more sick hogs. No mention of charging me too!
Incidentally I did make sure that the hog had plenty of space to move off the hot water bottle which was well covered with towels, as it was quite a large box.
