Working from home some of the time, or hybrid working, will become "the norm" for many companies after the pandemic, says global workspace provider IWG.
Firms will be looking to save money and be more environment-friendly by using less office space, said IWG chief executive Mark Dixon.
IWG said 2020 had been a "challenging" year as fewer firms rented its offices.
But it said it was ready to take advantage of "accelerating demand" for hybrid working.
"Something's happening and it is a change to the way that companies and people work," Mr Dixon told the BBC's Today programme.
Mr Dixon said companies were keen to shed some of their office space and use third-party facilities instead, often closer to where staff actually live.
"It works for companies, because it's a lot cheaper," he said. "It's also much, much better for the environment," he added, as it enabled workers to cut back on commuting.
One big UK employer, the Nationwide building society, has indicated that it does not intend to force people to return to the office if they have been successfully able to work from home during the pandemic.
Its leader of people and culture, Jane Hanson, told the BBC that about two-thirds of its 18,000 employees had been working from home for the past year.
"We won't be asking them to go back to the office and we've given people a commitment at the moment that the current working practices will continue until at least June, whilst we're working out what the future looks like," she said.
