As the spring selling season peaks, Hometrack says that the UK new build sector continues to navigate affordability constraints and difficult market conditions. Analysis of NHBC data shows that sales in 2025 stabilised at 0.63 sales per outlet per week (excluding London), and, while this marks an improvement from 2023-24, recovery remains highly fragmented.
The analysis has found that housebuilders are offsetting squeezed margins by targeting a ‘product vacuum’ for four-bedroom houses in specific regions, but that this reliance poses a dual risk.
Hometrack says that it entrenches a ‘missing mainstream’ in national housing delivery, and as this buyer pool inevitably shrinks, it risks leaving housebuilders with stock that does not match market requirements.
To understand what is driving these local strategies, Hometrack’s newly released New Build Sales Rates Report explores a structural reset in the market: where the unwinding of the pandemic ‘race for space’ has allowed affordable northern markets to overtake the South. The report also reveals how current conditions are putting housebuilder incentives and national policy goals fundamentally at odds. Moving beyond national averages, the analysis maps out the exact criteria shaping the market and highlights why mainstream housing is being left behind.
A clear formula for sales resilience
The top-performing postcode areas in 2025 were defined by a careful balance of three criteria:
● Inventory discipline: Sales velocity relies on tight local supply. High-performing regions like the North East (0.66) and Scotland (0.68) are supported by a market where supply has contracted by 2% annually, according to Zoopla listings data. Conversely, southern markets have stalled (0.59-0.61) as developers battle a 10% to 12% surge in resale stock.
● Aspirational positioning: Targeting more affluent buyers is currently the most effective approach. Regions where four-bedroom houses make up over 42% of the new-build sales mix are outperforming with sales rates above 0.65. In these areas, new homes are some of the most expensive in markets with older and smaller stock, but are at more compelling price points versus resale equivalents of the same type and size.
● Attainable entry points: High-performing northern markets benefit from a much deeper pool of qualified buyers. Average new build prices in the North East and Scotland (£290,000–£340,000) are attainable for 22% to 25% of the local population (CACI paycheck data), assuming a 20% deposit and a 4.5 loan-to-income ratio. Highlighting the shrinking buyer pool, only 11% of local buyers can afford average new builds in the more expensive South East and East of England.
Ross Allan, managing director of data services at Hometrack, commented: “Housebuilders currently face tight margins in site selection and product mix. Developers must start looking beyond national averages and identify hyper-local pockets of opportunity, ensuring their existing product mix aligns closely with evolving localised demand.”
Overcoming the ‘missing mainstream’
The report concludes that today’s market ‘rewards selective precision over mass-market delivery’. While focusing on wealthier buyers offers a short-term fix, Hometrack warns that this small pool of demand will eventually dry up, leaving developers with a potential oversaturation of large homes. To stay resilient, builders need to watch local trends closely.
For the government, the data highlights a major challenge. To address this mismatch, the analysis suggests policymakers may need to explore options such as buyer support, targeted subsidies or reduced regulatory compliance costs to make mainstream housebuilding viable again. Ultimately, aligning developer incentives with policy aims will be key to achieving the scale of new home delivery the country needs.
