UK Census to be completed by 21st March

Thanks for John Cleary for sending this reminder.

Whilst all the Brits stranded on Madeira scramble for flights home, they need to fill in their UK CENSUS form by 21st March, they don’t have much time and can be fined up to £1,000 if they don’t.
They need the 16 digit number that would have been sent to their home address.

Has everyone done this? might be a bit difficult for some if they can’t get their code number to do it.
