This isn't true everywhere in the UK. Neither Openreach nor City Fibre have laid fibre in my area of a big city, the only date given for when they will do it is sometime before 2026. A dedicated fibre internet company has cabled my street though. I just switched from an ISP that uses the Openreach infrastructure, probably the same one you are using from your description, to the dedicated fibre internet company as it was the only way I could get a faster connection.
