The supply and demand issue in the UK property market has intensified over the past decade. Rising population, low construction rates and constrained land availability have combined to create acute shortages of homes. This imbalance drives up prices and rents, challenging affordability for buyers and tenants alike.

What Drives the Supply and Demand Issue?

The core factors behind the supply and demand issue in the UK property market include:

  • Population growth: The UK’s population has grown by over 5 million since 2000, increasing household formation.
  • Underbuilding: New housing completions have averaged around 180,000 homes per year—far below the 300,000 needed to keep pace with demand.
  • Planning constraints: Local planning delays, green belt protections and infrastructure shortages slow delivery.
  • Investor competition: Institutional and overseas investors acquiring stock for buy-to-let and private rented sector reduce availability for owner-occupiers.

Statistical Evidence of the Imbalance

According to ONS data, private housing completions in 2023 were 184,270 while household growth exceeded 230,000, exacerbating the supply and demand issue in the UK property market.

Impact on House Prices and Affordability

Low supply relative to strong demand pushes house prices higher. Nationwide, average prices rose 7.2% year-on-year to June 2025, according to ONS House Price Index. In London and the South East, annual growth exceeded 9%.

This growth far outstrips wage increases, which averaged 4.5% over the same period, leaving many first-time buyers priced out. The price-to-earnings ratio now stands at 8.7 nationwide, up from 6.3 in 2010.

Consequences for the Rental Market

The private rented sector also feels the strain. With fewer homes to buy, more households remain in renting. According to Zoopla’s rental market report, rental stock is down 17% versus 2018, while tenant registrations per branch are up 25%.

Average UK rents increased 8.9% year-on-year to June 2025, outpacing inflation and raising landlord yields, but exacerbating affordability issues for tenants.

Regional Variations

While the imbalance is nationwide, it is most acute in:

  • London: Limited brownfield sites and strong inward migration create extreme shortages.
  • South East: High land values restrict developer margins, reducing incentive to build.
  • Major regional cities: Manchester, Birmingham and Bristol see high demand due to job growth but struggle with legacy infrastructure.

Strategies to Address the Imbalance

Government and industry responses include:

  • Planning reform: Streamlining approvals and incentivising brownfield development.
  • Infrastructure investment: Unlocking new sites through transport and utilities upgrades.
  • Build-to-rent schemes: Encouraging institutional delivery of rental homes.
  • Modular construction: Improving build speed and cost efficiency.

Opportunities for Investors

For high-net-worth investors, the supply and demand issue in the UK property market can yield opportunities:

  • Capital growth: Properties in undersupplied locations often outperform on valuation.
  • Rental yields: Strong tenant competition supports higher rents and stable cash flow.
  • Regeneration zones: Targeting areas with planned infrastructure can capitalise on future supply relief.
  • Off-plan developments: Securing units early in supply-constrained markets can lock in value before completion.

Managing Risks

The same drivers that support growth can heighten risk. Investors should:

  • Conduct due diligence on location fundamentals and supply pipelines.
  • Analyse demand drivers such as employment, demographics and transport links.
  • Structure financing conservatively, accounting for potential void periods.
  • Consider professional management to optimise occupancy and maintenance.
