look up the ONT internal shift price , this is the price OR charge the ISP , the ISP price can be whatever they see fit …there is no need for a survey fee as such in these circumstances , how you even got a price from Openreach directly is a mystery as they should not be entering in to a dialogue, and have no way to raise a bill for the work , I’d suggest they have used the wrong processes to arrive at a price ….
if VF your current provider won’t arrange the ONT shift , then migration to BT may work but that’s something of a leap of faith on your part , you are not likely to get either an agreement in advance of BT arranging this , or the right to quit penalty free if BT don’t arrange it .
A way to get this done , for a similar price to the shift but unfortunately with some ‘down time’ is to report it faulty , to do this you would either need genuinely to damage the cable so the ONT isn’t connected, or power off the ONT and say the cable is damaged , when the tech arrives you ask for the new cable to be routed differently from the existing cable route , obviously if you report it faulty when it’s not , it’s entirely possible that the fault would be cancelled as it can be checked if the ONT is ‘talking’ to the headend, so you would have to leave the service ‘off’ for at least some time
