To begin closing your Nutmeg account, you should first request a withdrawal of all your money from each General or ISA pot you have. Just select withdraw from the Options button on each pot. More: Withdrawing money from Nutmeg
If you have an ISA with us, be aware that the current year's ISA allowance will remain used if you withdraw from your ISA. If you want to maintain the ISA status of your money you can request an ISA transfer out to another provider.
Once this is done, send us a Nutmail with the request to close your account. We will contact you to confirm your decision before deactivating your account.
Your account will be deactivated entirely no later than six months after the request, to allow for final payment of all dividends and interest income which you may still receive from the investments you owned.
Current regulations require us to retain records even after you have closed your Nutmeg account: Records retention
