Construction (Design and Management) Regulations 2015

My Lords, I have just one brief question for the Minister on the regulations. Paragraph 20 of the impact assessment refers to financial impact. It states that the deemed approach—which is much the better one, I am sure—will cost £1.3 million to homeowners and £4.6 million to contractors. All my experience is that costs to contractors get handed on to the people for whom they are providing their services, so how do we know that the £4.6 million will not simply be handed on to the homeowners to whom the services are being provided? How can one make that distinction?
