$5M Public Liability included at no extra price
Purpose
For your own protection you should have a minimum level of Professional Indemnity(PI) insurance. In the event that the services you provide for a client lead to a claim against that client they will generally look at claiming against the contractor. PI insurance will protect you in the event that this occurs.
In addition, the majority of jobs you are contracted to do, and most tenders you respond to call for proof that you have a minimum level of PI and Public Liability cover.... You will generally not be considered for a job without it !
