THE PROPERTY FILTER TAKE
New UK property listings rose 2.6% to 209,941 in July 2026, while sales agreed grew just 1.1% - conversion rates have eased to around 50%, per PropertyWire (August 2026).
Supply at a seven-year high with a lengthening average time to sell means buyers hold more negotiating power than at any point since 2019 - the opportunity window is open.
You may wish to consider targeting motivated sellers in high-supply areas where days-on-market is rising fastest, and running deal numbers through a stress test before committing.
New UK property listings hit 209,941 in July 2026, up 2.6%, according to PropertyWire (August 2026). Sales agreed moved just 1.1%. The conversion rate (the share of listings that turn into agreed sales) has eased to around 50%. Supply is at a seven-year high. Sellers are working harder. Buyers have more room.
The Supply Gap That Shifts the Balance
When listings outpace sales at this rate, the balance changes. Sellers face more competition from other available stock. Marketing periods stretch. Price conversations open up. That is not a warning for buyers - it is an opportunity.
The 2.6% rise in listings, reported by PropertyWire, pushed total stock to 209,941 across Great Britain in a single month. Set against just 1.1% growth in sales agreed, the maths is clear: more choice, less competition per property, more room at the negotiating table.
For investors running deal sourcing pipelines, this is data worth acting on. More supply means more motivated sellers. More motivated sellers means more deals worth chasing.
Conversion Rates and What They Tell You
A 50% conversion rate means one in two listed properties is not selling. That is not noise - that is signal.
In a balanced market, conversion sits higher. Seven years ago, the last time supply levels were this elevated, asking prices were tested and discounts appeared. The current picture has the same fingerprints.
The average time to sell is also lengthening, per PropertyWire. That matters for property investment strategies built around buying below market value. The longer a property sits unsold, the more the seller's position shifts. Days on market is one of the clearest indicators of a motivated seller.
Use Property Filter's deal sourcing software to filter by days on market. Properties sitting unsold for 60-plus days in high-supply areas are where the margin conversation starts.
Where to Point Your Pipeline
The opportunity is not uniform across Great Britain. Supply at a seven-year high is a national headline. The action is in areas where listing growth has outpaced even the 2.6% national average and where days-on-market is climbing fastest.
Here is the angle: search for sellers in those areas who have relisted or taken a price reduction. Stack that with properties priced above the local median. That is a concentrated version of what the broader data is flagging.
Before committing, check your finance assumptions. A lengthening time-to-sell affects bridging exit timelines and refinance windows. The stress test calculator is worth running before you move.
