thats ok vg butt in whenever you like,
one of the guys who bought the lance said he had to buy another fitting or hose to connect the lance to his pressure washer, i know jeff bought the lance recently and a pressure washer from b&q so wondered if he had the same problem
If you buy a cheap pressure washer, the hose may not fit?
I had a pro pressure washer before it blew up

and the hose from that fitted the lance and my new pressure washer.
The lance does come with a couple of additional fitting that may well help you fit your exsisting hose. HTH
I bought my pressure washer from Toolstation in the end and not B&Q
