An umbrella company is a type of employment agency that acts as an employer for individuals who work on a contract or freelance basis. These individuals, known as "umbrella employees," provide services to clients through the umbrella company, rather than working directly for the clients themselves.

The umbrella company acts as a middleman between the individual and the client, handling the administrative tasks associated with employment such as payroll, taxes and other compliance related matters. They typically charge a fee for their services and make deductions for taxes and national insurance contributions.

Umbrella employees are considered employees of the umbrella company, which means that they are entitled to the same rights and benefits as any other employee, such as statutory sick pay, annual leave, and protection under employment laws. This type of arrangement is particularly useful for individuals who work in industries that typically rely on a short-term contract or freelance work, such as construction, engineering, or IT. It may be considered as a simpler and more convenient way to manage the administrative and compliance aspect of their work. However, it's important to note that the contractor should ensure that the umbrella company is compliant with the laws, regulations and taxes of the jurisdiction and also the cost should be carefully considered as the fees can be high.
