Insurance Brokers and Insurers cannot tell you what levels of cover you require, but we can  provide a variety of options  including a combination of indemnity limits and the first amount of any claim that you will be responsible for i.e. the excess.  It is essentially your responsibility to take out adequate cover, although our advisers can go through your options over the phone and explain how you might want to calculate this cost. Many industry organisations and professional bodies will likely be able to offer you guidance as many will have minimum insurance requirements for authorisation or membership. Remember to review your customers contractual requirements, as these will often specify the limits of indemnity and the number of years they would expect you to arrange cover from the start date of contract.
