With speeds that slow, it seems obvious that the fibre optic cable being nearby is purely academic and that you're connected to the nearest BT phone exchange by however many miles of copper wire that might be. I'm only 1 mile from an exchange, the other side of town and I get only 7/8ths of the speed I pay my ISP for (monthly useage is unlimited).
First port of call is your service provider. Ask if your speed has been "choked" for any reason. They get fined less if they provide a reduced-speed service to hundreds of customers rather than provide service as advertised to customers near the phone exchange but zero service to remote places, such as where you are. This is a roundabout way of getting them to admit that they have customers with even worse speeds than you are getting.
Ideally, it is a localised line fault, or problem at the phone exchange and your call will prompt them to get it fixed.
