Planning and Infrastructure Bill

Debate between Baroness Thornhill and Lord Carlile of Berriew

Committee stage
Tuesday 9th September 2025 Lords Chamber

[Lord Carlile of Berriew (CB)]

My Lords, I share the aspiration that we should build sufficient affordable housing in order to house those who need it. I do not propose to repeat what has been said in the three excellent speeches we have heard so far in this debate. I want to turn to a particular issue, with which I hope that the Minister who replies will agree.

One of the ways in which we ensure that affordable housing is built in sufficient numbers is to ensure that the contractual relationship between builders and the councils that give them planning permission is a fair one and does not give undue advantage to the contractors. It has not always been the case that that is so; indeed, there are very recent examples, and I will refer to one very major one.

Some years ago, one of the things I did in my legal life was act as a part-time chair of the Competition Appeal Tribunal, the UK’s anti-trust court. One of the cases on which I sat and gave judgment was a case in which a number of household-name builders had entered into cartel arrangements in order that it was ensured that one of them would win each contract. It was so endemic in the building system that an academic, who I will not name, from a respectable university, which I will not name, wrote a book on how to enter into these cartel arrangements. He did not do the builders much good, because the tribunal which I was chairing fined them a very large amount of money, each related to their world turnover.

They have not learned their lesson from that Competition Appeal Tribunal case. This year, a group of the largest housebuilders in the UK have agreed to a series of legally binding commitments to ensure that they are acting lawfully and to prevent anti-competitive behaviour. They have done that following an investigation by the Competition and Markets Authority—the CMA. I should say to your Lordships that the CMA took a very pragmatic view and did not make a finding that they had been cartelists. I will leave it to your Lordships’ judgment as to whether that was the case or not, under the parliamentary privilege that I have, by telling you what the housebuilders have agreed to.

They made the following commitments to the CMA. The first was not to share competitively sensitive information with competitors, specifically including the prices for which houses are to be sold. If you are a builder, you do not need to make an agreement with the CMA to know that you should not share competitively sensitive information in a competitive contract situation. They then agreed to support the Home Builders Federation and Homes for Scotland to produce guidance on information exchange for the housebuilding industry. Ditto what I said about the first commitment. They further agreed—I am very pleased that they did—to pay £100 million in aggregate to programmes supporting the construction of affordable housing in the UK. Somebody will have done a calculation of how much they had gained from their anti-competitive agreements, and I have no doubt that the £100 million was a conservative—with a small “c”—estimate of the gain that they had made. Then they decided, generously, to introduce enhanced in-house compliance measures and training programmes, no doubt to deal with corruption among individuals within the industry.

Given that case and the one I mentioned earlier, surely one of the most important things—I am sure that the Government will agree with this—is that we should be alive to the risks of corruption in the building industry, so that housing is built without giving the housebuilders money which they do not deserve and have not earned legitimately.

[Baroness Thornhill (LD)]

I have a meeting with them next week; perhaps the noble Lord, Lord Carlile, would like to join me.

[Lord Carlile of Berriew (CB)]

I thank the noble Baroness for the invitation but, looking at the parliamentary programme for next week, I suspect that I am going to be here for about 11 hours a day.
