Thanks for the replies. The pressure washer is a honda petrol. It has a red hose reel and pressure hose. The window clenaing equipment in the back is a 400 litre tank, reel, gardiners brush etc.
Also my insurance company have refused to pay out so that's about 10 grand down the drain.
It can't be as open and shut case as that surely. Like it's been said, you were a few steps away from the car, parked on a drive way. They came onto private property and took it.
Just like if you don't lock your front door, and someone walks in, takes your keys and drives off with your motor. Your still insured. The keys were in your house, and they can't force you to lock your front door all the time.
Get legal advice ASAP as the insurance company will just try fob you off.
