Weekly payment calendar

Timesheets are paid within 30 days of receipt providing they have been submitted in line with the weekly timesheet payroll deadline. In practice this means:

  • Approved timesheets received by 5pm on Monday will be paid 4 weeks later on Monday
  • Approved timesheets received after 5pm on Monday are processed the following week and paid 4 weeks later on Monday

Our Contractor Care Team will let you know how to submit your Timesheet and Expense Claims. You may be required to complete a Client-specific timesheet or use their online timesheet portal. Alternatively, we may ask you to use our InTime online portal (further details below) or complete a Hydrogen Paper Timesheet which you can download here:

InTime

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.

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.
