Interesting for a house built in 2006The guy who looked at it said there's existing insulation board in the cavity but that there's still a gap which should be toppped up with the stuff they pump in.
Also the insulation around the crawl space of the attic is not sufficient (only around 4") and he has recommened adding another 8" on top in the crawl space and in the space on top of the converted attic (basically in the attic roof space where the tank is).

Did the house pass building regulations ? Did you get a certificate of compliance with the regs from your building professionals
I guess if it had passed building regs, you wouldnt need to top up the cavity, there shouldn't be any gap anywhere,
There should be a complete uninterrupted envelope of insulation all around the house including the floor
You should deal with the gap, with the priviso that filling cavity gaps completely can be a bad idea in certain circumstances, i.e. it means if the insulation gets wet, it cant easily dry out, causing damp, and making the house colder not warmer
Yeah 12 inches is around 300mm, which is exactly the loft insulation in the UK to meet building regs. Not sure what the recommended loft insulation is in Ireland.
When they built your house 4 years ago, they put in 100mm, very poor, not nearly enough
All I can do is use a proper company to do the work (which I'm doing - I'm getting the work done this week).
