Core ACS Umbrella

Working as an umbrella employee is simple to set up and easy to use. Workers can enjoy the flexibility of contracting, whilst enjoying the statutory rights of any UK employee, such as Statutory Sick Pay and Maternity/Paternity Pay.

Unlike working as a Limited company contractor or as a CIS operative, you simply work and get paid and Core will do the rest.
