New Fire Regs for Holiday Lets

Hi - Anyone here familiar with the new laws that came into effect on 1st October, regarding fire safety?

I’m told I need a wired in and linked smoke alarm in every bedroom. However, just called my electrician to arrange for him to do it and he says it’s not a law just a guidance, therefore I don’t need to do it.

He also said a battery powered (not wired) smoke alarm by Aico is an acceptable alternative to having them wired in. They are expensive compared to normal smoke alarms but is obviously a LOT less difficult to fit as doesn’t involve chasing in wires etc and can be simply screwed into the ceiling.

Any thoughts?
