It is an offence to supply false information or to not complete the census, and you could be fined up to £1,000.
The majority of the questions are compulsory, meaning that the householder should answer all of the questions on behalf of the other household members, or ensure all members answer their own questions, i.e the ones about dates of birth.
The questions within the census aren’t difficult and shouldn’t take long to complete.
When do you have to complete the form by?
March 21 is Census Day, which is the ONS’s preferred date for submission, as they’re using today as the one day to capture life in 2021.
Any time as soon as possible following this date should also be okay, with online forms being allowed for submission until early May.
