A statement from the ICO responding to an article that shows that fewer than 1 in 5 sites have complied so far to the new cookie law.
We are conscious that many websites are still developing solutions to become compliant with the new rules and this survey shows that, for many UK organisations, there is still some way to go.
We gave UK websites a year long lead in period to comply with the new changes and we expect organisations to have used this time productively. Now that the lead in period has expired, organisations should have robust and effective plans in place to comply with the new changes. This means making sure visitors to their website are given clear information and the necessary options to control the placement of cookies.
Where it is clear that an organisation is failing to be open and upfront with users about how cookies are used on its website and has no plans in place to comply with the new changes, we will consider taking formal enforcement action.
