Just noticed that nobody had responded to your question.
As a ltd company you should have liability cover so if you damage a clients equipment or injure someone on a job you are covered.
There is another insurance which covers you as the employer in the event of you injuring yourself/employee. This one may not apply to you as in the event of a major payout by the insurance company they would possibly look to reclaim some of the money and would end up suing you as the company director for the money they have just paid you, stupid really but there you go.
For public and Private liability cover you would expect to pay in the region of £1050 a year. For the essential cover which I think is the Public liability it is around £800 a year.
