Britain's new towns: a strategic refocus for housing delivery

As we prepare for the ICAEW event, "Getting Britain Building – can New Towns unlock Britain’s housing future?" on 28 April 2026, the conversation around new towns has taken a significant turn. While the New Towns Taskforce report in September 2025 initially identified 12 promising locations, recent developments suggest a strategic recalibration by the government. This isn't necessarily a scaling back, but rather a sharpening of focus to maximise the potential for success.

Britain faces a persistent housing crisis, characterised by unmet demand, affordability issues, and the struggle to create sustainable, thriving communities. Against a backdrop of constrained public finances, rising construction costs, and limited capacity within existing urban areas, the new towns model has re-emerged as a compelling solution. It offers the potential for large-scale, master-planned developments that integrate housing, employment, green spaces, and infrastructure from the outset, attracting long-term investment from institutional players.

The New Towns Taskforce was established to identify viable locations and principles for a new generation of such settlements. Their September 2025 report recommended 12 strategic locations across the UK, a mix of brand-new settlements, already promoted new towns, and sustainable urban extensions or city centre regenerations. These included ambitious projects like Adlington in Cheshire East, Marlcombe in East Devon, and Tempsford in Central Bedfordshire, designed to serve growing industries and maximise the benefits of infrastructure like East West Rail. Existing schemes, such as Heyford Park in Oxfordshire and Worcestershire Parkway, were also highlighted, alongside significant urban regeneration opportunities in Bristol (Brabazon), Enfield (Chase Park), Greenwich (Thamesmead), Leeds (South Bank), Manchester (Victoria North), Milton Keynes, and Plymouth.

However, the landscape is already evolving. In March 2026, it was revealed that the government is set to radically reshape its flagship programme. This involved deprioritising some existing projects or initially recommended sites that are now deemed unviable. The Ministry of Housing, Communities and Local Government whittled the 12 down to 7 locations and we wait for further updates. This dynamic approach underscores the complexity of such large-scale undertakings and the need for adaptability. The focus appears to be on ensuring that the chosen sites have the highest probability of delivering on the government's ambitious housing targets and creating genuinely sustainable communities.

The Taskforce's recommendations, and indeed the government's evolving strategy, highlight that success hinges on treating new towns not as short-term housing projects, but as long-term investment systems. This requires a fundamental shift in mindset and a collaborative effort across public and private sectors.

1. Development corporations as delivery vehicles: the Taskforce strongly advocated for the role of development corporations in almost every new town scheme. These bodies are crucial for providing stability, strategic oversight, and the necessary powers for planning, funding, land assembly, placemaking, and long-term stewardship. The government's interim response agrees with a "preference" for development corporations, recognising the need for flexibility in their structure – whether centrally-led, mayoral, or local – and the potential for public-private partnerships. The direction of travel is clear: we can expect to see more development corporations playing a pivotal role.
2. Funding and financial models: in a fiscally challenged environment, the emphasis is shifting from grant funding towards government loans, government-backed guarantees, and land partnerships or joint ventures. This ensures a return on public investment where appropriate. However, significant upfront funding will still be required, potentially backed by the Social and Affordable Homes Programme, the National Housing Delivery Fund, and the National Housing Bank. The Taskforce also recommended exploring tax financing instruments, similar to Crossrail's model, and ensuring other government departments factor new town needs into their spending plans.
3. Land assembly and viability: effective land assembly and value capture mechanisms are critical. The Taskforce encouraged the use of Compulsory Purchase Order (CPO) powers, "no scheme" valuations, and the disapplication of hope value to facilitate land acquisition. The government is reviewing planning practice guidance on viability to ensure landowners receive a fair return while minimising development costs, thereby supporting high placemaking standards.
4. Public-Private Partnerships (PPPs): PPPs are actively encouraged, provided they align with new town principles. The success of these partnerships relies on clear propositions, masterplanning, planning certainty, and long-term stability to attract investor demand. Our event will hear from Mary Parsons of Lovell Partnerships, who will share her experience on the indispensable role of private partners in bringing capital, expertise, and efficiency to accelerate delivery.
5. Role of local authorities: while development corporations take the lead, local authorities with strong track records in housing delivery are expected to play an enhanced role. They are also crucial for ensuring local support and representation on governing bodies, fostering effective long-term stewardship.
6. Planning and regulatory reform: the Taskforce proposed a wide range of reforms, including an interim planning policy to protect new town locations, clear minimum density thresholds, and a minimum target of 40% affordable housing (with at least half for social rent). Fast-tracking statutory consultee processes, reviewing legislative frameworks, and reforming national infrastructure planning are also key. The government's interim response indicates a commitment to many of these, including establishing spatial planning frameworks and considering how best to support new towns within the National Planning Policy Framework (NPPF).
7. Stewardship, sustainability, and innovation: long-term stewardship models, clear environmental visions, and a focus on innovation are paramount. This includes promoting Modern Methods of Construction (MMC) to provide a stable pipeline for housebuilders, fostering innovation in construction, and ensuring new towns are designed with future digital needs in mind, potentially leveraging "digital twins" and community data stores. Oliver Steel from Mott MacDonald will elaborate on how strategic infrastructure investment is not just a cost, but a catalyst for growth and value creation.

The question, "can new towns unlock Britain’s housing future?" is complex, but the answer is a qualified "yes." However, this success hinges on a strategic, long-term approach that views new towns as integrated investment systems. The government's recent recalibration, while potentially deprioritising some initial sites, signals a commitment to focusing effort where success is most achievable. This requires robust delivery vehicles like development corporations, innovative funding models, effective land assembly, strong public-private partnerships, and a comprehensive approach to planning, sustainability, and long-term stewardship.

As we look forward to the insights from our panellists – it is clear that the path to unlocking Britain's housing future through new towns is one of strategic focus, collaboration, and unwavering commitment.
