If you are self employed/sole trader and are not VAT registered do not use! Their sales people quote EX VAT and there is no cooling off period so once you sign that contract thats it. Plus all the discounts that they hard sell you over the phone end in 17 months (they don't mention that). If you don't thoroughly read the contract you do not notice this as there is so much on it while a sales person is rushing you to sign.
