Party wall Issue - Please help!

Other

I am a private landlord, I have just been to inspect my property and have a problem.

The house next door (adjoined as its a terrace) has been derelict for many years.

Approx 2 yrs ago the party garden wall was knocked down to allow access for the house to be renovated including a rear extension.

I could not locate the owner and after 6 months of no work on the propery I eventually paid for a fence to be errected as the view from the rear window and back door was unsightly.

Today, my current tenants informed me that 5 months ago, the builders removed the fence and started to build the extension.

Scaffold has been on my Land for 5 months without permission. The scaffold is ouside the back door and has be walked under to access the rear garden / clothes line.

The tenants who are now negotiating a new contract would like a discount due to the inconvienince of the scaffold, noise and lack of light at the rear.

The house is developing very slowly, the tenants estimate the house is only worked on average twice a week. At this rate I can expect the scaffold / noise mess for many months if not years.

If I were to re-let I would have serious issues in getting any tenants with children or any that wanted to use the garden.

Question 1. Can the builder errect scaffold on my property without permission?

Question 2. Can I do anything to get it removed?

Question 3. If my rental revenue is or ability to let is impacted is the neighbour liable?

Help appreciated.

Regards
