Rats are everywhere. Make sure you don't leave any food around. If you decide to put poison down you can put 'throw packs' inside lengths of drainpipe, which you put alongside walls, etc, where rats are likely to run.
The Environmental Health or its equivalent will tell you if you have rats, but it is up to the householder to do something about it if they wish to.
They can also be trapped, but you have to be certain how you are then going to kill them. Know anybody with a suitable gun?
