Monthly payment calendar

Any remaining monthly timesheets for previous months that miss the monthly payment deadline.

InTime is our online portal for submitting timesheets and expenses. Our Contractor Care team will confirm if you will need to use InTime.

InTime is simple and easy to use and can be accessed from smartphones and tablets. As a contractor or timesheet approver, you will receive a unique login to quickly submit or approve time and expense claims as well as being able to view timesheet and payment statuses.

If you have not yet received your InTime login details please contractor our Contractor Care Team at intime@hydrogengroup.com.

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.
