House / smoke / carbon monoxide alarm

[sidicks]

Our smoke alarms are now 12 years old (according to the back of the devices, they should be replaced after 10 years (2014)).

Now I am a bit sceptical about this sort of 'expiry' date, but they have been beeping a bit more randomly recently (possibly due to needing new batteries), but as we also need to get a fault with our burglar alarm investigated, I wondered this was the time to review the whole 'system'.

Presumably since the house was build 12 years ago, technology has moved on and no doubt there are much more sophisticated systems now available?

Does anyone have any experience in this area - which brands to go for?
Any installers in the South East?

Thanks

I keep it simple
Have them in the key places like the landings and halls on the ceilings


Then Just have bonus ones like behind the tv in the lounges etc

Carbon monoxide next to the boiler and gas fire

Change batteries on my birthday


So cheap if you shop around it's crazy

The house was a new build 12 years ago, so already has sensors all around the house. I wondered whether the 'head unit' can be upgraded, retaining the existing wiring etc, to minimise costs / disruption.

I have just replaced the wired smoke alarms in my 16 year old house with Nest Protect detectors. Not cheap but were very easy to fit and saves need for separate monoxide detectors.

Sounds ideal, I'll take a look.

Thanks
