After a robust consultation (20,572 responses were received to the draft NPPF consultation), eight months and one new prime minister later, the government’s proposed revisions to the National Planning Policy Framework (NPPF) have landed.
In the words of top Planorak, Zack Simons: the 2026 NPPF is: “the most powerful, coherent, and quietly revolutionary national planning policy we’ve ever had”.
When compared to December’s consultation draft, what’s changed in the final version? If you want a line by line analysis, Simon Ricketts has provided a tracked-change version here, along with his own commentary.
While there are changes, most of them seem to be tweaks to criteria, rather than wholesale policy pivots. Most significantly:
Rather than provide my own lukewarm takes on the impact of the new NPPF, I’m going to focus today on what the changes mean for LandTech’s customers, and how we’ve been able to adapt the data and the tools that we have to accommodate the changes.
Under new policies (GB3, GB7, and S5), land located within a "reasonable walking distance" - defined as 800 metres (~10 minutes’ walk) - of a well-connected station receives strong policy backing.
Key takeaways for developers include:

How LandTech Helps: The Train Station Data Layer
Our ‘Train Station Connectivity’ layer has been available for several months already. We’ll be updating this layer in the coming days to accommodate the land around the additional stations now picked up by the expansion of the TTWA criteria from the top 60 to the top 80.
We will continue to filter the sites around the most connected train stations to remove land that is subject to ‘red-flag’ constraints such as Flood Zones 2 and 3, and (using the new ‘predictive’ agricultural land classifications), Best and Most Versatile agricultural land.

Policy S4 continues to support development within Settlements by applying the presumption in favour across the board in these areas. Although the final version of the NPPF has included an updated definition of Settlement, which excludes villages that are ‘washed-over’ by Green Belt. For settlements that are not in the Green Belt, this policy now provides an expectation that new developments will be approved. In addition to this, Policy L3 introduces a clear mandate: land within reach of transit nodes must work harder.
The consulted-on targets for density were 40 dph in near stations in settlement boundaries and 50 dph in well-connected areas. These have all been watered down in response to the consultation. The density minimums that apply now are:
This policy shift directly impacts site yield calculations, land valuation models, and gross-to-net developable area assessments.
How LandTech Helps: The New Density Uplift Layer
Launching alongside the new NPPF updates, LandTech’s new Density Uplift Layer allows you to instantly visualise where capacity increases are legally backed by policy. With our new layer, you can identify existing low-density plots or allocated sites where density can be scaled up to 35 dph or 45+ dph in line with Policy S4 and L3.
With National Decision-Making Policies now setting clear statutory expectations across England, ensuring a site passes policy muster at the pre-application stage is crucial.
How LandTech Helps: The New Policy Checker
Navigating complex updates across housing land supply, flood risk, heritage, and Green Belt rules can be time-consuming. LandTech’s new Policy Checker automates site risk assessments against the National Decision-Making Policies:
Automated Red-Flagging: Instantly cross-examine your pipeline sites against policies governing Green Belt Golden Rules (GB8), flood zones (F4-F7), and station proximity rules (S5/GB7).
- Decision Certainty: Evaluate whether an unallocated site meets the criteria for presumption in favor of sustainable development before spending on pre-application advice.
