Even anecdotally, do the witnesses have information on this? I am going in the direction of economies of scale. If someone has to mobilise on a one-off site, that obviously incurs more costs than a contractor arriving where he may be able to do a semi-detached block or a terrace. I am wondering what is the breakdown of the type of house impacted.
