Thanks just ordered 5? Sets.


Don't forget these are only a 10 year investment so you'll need to change them all when that time comes.


Yep there's two versions, the battery only version, which has 6 batteries in it and the batteries last ~5 years and a mains wired version that contains only 3 batteries (so it still works during power cuts).


So you get 2 versions? Wired and non wired?


True, but personally I would pay a bit extra for hassle free returns, but I will add it in the description so that the people have all da facts.

Lol what a load of rubbish that site is, suggesting its basically had a load of fake reviews. Its a good product and its had great reviews...i should know i left one too!


I bought 3 a few weeks ago. ground floor, first floor and one in the loft. Be warned, if you vape a lot, it sets them off!!!


I see your perspective, but some HUKD users sing their praises to this device. I have just experience a house fire which would have been avoided if we had these installed (assuming they work as intended). Personally I think fakespot and similar are best for unknown brands where it is very hard to find genuine objective feedback. Nest however gets lots of in depth reviews, so I feel it is easy to decide for yourself on the value of these 'bad boys'.

Lol I figured ionisation, but couldn't think of the better joke as you did.


could be handy when your engine sets alight on the journey home ;)


(y) Nice one! I believe with ionisation alarms, it's smoke particles and not heat that sets it off, so maybe I should say the deal is "smokin'" instead. I've set that one up for you. Go for it, buddy. (y)


says out of stock with no option to check if its available in local store


Too much heat will set it off 🔥?

Contact your local Fire Service and I expect they will supply and fit free smoke alarms for you instead. Have done in Cornwall for years and the alarms have 10 yr batteries.

Spotted Kidde smoke alarm reduced from £6.50 to 85p in asda. Great price
Get dealGet deal

thought this was a smoke alarm for children :o


Wait the regular price is £6.50 Do people actually buy that? You know you can get fire alarms plus a free install from firefighters? They do this all the time since Fire prevention is what they do most the time


Hope they're not reduced because they're smoke damaged stock? (shock)




Did a quick search before posting myself, found this too in Asda Basildon but they had stickers on rather than shelf label so wasn't sure if store specific or not. Looks like it might be national then :)

Xiaomi Honeywell Zigbee Fire Alarm Sensor £18.36 at Gearbest

No one answered whether this will connect to Amazon Alexa type hubs, has anyone tried this?


And keep in mind that a phone connected Nest smoke alarm is around the £70+ mark. Yes, a fiver for a dumb smoke alarm that will chirp to itself with no-one around, and an unconnected house alarm that people ignore, or a phone connected home automation system that will contact you when you've popped out to the shop, it's your choice.


The only way that this is worth paying the extra for is if you have a ZigBee enabled hub, or intend to install one at sometime. If not then it is going to cost you as much again (at least) to buy the hub and a £40 -£50 smoke alarm with remote smart phone alerts might not be seen as such a good deal.


Mine arrived today but both boxes had their seals broken, do you think they are removing the batteries? I didn't have the same thing on the other Mi Home kit...


CR123A battery £1.99 in screwfix. Edit: Both of mine arrived today (separate orders via Netherlands post - free postage). Each marked 9 Euro and no customs to pay.

Customer services are reporting back as OOS for the wired version with no ETA


Heat from me. I bought one of the BT Shop ones and fitted last night. It's great. Even the wife approved. So need to get another 2, one for the loft which has some wiring I can use, and one for the ground floor, which needs a battery one; and looks like I can get one of each and still do the discount. Thanks, OP!


That’s a great deal for a great product! Luckily I said “usually” (excited)


Well obviously I don't know what future purchasers will get, but I ordered two 3 days ago - they are due to expire in May 2028. So I lost 2 months yes, but not in proportion to the discount! :)


Usually if the price drops it’s because they are old stock, so you don’t get the full 10 years of life. Therefore the price is just a percentage. Two years old stock, pay 80%.

Nest Protect (Battery) for £79 after using discount code @ BTShop
Found 26th JulFound 26th Jul
Great price on Nest Protect, for battery powered only now (wired ones out of stock).

For me, my wife has a habit of leaving the cooker on, leaving the fridge door open, leaving the light on. I love her to bits but she is annoying at times like these, hence for me all this helps!


Bought from your other link. Nice one buddy. (Y)


Pretty sure the rate of house fires is higher than that. This does have other functions as others have elaborated upon.


When the chance of your house catching fire is a million to one why bother spending that much on a smoke detector when a 5 quid one will suffice


I have literally no idea what your point is. Are you saying nobody should have smoke alarms because the noise is annoying? It’s a smoke detector that self-tests and alerts you to alarms while you’re out of your house. It also speaks first rather than irritating you when you burn toast. The motion activated soft light is also awesome when I get up to drain the dragon in the pitch black. I leave my dog at home sometimes so I like the peace of mind to know if the alarm goes off and to call the fire dept and get the hell home ASAP. I’d say they’re worth every penny. I have 3 and love them.

Some still in stock in Penarth!


Didn't realise the fire fighters do this. Everybody needs to be made aware of this. Thanks for the advice all. (y)


As a Firefighter in West Mids I can confirm that the £8.50 ones are the same smoke alarms we fit for free whilst carrying out a safe and well check in your home, if you live in the West Midlands call 0800 3895525 to make an appointment :)


Most brigades around the country provide this service


Although nowhere near Coventry, it might also be worth noting the London Fire Brigade can do home fire safety visits and install free fire alarms for vulnerable people. Not sure if other brigades are participating. Details:

Battery only as far as I’m aware.


Can these be hardwired ?


There's a thread on the ST forum, if you look near the end you'll see some posts about an updated DH which gives you battery life etc. Installed and works fine for me.


Ah has that been sorted now? That’s good.


Also works with the SmartThings hub using a custom device handler. It's been this price for a while now so no need to rush to buy.
