London landlord Great Portland Estates has said that just over a quarter of workers are back at their desks at its offices despite all of its buildings being open.
The update from the West End-focused property group highlights the difficulties facing city centre economies, after Boris Johnson was forced into an about turn on getting staff back to the office last month.
Firms are prolonging a return to the workplace or ditching the office altogether as virus cases continue to surge for a second time.
The Telegraph revealed over the weekend that Lloyd’s of London, the world’s largest insurance market, is looking to abandon traditional office working even after restrictions are lifted following the success of remote working.
Britons are some of the most worried citizens in Europe about returning to the office, with fears over public transport putting many off getting back to their desks.
It came as Great Portland reported that rent collection from tenants in the hospitality sector plunged in the three months to the end of September.
While it collected 73pc of total rent due for the quarter including deposits, only 28pc had been collected from hospitality tenants, including pubs and restaurants.
The company said it was helping struggling occupiers to pay rents through monthly payment terms, deferring rental payments or providing rental holidays.
Two of its tenants went into administration during the quarter, it said.
Chief executive Toby Courtauld said: “Whilst rental collection and occupancy rates have improved across the portfolio since March, many sectors remain challenged.
“We continue to engage with those occupiers unable to meet their rental obligations, offering assistance on a case by case basis to support them through this difficult period.
“Whilst we expect the near-term outlook to remain unpredictable, we remain firm believers in the long-term appeal of well-designed and located offices and of London's role as a dominant global city.”
