My current contract is ending in September, and I want to change to the £7/m SIM-only. When and how should I do that so that the transition is seamless and doesn't cost me any excess money?

When you are at upgrade page you can sort it by price from low to high when you do it sim only offers should come up at the top.
In case if you still don't see Sim only upgrades in your app, you could call sales team at +44800 049 0250 and they will be able to help you.
