The government’s consultation on NPPF reforms, published 17 December 2025 and closing in March 2026, carries a characteristically direct framing: back the builders, not the blockers.
Three proposals matter most for pipelines. A presumption in favour of permission near stations and in urban high-rise zones. Simplified biodiversity net gain for SMEs. And a raised Building Safety Levy exemption threshold.
Why NPPF planning reform matters right now
Planning delay is consistently among the most cited drags on UK practice workload — it appears in RIBA’s own survey commentary alongside fee pressure and economic uncertainty. Anything that changes consent timing therefore changes resourcing, not just viability.
The presumption in favour near stations is the most consequential for site strategy. If it survives into policy, it shifts the economics of transit-adjacent and urban high-rise sites, which reshapes where developers look and therefore where consultants need capability.
Simplified biodiversity net gain for SMEs addresses a genuine proportionality problem. BNG compliance costs are far less burdensome at scale than on small schemes, and the current position has deterred smaller developers disproportionately.
Key takeaways
- Proposals include a presumption in favour of permission near stations and in urban high-rise zones.
- Biodiversity net gain would be simplified for SMEs.
- The Building Safety Levy exemption threshold would be raised.
- Planning delay is a top-cited drag on UK practice workload.
- Changes in consent timing alter resourcing as much as viability.
What this means for planning consultants, architects and developers
For planning consultants, reform consultations generate concentrated demand — policy interpretation, site reassessment, revised submissions — followed by quieter periods. Capacity that flexes is worth more than capacity that is simply large.
For architects, the resourcing effect is the familiar one. Faster consents do not reduce work; they move it earlier, often into a quarter already committed to other projects. A pipeline that accelerates is as disruptive to resourcing as one that slips.
For developers, site strategy may need revisiting. If transit-adjacent and urban high-rise sites become materially easier to consent, land already held may be worth more and sites previously discounted may re-enter consideration.
Acceleration disrupts too
Work pulled forward lands in quarters already committed. Faster is not automatically easier to resource.
Flex beats scale
Reform creates bursts of consultancy demand. Flexible capacity captures more of it than headcount does.
Reassess held land
A presumption in favour near stations changes which sites are worth progressing.
Pipeline forecasting under policy change: spreadsheets, point tools or one system?
Policy-driven timing changes are exactly the scenario static forecasts handle worst.
| Capability | Spreadsheets | Separate point tools | Quantim |
|---|---|---|---|
| Re-forecast on timing change | Manual rebuild | Partial | Immediate across the portfolio |
| Acceleration scenarios | Rarely modelled | Limited | Scenario planning built in |
| Capacity vs consent timing | Two separate views | Disconnected | One model |
| Site-level viability tracking | Separate file | Hard to join | Linked to project data |
| Flexible resourcing planning | Headcount only | Limited | Capability-aware |
How Quantim helps
Planning delays are a top-cited challenge in RIBA’s own surveys, and planning acceleration creates the mirror-image resourcing problem. Quantim’s project forecasting and resource planning let firms re-model capacity immediately when consent timing shifts in either direction.
The value is responsiveness rather than prediction. Nobody can forecast a planning decision; what firms can do is see, within minutes, what a decision means for everything else they have committed to.
- Tag pipeline projects by planning dependency so policy-sensitive schemes are identifiable.
- Model both acceleration and slippage — reform creates risk in both directions.
- Plan flexible capacity for the consultancy demand bursts that policy change generates.

Checklist for practice leaders
- Tag every pipeline project with its planning dependency and sensitivity.
- Model a three-month acceleration on the two largest policy-sensitive schemes.
- Reassess held land against a presumption in favour near stations.
- Review biodiversity net gain exposure on smaller schemes.
- Check Building Safety Levy threshold implications across the pipeline.
- Agree which consultancy capacity can flex to absorb demand bursts.
Frequently asked questions
What are the 2026 NPPF changes for developers?
The consultation published in December 2025 proposed a presumption in favour of permission near stations and in urban high-rise zones, simplified biodiversity net gain requirements for SMEs, and a raised Building Safety Levy exemption threshold. Together these are aimed at consent speed and at reducing disproportionate burdens on smaller developers. The proposals were reported by The Construction Index's coverage of the planning reform proposals.
How does planning reform affect construction project timelines in the UK?
Both by shortening consent periods for qualifying schemes and by introducing a period of interpretive uncertainty while new policy beds in. For delivery businesses the practical effect is timing volatility rather than straightforward acceleration: some schemes move earlier, others stall pending clarity. That makes pipeline re-forecasting capability more valuable than any particular prediction about outcomes.
Is faster planning good news for architects and consultants?
Broadly yes, commercially, but it creates a resourcing problem that is less discussed. Work pulled forward does not reduce annual workload; it relocates it into quarters that were already committed. Practices that only model slippage, and never acceleration, tend to be caught out when several consents arrive together.
Planning reform changes when work happens more than whether it happens. The firms that handle it well are those who can re-model capacity quickly in either direction. Explore the features and benefits of Quantim to see how project forecasting and resource planning respond to change.
