You can change the address on the desktop version of InvestEngine by going into Settings. You can find it by clicking on "Hello, your first name" in the top right-hand corner of the screen. Your contact details will appear on the new page, where you will be able to amend them, including your address.
Most addresses get verified automatically, however sometimes you will be prompted to upload a proof of address. We accept driving licence, bank statement, utility bill (water, gas or electric only), as long as they are dated within the past 3 months.
