From 25 July, Ofcom required websites operating in the UK with pornographic content to “robustly” age-check users, under the Online Safety Act.
Some people began using a virtual private network (VPN) at this time – tools which can disguise your location online to allow you to use the internet as though you are in another country.
The increase indicates people are likely using them to bypass requirements of the Act.
After the age checks became mandatory, the survey said VPN use more than doubled, rising from roughly 650,000 daily users before July and peaking at over 1.4 million in mid-August
But it also found the number had since declined to around 900,000 in November.
