Normal house insurance would not cover this sort of display.
You would have to take out a separate policy and have it installed professionally. People have been caught out in the past when bad weather has damaged their house only to find the insurance either won't pay up (because you have made alterations to the structure), or will pay out a reduced sum.
If in any doubt give them a ring. Oh, and if its council property they can force you to remove them immediately.
Sorry to be the bearer of bad news but its your responsibility.
