Alistair Brown, head of London markets at Cushman & Wakefield, said: “There is no disguising that 2020 had been a tricky year for London’s occupational markets. Many 2020 business plans were upended by the Covid-19 pandemic; a shift to home working, the logistical challenges that created and the pressure of a less favourable economic environment meant that a significant number of plans were suddenly put on hold or reconsidered entirely.”
