Most of the attention on planning reform has gone to housing numbers and the framework itself. The quieter change, and in some ways the more significant one for how development comes forward, is the new plan-making system. It reshapes how local plans are produced, and that has knock-on effects for anyone promoting a site.
The headline is a move towards faster, more standardised local plans, produced to clearer timetables and tied more closely to national policy. For developers, the value sits in understanding what that means for timing, evidence and the way transport is treated within the plan.
What has actually changed
The new system sets out a more prescribed route for producing a local plan, with the aim of cutting the years that plans have taken to reach adoption. Plans are expected to follow a tighter, more consistent process, and to sit alongside the revised national framework rather than reinventing policy locally. The intention is fewer bespoke local variations and more predictability about what a plan will require.
For transport, the significance is that more of the assessment moves up to plan-making stage. Where a plan allocates sites, the transport evidence behind those allocations carries real weight. A site with a credible transport case at plan stage starts from a stronger position than one that has to argue everything at application.
The Connectivity Tool enters the picture
One of the more practical additions is the DfT Connectivity Tool, referenced as a way of assessing how well a location is served by different modes. It scores accessibility to services and facilities, which feeds into the sustainability case for a site. TPA has set out how access shapes development in its project experience, and a tool that puts a number on connectivity makes that argument easier to frame, and easier to challenge.
There is a caveat worth knowing. Access to the full tool has not been open to everyone in the way the profession wants, which limits how far private-sector teams can test and adjust interventions themselves. That is likely to change, but it is a live issue for anyone relying on connectivity scores in the near term.
Why this matters at pre-application
The practical takeaway is to engage earlier than the application itself. If site allocations are being shaped through the plan, the transport case wants to be part of that conversation. Getting transport input in at the pre-application stage, and ideally at plan-making stage where a site is being promoted, is the difference between building on an agreed position and arguing from scratch later.
A worked example of the difference
Consider two similar sites competing for allocation. One arrives with a clear connectivity picture, a transport strategy that fits the emerging plan, and evidence that sustainable access is realistic. The other leaves transport to the application stage. Under the new system, the first site is far easier for a plan-making authority to allocate with confidence, because the evidence is already there and consistent with national policy. The second carries more risk, and risk is what slows allocations down.
What developers should do now
Three things are worth acting on. Track where the relevant local plan sits in the new process, because the timetable is more predictable than it used to be. Prepare the transport evidence to match the standard the plan will expect, rather than a lighter application-stage version. And treat connectivity as a measurable part of the case, not a general claim, so that a site can be shown to perform rather than simply asserted to.
Evidence expectations have risen
A faster, more standardised process does not mean a lighter one. If anything, the evidence bar at plan stage is higher, because allocations are being made with less room for argument later. Transport evidence that would once have been developed at application now needs to be ready earlier and to a firmer standard. That is a cost, but it is also an opportunity. A site that arrives with strong, consistent evidence is easier for an authority to allocate and harder for objectors to pick apart, which is exactly the position a promoter wants to be in.
Timing is the thing to watch
The move to the new system does not happen everywhere at once. Different authorities sit at different stages, and a plan already well advanced under the old rules follows a different path from one starting fresh. For a site promoter, the first job is to work out which regime the relevant plan sits under, and what that means for the evidence expected and the window to influence it. Getting this wrong can cost months. Getting it right lets you prepare the right case at the right moment, rather than reacting once decisions have already firmed up.
The bigger shift
The new plan-making system is part of a wider effort to speed up how development is delivered, and it rewards preparation. Sites that come forward with strong, consistent evidence, aligned to national policy, will move more smoothly through it. That is as true for transport as for any other topic, and it is why the work TPA does on major developments increasingly starts at plan stage rather than at application.
If you are promoting a site through a local plan and want the transport case to carry weight, TPA can help. You can get in touch with TPA’s team via the London office, the Bristol office, or the Cambridge office to talk it through.
