"Hi Pete

Standardly to fit x2 air bricks with connection vent to internal skin you would be looking at somewhere between £300/£350 but depends on what’s involved internally with heights flooring etc."

"It depends on where they are, how many you need and what type your looking for, plastic is cheaper to buy but clay looks better however it’s more expensive maybe around £80 an air brick to install"
