Why London Can’t Deliver the Homes It Desperately Needs, And How We Fix It
- Feb 11

London stands at a crossroads. For years, we have watched the gap between housing need and housing delivery widen into something unmanageable, edging ever closer to a full‑blown crisis. What was once a concern debated in policy circles has now become an unavoidable reality shaping the lives of millions. The capital is producing nowhere near the number of homes required to meet its population’s needs, and this shortfall carries profound economic, social and human consequences.
The crisis is not abstract. It manifests in rising homelessness, spiralling rents, overcrowded homes, and an exodus of key workers who can no longer afford to live in the city they serve. Young families unable to secure stability, older residents unable to downsize, and employers unable to recruit, all feel the strain of a system that has failed to keep pace with demand. London’s competitive edge, once taken for granted, is under pressure as both talent and investment look elsewhere.
At the heart of the issue lies a painful truth: our housing system has become paralysed by political hesitation, process-heavy decision‑making, and a misalignment of incentives. Housing delivery is treated as a political battleground rather than a shared national priority. We have allowed competing agendas, regulatory over‑engineering and fragmented governance to create a labyrinth in which good schemes falter, innovation is stifled, and momentum is lost.
This is why I argue that the delivery of homes in London must now move beyond politics. Housing is not a partisan issue. It is infrastructure, as essential as railways, hospitals or energy networks. It is the foundation on which a healthy, productive and cohesive society is built. Without addressing the housing shortage at scale and with urgency, London cannot remain a global city that people from every background can afford to call home.
Yet, despite the bleak headlines, the situation is far from hopeless. There are clear, practical steps we can take to reignite delivery. We can simplify the planning system, reduce unnecessary cost and delay, empower smaller developers, and encourage collaboration across sectors. London has the talent, the land opportunities, and the expertise required to build, but only if we create the conditions that allow the industry to function.
This blog explores the root causes of London’s housing paralysis and offers a set of grounded, actionable solutions. My aim is not simply to diagnose the problem, but to outline a path forward, one that restores confidence, unlocks capacity, and re‑establishes our collective ability to build the homes Londoners deserve.
Context: A System Under Strain
The evidence paints a stark and increasingly alarming picture of London’s capacity to deliver new homes. Despite sustained demand and political acknowledgement of the crisis, the capital’s housing output continues to lag dramatically behind what is required. Net housing supply in London reached 37,582 homes in 2021/22, a figure that falls well short of both the London Plan target of over 52,000 homes per year and the Government’s more ambitious, and increasingly urgent, revised target of 80,000 homes annually. This persistent under‑delivery is not a marginal gap; it represents a systemic failure to keep pace with population growth, household formation and economic demand.
Yet the most serious warning signs come from the collapse in housing starts, the pipeline of future supply. Research from Molior shows that in Q3 2025 fewer than 1,000 homes actually began construction, placing London on track for a catastrophic total of just 5,000 new starts for the entire year, a mere 5.7% of the 88,000 homes London should be delivering to remain on a sustainable trajectory. Even more concerning is the unevenness of delivery across the capital: twenty‑three of London’s thirty‑three boroughs recorded zero new housing starts in Q1 2025, highlighting a system that is not simply under‑performing but actively stalling. Such widespread inactivity suggests deep structural issues in planning capacity, viability, land availability and developer confidence.
These acute pressures are compounded by a dramatic downturn in planning approvals across England. Planning consents, a critical leading indicator of future delivery, have fallen to a 14‑year low, with just 7,344 approvals granted in the most recent quarter. This figure represents a 40% decline from the 2016 peak, signalling a planning system that is slowing down precisely when it needs to accelerate. For London, where build costs, land constraints and regulatory complexity are already more severe than in other regions, this drop in approvals represents a profound threat to future supply.
Taken together, these indicators reveal a housing system under strain at every point: from the initiation of projects, to the granting of permissions, to the actual delivery of completed homes. The message could not be clearer: London is simply not building homes at anything close to the pace required to sustain a thriving, equitable and economically resilient city. Unless the city can unblock this pipeline and restore confidence in both planning and delivery, the housing crisis will deepen, with repercussions felt across every community, every sector and every generation.
