As they have to be interlinked do they also have to be mains powered?

No - you can get 10 year Li battery radio interlinked alarms. Bloody
expensive in comparison, but possibly cheaper than laying in new cabling
(depending on accessibility of the wiring route).

EI-Aico make them IIRC.

Hmm. Is it possible that the new Scottish regs will require the units be
mains powered?
