This exact question came up recently on the UK_Selfbuild list. FWIW, I
think it's a really *bad* idea, and you still may need planning/listed
building consent if you do still go ahead. You should check with the
planning office to be sure.
Anyway, here's the UK_Selfbuild Q&A.

HTH,

Answer:
'Well ventilated' is not the same as having free air flow.
The outdoor unit will be putting out at least 2kW (for a 1.5kW indoor).
That'll heat up the attic considerably.  The hotter the attic gets, the
less cooling the indoor unit can do.  Then there's a maximum temperature
the outdoor unit can work at.  Also, the hotter the outdoor unit
environment, the shorter its life.
