Pesting liability insurance.

Never heard of that. I’ve heard of insurance and legal for Concealed Carry. There is insurance for just about everything though so I am sure you might find something under farming and pesting. Common in the UK huh? Crazy how different our countries are. 


Best type of insurance is a safe backdrop and clear surroundings where safe target and pesting can take place. If buildings or people are in danger of being hit, don’t shoot. 
 
If you want to really protect yourself, insurance won't be as good as getting the homeowner to sign a waiver. If thats possible and won't scare away the owner that is. Insurance companies make money by denying coverage or not paying out enough to third party claimants and you could end up in court named as a defendant all the same.

If you get the homeowner to sign a waiver to hold you harmless, then you only have to worry about claims by neighbors if you impact their properties. If that ends up happening anyway, your activities may be covered under your homeowners insurance or the homeowners insurance of the property where you are shooting.

At the very least get written permission from the homeowner. 

PS not trying to poo poo you- I've shot places without doing any of what I just suggested haha 



EDIT: if you really want to know about insurance for your particular activities, call your homeowner insurance broker [NOT your homeowners insurance] and ask him/her casually "for a friend" if there is such a thing.
 
I know of companies that offer it for posting businesses that shoot for a job. I am one of them. I don't know if they offer coverage for non-licensed individuals. Snow and Bell Inc out of Florida is one of the best for coverage but it may be more than you want to spend.

I think a lot of these guys are on the right track with getting a hold harmless agreement signed before hand. 
 
Aaron Cantrell has a couple of interesting videos on this, sorta. Not insurance specifically, but on pre-checking all buildings you might be shooting around to check for previous shooting damage (wacky kids, careless owners, even purposeful holes put in that could be interpreted as pellet/bullet damage). In one, he walks through a good number of buildingsf. I imagine it's not enough that YOU know how many holes are around and that you didn't cause them, but that the OWNER knows and signs off after going on a tour with you.

Will every owner want to go to the trouble? Dunno. But it sounds like a great way to increase the peace between you and decrease the liability. I'd still get a waiver saying you mutually inspected the property,and possibly even get it on film.

Sorry, but I've worked for and with lawyers most of my life. I wish I could say different, but I know how nuts people can be over such things. You could be asked to pay for a new roof etc by a particularly evil-minded or foolish person. The law can be bent to dopey purposes pretty easily ... and commonly.
