The Rulebook for Planning in England
NPPF stands for National Planning Policy Framework. Think of it as the Government’s rulebook for planning decisions across England. It sets out the principles that local councils must follow when they decide whether to grant or refuse planning permission, and when they draw up their own local plans.
It doesn’t replace your local council’s planning department. But it sits above it. When a planning application is decided, the council has to take account of both their own local plan and the NPPF. Where the two conflict, or where the local plan is out of date, the NPPF takes over.
In simple terms — the NPPF tells planners what they must do, and when they can say no.
Why Does It Keep Changing?
The NPPF has been updated several times since it was first introduced in 2012. Each update reflects the Government’s priorities at the time — and right now, those priorities are firmly focused on building more homes.
England has a chronic shortage of housing. The Government has set a target of 1.5 million new homes over this Parliament. To hit that number, the planning system needs to say yes more often, in more places, and more quickly than it has been doing.
The latest version of the NPPF — updated in August 2026 — is designed to make exactly that happen.
The planning system has been one of the biggest barriers to building homes in this country. The revised NPPF is a deliberate attempt to change that — and for landowners, it opens up possibilities that simply didn’t exist before.
The Presumption in Favour of Development
One of the most important principles in the NPPF is what’s known as the “presumption in favour of sustainable development.” This sounds technical, but it means something very practical.
If a local council cannot show that it has enough land in the pipeline to deliver the homes its area needs over the next five years — what’s called a five-year housing land supply — then the normal rules loosen considerably. Instead of the applicant having to prove why development should be allowed, the council has to prove why it should be refused.
A large number of local authorities across England currently cannot demonstrate that five-year supply. Which means, right now, there is a real and genuine window of opportunity on a great many sites.
Brownfield Land — Easier to Develop Than Before
The NPPF has always supported the idea of building on previously developed land before greenfield sites. What the latest version does is make that support much stronger.
Previously developed land — often called brownfield land — now has what the Government describes as a “brownfield passport.” Well-designed schemes on brownfield land within towns and villages should, in principle, be approved. Councils who refuse compliant brownfield applications now face a much tougher time defending that decision at appeal.
The definition of brownfield has also been widened. Car parks, storage yards, depots and similar sites all now qualify — which brings a wider range of land into play than many people realise.
The Grey Belt — a New Way Through the Green Belt
This is perhaps the biggest change of all. For decades, the Green Belt has operated as an almost total barrier to development. To build on Green Belt land, you had to prove “very special circumstances” — an extremely high bar that very few applications could clear.
The latest NPPF introduces a new concept called the Grey Belt. This covers Green Belt land that is either previously developed, or that makes only a limited contribution to the purposes the Green Belt is supposed to serve — preventing towns from sprawling outwards, stopping settlements merging into each other, and so on.
The scrappy, underperforming bits of Green Belt — an overgrown field next to an industrial estate, a disused yard on the edge of a village — these are the kinds of sites the Grey Belt concept is designed to capture. And for those sites, the very special circumstances bar has been removed entirely.
If you own land in or near the Green Belt that has previously been dismissed as undevelopable, it is genuinely worth a fresh look.
Land Near Railway Stations
The most recent change — introduced in August 2026 — is specifically aimed at land within walking distance of well-connected railway stations.
Under the new rules, homes built within approximately 800 metres of a well-connected station now receive a default yes from the planning system, even if that land is within the Green Belt. The logic is straightforward: living within walking distance of a train station is one of the most sustainable locations there is.
For landowners within a ten-minute walk of a commuter station — whether in a town, on the edge of a settlement, or even in the Green Belt — this represents a significant and potentially time-sensitive opportunity.
What Does This Mean if You Own Land?
The honest answer is that it depends on your land. Not every site will benefit from these changes. But a great many will — including sites that would have been dismissed out of hand even two or three years ago.
The key questions are whether your land is in an area where the council is struggling to demonstrate its housing supply, whether it might qualify as brownfield or Grey Belt, and whether it sits within walking distance of a station. Any one of those factors could open a door that was previously closed.
At ASTON MEAD, we’re already helping landowners across the South East and South West make sense of what the revised NPPF means for their sites – and importantly, land that once had limited prospects now has a real chance of success.
If you own land and want to know where you stand under the current policy environment, we would welcome the chance to take a look and talk through your options. There’s no cost or obligation – just get in touch with our team