1. Housing Delivery: When Regulation Becomes Paralysis
There is no escaping the fact that London’s planning system has become too slow, too complex, and too adversarial to support the scale of delivery the capital urgently needs. For years, developers, local authorities and housing associations have warned that the system is grinding to a halt, but the latest data makes clear that this is no longer a warning; it is a reality. Only 20% of major planning applications in England were decided within the statutory 13‑week timeframe in the year to March 2025, a figure that exposes a system buckling under its own weight. Some councils did not determine a single major application within the required period, demonstrating the depth of capacity shortages and administrative overload. Developers now speak not in terms of months but in years when estimating how long it will take to move even modest applications through the planning process.
Much of this delay stems from good intentions that have accumulated into counterproductive burdens. Biodiversity requirements, heritage protections, design codes, environmental assessments and transport obligations are individually sensible, yet together, they form a dense layer of regulatory expectations that many planning teams simply do not have the bandwidth to process. Instead of delivering clarity and quality, the system is often characterised by uncertainty, contradictory expectations, and a fear of challenge, all of which stall progress rather than support it.
This regulatory drag is now visible not just in applications but in outcomes. Molior’s analysis shows that completions, the homes that actually get built, are falling sharply. London produced just 28,576 completions in 2024/25, far below what is required to maintain even the current inadequate supply level, with forecasts suggesting further reductions ahead. A system that cannot approve projects efficiently will, inevitably, struggle to deliver them.
And then there are the absurdities, the stories so counterintuitive they have become shorthand for the dysfunction of the system: the Portakabin that requires a bat survey, the minor design amendment that triggers a full viability reassessment, or the single line of elevation detail that forces an applicant back through multiple rounds of consultation. These may seem trivial, but they reflect a wider issue, a system structured in such a way that it is easier to delay than to decide, easier to object than to approve, and far easier to halt a scheme than to bring one forward.
If London is to return to anything resembling a functional delivery environment, it needs more than incremental reform. It needs a sustained period of deregulation, a willingness to simplify rather than add, and a cross‑party commitment to treating housing as essential infrastructure rather than a political battleground. The objective must be to create a system in which well‑designed, well‑located schemes can move swiftly, predictably and efficiently through planning, freeing both public and private sectors to focus on delivery at scale.
In short: to get London building again, we must first get London planning again, decisively, consistently and with the urgency this moment demands.
2. Service Charges: An Overlooked Barrier to Affordability
While much of the housing debate focuses on planning, land supply and developer capacity, service charges represent a quieter but increasingly significant threat to affordability, particularly for renters, leaseholders and older residents. These costs, once a relatively predictable component of housing expenditure, have escalated so sharply that they now risk undermining the very purpose of new housing delivery: to provide secure, sustainable and affordable homes.
Over the past five years, service charges have risen at a rate far outstripping inflation. According to The Property Institute’s Service Charge Index, the average service charge has increased by 41% since 2019, rising from £2,523 to £3,634 per leaseholder across a sample of more than 13,000 homes. Even within a single year, the pressure has intensified: data shows that 2024 alone saw an 11% rise in service charges, with average charges across England and Wales reaching £2,300 annually. These increases now mean that, for many households, the service charge is their largest cost after the mortgage or rent, a complete inversion of how the tenure system was originally designed to function.
The trend is even more stark in the retirement sector. Reporting by national outlets highlights that service charge expectations of £5–6 per square foot, roughly £5,000 per unit per year, are placing severe financial strain on retirees living on fixed incomes. This is particularly worrying given demographic trends: as London’s population ages, and as more older residents seek accessible, supported living environments, escalating service charges risk pricing people out of precisely the types of housing designed to meet their needs. For many pensioners, service charges now rise faster than their pension uprates, eroding financial security year after year.
Understanding the drivers of these rising costs is essential:
Policy‑driven building complexity: Requirements for intricate façades, multi‑material constructions, and compliance‑heavy design standards result in buildings that are more expensive to maintain over their lifetimes.
