put your address in here , on here is the information Openreach have as far as what was discovered at survey , and therefore what’s required to get service to the individual property , it also has the installation process , required for the ISP so they can advise their customer how the work will proceed , the installation process is either KCI2 assure ( a two stage installation ) , or single stage , all work can be done with a single visit …..what does your address show , if KCI2 , then the first visit from Openreach isn’t a contractual date and isn’t the date service is to be expected, but the date the preparatory work starts (which seemingly in your case requires excavating the road/footpaths ) , the existing service isn’t ( or shouldn’t be ) affected by this , it’s only the first stage of two , even then , as previously described, there are ‘failsafes’ in the migration process anyway .
What does your survey network note show , a SNN looks like this ,
Our records show the following FTTP network service information for these premises:-Single Dwelling Unit Residential UG Feed with no anticipated issues.
This one is for a modern fully ducted property, yours will differ but what does your address show , if it’s something like ‘UG partial DIG’ then the complexity of provision was known in advance, and any date is provisional until the mitigation is put in place ( the physical work to enable a cable to be fixed to your address )
What is your installation process, single stage or KCI2 ?
