It looks like you are located somewhere in the UK, based on this link for Virgin Media:
http://www.virginmedia.com/
When I entered Richmond, UK (that is where our oldest son lives) to find locations of Virgin Media stores, at least 4 appeared close by.
In any event, Virgin Media would be your ISP (assuming you have a Virgin Media EMail address; my ISP is Comcast, and my Comcast EMail address is (e-mail address removed)). But the process of how you receive EMails has a few variations:
1. You can choose to receive your EMails via your Virgin Media EMail address. And you can "link" EMails received on your other "accounts" (gmail, hotmail, yahoo, etc.) to that address (actually, to the EMail program you are using). In that case, when you launch your EMail program, you would see all EMails sent to any of those accounts that you set up.
2. You can instead choose to just receive EMails to your Virgin Media EMail address, via your EMail program. For gmail, hotmai, yahoo, etc., you can access those EMails through your browser.
I myself use option #2. My ISP is Comcast, and I choose to receive EMails, through my ISP and with my EMail program Outlook 2016, for ONLY those EMails addressed to my Comcast EMail address. For my gmail and hotmail accounts, I access those sites/EMails through my browser, Google Chrome. I prefer to do it that way because 1) my Comcast EMail address is the one I use for "official" correspondence, exchanging EMails with friends, etc., and 2) the gmail and hotmail accounts are used for non-important purposes. Also, this cuts down on the spam I receive via my Comcast EMail address. (I actually can also access my Comcast EMail via their site, but I much prefer to do it via Outlook 2016).
What exact steps do you go through to receive your EMail? Do you launch an EMail program (like Outlook 2016, Apple's Mail Program, Thunderbird. etc.), or do you go to a site via your browser (like I do for my gmail and hotmail "accounts")?
