When OpenReach FTTP came to our area we didn't have any flyers to tell us it was available - I only knew as I happened to go on the BT website to check package availability.
CityFibre and VodaFone may be more keen to try and make a recovery on their investment - the "good" news is there are fewer suppliers on CityFibre and so you aren't likely to get that many different ones through the letterbox, but no idea how aggressive CityFibre ISPs are at marketing.
Vodafone will be over Openreach FTTP here as we don't have city fibre, so no investment here, it will be openreach that have done the investment, and Zzoomm for their network
We will see how many we get in the next few weeks and from whom, I am surprised I have got nothing from my own broadband provider yet.
Vodafone seems very random, it is not really a provider most people would link with broadband, not that I would ever have a service from them again.
