Dear all, thank you all so very much for taking your time to help me with my questions I had about this post. Cerberus got back to me saying this below:

I do not think I will go ahead with a full survey as this has been emailed to me:

I have kept in touch with Mr Sharpe (the man who sent the email seen above) and he said he is going to inform me of the price and depending on it Openreach could cover some and I cover the rest however this is just an idea.
Once again thank you all so very much!
