Yes, those are newts. Similar shape to lizards, but actually amphibians. When they are in the water they grow fins along the back, but at other times they do look very like lizards.
There are three different native newt
species: palmate, common or smooth, and great crested.
Then there are three true lizards: common, sand and the slow-worm, which is a lizard but has no legs and looks snake-like, but with lizardy eyelids and small mouth.
Yours are probably smooth or palmate newts. If rather warty-looking and very black, could be great crested.
