Employment status in the UK is determined by the reality of the working relationship, not the label on the contract. The three key tests are personal service and substitution, control, and mutuality of obligation — and the written agreement should accurately reflect all three.
Signatures captured on SigningVault are Simple Electronic Signatures under the Electronic Communications Act 2000 and the UK eIDAS Regulation. Every signature is stored with the signer's name, email, IP address and a UTC timestamp in a tamper-evident audit trail, so the agreement stands up if it is ever challenged.
FAQ
No, but it matters. HMRC and the tribunals look at the actual working practices, and a contract that matches those practices is strong supporting evidence.
For medium and large private sector clients and all public sector clients, the end client makes the determination. Small companies leave the decision with the contractor's own company.
No. It is influential but must be genuine and unfettered in practice, alongside control and lack of mutuality.
Public liability is common for site work; professional indemnity for advisory or technical work. The template sets minimum cover levels.
