You've got to appreciate most of the services provided travel over the exisitng network. FTTC is deployable, without customers paying individual installation costs, as the bulk of the network it upgrades serves many in an area and gives an uplift in future capacity (more chance for OR to recoup costs); ie Openreach will go to the expense of installing fibre cable, new cabinets, new ducts etc when they can spread the costs to many customers over a given time period (I'd guess up to 10 years). The last leg to the property is copper, which either already exists or is relatively cheap to install (ie its only the cable, poles or ducts already exist to serve that area)
In general, with FTTP, which feeds off the back of FFTC, openreach have to install fibre all the way to the property, may have to install new (buried in the ground) ducts etc... All this costs and needs paying for... you can use the FoD process, but be prepared for a significant bill ( i think fibre is £30 per metre alone, if laid through exisiting ducting). Openreach will provide and intial estimate prior to performing a full ground survey for your installation needs. Be aware this survey costs too.
If you are in need of it speak to Openreach... https://www.openreach.co.uk/orpg/home/products/ultrafastfibreaccess/fttpondemand/fttpod.do
ISPs can't provide a service when the capability doesn't exist, nor are openreach mind readers. Only Openreah can solve your needs for FoD, on their network. I wouldn't of expected ISPs to know of or suggest FoD, unless they were buisness lines only orientated.
If the OR network does not meet your needs (whether that's costs or their network deployment methodolgy), try one of the other providers, such as Virgin fibre.
