CoStar Office Market Activity Tracker: Manchesterism and Midlands markets move up the rankings

Several UK office markets have seen robust demand in the first half of 2026, although performance remains polarised. CoStar’s latest Office Market Activity Tracker highlights the high ranking of Manchester and several midsized Midlands markets. While London leasing remains strong in central submarkets, it slipped back from the top spot based on other metrics. Meanwhile, Oxford and Cambridge face rising vacancy pressures as completions outpace net demand.
