The Openreach website does not show your postcode as a plan for 2026 but it can change at any time. It simply means you may not get it by December 2026. But then I've seen surprises where it shows no plan and people get upgraded earlier or unexpectedly compared to some that do show as planned.
However, I found out that you have OFNL and nexfibre available both of, which are wholesale FTTP providers.

These are the ISPs you can choose from

You also have Virgin Media Gig2 available. VM is currently the only provider available on the nexfibre network.
Open Fibre Networks tend to be some of the most expensive packages that I've seen based on comparisons. Every ISP on OFNL gives a worse deal compared to any ISP on Openreach, CityFibre or any other Altnet. Even Virgin Media has better deals than OFNL.
Indeed Openreach is a far better choice but we don't know when they'll roll out. Most of us don't have the power to influence what FTTP provider will come to our area. We get given whatever is provided and we don't have much of a choice.
