If your area was correctly surveyed, then it would be known that your address is currently served with a D.I.G ( direct in ground ) copper pair armoured cable , when the area was made FTTP ready , a civils contractor should have provided duct from a jointbox to a new toby box ( similar to those that the cable industry use ) usually placed in the footpath adjacent to your property,
If / when FTTP service is ordered you should get another individual survey, this time from the Openreach installation people , who should discuss how service will be delivered, this normally would be by digging a small trench from the toby box to your house wall , this needs permission from the householder who may have restrictions on how the trench is provided ( like avoiding shrubs/ landscaping etc) …the civils contractor are advised where the original surveyor wants the toby box positioned, so as to provide the easiest install ( like opposite grass rather than a driveway for example ) but other services in the footpath could mean the toby box cannot be placed where the initial survey team wanted it.
If you agree to the excavation etc. through your garden , then the order proceeds , in the unlikely case that you order service but then refuse permission to dig, then the order would be cancelled , if the reason is your refusal obviously there is no compensation etc,
Try putting your address details on the DSL checker

If FTTP is available your address it should say something ‘UG feed to curtilage hard’ which signifies to the ISP that it’s a two stage install and they shouldn’t give a proper appointment for service , but an appointment for the survey, if the DSL checker states something else then the initial survey was incorrect
…have you noticed a toby box installed near your home ?, usually there is one per property, but you can also have one toby box placed midway between the gardens of two property’s and that can serve both
