The London Office Market Report - Q3 2025

Knight Frank's Q3 2025 London Office Market Report assesses conditions in the London office market, finding that despite persistent inflation at 3.8% and elevated interest rates, London business activity outpaced other UK regions for a third consecutive quarter, with take-up reaching 2.7 million square feet (down 23.3% quarterly but 19.8% ahead year-over-year). The report identifies softer leasing activity, a constrained development pipeline, falling investment volumes of £1.6 billion (offset by rising assets under offer at £3.0 billion), and overall market resilience marked by improved sentiment, though vacancy rates increased marginally to 9.0% and structural undersupply of best-in-class space is projected to persist through 2029.
