Seemingly, the only difference between their offering and the likes of BT is that they are subsidising the cost of the line. As such, availability of their fibre is just like any other, which means many people in SE1 will be out of luck due to the prevalence of exchange only lines in the area.
Be careful with the check availability page on vodafone as well; they collect far more personal information than is needed to tell you what services you can get.
My advice is to use this checker: https://www.btwholesale.com/includes/adsl/main.html
If that says you can get fibre (just your telephone number required there) then you can choose any fibre provider you like (including vodafone)
