The research comes as more people work from home or split homeworking and the office following the pandemic.
Some 77% of those surveyed by BT said that a strong wi-fi connection is “definitely important” when it comes to good work-life balance.
Almost two thirds (65%) of those polled claimed that weak wi-fi has restricted them creating their own home office or workspace.
While 75% of Londoners believe having a “multi-room” homeworking set up increases productivity and creativity.
The office (38%) living room (21%) and bedroom (16%) take the top creative spots around the home, the research found.
BT released the research, based on surveys of 2,000 UK residents, to support its Complete Wi-Fi - that extends the existing home broadband signal to offer a strong and seamless connection throughout a whole house.
Matt Hughes, Broadband & Home Director at BT said: “We want our customers to feel as productive and creative as possible, so it’s important they have an internet connection that helps them do this.”
