Yep! I arranged mine via Live Chat (as when trying the "Return" option from the orders screen no one got back to me) Already got my refunds now, which is nice. Just a shame they weren't up front about the expiry dates in the first place.


Are returns free?


Both of mine are 2017, what a waste of my time


Received 2 today both Sept 2017 :( both going back.


Unfortunately the second one that came today had the same date - sept 2017. I'd just say to anyone who ordered this, make sure you check.

Seems a great price, down from £107 yesterday.

I have two of these (wired) - they're brilliant - even have a built in automatic night light for when walking along the landing without lights on.


Just got my battery version and similar to you, mine's a week 49 2020 if I'm trading the serial right. (Not opened yet.)


If anyone is concerned, my order of 3 just turned up (wired version) all made in week 51 2020 (December 14th-20th 2020). Very happy with only losing 4 months


Did not know that but makes sense


With regards to them being on a separate circuit, not anymore, they should be on the lighting circuit as when the battery warning sound came on people used to turn the smoke alarm off via the consumer unit, but being on the lighting circuit you're forced to change the batteries or smoke alarm, as everyone needs lighting.

Wish they did. Media headlines some years ago suggested that was the case, but the government only applied the requirement to solid fuel burning appliances (which are in the minority) and not mains gas appliances (which are in the majority).


I ordered two of these and for some reason just one day out of the blue both of the bloody things detected monoxide and went off. Called the number on the back and then the gas board who promptly sent out some joker who basically cut off our gas supply and went home. Turned out both units were faulty and there was nothing wrong. In fairness they sent out 2 units FOC but just letting people know before the internet police start hammering me. Also be careful the 7 year life is 7 years from manufacture not from when you buy it, so if it's been sitting on a shelf for a year..... A good price though, heat added.


To be cautious you could fit one in her loft and one in her bedroom. After all, it detects dangerous of carbon monocide, so her room would seem a better place for it. When my boiler was serviced, the engineer moved my detector from the boiler cupboard to the bedroom. He told me this would also protect against leaks from flats above and below who haven't had their boiler serviced.


That's because "Social Housing Providers" which I assume councils are, are exempt from the carbon monoxide legislation, I'm not sure why.


I agree

Let's go with: it's a 7 year lifespan then.


Have one in my camper van. Good deal


The Kidde site says "End of Life Warning – Seven years after initial power up, a Kidde CO alarm will begin chirping every 30 seconds. The chirp will not stop until the unit is powered off. WARNING: The alarm will not respond to carbon monoxide in this condition." Only lasts seven years.


Bit misleading... The sensor is expected to last 7 to 10 years, the batteries aren't. They sell a sealed for life version with a 7 year warranty.


Good deal. A battery that will last the length of lockdown. :D
