Debate

Grey Belt Land: Definition and Application

Contribution

It is a pleasure to serve under your chairmanship, Dame Siobhain, and to take part in this debate about the definition and application of so-called grey-belt land. I thank my right hon. and learned Friend the Member for Kenilworth and Southam (Sir Jeremy Wright) for securing this important debate and for his excellent opening speech. The first mention of the Government’s novel term “grey belt” came in their 2024 election manifesto. Labour MPs campaigned on a promise to release “lower quality ‘grey belt’ land”, which they described as scrub land, disused car parks and old petrol stations, alongside a commitment to “preserving the green belt”. Those policies were part of an overarching pledge to build 1.5 million homes by 2029. Just over two years later, however, and almost halfway through this Parliament, we are left wondering where it all went so wrong, because the Government are not releasing low-quality land, they are not preserving the green belt, and they are nowhere near their stated target of building 1.5 million homes. How could that be the case, given that they have such a mammoth majority with which to make it happen? The answer is that the concept of the grey belt was a fiction from the start. It is, and always has been, a thinly veiled conceit. As my right hon. and learned Friend the Member for Kenilworth and Southam and the hon. Member for Taunton and Wellington (Gideon Amos) highlighted, the grey belt has been talked up as low-quality land made up of disused car parks, but behind the façade it is usually found to be prime green-belt land. That is not just a political point; it is a factual one. As my right hon. and learned Friend the Member for Kenilworth and Southam pointed out, research from the Campaign to Protect Rural England has shown that by December 2025, of the 13 developments of 10 or more homes that had been approved by Government planning inspectors on so-called grey-belt land, 88% were earmarked for building on previously undeveloped countryside. To be clear, that is not disused petrol stations or low-quality land, but our local and valued countryside. What is worse is that those developments made up more than 90% of homes granted planning permission on allegedly grey-belt sites. With so much grey belt looking far more like green belt, at least according to the Government’s own NPPF definitions, what is the true definition of grey belt? For the sake of our concerned constituents, perhaps the Minister can explain what definition inspectors are working to, as it is clearly not the same as the one that has been codified and publicised. Even if the Government stuck to their stated definition of grey belt and refused to waver from it, we would still be left without a clear route to their target of 1.5 million homes. As the hon. Member for Woking (Mr Forster) pointed out, that is because the Government have done nothing to make development on previously developed land any more viable than before; indeed, they have made it worse. The Government have made an effort to increase and swiften planning permissions, but there has been no corresponding effort to make proposed sites more viable. The Planning and Infrastructure Act 2025 did much to silence the voices of democratically elected local councillors in order to push planning permissions thicker and faster through the system, but it did nothing to make building new homes more affordable. There has been no recognition at all of the barriers—largely been created by the state—that have been thrown in the way of developers. The top-down housing targets that our rural councils were saddled with, representing an increase of up to 487% in some cases, make sites no more viable; they just put more pressure on local planning authorities to grant more permissions. Superficially, supposedly grey-belt sites may be an attractive prospect for development because there are likely to be fewer complications than anticipated for brownfield development. However, when supposedly grey-belt sites are released, they might not deliver substantially more housing because the Government will still have done next to nothing to improve the site’s viability. The Government have imposed the golden rule of at least 15% affordable housing above local policy requirements, up to a 50% cap. Sites still come with a biodiversity net gain requirement; they still require landfill tax payments, they still have to meet building regulations and soon they will be subjected to the building safety levy. After a site’s release, some building will likely take place. But given the Government’s unwillingness to help to make brownfield sites more viable, we will be left with the lamentable scenario of losing chunks of green-belt land without getting anywhere near the required housing numbers. As the Government hide behind their own nebulous grey belt definition, they chip away at our local green belt without making a dent in their 1.5 million homes target. That is not progress; that is failure. The statistics show it too. It is estimated from the energy performance certificate lodgements data that the Government oversaw the net addition of just 392,400 homes between 9 July 2024 and 14 June 2026—a paltry 26% of their manifesto target. Far from using the green belt to meet their targets, they are ditching its protections and removing its special place in our communities, all for the sake of plodding progress towards an increasingly distant target. I am pleased to say that there is a way out of this malaise that dually serves to protect the green belt and build more houses. Instead of sham terms and shady insincerities, the Opposition stand for a genuine brownfield-first approach to building. We on this side of the Chamber will not just pay lip service to brownfield development but prioritise it and make it easier. It can and will be done. We all want to see more homes built, but they must be built in the right places, with local understanding and on brownfield sites first. That is the common-sense answer. It is the Opposition’s answer, and it is an achievable outcome. Further research from the CPRE shows that a large proportion of the Government’s lofty housing target could be swiftly met using brownfield land that already has planning permission. The CPRE estimates that up to 1.41 million homes could be built on existing brownfield land in England, based on data from local planning authorities’ brownfield land registers up to 2024. The same data shows that, as of September 2025, more than half of those sites had planning permission already. The 1.41 million amounts to 93% of the Government’s manifesto pledge. Perhaps when considering this, the Secretary of State may change her mind again and once more view 1.5 million homes as a viable goal rather than a “stretch target”, as she described it at the weekend. The Government must change course. The returning Secretary of State has already U-turned on her disastrous and costly programme of local government reform. Perhaps the Minister can use his platform to join Conservative colleagues and stand against concreting over our green belt. I hope he uses his time to do exactly that. I hope he also takes the chance to not just acknowledge but to respond to the concerns shared by hon. Members and take a better and fairer approach to our green belt.
