I apologise again for slowness. (Partly due to my router getting fried by a lightning strike!)

I don't think that follows. If the partnership (or LLP) operated a tea shop in Canterbury and the individual operated one in Cambridge, I do not think they would be regarded as the same trade, even though the individual is deemed to carry on both.

Agreed, there is the caveat of 'unless indicated otherwise'. The legislation does indicate otherwise in some places, eg, regarding obligation by a company to deduct tax when paid to a partnership. But I don't see that it indicates otherwise here!

It does, but s847 sets the scene by explaining that 'firm' is really just shorthand ("In this Act persons carrying on a trade in partnership are referred to collectively as a “firm”.").
I agree that the partnership/LLP provisions get to round about the same result in different ways. The general partnership rules carry on the fiction of the firm having a separate identity for the purposes of computing profits and allocating them, but nevertheless recognise that in law it is actually the partners themselves carrying on the trade. LLPs have a separate legal identity of course, and my 'take' is that s863 treat the partners as if they were carrying on those activities themselves, exactly as non-LLP partners do.
