UK house prices flatlined in September, with the average cost of a home stuck at £298,441, according to the latest tracker from Lloyds, as rising mortgage costs and geopolitical uncertainty weighed on the market. Economists had forecast a modest monthly rise of 0.1% and an annual increase of 0.2%, but prices showed no movement from the previous month or from a year earlier.

The flat result follows a 0.3% fall in August, the first monthly decline in three years, as prospective buyers faced higher mortgage rates and stretched affordability. In recent weeks, most big banks and building societies have increased mortgage costs because of turmoil in global bond markets, even though the Bank of England base rate has not changed since December last year.

On Monday, the average cost of a five-year fixed-rate mortgage reached 6% for the first time in three years. The rise in mortgage rates is bad news for borrowers whose fixed-rate deals are ending, for prospective buyers hoping to take out a mortgage, and for sellers seeking top prices.

The housing market slowdown adds to the squeeze on consumers from higher energy bills, linked to the Iran war, and rising prices elsewhere that have raised concerns of a new cost of living crisis.

Andrew Asaam, mortgages director at Lloyds, said: "While the market overall has been fairly subdued, property prices have so far proved resilient during a period of higher mortgage rates, which has been driven by changing expectations around the future path of base rate." He added that new inquiries from prospective buyers are now at their highest since February, but that any movement in house prices was likely to remain modest.

Analysis

Why This Matters

  • UK house prices are a key indicator of economic health and household wealth. Flatlining after a long period of growth signals that higher borrowing costs are starting to bite.
  • Rising mortgage rates directly affect millions of homeowners coming off fixed-rate deals and prospective first-time buyers, worsening affordability.
  • The squeeze on consumers is broader: higher energy bills and rising prices elsewhere point to a potential new cost of living crisis, with the housing market as a leading edge.

Background

The UK housing market enjoyed strong price growth through much of the post-pandemic period, fuelled by low interest rates and pandemic-era savings. The Bank of England raised its base rate from near zero to over 5% between 2021 and 2023 to combat inflation but has held it steady since December 2025. However, global bond market turmoil has pushed up mortgage rates independently, making home loans more expensive and cooling demand.

Key Perspectives

Homebuyers and borrowers: Face higher mortgage costs and tougher affordability checks. Those with expiring fixed-rate deals face a sharp increase in monthly payments. First-time buyers find it harder to get on the property ladder. Mortgage lenders: Report subdued activity but note that buyer inquiries are picking up. Lloyds sees resilience in prices but expects only modest movement. Economists: Had predicted a small rise in September prices. The flat outcome, combined with the August fall, suggests the market has lost momentum. Further weakness may materialise if mortgage rates stay elevated.

What to Watch

  • The trajectory of five-year fixed mortgage rates: if they stay at or above 6%, demand will likely cool further.
  • Bank of England base rate decisions: any cut would relieve pressure on borrowers and potentially stabilise the market.
  • Energy bills and broader inflation data: further increases could deepen the cost of living crisis and reduce housing market activity.
