London Flats See High Proportion Sold at a Loss Over Five to Ten Years

London Flats See High Proportion Sold at a Loss Over Five to Ten Years

Nearly 40% of London flats resold within five to ten years have been sold at a loss, according to e.surv Chartered Surveyors. This trend is more pronounced in London than in other UK regions, reflecting ongoing challenges in the flat market.

New analysis from e.surv Chartered Surveyors reveals that during the 12 months to August 2026, almost four in ten flats in London that were resold after being held between five and ten years changed hands for less than their previous recorded purchase price. London recorded the highest proportion of such losses in Britain, with around one-third of flats in the South East and East of England also selling below previous purchase prices. The Midlands and northern England saw closer to one in five flats sold at a loss, while Scotland experienced fewer than one in ten flats sold below prior prices in the same holding period.

This data highlights a significant divergence in the performance of flats compared to houses, particularly since around 2017 when concerns over building safety, cladding, and service charges began to heavily influence buyer and lender decisions. The e.surv House Price Index shows that flats and houses have been moving apart in value since then, with flats underperforming in many regions.

Repeat-Sales Analysis and Regional Variations in Flat Market Performance

The repeat-sales method used by e.surv compares the price of properties sold more than once, providing insight into how values have changed for the same asset over time. The findings show a stark contrast between London and Scotland, where the flat market remains more stable. In Scotland, the price gap between flats and houses is narrower, and fewer flats are sold at a loss after five to ten years of ownership.

In London, the high proportion of flats selling at a loss reflects ongoing market pressures. These include the impact of building safety issues, such as cladding concerns, which have affected buyer confidence and financing availability. Service charges and tenure complexities also weigh heavily on flat values, making them less attractive relative to houses.

The overall housing market in Britain saw a modest 1.5% rise in average house prices over the year to September 2026, reaching £328,900. However, this growth has slowed, with prices falling slightly in the recent quarter and month. London remains the only region with a year-on-year price decline, down 2.3%, while Scotland leads growth at 3.5%, followed closely by Yorkshire and Wales at 3.4% each.

Implications for Landlords and Letting Agents in the Flat Sector

For landlords and letting agents, these trends underline the risks associated with investing in flats, especially in London and the South East. The likelihood of selling at a loss after medium-term ownership is higher for flats than for houses. This may affect portfolio strategies, particularly for those relying on capital growth or planning to sell within a decade.

The influence of building safety and service charge issues means landlords must be vigilant in managing these risks. Ensuring compliance with safety regulations and maintaining transparent communication about service charges can help sustain tenant confidence and property values. Letting agents should advise landlords on these factors when acquiring or managing flats.

Additionally, the divergence between flats and houses suggests that diversification within portfolios could mitigate exposure to flat market weaknesses. Landlords might consider balancing holdings with houses or properties in regions showing more stable or growing values, such as Scotland or Yorkshire.

What Remains Uncertain and Areas to Monitor

While the data clearly shows a trend of flats selling at a loss in certain regions, the underlying causes are multifaceted and evolving. The long-term impact of building safety reforms, changes in service charge regulation, and government housing policies remain uncertain. The upcoming Autumn Budget, which will include details on the Your First Home equity-loan scheme, may influence market dynamics further.

Landlords and agents should also watch for any shifts in mortgage lending criteria for flats, as lenders’ risk assessments continue to respond to building safety and tenure issues. The pace of regulatory change and enforcement could alter the attractiveness and value of flats in different areas.

Considerations for Landlords in Light of the Flats Market Challenges

• Review the condition and safety compliance of flat properties regularly to avoid surprises that could affect value or tenant retention.
• Monitor service charge levels and transparency, as these can impact both tenant satisfaction and resale prospects.
• Assess portfolio exposure to flats, particularly in London and the South East, and consider diversification to reduce risk.
• Stay informed about government policy changes, including housing schemes and building safety regulations, which may affect flat values.
• When planning disposals, factor in the potential for selling at a loss and evaluate timing carefully.
