Monthly payment calendar

Please submit your approved timesheet to us by midnight on working day two for payment on the last working day of the month. You'll find the monthly deadlines and payment dates in the tables below.

If you are paid via an Umbrella Company, please check with them to confirm when you will receive payment (this is usually the next working day after the payment dates shown below).

Self bill

Hydrogen operates a Self Bill payment process for contractors. This means that you do not need to send an invoice with your timesheet or expense claim as we will produce an invoice on your behalf and email it to you.

Self Bill is fully HMRC compliant, helps to reduce payment delays and is a common practice within the recruitment industry (you may have contracted this way previously).

As part of the onboarding process, you will be asked to sign a Self Bill Agreement which may be included in your contract.

Please note that if you are paid via an Umbrella Company, we will be asking them to sign the Self Bill agreement as they send us the invoice.

If you have any questions, please email selfbill@hydrogengroup.com.
