I'm an existing customer with an account for an O2 SIM for one of my phones. I'd like to order a new O2 SIM for my other phone.
Can I do this on my existing account, or do I need to create a new account?

You can use existing account. Just choose an additional number rather than an upgrade.
You will also get better deals on USwitch.
https://www.uswitch.com/mobiles/compare/sim_only_deals/o2/
Choose the deal you want
This will automatically redirect you to the O2 website
Just follow the prompts and choose the UPGRADE option
Complete the deal and nothing on your account changes except the tariff at the new cheaper cost
Payment date is the same and your next bill will be at a cheaper rate and will be made up of the pro rata cost of your old tariff and your new tariff
The change should show in My O2 within 24 hours
Volt benefits will still apply as will possibly a 3 month extra such as Disney+
