Why can you not use the "RCD Consumer Unit" as an isolator?

Because the CU also supplies lights & patio power sockets

OK, fair enough...

Is it actually isolation you need or functional switching?

Isolation for the hot tub only

A 3kW hot tub will actually only draw 13A not 25A. Hence a simple double
pole switch such as:

would be fine.

If you really feel you need the ability to switch 25A for some reason then:

Would do the trick.
