It’s a pretty complicated business, if your installation was flagged as a two stage install, then it was known of the potential for delay ( that’s why it’s not a single stage installation ) , the first date given in these cases isn’t contractual but often it isn’t pointed out . Once whatever the issue is causing a two stage to be necessary ( excavation read to get duct to the house for example ) is resolved, the second stage date is contractual date …..there is also the option , in single stage installations where an unforeseen obstacle stops the installation happening ( on the single stage contractual date ) , the order can be cancelled to stop the compensation clock , and then if a 4G mobile device is provided to get over the gap ( this is more when a brand new service is delayed , not so much on an upgrade if the previous FTTC/ADSL is still working ) then arguably compensation isn’t due as connectivity was provided or maintained , in those cases a goodwill payment may be offered but not the Ofcom scheme level of compensation.
If no automatic compensation was applied , call and ask .
