OK. Depends what the music is and what the character of the band is. Some bands dont like hi tech 'posh' studios with lots of people about, some want only the best, some want to be in country away from it all, some can only be in the city. Depends on budget also..
but here goes: There's not many left..
Abbey Road Studio 2
RAK Studio 1 (for tracking) ,2,3 (mixing)
Sawmills Studio Kernow for tracking and vibe
Rockfield Studio 1 or2 Monmouth (legendary)
Doghouse Studio Henley on Thames (cozy but great sound)
I've heard British Grove is good but never visited
