Only 54,900 mortgages were approved for house purchase in August 2026, the lowest figure since December 2023. That single Bank of England number, paired with fresh data from Landmark Information Group, paints a picture of a property market holding its breath. The Landmark Q3 2026 property trends mortgage valuations down story is not just a statistic for economists to debate. It is a warning sign for anyone buying, selling, or remortgaging a home in England and Wales right now.
Landmark's Residential Property Trends Report, published 15 October 2026 and reported by The Intermediary, confirms what many estate agents and conveyancers have felt for months: transactions are slowing, valuations are falling behind last year's pace, and buyers are hesitating until they know what the Autumn Budget will bring.
Key Takeaways
- Mortgage valuations were 7% lower year-on-year in August 2026 and 2% lower in September, according to Landmark's Q3 2026 report.
- Agreed sales (sold subject to contract) averaged 11% lower than a year earlier, while completions fell 7%.
- Bank of England data show mortgage approvals dropped to 54,900 in August, the weakest reading since December 2023.
- Rising mortgage rates and Budget uncertainty are the two biggest drags on buyer confidence.
- Independent valuations and Level 3 surveys are becoming essential tools to avoid down-valuation shocks in a cautious lending market.
Inside the Landmark Q3 2026 Report
Landmark's quarterly report tracks the full conveyancing pipeline, from property listings through to completion. The Q3 2026 figures show a market that is cooling at almost every stage.
| Metric | Year-on-Year Change |
|---|---|
| Property listings | 2% lower (September matched 2025) |
| Agreed sales (sold STC) | 11% lower |
| Mortgage valuations (August) | 7% lower |
| Mortgage valuations (September) | 2% lower |
| Conveyancer search orders | 12% lower |
| Completed transactions | 7% lower |
Scotland's figures echo this pattern, with listings and sold-subject-to-missives both down 8% year-on-year.
Simon Brown, chief executive of Landmark Information Group, summed up the mood plainly: "The market remains subdued, and there is little in this quarter's data to suggest that will change in the near term." He pointed to borrowing costs, global uncertainty, and speculation about property tax changes ahead of the Autumn Budget as the key drags on moving decisions.
Why Agreed Sales Are Falling Faster Than Listings
The gap between a 2% drop in listings and an 11% drop in agreed sales is the most telling part of the Landmark Q3 2026 property trends mortgage valuations down story. Homes are coming to market at close to last year's rate, but far fewer buyers are committing to offers.
Elizabeth Jarvis, Landmark's divisional director of legal and search, put it bluntly: "Market conditions are giving little incentive for buyers to commit to a transaction."
This hesitation lines up with separate Zoopla data showing agreed sales down 9% in the four weeks to 20 September, with declines recorded in every region of the country. Buyers appear to be waiting, for clarity on the Budget, for rates to settle, or simply for more certainty before signing anything.
The Mortgage Rate Squeeze Behind the Numbers
Money is simply more expensive than it was at the start of the year. The average five-year fix at 75% loan-to-value stood at 5.2% at the end of September, up from 4% in January, adding roughly £150 a month to repayments on a typical loan. With the base rate at 3.75% and the next Bank of England decision due 5 November, affordability pressure is not going away soon.
Mike Holden, Landmark's divisional director of growth, offered an important caution against misreading short-term lending spikes: "When lenders raise rates, brokers move quickly to secure existing offers for their clients." In other words, a temporary jump in valuation or approval activity does not automatically signal recovery, it may just reflect brokers racing to lock in rates before they rise further.
Completions, Searches, and the Hidden Workload
Completed transactions fell 7% year-on-year, consistent with HMRC's provisional figures showing 96,250 residential completions in August 2026, down 9% on the previous year. Conveyancer search orders dropped even more steeply, down 12%.
Rob Gurney, managing director of Ochresoft, flagged a point easily missed in headline numbers: "Fewer cases do not necessarily mean a lighter workload for conveyancers." Longer, more complicated transactions, often stalled by valuation queries or chain delays, can consume just as much time as a higher volume of straightforward ones.
Ben Robinson, managing director of Landmark Estate Agency Services, noted that September's modest uplift may reflect delayed decisions finally working through the system, with ex-rental properties acting as a key driver of continued stock availability.
What Falling Valuations Mean for Buyers and Sellers
When mortgage valuations drop in volume, as the Landmark Q3 2026 property trends mortgage valuations down data shows, lenders typically become more cautious with the valuations they do carry out. Fewer comparable sales, longer timeframes between agreement and completion, and a jittery market all raise the risk of a lender valuing a property below the agreed purchase price.
A down-valuation can:
- Force buyers to find extra cash or renegotiate the price
- Delay or collapse a chain entirely
- Leave sellers accepting a lower figure than expected
"Market conditions are giving little incentive for buyers to commit to a transaction.", Elizabeth Jarvis, Landmark Information Group
This is exactly where an independent RICS valuation or a Level 3 Building Survey adds real protection. Commissioning a pre-offer valuation gives buyers evidence-based confidence before they negotiate, rather than discovering a shortfall weeks later when a mortgage lender's valuer flags concerns. For sellers, having robust, independent valuation evidence on hand can help justify an asking price and speed up negotiations with cautious buyers.
Preparing for the Budget: Why Timing Matters
With the Autumn Budget set for 28 October 2026, speculation about property tax changes is already shaping buyer behaviour. Many purchasers are deliberately pausing decisions until the details are confirmed. This creates a narrow window where sound, independent valuation advice is more valuable than ever, helping buyers and sellers move with confidence rather than guesswork while mortgage approval numbers remain soft.
FAQ
What did Landmark's Q3 2026 report find?
Mortgage valuations were down 7% year-on-year in August and 2% in September. Agreed sales fell 11%, and completions dropped 7%, pointing to a subdued property market.
Why did mortgage approvals fall to 54,900?
Bank of England data show approvals hit 54,900 in August 2026, the lowest since December 2023, reflecting higher borrowing costs and cautious buyer sentiment.
How does the Budget affect property decisions now?
Speculation about property tax changes before the 28 October Budget is encouraging many buyers to delay moving decisions until the outcome is known.
What is a down-valuation and why is it more likely now?
A down-valuation happens when a lender's valuer assesses a property below the agreed price. Fewer transactions and cautious lending make this more common in slower markets.
Can an independent valuation help avoid a down-valuation?
Yes. A pre-offer RICS valuation or Level 3 survey provides independent evidence of a property's true value, helping buyers and sellers negotiate with confidence.
Conclusion
The Landmark Q3 2026 property trends mortgage valuations down figures confirm a market in a holding pattern: fewer valuations, fewer agreed sales, fewer completions, and buyers waiting for clarity before the Budget. Rather than reacting after a lender's valuation causes problems, buyers and sellers should act early. Commissioning an independent RICS valuation or Level 3 survey before making an offer provides the evidence needed to negotiate confidently, avoid costly surprises, and keep transactions moving in an otherwise cautious market.
