I've sorted it now thanks guys. My existing broker found me one similarly priced with no height restriction, fascias/guttering included and my tool cover although with a £350 per item limt. He said my super max 44 could be bought in sections if need be to get round this.
It still doesn't cover damage to signs or items being cleaned but he said I'd be looking at about £600 if I wanted that which is way above my budget.
It's not perfect by any means, I know, but it will have to do for the forseeable future.
