Your company
Working through your own limited company.
GreenBook engages contractors through their own UK limited company. An umbrella option is coming soon; until then you can join and build your profile, but companies can't engage you through an umbrella yet.
- What you write about yourself shows as self-declared
- Before an assignment starts, GreenBook checks your right to work, your company and your insurance
- Your profile shows each check and whether it's verified, never the documents

The Founding 500
We're inviting the first 500 UK renewable-energy contractors to build their GreenBook profiles as we build the network. Founding 500 members appear at the top of matching search results. Search filters still apply, and priority visibility doesn't guarantee work.
Free to join. An invitation, not a paid membership.
Join the Founding 500A few things worth knowing.
Is GreenBook free for contractors?
Yes. It's free to join and build your profile. GreenBook's fee is added to the rate the company pays; it's never taken from yours.
Does joining guarantee an assignment?
No. Your profile makes your skills and availability easy to find. Companies choose who to engage.
When am I paid?
Within 14 days of your timesheet being approved. If something is missing (your company's invoice, verified bank details or a satisfactory right to work check), the 14 days start when it arrives.
Do I need my own limited company?
For now, yes: GreenBook engages contractors through their own UK limited company. An umbrella option is coming soon.
Does everything need to be checked before I join?
No. You can join and fill in your profile straight away. The checks an assignment needs are done before it starts.
