Nest Protect Expiration Date
As you can see mine shows replace by April 2026 although I didn’t buy them until end of Aug 2018 and fitted them a couple of months later. I’d better start saving up for the next ones now!



So i didn’t get the full product at a discounted price, simply received a reduced lifetime at a higher prorata cost :(

Can’t tell you about the end of life nagging but i suggest all potential customers wait till my 2026 expiry, when i will be able to give clarity. before buying unless Nest want to answer your question sooner?
