  1. GRB-01True

    “The green belt covers more of England than all the land that has been built on.”

    Confirmed: in March 2025 the green belt covered 1,633,220 hectares, about 12.5% of England. Only about 9% of England is in developed use.

    Developed land means things like homes, roads and factories. Even the wider 'built-up' area, which also counts gardens and grassy spaces in towns, is about 11% of England. The biggest green belt is around London. It covers 508,080 hectares, about three times the size of London itself (157,330 hectares).

    “was estimated at 1,633,220 hectares, around 12.5% of the land area of England”

  2. GRB-02Mostly false

    “Most green belt land is scrubland or wasteland, not real countryside.”

    Most of it is open, undeveloped land. In 2022, 93.1% of green belt land was undeveloped and 65.0% was farmland. Forest, open land and water made up another 18.9%.

    'Green belt' is a planning label. It is not a description of what the land looks like. About 6.8% of it is built on, and over half of that is roads and other transport. Homes cover just 0.3%. Since December 2024, councils must check their green belt for weaker 'grey belt' land, such as old built-on sites, where building can be allowed. The official green belt figures do not yet say how much grey belt has been found.

    “An estimated 93.1% of the green belt was undeveloped land in 2022. This land was primarily used for agriculture (65.0% of all green belt land).”

  3. GRB-03Mostly true

    “A typical home in England costs about eight times what a typical worker earns in a year.”

    Close: in 2025 a typical home in England cost £300,000. That is 7.6 times the typical full-time worker's yearly pay of £39,300.

    7.6 is the best (lowest) figure since 2015. Homes have got a little easier to afford since 2021: across England and Wales, pay rose 25% while house prices rose 5%. It varies a lot by place. A home costs about 10.6 times pay in London, but 5.0 times in the North East. The statistics office uses five times pay as a rough line for 'affordable'.

    “the median average home in England, at £300,000, cost 7.6 times the median annual average earnings of a full-time employee (£39,300)”

    “Building lots more homes would make housing affordable.”

    Partly. More homes do push prices down: a model used by the government says 1% more homes means prices about 2% lower, if nothing else changes. But from 1991 to 2016, rising incomes pushed prices up far more than new homes pulled them down.

    A 2018 government analysis looked at 1991 to 2016. England's number of homes grew by about 20.6%, which on its own would have cut prices by about 40%. But total household income, after rising prices are taken into account, grew 75%. On its own that would have pushed prices up by about 150%. Falling interest rates pushed prices up too, but the analysis could not say by how much. The authors say these are rough estimates to treat with caution. England now adds less than 1% to its homes each year.

  5. GRB-05True

    “England is building far fewer homes than the government's target of 1.5 million.”

    Confirmed: an official estimate says 437,900 extra homes were added from 9 July 2024 to 20 September 2026. Reaching 1.5 million in a five-year Parliament means about 300,000 a year, but England is adding about 200,000 a year.

    In 2024-25 England added 208,600 homes, 6% fewer than the year before. The early estimate for 2025-26 is 196,900. The recent peak was 248,590 in 2019-20. These are 'net' numbers: new homes, plus conversions, minus homes knocked down.

    “we estimate that 437,900 net additional homes have been delivered in England between the start of Parliament, on 9 July 2024, and 20 September 2026”

  6. GRB-06Mixed

    “There is enough brownfield land to build all the homes England needs, so the green belt can be left alone.”

    This is disputed. The government says brownfield registers (council lists of old building sites) do not hold enough sites for the homes needed each year. The countryside charity CPRE says there is room for many homes on brownfield land.

    Brownfield means land that has been built on before. In 2018 CPRE said council areas with green belt had enough brownfield land for over 720,000 homes. The government wants 1.5 million homes in this Parliament. It says many brownfield sites cost too much to build on or are in the wrong places. Brownfield is already used a lot: in 2021-22, 54% of new homes in England were built on land that had been built on before.

    “there are simply not enough sites on brownfield land registers to deliver the volume of homes that the country needs each year”

  7. GRB-07Mostly false

    “The green belt is shrinking fast as it gets built on.”

