You can use My account to change or amend your details and add to your policy before you renew it.
There are a few changes you can't do online, though. Please email us at firstname.lastname@example.org if you want to:
change policyholder's or additional policyholder's dates of birth
change number of years without claims
remove claims (you can add a claim via My account)
It's not possible to change the main policyholder. If you need to change that, you'll have to cancel your existing policy by logging to My account and then take out a new policy with amended details.
