Thank you for taking the time to reply guys. Quite a bit of info to think about. I think upon reflection a bigger van might be unnecessary. A 500 litre sounds good to me. I currently have a combo and is running fine (8 year old) so it might be an idea to experiment so to speak with a non top of the range system (just a decent pump/hose reel etc) and once used to working with a hose reel perhaps upgrade to a new van then.I would rather get someone to fit it all for me as I am completely clueless from a DIY point of view.I have a vauxhall combo Lwb I have a 400 grippatank system in the back with internal and external hose ports meaning I can have the hose real fixed in or out as I choose.With a 1 ton payload its a great size van and could easily hold a 500. On the odd job I can take extra barrels if needed but all my work is fairly close.The van is up for sale shortly with no vat and located in Hertfordshire if your looking for a second hand van and system drop me an email or call and I can send you more info.info@cghwindowcleaning.co.ukAny suggestions on who can fit in the Suffolk area? Also how much tax would you actually save if you did go all in? I was told it’s only 18% a year as a sole trader and you keep claiming the vehicle until it’s valieless. Also not being VAT registered there is no point buying a commercial van with vat as can’t claim it back.Thank you Darren for offer of coming up. Where in norfolk are you? I am Ipswich Suffolk based.So much to think about......cheers again guys
