an interesting contrast because I'm sure that for tax purposes they cannot claim to be resident LL, and so cannot use the rent a room scheme

They could, as long as total rent (before any allowable expenses) was less than £7,500 p.a. Ain't gonna happen in this case but might in a one-bed annex somewhere heavily downmarket....

Expecting the UK taxation system (or benefits system or sovereign grant...) to be fair & reasonable is likely to lead to disappointment

Sounds like you may have a mixed use site if you move into the annex and turn the main dwelling into a HMO. Contact the planning department, as this almost certainly needs PP as you are turning the annex to a C3 residential dwelling.

Edit, the mainhouse would be smallscale hmo if less than 7 unrelated people lived there, and would not usually need pp. However as you are in a wholly self contained annex this cannot be defined as part of the smallscale hmo use class.
