Several pictures of mottled tadpoles, swimming under water and coming to the surface occasionally. I saw newts in the pond, but I have checked reference sites and think the mottled tadpoles are frogs. On the other hand, I think the crowds of smaller, black tadpoles that can also be seen in some of the pictures are probably toads, because they are black and because they are shoaling.
In one picture, a tadpole has its mouth at the surface - I don't know whether this means it is feeding or breathing (not sure when they start needing to surface to breathe?)

I think your research has

I think your research has paid off and you are completely right. I can see both common frog and common toad tadpoles here. The toads breed later than the frogs so their tadpoles are smaller.

The tadpole at the surface is probably feeding, perhaps on algae. They will have developed all four legs before they need to breathe air.
