Yes, I would agree with my colleagues on this matter. An accounting audit isn't necessary to satisfy the law unless your turnover is quite high (in relative cleaning terms that is), but you might need it to satisfy a potential lender. Most cleaners cover their risk by taking out insurance for Public Liability and Treatment Risk, hence the limited liability issue is probably not that relevant in this business. However there can be tax advantages in forming a Ltd Co., but Mr. Brown makes these less attractive every year and HMR&C can even look at dividend drawings to see if these are being used to create unreasonable tax advantages. Despite this, a Ltd Co. does get the benefit of a protected name, but beware, it can also make you look like a rather big organisation, which might put off a few people who want to support a small venture, or assume that you're expensive ! So:
1. get a bit of free advice from, say, The Business Link
2. assess the risks
3. go for it !
Hope all this helps.
