I am set up as a Limited Company but to date have not actually used it. I am now engaging in contrcat work and need to know what I need in terms of insurance. I am sole entity in company, no employees.

Turtle, the answer depends entirely on what activities your company will be carrying out: can you cause harm or financial loss to anyone? How likely? How much? What will your customers demand? If you are undertaking hands-on site activities you need to consider dropping the proverbial spanner in the works, or on somebody's head: Public liability insurance. If you are offering advice that could lead to financial loss or others making costly errors: Professional Indemnity Insurance. Motor insurance if driving is a requirement. Travel insurance may be appropriate for some journeys. Personal income protection/illness/life insurance may all be appropriate depending on your circumstances. HOWEVER, as this is a safety & health site, not a financial/insurance forum it may be better to seek advice from somebody more competent in this subject: an insurance broker who specialises in small business in your field of activity.

U need to take advice and quickly as the inland rev can be very hard NB: You are not a sole trader if you are operating within your limited company
