Wayleave issues shouldn't usually occur with individual houses like they do with block of flats.
Are these houses managed by a housing estate management company? If yes, then contacting your local housing officer will be more helpful.
But if it is not, then the wayleave issue may not be related to your house but more related to somewhere on the streets that require local permission.
If Openreach are proposing to install by December 2026 then they may be facing a similar problem to CityFibre and the rollout may be delayed in the same way.
In my case I live in a block of flats and I had wayleave issues with Hyperoptic. Wayleave was never granted despite me being a registered Hyperoptic Champion 10 years ago and getting my neighbours to register their interest made no difference. In the end my management only granted wayleave to another Altnet Community Fibre and most recently Virgin Media nexfibre.
It is very much possible that wayleave can be granted for one Altnet provider but be totally rejected for another and contacting the ISP or network provider is futile because often they don't know why a housing estate is refusing them. Just like I never knew the reason why my management were so against Hyperoptic such explanation was never given.
But obviously in your case the situation may be totally different as you live in a house and not in an MDU. Unless the houses are Multi Dwelling Units like houses not being individually isolated but connected one next to another then this may have issues that require wayleave permission.
