CoStar Data Shows Midlands Big-Box Market Reaches Turning Point as Supply Starts to Fall

LONDON--(BUSINESS WIRE)--Big-box warehouse supply across the Midlands has begun to fall after the turn-of-the-year peak, according to data from CoStar, a global leading provider of online real estate marketplaces, information and analytics in the property markets.

Availability has fallen by around 5m sq. ft. in recent months due to stronger occupier demand and a moderating construction pipeline, following a prolonged period of rising supply. Despite this decline, it remains historically high at around 30m sq. ft.

“Many occupiers are now moving earlier to secure space,” said Grant Lonsdale, senior director of market analytics at CoStar Europe. “This is particularly evident in established distribution locations with strong motorway access, driving around 6m sq. ft, of take‑up across the Midlands in the opening months of this year.”

At the same time, construction activity has slowed markedly, with around 70% of the region’s big-box space under construction pre‑let, limiting new availability in the coming months. At 9.3m sq. ft., the pipeline is 40% smaller than two years ago and half its 2022 peak.

“Tightening market conditions are likely to stabilise incentives and rental levels after a period of subdued activity,” said Lonsdale. “While rental growth may remain selective and scheme‑specific, the balance of power may be beginning to shift modestly back toward landlords, particularly owners of high‑quality warehouses.”
