Personally I would not worry. Fish lice do not look much like woodlice. What you're probably seeing are Water Lice, which are related to woodlice.
With regards to leeches it depends on the species. Lots of them, especially the smaller ones aren't parasitic. There are only a couple of species in the UK that will attack fish, and the best way of getting rid of them is to drain the pond and leave it dry for over a month. THe fish leeches that you're likely to see in the UK are fairly distinctive striped animals with large suckers. Most of the common leeches aren't anything to worry about.
