It all depends what work you do, there are no regs to say you must have an analyser, however the regs and MI now state where you must check an appliance using an analyser, so if you do that work then it's obvious you must have access to an analyser, you don't have to own one, you can borrow or hire one, but the inspector isn't stupid, if you say you fit boilers and hire an analyser to comply with the new requirement to check it then he will want to see receipts, the bottom line is you say you work safely so you will know if you have ever done any work that should have required the use of an analyser, if you have only worked on cookers or standard efficiency boilers then visual and gas rate will suffice
