you need to decide which ISP you intend to us then order a phone line once you have the line then as @pippincp says openreach database will get updated and then you should be able to order broadband from ISP who you have phone with
As an ordinary consumer who has been through this with 3 new builds, I know this is a hugely frustrating chicken-and-egg situation. Essentially we would like to be able to make a free choice over broadband ISP, probably combined with other related services such as landline for value and simplicity. The trouble is, as @imjolly has said, you have to commit to a landline provider before the next step can even begin! In hindsight, when everything is eventually in place, you could well regret your choice of landline provider but what else can you do?
Talking to the neighbours is a great start - but bear three things in mind: firstly there can be odd variations in service availability even from one property to the next; secondly your neighbours' wants, needs and expectations may differ significantly from yours; finally, available deals can vary considerably from week-to-week, never mind as long ago as your neighbours package was agreed.
