If it has been there 25 years and there is no obvious sigh of a problem
I would not be too worried.

Would be council grant this retrospectively, or is this just planning

You could apply for a regularisation IIRC.

I will give the Building Controls office of my council a call tomorrow
to see what they say.

Probably a good idea.
