It depends, how is your phone line supplied at present, underground or from a telephone pole? If from a pole and Openreach can get the fibre into your house easily and install the FTTP ONT where you would like it then it will be straightforward. On the other hand if you are supplied by direct buried underground cable with no ducting then it could be a problem and they may refuse to install it.
Assuming you can get FTTP what does the checker text say about the installation. Look below the speed estimates in the text where it says FTTP is available.
