UK house prices flatlined or dropped slightly in September, while fixed mortgage costs surged back to three-year highs. High borrowing costs and economic anxiety ahead of the upcoming Autumn Budget have driven buyer caution, wiping out the temporary momentum seen earlier in the summer. The latest data from major lenders highlights a stark cooling of the property market:
- Lloyds HPI (Halifax Tracker): Reported that average house prices were entirely flat (0.0%) on both a monthly and annual basis in September, leaving the typical home valued at £298,441.
- Nationwide Index: Indicated an actual monthly decline of 0.2%. Annual house price growth plummeted from 1.6% in August to 0.8% in September, marking the weakest rate of annual expansion since December 2025.
- A Two-Tier Market: Detached and terraced properties continue to see some resilience, but flats are bearing the brunt of the downturn, actively losing value year-on-year due to mounting leasehold compliance issues and buyer preference for freehold space.
- Regional Divide: Northern Ireland continues to outperform the rest of the UK with annual growth hitting 7.4%. Conversely, Greater London (-2.2%) and the South East (-2.1%) saw the most severe contractions.
Although the Bank of England held the base interest rate at 3.75% on 17 September, fixed mortgage products have become substantially more expensive:
- Sub-5% Deals Extinguished: The availability of fixed homeowner mortgage deals priced below 5% has been virtually wiped out. Moneyfacts reported that the number of sub-5% fixed-rate choices plummeted from 1,494 at the start of September to just nine.
- Rates Approaching 6%: Driven by rising inflation concerns and scaling gilt yields (partly aggravated by energy inflation from Middle East tensions), lenders have aggressively repriced. By early October, the average five-year fixed rate hit 6.00% for the first time in three years, and the average two-year fix climbed to 5.98%.
- Impact on Demand: As a result of these spiked costs, mortgage applications for home purchases dropped significantly (down over 18% in Q3 year-on-year), leaving would-be buyers waiting to see what support might arise in the 28 October Budget.
