As per my other recent post, I picked up some information on nextdoor.co.uk which appears to indicate that “all” homes in Scotland must have inter-connected alarms installed and working by February next year (Feb.2021)
Link to gov.scot with info on legislation etc.
Sykes the electrician in the village have posted some info from “Select” and it can viewed via the “nextdoor.co.uk” website.
This is the same leaflet direct from “Select”. Alarms.pdf
I most certainly have not received any information about this, but it does appear to be genuine.
