The UK housing market is bracing for a summer of considerable political speculation as the new Prime Minister, Andy Burnham, begins to outline his vision. Following his initial speech last week, which presented an ambitious but largely undetailed plan for housing, the sector is now scrutinising potential reforms that could reshape the property landscape. Among the key ideas anticipated to drive debate are significant changes to capital gains tax, a potential replacement of both stamp duty and council tax with a land value tax, and the promise of the largest social housebuilding programme since the Second World War.
However, with no concrete policy proposals yet published, property professionals are left to assess what, if any, of these measures will ultimately be implemented. This uncertainty comes against the backdrop of Labour's previous commitment to deliver 1.5 million homes, a target that has yet to be met. The ambiguity leaves many in the industry waiting to see how the government's rhetoric translates into tangible policy, particularly as the new administration also faces a reported £4.7 billion shortfall in the Defence Investment Plan, highlighting difficult financial choices ahead.
The uncertainty is already impacting market activity. In Prime Central London (PCL), average prices experienced a 3.6% annual decline in June for the second consecutive month, according to Knight Frank data. The number of transactions in PCL during the year to June 2026 was 14% lower compared to the preceding 12 months. In contrast, the more domestically driven market of Prime Outer London showed greater resilience, with average prices falling a modest 0.4% in the year to June, placing them at the same level as June 2022. Transaction numbers in Prime Outer London were down 7% year-on-year, but the number of offers made actually increased by 5%.
Nationally, the wider housing market is also showing signs of strain. The number of UK mortgage approvals saw a significant drop of 14.8% to 56,205, marking one of the largest monthly declines since records began in 1993. This downturn, according to analysts, is more closely linked to the ongoing Middle East conflict and its associated impact on mortgage rates, rather than domestic political uncertainty alone. Transaction numbers also fell by 2% between April and May, according to HMRC data, indicating an absence of the typical seasonal spring rebound.
For first-time buyers, the current lending landscape remains challenging, with higher mortgage rates making affordability a significant hurdle. Existing homeowners may face uncertainty regarding potential tax reforms, particularly those with properties that could be subject to changes in capital gains tax or a new land value tax. Landlords, too, will be closely watching any proposals, given the potential impact on their investments. The prospect of greater devolved tax-raising powers could also lead to regional variations in property taxation across the UK, adding another layer of complexity for buyers and sellers alike.