Higher mechanical and electrical (M&E) expectations: Modern developments often feature extensive M&E systems, air‑handling units, high‑spec lifts, concierge systems, complex fire safety installations, which are costly both to operate and to service.
Insurance and energy spikes: Buildings insurance premiums have risen dramatically in recent years, particularly in blocks with cladding or structural risk profiles. Energy costs, still volatile, feed directly into service charge budgets for communal heating, lighting, and plant operations.
New building safety regulatory requirements: Post‑Grenfell compliance standards, while essential for resident safety, add a significant financial burden. Professional fees, inspections, reporting obligations and compliance works all translate directly into higher service charges.
These costs are not absorbed by the public sector or by developers; they fall squarely on the resident, whether they are a social tenant, private renter, shared owner or leaseholder. The result is a landscape where new homes may meet planning ambitions on paper, but in practice become economically inaccessible due to the sheer scale of ongoing operational costs.
If London is serious about long‑term affordability, the focus cannot remain solely on the cost of building homes. We must address the cost of running them. That means adopting policies that reduce rather than increase long‑term liabilities: encouraging simpler, more efficient building forms; revisiting design standards that add cost without delivering commensurate value; and ensuring regulatory requirements are proportionate and predictable.
True affordability extends far beyond the purchase price or rent level. It is about ensuring that homes remain financially sustainable to live in across decades. Until policy makers, planners and designers integrate service charge implications into their decision making, London will continue to produce homes that are “affordable” in name only, and unaffordable in reality.
3. Market Operators: Declining Diversity, Rising Barriers
London’s development landscape has changed dramatically over the past decade. Once characterised by a healthy mix of major developers, regional builders, housing associations, and a vibrant SME (small and medium‑sized enterprise) sector, the market has consolidated to a worrying degree. Today, a shrinking number of large operators hold an increasingly dominant share of the pipeline, while the SME sector, historically essential for tackling smaller, trickier urban sites, finds itself pushed to the margins.
This contraction matters. Smaller builders were once the lifeblood of London’s delivery ecosystem, able to take on infill plots, awkward brownfield parcels and community‑scale projects that larger players often overlook. But as recent research from the London School of Economics and the Federation of Master Builders highlights, SMEs now face a constellation of barriers that severely limits their ability to enter, compete, or scale within the capital:
Persistent planning delay and complexity, which disproportionately impacts SMEs lacking large in‑house planning teams
High land and planning costs, with upfront expenditure often running into hundreds of thousands of pounds before a single brick is laid
Limited access to affordable finance, constraining cashflow and inhibiting pipeline growth
Rising labour and material costs, which erode already‑tight margins [lse.ac.uk], [fmb.org.uk]
The Home Builders Federation’s State of Play report provides a stark illustration of these hurdles. It found that 51% of SME builders now wait more than a year for planning permission, while only 1% secure approval within three months, a timeline once considered normal for smaller applications. At the same time, planning‑related costs have surged by 30% over the past three years, driven by increased regulatory requirements, consultant fees and the costs of navigating prolonged decision periods. These delays and escalating costs are not abstract burdens; they directly impair SMEs’ ability to operate, often rendering otherwise viable schemes financially unworkable.
But perhaps the most structural barrier facing SMEs is the collapse of traditional financing routes. When now‑major developers such as Berkeley, Barratt and Redrow were emerging, they relied heavily on high street bank lending to fund early‑stage development. Those days are gone. Mainstream lenders have retreated from SME residential development, deterred by regulatory capital requirements, perceived risk, and the elongated planning cycle that undermines loan predictability. In their place, SMEs are increasingly forced to turn to specialist lenders with higher interest rates, shorter terms and tighter conditions, dramatically inflating project risk.
