Ask an Property Solicitor. Get an Answer ASAP.
Hello, welcome to the website. My name isXXXXX can assist you with this.
If the light has come through the windows for 20 years (absent an express right of light in your property deeds or some other document) then you might have an actionable cause of action here.
It does require the light to have diminished by a noticeable amount, not just a trifling amount, it has to actually interfere with your enjoyment of the property. If you have these things, then you should have a cause of action.
Rights of light though, I will flag now, can be incredibly difficult when it comes to legal argument etc. surrounding them.
The kitchen and patio door have always received full sunlight through them however I now receive no sunlight through either, this is now due to the combination of the conservatory (which was only built 9cm away from the boundary line) and the now the six foot fence. Three quarters of my garden(from the back of the house now receives no sunlight at all).
Then you may have something to base a cause of action on here.
I would recommend you get photos of the issue, the windows etc., the fence and take them to a solicitor and give him.her a full background. Then get a letter before action written by him/her. Hopefully, to avoid court action, the fence would be removed.
Thank you, XXXXX XXXXX do that and again thank you for your advice as like last night it has been invaluable to me.
