Virgin Media said the average household has used an extra 325GB of data since 23 March when lockdown started.
April was the company’s busiest month on record and usage in May was just slightly behind that, as more people are now working from home.
More children are now having classes remotely and are downloading more programmes leading to an extra 3.4GB on average per day due to the lockdown.
23 to 29 March was the busiest week for the broadband provider which saw people downloading around a third more data than before the lockdown, consuming an extra 32.5GB.
London saw the highest jump with an increase of 20% whilst Wales saw a 10% increase and Scotland downloaded the least.
During the crisis customers uploaded an extra 3.7GB per week, and Northern Ireland saw the largest increase by 58%.
Jeanie York, Virgin Media’s chief technology and information officer said, “Despite a surge in demand as people have relied on their broadband more than ever, our network has proved itself reliable and resilient and helped keep people connected to loved ones, work and entertainment.
“This is a new dawn for broadband usage; the way people use their connectivity has irrevocably changed and we expect Covid-19 will have a lasting impact on patterns of data consumption.”
