How many alarms are you wiring?
Follow the manufacturers instructions for the siting and wiring of the alarm(s).
For one alarm you would take a live, neutral and earth from a ceiling rose for example using 1mm ² T&E and run it to the alarm.
If you have a second alarm then you need to run 1.5mm ² Three core and earth from the first alarm to the second.
Although the earth wire is not required you should ensure its continuity through the last alarm - most alarms now have a 'parking' place for earth wires.

I can understand the heat and carbon monoxide alarm requirement but if this is a residential property then that is a lot of alarms - must be a big house

By the way I have edited the 3 core and earth wire to 1.5mm ² which seems to be the manufacturers recommended size.

It is down to personal choice - ie one battery operated smoke alarm properly maintained one is better than none.
For rewires I normally fit one in the downstairs hallway and interlink to one on the upstairs landing unless I am asked to fit more.
I believe bedroom fitting are down to whether the door is left open or closed (how you can cater for that I don't know) - so one in each room seems fine to me.
Be advised though that some manufacturers of these alarms limit the number of interlinked alarms or the total distance of the cable. I think with Kiddie have a limit of 9 or 10 but you would need to check with manufacturers instructions.
Research since the Philpott's fire has highlighed that children can sleep through communal fire alarms in the hallway, so having one in each room for them is a must.

There would be nothing left of you to sleep...
You may be forgetting that we're talking about BAS here - he might still be typing away, asking people how they had told LABC that they would satisfy Part P, after the rest of us had been vaporised

If you are wiring off of a light make sure you have the live feed not the switched. I normally use 1mm 3 core for smoke alarms. have a look at the Aico website they have a lot of useful information. http://www.aico.co.uk/

We usually fit a heat detector in the kitchen, and in any room with a wood burning stove. Then a smoke within 5m of any bedroom door. And one at the bottom of the stairs. I believe if the property is to be rented out or holiday let then one in each bedroom is also a recommendation.
Ah - but will I have the endurance to collect on my insurance?You may be forgetting that we're talking about BAS here - he might still be typing away, asking people how they had told LABC that they would satisfy Part P, after the rest of us had been vaporised
