Professional Passport working to raise the standards
See our list of audited contractor umbrella and accountancy service providers

Professional Passport is a completely independent organisation and as such is able to accurately assess any offerings without any commercial pressures.

We would like to make it clear that we do not receive any commissions from providers where you select to use their services.

Professional Passport does not favour any particular operating structure over another and believes that contractors should choose the right operating structure for them based on their personal circumstances.

Professional Passport only audits Umbrella, CIS and Accountancy Service solutions for contractors working in the UK. Some providers offer additional solutions including services for contractors working overseas, these services are not currently audited by Professional Passport.

Contractors can take reassurance from the fact that Professional Passport can also be liable under the debt transfer rules. This fact ensures that we always operate to the highest standard and will only deal with providers that we believe to be compliant; and just to reiterate we do not take any commissions from providers where you select to use their services.


As a market leader, Sterling hold preferred supplier status with major UK recruitment agencies, offering services enabling them to work more efficiently and cost effectively and also ensuring contractors benefit from bespoke streamlined processes whilst maximising their income. The service we provide always has been and always will be of paramount importance.

We are now in our fifteenth year of trading and can confidently say that we have always remained compliant and have adapted our services over the years as and when required due to legislation changes whilst keeping our contractors satisfied. We offer a comprehensive insurance package including Employers, Public, Professional Indemnity, Offshore and Personal Accident at work insurance.

Based on your circumstances we have three routes to offer contractors, our employed route; Sterling Umbrella, our self-employed route for contractors; Sterling CIS, and our self-employed route for all other industries; Sterling Techserv.

In a recent survey 99% of our contractors stated that they were happy with the service they receive from Sterling. So why not become another happy contractor and join the thousands of contractors already enjoying the benefits of Sterling.
