Leaving Virgin Media

my contract with VM ends in early March and I don't want to renew it

This is another popular misconception. The only contracts that expire & need renewing are fixed-term ones. VM's contracts, in common with the rest of the UK telecoms industry, have ongoing rolling contracts with a minimum-term.

It's that minimum-term that many users confuse with "contract end".

Hi Steve,

First things first. You say you have a hub and 3 tivo boxes.   That is incorrect, you don't have tivo boxes.  You either still have 3 V6 boxes, or you have TV360 boxes.  The original tivo boxes don't need returning when you cancel, however both the V6 and TV360 boxes need returning along with your hub.  (You had a number of posts around 5/6 months ago about the process of moving from V6 to TV360)   TV360 boxes have a remote control with a voice button.

To cancel you can either use the OTS  (One Touch System) to leave as explained by Ofcom

Or you can give VM a minimum of 30 days notice (60 days maximum)  as explained on the following page https://www.virginmedia.com/help/leaving

VM don't come to your home to uninstall the equipment, you do that yourself. As part of the cancellation process VM will send yuo returms packaging around 10 days after the account is closed.  You can either return the requested equipment in the returns packaging via your nearest local Yodel pick up point, or a local O2 shop.

The following page shows the equipment that needs returning, along with additional links to request packaging or print out your own returns label.