This withdrawal of accessible, affordable finance is not merely a challenge, it is a structural choke point. It effectively slams the door shut on new entrants, preventing the next generation of local, dynamic developers from establishing themselves and contributing to London’s housing supply. Without SMEs, London loses:
Innovation, as smaller builders are often first to adopt new materials, designs and construction methods
Competition, which helps moderate pricing and increase choice across tenures and typologies
Delivery capacity, especially on small sites that collectively represent a significant quantum of potential homes
In short, a diverse development ecosystem is fundamental to a healthy housing market. A system dominated by only a handful of major players becomes less agile, less resilient and less capable of responding to local needs. If SMEs cannot re‑enter the London market, the capital risks further stagnation, with fewer homes delivered, slower regeneration, and a continued erosion of the city’s ability to build for its future.
4. Next Steps: Concrete Measures to Re‑ignite Supply
If London is to reverse the downward trajectory of housing delivery, the response must be structural, deliberate and sustained. We cannot tweak around the edges of a failing system. We must address the root causes of stagnation head‑on, finance, investment diversity, regulatory overload, and the cost of entry for new market participants. Below are the practical, targeted interventions that would meaningfully shift the dial.
A. Incentivise UK Banks to Lend Again
At the heart of London’s delivery slowdown is a chronic shortage of accessible finance, particularly for SMEs, the very organisations that once formed the backbone of housing delivery on small and medium‑sized sites. Where major developers can absorb multi‑year planning delays and rising borrowing costs, SMEs simply cannot. The government should introduce tax incentives, loan guarantees and risk‑sharing mechanisms that encourage mainstream banks to return to SME development lending. These tools were used effectively in the post‑2008 recovery period and can be redeployed to stimulate confidence and liquidity in the market. Such interventions would:
Reduce dependence on high‑cost specialist finance
Improve project viability
Support new entrants into the development ecosystem
Boost capacity on small sites that collectively could deliver thousands of homes
Without restoring a dependable banking relationship for SMEs, London’s housing sector will remain dangerously unbalanced.
B. Reduce Over‑reliance on Build‑to‑Rent (BTR) Private Equity
London has increasingly backed itself into a corner by leaning too heavily on BTR private equity as the primary vehicle for large‑scale delivery. And while BTR plays an important role in providing high‑quality rental stock, it cannot, and should not, be the only show in town.
As I often say: nobody walks into a casino and places every chip on red. Yet this is effectively what London has done, narrowing its funding universe to a single dominant capital source.
A healthier investment landscape would include:
More institutional long‑term capital (e.g., pension funds)
Revitalised bank lending
Government‑backed development finance
Mixed‑tenure models that better distribute risk
Incentives for UK‑based mid‑scale investors
Diversifying capital sources makes the system more resilient, supports a wider variety of schemes, and reduces exposure to cyclical shifts in global private equity appetite.
C. Simplify Policy & Reduce Cost of Entry
If the system remains too expensive, too unpredictable and too administratively heavy for developers to operate within, then no level of funding reform will matter. London must become a place where well‑designed, policy‑compliant schemes can progress without friction, particularly on the smaller and mid‑sized sites that SMEs depend on.
Key actions include:
Streamlining planning requirements, especially for small sites where complexity kills viability
Reducing viability assessment burdens, ensuring they are proportionate to scheme size
Relaxing unnecessarily prescriptive design codes that add cost without improving quality
Allowing simpler, lower‑cost building typologies, particularly mid‑rise walk‑ups and modular solutions
Curtailing excessive third‑party interventions, which can add months or years of delay
Recent government reforms, such as default approval for suitable sites, simplified biodiversity rules for smaller developments, and streamlined SME rules, are promising signals. But they remain insufficient on their own to reverse years of systemic inertia. London needs further, deeper reforms to fully modernise the planning and regulatory ecosystem.
Bringing It All Together
London cannot solve its housing crisis through a single lever. What is required is a coordinated and multi‑dimensional reset:
Finance must be cheaper and more accessible.
Investment must be diverse and not overly reliant on one model.
Planning must be faster, clearer and less adversarial.
Entry into the market must be achievable for SMEs, not reserved for large corporates.
Only by addressing all these areas together can London rebuild the diverse, competitive and dynamic developer ecosystem it once had, and, critically, deliver the homes its residents so urgently need.
