Office properties in the UK are selling for nearly 20% less than their owners' expectations, marking the largest discount since the 2008 global financial crisis. This significant price drop, highlighted by CoStar's data, reflects weak demand, particularly for older and less environmentally friendly buildings. Notable sales include 140 Leadenhall Street in London, which sold for about £20 million against a £30 million asking price, and Oxfam House in Oxford, which sold for £37.1 million, down from a £60 million asking price. The office market has been sluggish due to rising interest rates and post-pandemic uncertainties. While demand for modern, eco-friendly offices is growing, secondary offices are struggling to find tenants. CoStar estimates that 8.3% of UK office space is vacant, the highest in 11 years. Some landlords are selling at lower prices to avoid costly refurbishments, and even "grade A" offices are tough to sell. Despite a recent interest rate cut, the market remains slow, with some high-profile sales being pulled due to lower-than-expected offers.
