We have now been handed our 8th document in as many years. The tilted balance in the NPPF has see-sawed with the political priorities of the day, warping the playing field beyond the political, practical and financial capacities of many local authorities and creating uncertainty for the development industry.
The new Labour Government, frustrated by the slow pace of change in the economy, is accelerating this process - it has already forced every council onto the upward revision of the Standard Method for calculating housing need, abolishing any discretion to depart from it. The new NPPF is a clear indication of this centralising tendency, coming after increased call-in powers and in advance of a national scheme of delegation and Mayoral call-in.
The new NPPF is no longer simply "a material consideration" to be weighed alongside the primacy of the Local Plan. It is now of "critical importance", and any inconsistency between a Local Plan and the new National Development Management Policies will be decided in the latter's favour. The balance of power has shifted in the Government's favour: fewer, larger authorities - City Mayors and Combined Authorities - will apportion growth through 25-year sub-regional plans, sitting beneath a now pre-eminent set of national policies.
The default "Yes"
The NPPF has been dramatically restructured, so much so that it looks nothing like its previous eight incarnations. We now have national policies, each with its own specific code, directing either plan-making or decision-making - including new instructions for LPAs not to wait on late consultee responses or over-consult without good reason, though the wording is broad enough that this is unlikely to change behaviour much in practice.
That said, it is not as if the system was labouring under a nationally directed "Default No" until now. This is a nudge, not a revolution.
So, what has actually changed?
Housing
The tilted balance of weighing benefits and harms, along with the question of whether a plan is up to date, remains in place. In some respects, the balance has shifted in favour of the proposer: where there is no up-to-date plan and the proposal complies with the Framework, it must now be positively determined "without delay".
There is now also a broad range of categories setting out when development outside a settlement boundary is acceptable. Where a proposal does not fit within any of these categories, the burden of proof flips, and benefits must "substantially outweigh the adverse effects, including to the character of the countryside and in relation to promoting sustainable patterns of movement."
For most unallocated proposals around settlements, the criteria have changed: sites must now be "physically well-related" to an existing settlement. This opens a whole new concept in planning that will be argued over at appeals and in the courts - is my site a Paragraph S5j site or not?
Another key change relates to the weight applied to benefits. The new NPPF identifies several matters that attract "substantial weight" in the planning balance, and this now includes the provision of new homes.
Density and development around train stations
This is the most eye-catching of the changes picked up by the press, with minimum densities being prescribed for fast-track development. Unsurprisingly, it's more nuanced than the headlines suggest.
The policy only applies to sites within 800m "reasonable walking distance" of "well-connected" stations that fall within the top 80 travel-to-work areas in England. Whether a site benefits will depend on an alchemy of statistical and qualitative interpretation. Where such sites fall within the Green Belt, however, they will now likely be prioritised for release.
Once you've navigated that alchemy and concluded your site falls within the scope of this policy, minimum densities of 35 dwellings per hectare will be required where there are at least two services per hour, rising to 45 dph where there are more. Releasing such land from the Green Belt no longer requires exceptional circumstances to justify it, and the colour will drain away from many faces in the Home Counties as they realise Grey Belt has not just survived but thrived in the new document.
Economy
The NPPF has gone backwards here. The prizing of innovation and productivity, particularly in fields where the UK can be a global leader, was clearly set out in the 2024 version but did not make it into the new one.
That said, the UK's 2025 Modern Industrial Strategy is specifically referenced, and new Local Plans must respond to what it says about key locations vital to UK strategy. Sectoral Spatial Plans are also referenced, providing a clearer link between the NPPF and national strategies relating to, for example, energy and transport.
Universities are conspicuously absent from the NPPF, and, by interpretation rather than explicit definition, can be assumed to fall within "Public Service Infrastructure". For a document that claims to prize the innovation economy, these omissions are surprising, even as major freight and logistics proposals now get an easier run where there's a proven need.
Rural planning and agriculture
While rural affairs remain something of a Cinderella within the planning system, the new NPPF is explicit in its support for farm and agricultural modernisation that brings benefits in food production, animal welfare or the environment. This is a welcome addition.
Environment
There does not appear to be any weakening of environmental protections. In fact, there is some strengthening, particularly around heritage.
Protections for non-designated heritage assets have increased, moving beyond a simple balancing exercise to one involving the weighing of benefits. Any harm to a designated asset is now "a matter of considerable importance and weight", aligning the NPPF with case law (Barnwell Manor). We also now have "impacts" rather than "effects", signalling a small but telling shift in language. There is greater emphasis, too, on the "substantial weight" that should be applied to measures that improve building sustainability and tackle climate change. This is, however, tempered slightly for listed buildings, where such measures attract "important" rather than "substantial" benefits. Landscape protections have been tidied up and reframed too, with a new addition covering tranquillity and dark skies policy.
There are also clear new policy directives on renaturalising river channels and uncovering culverts, with definitions of essential infrastructure updated to reflect the UK's increasingly diverse energy generation mix.
What does this all mean?
Will the planning process speed up?
It's telling that the word "duplicate" or "duplication", which appeared once in the last NPPF, now appears eight times in the new one. While we should now have more tightly written Local Plans to read, LPAs are grappling with a brand-new plan-making system alongside a new NPPF that has introduced several new policy concepts and structures - all of which will need to be tested through litigation in the months and years ahead.
The emphasis on approval without delay and on avoiding unnecessary consultation is welcome, but it isn't new. These good intentions are unlikely to significantly penetrate what is arguably one of the most complex systems of land use and development control in the world. Don't hold your breath.
New areas to argue about
The NPPF introduces new tests and definitions, and on first reading there are many areas where fresh litigation at appeals and in the courts seems inevitable. Paragraph S5j sites and the complexity of development around train stations are two obvious candidates, but there are others, including Policy HO13(4): does this policy protect an emerging Local Plan against all major speculative development, or does it apply only to early applications within a mooted strategic site?
Opportunities to pursue
The presumption in favour of sustainable development is stronger for well-performing sites outside a settlement boundary. The new Policy S5 now extends this presumption to unmet employment needs. The substantial weight now given to new homes is welcome, and the new Framework should move the dial closer to successful determination - locally, and particularly at appeal.
However, the lack of alignment between the ambition of the NPPF and other Government strategies - particularly around the knowledge economy and industrial strategy - is an irritation. Commercial proposals that are strategic in scope and align with UK industrial strategy will thrive under the new NPPF, but we may all need to work harder, particularly in the early stages of plan-making, to ensure some of the most dynamic parts of our economy are properly considered.
The Government's plan is now clearly leading the system. How soon can everyone else follow?
