Planning reform is back. Again.
England has a new NPPF, a new Local Plan system, changes to planning committees and a growing push to get more homes built. If you're a developer, investor or property owner, you probably don't want 80 pages of policy explained to you over a coffee that went cold two hours ago.
So, here's what actually matters.
Brownfield is getting interesting
Government policy is increasingly focused on making better use of land we've already developed. That doesn't just mean enormous former industrial sites.
The latest NPPF specifically points towards opportunities including car parks, service yards, lock-ups, underused commercial sites, transport land and regeneration sites. In London especially, that's important.
The next development opportunity might not look like a development site at all. It could be behind a parade of shops, above an existing building, an awkward yard, a tired commercial property, or that car park everyone has walked past for ten years without asking why it needs to be quite so enormous.
Land is expensive. Wasted land is even more expensive.
Housing need has more weight
The new NPPF gives substantial weight to providing homes that meet evidenced local housing needs.
No, this doesn't mean you can now put 47 flats in your back garden because "the Government said we need housing." Planning still has to deal with design, heritage, neighbours, highways, affordable housing, environmental issues and local policy.
But the balance is shifting. Where a site can accommodate more homes sensibly, there is a stronger policy backdrop for making that argument.
Old sites deserve another look
This may be the most commercially important point. If you looked at a site two or three years ago and decided it didn't work, look again.
Planning policy changes. Local Plans change. Nearby precedents change. Housing requirements change. Sites around yours get permission. Sometimes the thing that makes a development viable isn't the site changing. It's the planning environment around it.
That doesn't mean every previously unviable site has suddenly become gold dust. Unfortunately, planning reform hasn't discovered alchemy yet. But previous assumptions shouldn't automatically be treated as permanent ones.
Local Plans are changing
A new Local Plan-making system came into force in March 2026. This matters because Local Plans influence where councils expect development, what kind of development they want and how intensively land might be used.
For landowners and developers, that can have very real consequences. A policy designation buried in a PDF somewhere on a council website can eventually translate into a fairly substantial difference in land value.
Which is why planning should ideally be investigated before you buy, rather than after you've exchanged contracts and started asking everyone whether eight storeys might be "a bit ambitious".
Planning committees are changing too
From 31 October 2026, reforms change aspects of how planning applications are delegated and determined, alongside requirements around committee size and member training.
The intention is greater consistency. We'll reserve judgement on whether the words "planning system" and "consistency" finally become comfortable appearing in the same sentence.
For applicants, understanding how an application is likely to be determined remains part of understanding its planning risk.
The biggest change isn't actually a rule
For us, the interesting part isn't any single paragraph of the NPPF. It's the direction of travel.
Government wants more homes, better use of existing land, more up-to-date Local Plans and a planning system that delivers development more efficiently. That creates opportunities, but planning reform doesn't turn a bad scheme into a good one.
A site still needs a credible relationship between planning, architecture, viability, technical constraints and, ultimately, what somebody can actually build.
That's why the best time to think about planning usually isn't when you've finished designing the building. It's at the beginning.
Before you buy the site, understand the site
For developers considering an acquisition, there are some fairly basic questions worth answering first.
What can realistically go here? What's been approved nearby? What's been refused? What does the planning history tell us? Could the site accommodate greater density? Is the proposed use right? What are the obvious constraints? Would Pre-App help? And importantly, does the development actually stack up?
Spending a relatively small amount answering those questions before acquiring a property can be considerably cheaper than discovering the answers afterwards.
We've seen enough sites to know that "we'll sort the planning out later" is rarely the beginning of a relaxing story.
