Battery smoke alarms are not covered by the Building Regulations, the stipulation is still in new builds they must be mains powered, it is accepted practice to fit battery smoke alarms in existing dwellings although the recommendation is that during a major refurb the choice of mains powered should be considered.

Building control can only coerce, encourage or educate the client in the merits of fitting mains powered smoke alarms during a major refurb but it is still up to them whether they want them fitted or not, in all fairness a couple of battery alarms is better than none and some of them now especially the 10 year lithium type are quite good.

As Rocknroll says only hard wired & with battery backup are acceptable under Building Regs.

Recent publicity/ editorial for a certain make may have led many to assume they were a straight substitute for hard wired.

You can however use the radio link detectors that comply with BS5839 pt6. These still have a mains supply to each detector, but the link between is omitted. This is handy if its a problem installing a link cable as is often the case. Very good and simple in my experience.

ABSOLUTELY.

Stick to those that are mains powered RF bases with rechargebale back up, rather than the cheaper one from BRK that just is battery powered only ie no secondary supply.

This is mains with back up:
