Where do i get a male mouse neutered?

I have 3 mice who were incorrectly ed at the pet shop, resulting in two of them now being pregnant. Subsequently, i have separated the male from the 2 females. however, they got along fine and i don't want him to be on his own in a small cage. i want to get him neutered but i dont know what vets do it and which to trust. any help would be much appreciated. I live in the north manchester are, btw
