No they won't.
This is what happens every year it would seem from looking at other forum posts and here is my experience from this morning. It appears to me like VM are making it very difficult for existing customers to plan / understand what deals are available to them – forcing them to call and not allowing them to make make clear and informed decisions about whether or not it makes sense to re contract.
Here is a screenshot of the "re contract" email (received April 2024) – encouraging me to find out what "exclusive offers" are available to me as an existing customer:
Here is the error page when clicking any of the recontract now buttons :
I've also tried logging into my account and stepping through the wizard, encouraging me to login to My virgin media - which I did ...
After logging in I was redirected here and clicked the "See my offers" button (for clarity, again, I was logged in): 
I was then redirected to the same error page above.
I was forced to call ... and as an existing customer still in contract, was offered only ONE DEAL. That deal was the same package (but with TNT sports removed). It was double the cost of my existing deal. I said I was not willing to take that deal and was told there was nothing else I could do other than to cancel and pay an early cancellation fee, or to "call again in May to find out what offers were available then when there may be better deals" (as opposed to new customers who can browse the website and make an informed, fair decision).
I asked if I could downgrade my or package and was told that was not possible at this time. I then tried to change my own package from my virgin media account - and reached the same error page again, as above.
Basically, as an existing customer - I have no way of downgrading, or viewing offers available to me when my contract comes to an end. But, as an existing customer - I can clearly see and plan ahead.
This is terrible customer service and gives existing customers nowhere to go other than to leave Virgin Media and seek an alternative service. The fact similar threads exist from 2022 regarding the recontract / exclusive existing customer offers error pages – makes it pretty clear that no effort is being made to make this easy for existing customers or, what's more likely, is this is a deliberate attempt to make lives difficult for existing customers, forcing them to just accept a new contract at double the price when they come close to their services being shut down.
