Off-Market Property in the UK: What the 2026 Data Actually Shows

Search interest in "off-market property" has grown fast, but most of what ranks for it is tutorial content: where to find a deal, how to write a letter, which agents to call. Almost none of it answers a simpler question first: how much of the UK market actually sells this way, and how has that changed. This page is the data answer. For the practical, step-by-step version, GalimAI already publishes a complete guide to finding off-market property in the UK. This page sits alongside it as the numbers behind the term.

What percentage of UK property sales are actually off-market?

The most reliable recent figure comes from TwentyEA, a property analytics firm that tracks agent instructions and sales across England and Wales. Its Property and Homemover Report, published in October 2025, found that 15.8% of residential property sales between 2022 and 2024 took place off-market, meaning the property was never listed on a portal, an agent's website, in a shop window, or sold at auction.

That is not a fixed rate. It moved every year TwentyEA measured it, and the direction matters as much as the average:

The sharp drop in 2024 lines up with a change in market conditions rather than a change in how off-market sales work. TwentyEA recorded a 10% rise in new instructions that year, alongside successive interest rate reductions, which gave sellers more reason to compete for buyers with a full marketing package rather than a quiet private sale. In a buyer's market, discretion costs a seller exposure they can no longer afford to skip.

The 1 million pound divide

Price point is the clearest split in the data. Below 1 million pounds, only 6.7% of properties change hands off-market. Above that threshold, the figure jumps to 20.1%, roughly three times higher.

Below 1 million pounds, sellers depend on maximum exposure to reach a large, price-sensitive buyer pool. Above it, discretion, limited viewings and a pre-qualified buyer often matter more than reach. Two different markets, sharing one label.

This is also why most published commentary on "off-market property" reads like it is only about country houses and Kensington flats. A lot of the content that currently ranks for these terms is written by prime buying agents, and it reflects that end of the market almost exclusively, with little to no hard data on the much larger volume of sub-1m off-market activity.

Off-market share is not a constant, it swings with supply

Longer-run data backs up the same pattern. Hamptons research from June 2022, during the post-pandemic stock shortage, found a record 37,000 homes changed hands off-market in a single quarter, the highest number since 2007. At that point roughly one in ten homes sold nationally went unmarketed, the highest share since 2015, driven to 23% of all London sales and 24% of prime country sales.

That figure moved because stock was scarce and buyers were competing hard enough to transact before a listing went live. TwentyEA's 2024 figure of 11.4% shows the same mechanism running in reverse: more stock, less competitive pressure, less reason to skip the open market. Off-market share is best read as a symptom of supply and demand, not a fixed feature of the UK property market.

Where the next wave of off-market stock is coming from

TwentyEA and Hamptons can only measure sales after they happen. GalimAI reads the signals that come before a sale, across probate, insolvency, tribunal penalties, late Companies House filings, over-leverage and EPC non-compliance, spanning more than 460,000 property-holding companies in England and Wales. None of the owners below have sold yet. They are the pipeline the published off-market percentages are drawn from a year or two before TwentyEA ever counts them.

• 382,664 owners nationally show falling net assets, declining cash, or newly negative equity, a financial-contraction signal that often precedes a sale (GalimAI data, as of July 2026).
• 58,110 owners nationally hold cash under 5,000 pounds with net assets below 10m pounds; 67% also carry a second distress signal (GalimAI data, as of July 2026).
• 16,503 tribunal cases are indexed across England and Wales, covering 3,929 company-owner cases, 59% of which also show another financial distress signal (GalimAI data, as of July 2026).
• 224,113 owners hold property rated below EPC C ahead of the proposed 2030 minimum standard (GalimAI data).
• 5,365 owners hold an EPC F or G property with less than £5,000 cash and sub-£5m net assets, unable to fund the fix, re-let, refinance or sell as-is (GalimAI data, updated 8 August 2026).

Waiting for a listing means competing with every other buyer at the exact moment a seller finally goes public. Reading the signal a year earlier is what turns a 15.8% market share into deal flow, rather than a statistic.

Common questions

What percentage of UK property sales are off-market?

Nationally, 15.8% of England and Wales residential sales took place off-market between 2022 and 2024, according to TwentyEA's Property and Homemover Report. That share fell sharply to 11.4% in 2024 alone as the supply of new listings improved.

Are off-market properties cheaper than listed ones?

Not automatically. TwentyEA's data shows off-market activity is concentrated above the 1 million pound mark (20.1% of sales), where discretion drives the decision rather than price. Below 1 million pounds, only 6.7% of sales are off-market, and sellers there generally rely on open-market exposure to secure the strongest price.

Why did the off-market share fall in 2024?

TwentyEA found new instructions rose 10% in 2024 compared with 2023, giving buyers more choice and reducing the competitive pressure that pushes sellers to skip public marketing. Average time to sell also lengthened, which favours a full marketing campaign over a private, unadvertised sale.

How does GalimAI find off-market sellers before they list?

GalimAI reads distress and life-event signals, including probate, insolvency, tribunal penalties, late Companies House filings, over-leverage and EPC non-compliance, across more than 460,000 property-holding companies in England and Wales. That surfaces owners likely to sell months before any transaction, on or off market, actually takes place.
