Service 1 icon

Limited Company Solutions

If you wish to work through your own limited company, then we can support you with advice on any insurances that you may need.

You will likely be the MD, and be responsible for any taxation, accounting and legal requirements of the company.  You may decide to appoint an accountant to help you with the running of the business.

Service 2 icon

Umbrella Companies

If you decide to work through a PAYE Umbrella Company you will be classed as an employee of the Umbrella Company.

The Umbrella Company will invoice JAM for the services you have provided.  You will be paid a salary (with tax and NI reductions made) minus a fee for using the Umbrella Company. You can normally claim for certain types of expenses relating to the contract.

We have an extensive approved list of umbrella suppliers that we can work with.

Service 3 icon

PAYE Solutions

PAYE is the simplest payroll solution we offer. It's very similar to umbrella companies as you will become an employee/member of our client's team and receive a fixed rate of salary. This will be paid on a monthly basis, as agreed with JAM.

Service 2 icon

Consultancy Services

You set out the project scope and delivery requirments. We manage the strategic contracting and delivery of consultancy services. We offer you full control across all your project and consultancy spend, which is outcome focussed.

Frequently asked questions

Which company documents should I send?

You need to provide us with your certificate of incorporation, bank statement, VAT certificate (if VAT registered) and proof of Professional Indemnity and Public Liability Insurance. We may also ask for additional details like ID, National Insurance number and other documentation if requested by the client.

If you go through an umbrella company you will only need to send passport, National Insurance number and referee contact details. Your umbrella company will send across their company documents.

Which Umbrella firm should I use?

The umbrella market has many great suppliers, it also has a few less scrupulous ones. Because we are liable if we facilitate tax evasion, we have put together an approved list of umbrella companies, who are accredited.

When should I submit timesheets and when will I be paid?

Please submit your timesheet at the end of each working week or each working month depending on your agreed timesheet frequency. Ensure this is completed before the end of the following Monday in order not to miss the payment run.

Provided that your approved timesheet reaches us in time, your company will receive payment by end of business on Friday of the same week.

Remember, payment is in arrears.

Why do I need insurance

Many clients will require this before they allow you onto site. This is because you or your limited company (depending on how you are working) is legally responsible for your actions. Whilst we have never known a client to sue a contractor, should you be responsible for an issue causing significant damage or harm you could be legally responsible. Insurance provides you with peace of mind.

I can't see my assignment on InTime

Your assignment should appear once you begin working on site. If you are yet to start, please check back on commencement. If you are already working and you cannot see your assignment, please contact JAM.

Can I claim expenses?

You should agree any recoverable expenses in advance. We will process any expenses once they are approved by the client.
