My Lords, I will intervene briefly. I declare an interest as a chartered surveyor with some involvement in the development process.
I want to speak to the factor that links Amendments 71 and 94 and follows on from what the noble Lord, Lord Young of Cookham, has just said. I have been in the past a technical operator of the dark arts of development appraisal. I would be much less charitable than the noble Lord, Lord Stunell, in my comments about exactly what goes on here; for instance, how land values under option agreements are arrived at and how, with a click of a mouse on a proprietary development appraisal computer package, the matter can then adapt to a viability test for the local authority’s community infrastructure levy or Section 106 contribution purposes. Noble Lords would be astounded at the way in which a yield change here and a cost base there, as well as the adaption of a timeframe or the alteration of a contingency allowance—I mention just a few means—can be used to alter significantly the entire outcome and colouration of what is claimed on the back of it. Further, all this is done by using the same primary data inputs and, unsurprisingly, there are two factors that developers will never reveal to you if they can get away with it. One is the land value that they paid, coloured as it is by all sorts of associated costs before it gets as far as a planning consent; the second is their construction costs, which are entirely opaque.
Alongside all this and of much longer standing is what I describe as the commoditisation of residential property, which started in the 1990s. It has since financed ever more of the items society wishes to have, in terms of affordable housing, infrastructure, schools et cetera. But that policy has created a consistent and ever more bankable asset within an enhanced lending sector. This results in the very unfortunate situation of driving up house prices and creating a model that is less than satisfactory. Core to this is the issue raised by the noble Lord, Lord Stunell—transparency. Without it, none of this will be demonstrable to anybody, at any time.
