I've had three quotes - discounting the most expensive for various reasons. Arrow Insulation are based in Poole and have good reviews, Max Energy have fewer reviews (but still fairly good) - Arrow is the cheapest by £200 quid. Anyone used either and have horror stories about them - I'm a little on the fence with Arrow as they also offer spray foam insulation which I'd always read was dodgy. It's for a 150sqm bungalow and getting the bonded balls.
(I am aware of the general issues with CWI - the house is very unexposed).
Not heard of those but I was an installer back in late 80s so I'm well out of touch with how things are now.
Back then the spray foam/balls didn't have a great reputation if I recall?
We used a treated mineral fibreglass system. The other big player was using rockwall mineral.
Like I say, things probably have moved on since then so good luck.
BBA accredited system is the way to go. Graphite coated, bonded poly beads were the best thermal performance when I had mine done in 2014.
