‘Grey belt’ loophole opening swathes of countryside to development, new report reveals

A NEW report published today by the London Green Belt Council and CPRE Hertfordshire, reveals the scale of damage being done to the countryside around London by the government’s ‘grey belt’ policy.
The report exposes a falsehood at the heart of one of the government’s flagship policies. In its 2024 election manifesto, Labour said it was ‘committed to preserving the Green Belt’, pledging not to change its ‘purpose or general extent’ says CPRE Herts.

A spokesperson said: “Despite assurances that development on ‘grey belt’ sites in the Green Belt would be confined to the likes of disused car parks and derelict petrol stations, the report shows that no part of the protected Green Belt landscape is safe from development.
Last year 89% of the 35 applications to build on Green Belt land in Hertfordshire were on sites developers claimed were ‘grey belt’. Over 80% of planning appeals in the London Green Belt between February and December 2024 were permitted on ‘grey belt’ grounds – more than twice the proportion that would normally have been granted on any basis.
Commenting on the situation, a KC has said that it is ‘virtually impossible’ to contest such applications, after what is ‘a seismic reversal’ of policy applying to ‘hundreds and hundreds of sites across the country’.
Developers are racing to exploit this opportunity.
However, as the new report reveals, the definition of ‘grey belt’ is so broad that it allows for development in the Green Belt with little or no restriction.
Councils are being forced to reclassify formerly protected land as ‘grey belt’. The report finds that most of the Green Belt opened to development in this way is good quality countryside and agricultural land. The report gives concrete examples of where this has happened.
The report concludes that the government sees the Green Belt as having little economic value unless developed and warns that if this policy is not challenged, no part of the Green Belt will be safe from development.
The report shows that this sacrifice of Green Belt is unnecessary since there are over 1.4 million homes already with planning permission since 2017 which have yet to be built. In addition, since a similar number could be accommodated on previously developed brownfield land.
“A recent poll by More in Common, commissioned by CPRE, shows a strong public appetite for building on brownfield sites, with an overwhelming 86% of people considering Green Belt protections important”.
I wonder why the Labour government are struggling to build 1.5 million homes when this report says: "...this sacrifice of Green Belt is unnecessary since there are over 1.4 million homes already with planning permission since 2017 which have yet to be built." Given that I and others banged on endlessly about land banking and Viability Assessments prior to the general election, it would seem odd that Starmer's government have failed to deter the anti-competitive practice of land banking? Land banking sees large house building firms pay over the odds for land and then sit on it for years. It helps to keep the smaller builders at bay and is used in Viability Assessments to reduce the number of affordable housing units. Yet the Labour luvvies prefer to destroy the Green Belt to serve their big business donors.
Also, economists like Liam Halligan in his book Home Truths argued that council tax should be levied on housing schemes granted permission that are not built after 18 months and then the council tax escalates each year thereafter. No such policy has even been suggested by Labour government ministers, but instead prefer to concrete over the Green Belt to enrich property developers.
Dear Jasper, those asylum seekers not in hotels or army barracks are housed in the very worst end of the private rented sector. Private property developers are selling new homes to buy to let landlords or selling large numbers of units off-plan to foreign investors such as in Hong Kong, Malaysia, Singapore and Russia.
Grey belt is a lie. It was a lie to get them elected. Greed is the only thing destroying our green and pleasant place.
