Can anyone tell me if there are any decent policies protecting income due to sickess or accidents which can be taken out by agency drivers?
I’ve been looking on the usual price comparison sites but they all seem to state that you have to be in permenant employment.
Cheers. 
You won’t be able to get Income Protection Insurance (IPI) if you work for an agency. If your work is casual, temporary or seasonal in nature or unemployment is a regular feature of your particular job, then Insurers will not entertain you. There are quite alot of other exclusions for IPI Policies, but the above it the most important to insurance companies.
