As part of buying a new house I'm looking to replace the 3 existing interlinked mains powered smoke alarms with 3x Nest Protects, the problem I'm having is the heat alarm.

I believe building regs states the heat alarm needs to be interlinked with the smoke alarms, but from what I can see Nest Protect doesn't interlink with any 3rd party alarms?

So is the only workaround to leave the old heat alarm and install 3 nests and leave the nests interlinked but no link to the heat alarm?

That's exactly what I did a couple of years ago. The original heat sensor is still in the kitchen. I wasn't even aware it was a building reg to have them interlinked. I've still got the originals an can stick them back up if I move.

What happens if one of the original smoke alarms packs in and you can no longer buy a replacement? Are you then supposed to replace all smoke alarms and heat alarm because one is broken?
 
Ultimately they look better and the 'smart' features (i.e. notification on phone and announcing what's detected where) is my push for getting them installed.

I believe building regs state they must all be interlinked, but I suppose it wouldn't matter until I went to sell the house, so I could just have the 3 smoke alarms set up and the heat detector on its own, then stick up the originals if they're still in date when I sell.

I'm surprised Nest haven't thought of something for that though, given all new builds need to comply with that and I'm sure it won't be limited to UK/Scotland building regs..
 
Don't forget Nest is a US company, the building regs (code) are very different and vary state by state.

I have thought about getting the nests in the past but when I really thought about they just didn't pass any kind of 'value' test for me. Fire alarms are all about saving lives by alerting you to a potential danger (normally when you are asleep). If you are at home you are not going to be checking your phone if the alarm is blasting ;).

If the alarm goes off when you are away, what are you realistically going to do? Are you going to call 999 to tell them your phone says a fire alarm might be going off? It's unlikely they are going to come out until someone actually confirms it isn't just burnt toast.
 
Being location aware is useful (i.e. there's smoke in the living room), I also work 2 minutes around the corner so if I did get an alert I'd start running :P
