So there are two types of internet for the most part - fttp and fttc. Fttc means fibre to the cabinet and means its fibre optic to your local cabinet and then copper wire to the house
These are generally provided in the openreach network - generally tops out about 76mb or so. Will be offered by BT, sky, plus net, Vodafone etc
Then there is fttp which is fibre to the property
This can be in the openreach network if they've upgraded, or or could be virgin or it could be altnets like youfibre or cityfibre
If you go here : https://labs.thinkbroadband.com/local/broadband-map#6/51.414/-0.641/and
click the button on the map that says fttp isps and then select all and zoom in on your street you should see what's around. It might be cityfibre or some other altnet is building nearby
I used this to track youfibre coming into our area (Ingleby)
It might be that for true high speed virgin is currently your only option. We moved here in 2018 and from then til may last year 76mb openreach was our only option. Virgin installed to our street in May but by then I knew youfibre were coming
Your other options are 5g dongles, but rely on signal.
Or final option is to look at Musk's star link, but it has high set up costs.
