Hello. I am a solicitor with over 15 years experience. I will try to help you with this.
As far as light in the back garden is concerned you have no right to this. I am afraid there is also no right to an internet signal.
If the vendor has made representations or answered enquiries in the course of the sale which are not true you may have an action against him for compensation for the lack internet access or to pay for whatever works are necessary to ensure an internet connection. However it will need to be a clear falsehood. If eg he could get an internet signal when he sold it but now you can't then there will be no action.
It may be that your neighbours are in a similar situation and you should band together to put pressure on the seller. Did your solicitor make an enquiry re internet connectivity for the house?
Hi , Thank you for getting back to me, I will discuss the internet issue with the new neighbours and see what was said, I don't believe we involved our solicitors on this issue, we just discussed with the seller if internet access was available, and was told "I get it " he lives at the end of the development and receives very slow BT internet, however the signal isn't strong enough further down the development to get any land line internet.
Do we have any influence with the forest owners over concerns about the trees being so close to the house, and if they blow down they would damage the roof and property, how would we stand with insurance on this???
If the trees are blown down and cause foreseeable harm to your property then you might have an action against the forest owner. However, if there has been no mismanagement of the trees and they are blown over causing damage it could be argued that it is either the developer or you who are to blame for building on/moving to land that was already at risk.
