A turning point for UK housing supply

For years, Britain's planning system has been blamed for throttling housing supply. Councils overwhelmed with applications, byzantine approval processes, and mounting refusals left developers frustrated and homebuilders falling short of targets. Now, that narrative is shifting.

REalyse data tracking residential planning applications across the UK shows a striking transformation. Approval rates have more than doubled—from just 32.5% in Q2 2023 to 71.3% by Q2 2025. This isn't a statistical quirk. It reflects genuine policy momentum, with streamlined planning pathways, reformed local authority processes, and central government pressure to prioritise housing all converging at once.

The December 2025 planning reforms, which simplified consent procedures for brownfield sites and standardised decision timelines, appear to be delivering on their promise. Combined with Homes England's expanded funding commitments, the conditions for accelerating new-build deliveries are finally aligning.

The pipeline in numbers

The scale of the current planning pipeline is significant. REalyse data shows over 1 million residential units are currently tracked across planning applications nationwide, spanning private and social housing schemes.

Central London dominates the pipeline with approximately 150,000 units in various stages of the planning process, followed by Kent with around 47,000 units and Greater Manchester with just over 40,000. The Home Counties and major regional centres—Essex, Cambridgeshire, the West Midlands, Hertfordshire—each hold pipelines exceeding 30,000 units.

Crucially, the flow of new applications remains robust. Q4 2025 saw submissions covering over 220,000 units—the highest quarterly figure in the dataset—suggesting developer confidence is strengthening despite ongoing economic headwinds.

Regional disparities in approval rates

While the national picture is encouraging, regional variation persists. REalyse analysis shows average approval rates of around 67% across local authorities, but individual areas diverge sharply.

Scotland stands out positively. Strathclyde, encompassing Glasgow and surrounding areas, recorded an 82% approval rate—the highest of any major region. Lothian (Edinburgh) achieved over 71%, while Lincolnshire and Suffolk in England both exceeded 75%.

At the other end, some southern counties struggle. Surrey's approval rate sits at just 37%, with Bedfordshire at 39% and Berkshire at 42%. Essex, despite its large pipeline, approves fewer than half of determined applications. These patterns often reflect local political pressures, Green Belt constraints, and infrastructure concerns that planning reforms have yet to fully address.

For developers and investors, these disparities create both risk and opportunity. Areas with streamlined approval processes offer more predictable timelines, while constrained markets may see faster price appreciation once supply does materialise.

What the reforms mean in practice

The December 2025 changes built upon earlier interventions but introduced several practical improvements. Automatic approval provisions for certain brownfield applications, reduced consultation periods, and standardised environmental assessments have all shortened average decision times.

REalyse data shows the impact: refused applications have fallen from over 800 per quarter in late 2023 to under 400 by mid-2025. Meanwhile, approved applications have climbed—Q1 2025 recorded over 1,000 approvals, triple the rate seen two years earlier.

Homes England's role cannot be understated. Enhanced funding packages for affordable housing components are helping schemes clear viability hurdles that previously stalled projects post-approval. With the government's target of 1.5 million net additions by the end of the decade, these interventions are designed to convert pipeline units into actual completions.

Looking ahead

The data is clear: planning approvals are accelerating. Yet challenges remain. Units started on site—the true leading indicator of delivery—show more uneven progress, with quarterly figures fluctuating between 5,000 and 27,000 units depending on market conditions.

Labour and material costs, mortgage affordability, and buyer confidence all influence whether approved schemes actually break ground. The planning system is only one piece of the puzzle, albeit a critical one.

For property professionals tracking this space, REalyse's planning and development data offers granular visibility into where supply is emerging—and where bottlenecks persist. As the market digests these reforms, expect continued regional divergence, with well-located brownfield schemes in high-approval areas likely to outperform.

The 1.5 million target remains ambitious. But for the first time in years, the planning system appears to be part of the solution rather than the problem.
