Perhaps they have been lobbying. Electrical work in a kitchen - lots of money!
Judging by the cold calls that used to be left on my answerphone suggesting that any gas boiler installed before a certain date was illegal and to avoid possible prosecution I should immediately call for a quote I guess this will start an avalanche of similar calls in Scotland threatening possible legal action for not having "professionally" installed smoke alarms.
If smoke alarms become a legal requirement are the house/contents insurance companies going to insist on proof the systems are properly installed AMD maintained? This may rule out DIY and ad-hoc installation by your fire brigade.