    Not really. In the year to March 2025 it shrank by 660 hectares, just 0.04%. It is about the same size now (1,633,220 hectares) as in 2007 (1,632,900 hectares).

    The green belt changes size when councils redraw its edges in their local plans. Between 2012 and 2021 it shrank by about 1.2%. Then in 2021-22 it grew by 24,580 hectares, mostly because Northumberland drew detailed green belt lines for the first time. Some land inside the green belt also gets built on while keeping the label: from 2019-20 to 2021-22, 71.5 square km of undeveloped green belt land was built on, and 7.6 square km of that became housing. The latest figures stop at March 2025, soon after the December 2024 rule changes, so later years may look different.

  8. GRB-08Mostly false

    “Developers are already concreting over the green belt, with lots of new homes built on it.”

    Not in the latest official figures. In 2021-22 only 2% of new homes in England were in the green belt, and about half of those (51%) were on land that had been built on before.

    Homes cover just 0.3% of green belt land. Across England, 54% of new homes in 2021-22 were built on previously developed land. These figures are from before the rule changes of December 2024, which aim to allow more building on parts of the green belt, so the share may rise.

  9. GRB-09Mostly false

    “There are over a million empty homes in England, so there is no need to build on the green belt.”

    The number is too high. In September 2025 council tax records showed about 754,000 empty homes: 542,000 counted as empty, plus 212,000 empty homes that did not have to pay the tax. That is about 3% of England's 25.8 million homes.

    Only 153,000 of them were charged the extra 'empty homes premium'. Councils can add this once a home has been empty and unfurnished for more than a year. There were also 268,000 second homes. These have furniture but are nobody's main home. Counting them too gives about 1 million, but they are not empty homes. Even if every empty home were filled, 754,000 is about half of the government's target of 1.5 million new homes.

    “there were 542,000 dwellings recorded as empty for the purposes of council tax as of 10 September 2025”

  10. GRB-10Mostly true

    “Under the new rules, half of all homes built on green belt land must be affordable housing.”

    Often, but not always. The 'Golden Rules' ask for 15 points more affordable housing than the area would normally ask for, up to a top limit of 50%. Where there is no normal target, it is 50%. The government said this would mean 50% in most council areas.

    For example, if an area normally asks for 30% affordable homes, a big green belt scheme would be asked for 45%. The rules cover larger housing schemes in the green belt or on land taken out of it. They do not cover sites already released or approved before 12 December 2024. Builders can ask to give less in three cases, such as very large 'strategic' sites, if they prove the full amount is not possible. Councils can also set their own green belt rules in new local plans. Schemes must also pay for things they need, like better roads and local services, and provide green space the public can use.

  11. GRB-11Mixed

    “The green belt exists to protect wildlife and beautiful countryside.”

    Only partly. Its main official aim is to stop towns and cities spreading outwards by keeping land open for good. Protecting the countryside from being built over is one of its five purposes, but none of them is about how pretty the land is or about wildlife.

    The five purposes are: stop big built-up areas sprawling, stop towns merging, protect the countryside from creeping building, protect the setting of historic towns, and push building onto old city land. England has separate labels for special landscapes and wildlife: National Parks, National Landscapes (once called Areas of Outstanding Natural Beauty) and Sites of Special Scientific Interest. These cover 26.4% of England. Councils are also asked to plan how green belt can help nature and give people access to green space.

  12. GRB-12Mostly true

    “Living near green space is good for people's health.”

    Mostly right: a big review of 143 studies found that people with more green space around them tended to be healthier. But most of the studies show a link, not proof that green space causes better health.

    The 2018 review combined the results of many studies. More green space was linked to lower risk of type 2 diabetes, of dying from heart disease, and of dying early from any cause. It was also linked to lower stress hormone levels and blood pressure. The authors warn that some results come from weaker studies that disagree a lot. The review is about green space in general, not the green belt. Much green belt is farmland, and big new green belt housing schemes must now provide public green space.
