I can't think of any

Noah's palsdid a good try, but Schleich bought them and shut them down

If you mean modern brands working at the same scale as Britains the answer is no for the most famous ones. Though, you can find a few working companies releasing some farm and horse figures at 1:32 scale.
If you mean brands which work at an exact scale but not necessarily the same as Britains, the answer is also no for most of them but you can find a few series where a certain scale is taken in consideration.
If you mean if among major companies there are figures compatible with Britains, the answer is yes for a small minority, I'd say elephants are basically the only figures of the major companies which can be used at 1:32 scale.
We have a superb topic showing figures of all kinds at 1:32 scale, you can find it [You must be registered and logged in to see this link.]
