A tale of two markets

The UK property market in 2026 is characterised by stark regional divergence. While Northern Ireland posts the strongest annual price growth in the country at 6.3%, pushing average values to approximately £195,000 according to ONS data, the picture in southern England tells a different story entirely.

REalyse transaction data reveals the scale of the affordability gap. Average prices in London stand at £599,180, with the South East at £406,186 and the South West at £334,001. These figures represent price-to-income ratios of 13:1 in the capital, 7.9:1 in the South East, and 7.6:1 in the South West—levels that continue to lock out significant portions of the buyer pool.

Why Northern Ireland is outperforming

Northern Ireland's relative affordability is the primary driver of its price momentum. At £195,000, the average home costs roughly a third of a typical London property and just under half of a South East home. This value proposition has attracted both local first-time buyers and cross-border investors seeking stronger yields.

The province also benefits from a more balanced supply-demand dynamic. While England recorded over 587,000 transactions in the past twelve months according to REalyse data, Northern Ireland's smaller market means new supply has less diluting effect on prices. Planning data suggests residential pipeline activity remains measured, supporting rather than undermining existing values.

Wales and Scotland have also posted positive annual growth of 1.5% and 0.5% respectively, with average prices of £231,197 and £235,112. However, England's overall average of £339,084 masks significant intra-regional variation, with the national figure dragged down by a 4.7% year-on-year decline—largely attributable to softness in the premium southern markets.

Mortgage rates and the affordability squeeze

The Bank of England's base rate trajectory remains central to regional market dynamics. While rates have stabilised from their 2023-24 peaks, borrowing costs continue to exert downward pressure on purchasing power in high-value markets.

A buyer in London paying £653 per square foot faces a fundamentally different proposition to one in Northern Ireland, where comparable properties trade at a fraction of that level. The monthly mortgage burden on a £600,000 London flat versus a £195,000 Northern Irish home creates entirely different risk profiles—and entirely different buyer pools.

This dynamic explains why southern England's transaction volumes, while substantial in absolute terms, have not translated into price growth. REalyse data shows the South East recorded nearly 100,000 transactions over the past year, yet prices remain flat or declining in many areas as motivated sellers adjust to new market realities.

Investment implications

For property investors, the regional divergence creates clear strategic considerations. Northern Ireland and other devolved markets offer entry points with potential for continued capital appreciation, while southern England may present opportunities for those targeting distressed or motivated sellers.

Rental yields also favour the regions. REalyse analysis indicates that gross yields in many Northern Irish postcodes comfortably exceed those available in London, where high capital values compress returns despite strong rental demand.

Outlook: divergence set to continue

The fundamentals underpinning this two-speed market show little sign of reversing in the near term. Until southern England prices adjust meaningfully relative to incomes, or wage growth accelerates substantially, affordability constraints will continue to cap buyer activity in the most expensive markets.

Northern Ireland and the devolved nations, by contrast, retain capacity for price growth precisely because they start from a more accessible base. For investors, developers, and analysts, understanding these regional dynamics—and having access to granular, up-to-date market data—will be essential to identifying opportunity in an increasingly fragmented UK property landscape.
