London Commercial Property For-Sale Listings Fell 11.4% While Prices Rose in the First Half of 2026

London Commercial Property Trends: For-Sale Supply Tightens as Prices Firm

In the first half of 2026, LoopNet listing data shows commercial property for sale in London thinning while asking prices held firm.

That trend came amidst the weakest nationwide credit conditions since Q3 2023, according to RICS's UK Commercial Property Monitor. And London's leasing market further supports the link, as the city's leasing supply rose 2.6% over the same period that the for-sale market contracted. Tighter credit weighs more heavily on debt-funded acquisitions than on leasing decisions, a plausible read of why the for-sale market cooled.

For-Sale Listings Fell 11.4% While Asking Prices Rose 8.1%

LoopNet recorded 904 commercial properties for sale in London in January 2026. Over the first half of 2026, that figure fell 11.4% to 801, and the sharpest monthly decline arrived in June.

Over the same period, average asking prices per square foot increased 8.1% from £405.28 in January to £438.18 in June. Most of that rise arrived by March; prices then peaked near £446 in spring before easing to the June figure, so the headline number reflects an early-year step up more than steady momentum.

An 8.1% rise in average asking price may reflect a shift in the mix of listed stock toward larger or more central assets as much as broad repricing, so it reads best as a firming signal, not a precise gauge of value growth. Either way, fewer listings alongside higher asking prices point to a for-sale market where available stock is contracting.

London's office stock, which drives a large share of the city's commercial market, mirrored that broader commercial property trend. Savills's Central London Office Market Watch reported that Central London office investment turnover ran well below its five-year and 10-year averages early in 2026, with smaller average lot sizes as buyers turned more selective.

That subdued deal flow is consistent with what LoopNet recorded. Savills reported the number of assets traded ran below its 10-year average, so the decline in listed stock is unlikely to reflect unusually brisk sales activity clearing the pipeline. That combination points more toward owners holding back from listing than toward a wave of completed deals, though LoopNet's data alone cannot confirm which mechanism is dominant.

By June, listings had fallen 11.4% while average pricing was up 8.1%, having peaked near 10% in spring.

Cap rates held steady even as available stock declined.

Seller-reported cap rates barely shifted over the half, holding in a narrow band between 6.38% and 6.53% and ending at 6.47%. The LoopNet data shows London's rates sitting below those of every other UK region, which may reflect the pricing premium investors place on the capital, though as seller-reported figures they warrant some caution.

That broad stability fits CBRE's UK Real Estate Market Outlook 2026, which expects rising rental values, rather than sharp yield movement, to drive the UK recovery. Cap rates measure the income return on a commercial asset relative to its value, similar to net initial yield in UK practice, with slightly different inputs.

What the London Data Means for Investors

Two points stand out from the first half of 2026 data:

• For-sale supply contracted while asking prices climbed, leaving a smaller pool of London acquisition opportunities over the first half of the year. The best-priced stock is likely to clear quickly, since fewer owners appear willing to add new listings. Rising asking prices point the same way: even if partly a mix effect, they suggest real demand for what remains.
• Seller-reported cap rates stayed close to 6.5%, holding steady even as supply and pricing shifted, which suggests investors are pricing continued demand rather than added risk. That balance would come under pressure if borrowing costs rise, since higher financing costs typically push required yields up.

The data favours well-priced for-sale opportunities in a market where available stock is thinning. For those who already own London assets, firmer average pricing and steady cap rates may support a fresh look at current valuations, even if some of that price firmness reflects the mix of listed stock rather than pure appreciation.