5. Collaboration: London Builds Best When It Builds Together
Even amid London’s fragmented, overstretched and frequently adversarial housing landscape, there are projects that prove what is possible when the sector works in true partnership. One of the clearest examples is the long‑running regeneration of Woodberry Down in Hackney, a scheme that stands as a model for what collaboration, consistency and shared purpose can achieve.
Over a 20‑year regeneration programme, Woodberry Down is set to deliver more than 5,500 new homes, with at least 41% of these homes designated as social rent or shared ownership, ensuring long‑term affordability and mixed communities. This scale of delivery, backed by a commitment to social infrastructure, community facilities, public realm improvements and environmental enhancement, has been achieved through a partnership between Hackney Council, Berkeley Homes, Notting Hill Genesis, the Woodberry Down Community Organisation and the Manor House Development Trust.
What sets Woodberry Down apart is not simply the number of homes delivered, but the collaborative mindset that has underpinned every phase of the project. From the outset, the partners aligned around a shared ambition: creating a revitalised, mixed‑tenure community where existing residents were guaranteed high‑quality replacement homes and new investment flowed into schools, parks, youth centres, community spaces and transport links. This approach ensured that regeneration did not mean displacement, but renewal.
Woodberry Down demonstrates what becomes possible when:
Local authorities act as long‑term stewards rather than short‑term gatekeepers
Developers bring expertise, capital and delivery capability
Housing associations ensure affordability, management quality and social outcomes
Residents participate meaningfully, shaping priorities and ensuring accountability
Together, these actors created a coherent, long‑term partnership rather than the fragmented, scheme‑by‑scheme battles that characterise much of London’s planning landscape.
This kind of partnership approach fosters trust, something in short supply across London’s housing environment. It reduces friction, shortens negotiation cycles, stabilises viability, and sustains momentum even when markets fluctuate. Crucially, it anchors development in community benefit rather than transactional gain. As I often say, the bottom line is simple:
Help people into safe, affordable housing, of all tenures, so they can live well in the greatest city on earth.
Woodberry Down shows that this is not an abstract aspiration. It is entirely achievable when we bring together the interests of the public sector, private sector, civil society and local residents behind a single, shared purpose. London does not lack expertise, nor imagination, nor commitment. What it has lacked is alignment.
But where alignment exists, London builds, and it builds well.
Conclusion: A Call to Be Bold
London’s housing crisis is not an inevitability. It is the product of choices, structures and systems that can be changed, if the will exists to change them. The data throughout this analysis shows a system that is stuck, constrained by inertia, complexity and fragmentation, but crucially not beyond repair. London still has the talent, the land, the institutional capacity and the investment appetite to deliver the homes it needs. What it lacks is a coherent, decisive framework capable of unlocking that potential. To move forward, we must be honest about what is required. We must:
Depoliticise housing delivery, treating it as critical national infrastructure rather than a political battleground.
Simplify planning, creating clarity, predictability and proportionate expectations.
Reduce development costs, ensuring regulatory ambition does not outpace financial reality.
Re‑open finance to SMEs, rebuilding a diverse developer ecosystem that strengthens resilience and competition.
Adopt building typologies that lower long‑term service charges, protecting affordability not just at the point of purchase but across the lifespan of a home.
Encourage cross‑sector collaboration, recognising that London succeeds when local authorities, developers, housing associations and communities work as partners rather than adversaries.
Above all, we must recognise that housing is foundational infrastructure, every bit as essential as transport, energy, healthcare, education or digital connectivity. Without stable, affordable homes, none of the other systems London relies on can function effectively. Housing underpins economic growth, social cohesion, public health, workforce stability, community resilience and long‑term prosperity.
London can build again at scale. It can deliver the homes its people need, support thriving mixed communities, and retain its position as one of the world’s most dynamic and inclusive cities. But doing so requires a willingness to act decisively, to rethink outdated assumptions, and to push beyond the incrementalism that has characterised the last decade. The time for half‑measures has passed. The challenges are real, but so too are the opportunities. If we want a liveable, dynamic and equitable city, one worthy of London’s global stature, then we must act boldly.
And we must act now.
