 That has never been my experience. Whenever I've "upgraded" a service with Virgin a new 12 month contract followed. It happened when I went from L to XL about 5 years ago. It also happened when I went from 20mb broadband to 50mb broadband.
Section H of the terms and conditions seem to suggest you need to keep any new services for their minimum term.

You may add to or reduce the services you receive from time to time by contacting our customer services team. If you ask us to provide any extra services to you, you agree to accept those additional services for at least the minimum period that applies to them. If you ask us to reduce your tier of services within the minimum period for those services, we may ask you to pay a fee depending on the services being reduced and the remaining length of the minimum period.
