We have seen many projects across the UK struggle to deliver after consent and planning have been approved.
Ahead of UKREiiiF 2026, we have produced several thought leadership articles focused on the current delivery gap in the UK.
Read The Delivery Gap: You Don‘t Have a Site Without a Connection below.
For decades, the industry has operated under a simple mantra: “Secure the planning consent, and the project is a go.” This milestone has historically dictated investment cycles, project timelines, and commercial valuations. But in today’s infrastructure-constrained environment, that logic is fundamentally broken.
In this critical analysis, Shayan Ghaderi highlights a growing crisis across the UK: the “Delivery Gap” caused by a gridlocked utility network. With a national connection queue that has spiralled to over 700GW, securing a “consented” site is no longer the finishing line, it is often where the real battle for viability begins. If a project can’t connect to power, water, or digital infrastructure on the right timeline, it isn’t a deliverable site; it’s a commercial liability.
Planning permission has long been treated as the decisive milestone in development. Secure consent, and the scheme moves forward. That logic shaped investment decisions, programme assumptions and delivery strategies for years.
It no longer holds.
Across the market, schemes are progressing through planning only to hit a harder reality later: they cannot connect on the timescale the project needs. In some cases, that means redesign. In others, it means delay, additional cost or a consented site that remains undeliverable.
This is the delivery gap. And it is widening.
For years, utilities sat in the background of development strategy. They were technical, complex and important, but rarely seen as the factor that determined whether a project could proceed at all.
That is no longer the market we are operating in.
Electricity capacity, connection dates and wider infrastructure availability have moved to the front of the programme. NESO has highlighted that the legacy grid queue had grown to more than 700GW, around four times what is needed by 2030, while government and Ofgem have both acknowledged that long waits for connections are now a barrier to investment and economic growth.
Recent reforms are substantial, but they are also a signal of how serious the problem has become, not evidence that it has disappeared.
At the same time, pressure on the system continues to rise. Clean Power 2030 depends on accelerating new energy infrastructure, while demand from logistics, housing, electrified transport and data centres continues to intensify. The government’s consultation on prioritising connections for “strategic demand” reflects the growing gap between viable projects and available capacity.
That matters far beyond the energy sector. It changes the fundamentals of site viability.
When utilities are constrained, the impact is felt in commercial performance before it is felt in technical design.
Build-out programmes slip. Capital is held for longer than expected. Procurement decisions need revisiting. Phasing assumptions unravel. A scheme that looked straightforward at the planning stage becomes operationally uncertain once infrastructure realities catch up with it.
That is why “consented but stalled” is becoming more common. The risk is not simply that projects take longer. The deeper risk is that connection is still treated as a downstream issue when it is now one of the clearest determinants of whether value can be realised at all.
Market analysis reinforces this. Demand for new electricity connections is outpacing the network’s ability to expand capacity, with available headroom increasing only modestly as connection demand rises sharply. The pressure is structural, not anecdotal.
The issue is not that utilities are difficult. It is that they are still too often considered too late.
There are three recurring points of failure.
The first is timing. The utilities strategy is often developed after key decisions on site layout, density, use mix, or phasing have already been taken. By that stage, the project is already carrying assumptions that may not align with available capacity or realistic connection dates.
The second is visibility. Connection risk is not always well understood early enough. Teams can be working from outline assumptions rather than a credible picture of infrastructure constraints, lead times or reinforcement requirements. That creates false confidence in the programme and viability.
The third is misalignment. Planning, design, and investment decisions can move forward on one set of expectations while infrastructure delivery operates on another. The result is a scheme that is approved on paper but disconnected from what is deliverable in practice.
This is where value starts to leak out of projects, not in one dramatic failure, but through avoidable friction, redesign and delay.
There is a temptation to assume the answer lies in national reform alone. Reform matters, and the current changes are significant.
Ofgem’s queue reforms move away from a first-come, first-served model towards prioritising projects that are both needed and ready. At the same time, projects that are no longer progressing or required are being removed from the system, alongside wider changes to planning and infrastructure frameworks.
These are important shifts. But they do not create universal certainty for every site. They create a more strategic system, which means developers and investors must become more strategic, too.
The question is no longer whether capacity exists somewhere in the system. It is whether a project can secure the right connection, in the right place, on the right timeline, with a business case that still stands up once infrastructure constraints are properly understood and priced in.
That is a different proposition entirely.
The most effective projects now treat utilities as a core driver of early strategy.
They do not wait for planning to expose the issue. They use an understanding of infrastructure to shape the scheme from the outset.
That tends to show up in three ways.
First, the infrastructure strategy is developed early. Capacity, connection options, likely reinforcement needs and phasing implications are considered before the scheme hardens around assumptions that may later prove unrealistic.
Second, risk is identified before it becomes critical. Where constraints are understood early, teams can adapt. They can revisit density, re-sequence phases, test alternative energy strategies or reconsider timing before cost and complexity escalate.
Third, delivery is aligned with infrastructure reality. The strongest schemes are not simply ambitious; they are calibrated. Planning, design and investment decisions reflect what can actually be delivered, rather than what the programme originally assumed.
That is increasingly the dividing line between schemes that progress and schemes that drift.
Utilities should no longer be seen as a constraint to manage at the end. They are now among the systems that define what is possible at the outset.
That challenges one of development’s most persistent assumptions: that once consent is secured, delivery is mainly a matter of execution.
Today, consent without connection is not certainty. It is exposure.
The more useful question is no longer, “Can we get this approved?” It is, “Can we get this delivered on terms that still make commercial sense?”
That is where viability now lives.
For developers, landowners, investors and project teams, the implications are clear.
Utilities need to be tested earlier. Capacity and constraints need to be understood before commitments are locked in. Design and phasing need to reflect the reality of the infrastructure. Delivery strategies need to be built around credible connection pathways, not inherited assumptions.
Because the market has changed.
Planning permission still matters. But it is no longer the final proof that a site is ready to move.
If a scheme cannot connect, it cannot deliver.
And if it cannot deliver, it is not a site at all.
