London offices worth £5bn are for sale as the market enters a “key” few weeks.

Large deals, including the £512m Schroders’ City HQ, are being watched closely to see what appetite investors have amid rising vacancies and the uncertainties of the pandemic.

Knight Frank said that in addition to the £4.9bn of available stock, nearly £3bn of buildings had been placed “under offer” by purchasers and were close to being sold.

“The next few weeks are key,” Nick Braybrook, head of London capital markets at Knight Frank, said. “There are a number of large transactions that are under offer and approaching deadlines. As these transactions sign, it will be a shot in the arm for more activity.”
