This is a question we often get asked, I am a contractor am I required to set up a pension scheme?
It is now a legal requirement for all employees to have a workplace pension scheme. Providing you are the Director of your Limited Company, and have no employees, you should not be deemed an employer for the purpose of self employment and thus not have any requirements for a workplace pension. You should confirm this with the pension regulator to ensure they agree.
If this changes and you employ staff in the future, you will need to consider whether you are required to provide a workplace pension for them.
You may want to consider the National Employement Savings Trust (NEST) as they will accept all employers. NEST levies an annual management charge of 0.3% of the members pension pot and a 1.8% charge on all contributions made.
