please recommend a fix rate umbrella company for short term contract

The vast majority of umbrella companies have a fixed margin and all should have professional indemnity insurance included without a cost to you

ideally low fee with standard insurance cover. thank you in advance

Just to clarify, what do you mean by fixed rate? A set percentage of the rate or a set amount in £ per payroll run?

I'd imagine all Umbrellas already have professional insurances in place so you could confirm that was part of the engagement process if you're shopping around.
