- Customer contacts ISP and signs up to a UFB plan.
-ISP contacts Local fibre company and requests connection and ISP pays fee to LFC. This step including the amount of the fee is the same regardless of whether fibre is already installed to the property or not.
-LFC provides connection between ISP and end customer via UFB (including installing the fibre if not already installed)
In otherwords [AFAIK] it is not possible to get fibre installed without also requesting a connection. And if you will be selling soon it will probably be better to not get fibre installed. So the new owners can decide where they want the ONT to go. Considering that you have said that you don't want fibre for yourself. As it will probably be expensive to have it moved. (I agree with everyone else that getting fibre is still a good idea compared to ADSL)
For the record, Does anyone know how much it would cost to get an ONT moved? Assume a single level house, good underfloor access. Move ONT from 1 side of lounge to the other side. Due to ONT currently being installed on wall between lounge and kitchen and this wall is being completely removed. This scenario is completely theoretical BTW. But it is only a matter of time before some asks a "how much to move a fibre thingy [ONT]" question. (hopefully that is enough detail for someone to give an educated guess).
