🛡 Responsible Recruitment & JSL Compliance Notice
In response to the UK’s shifting labour enforcement landscape and the introduction of Joint & Several Liability (JSL) in April 2026, our agency operates to the highest possible compliance standards to protect our clients from unbudgeted tax liabilities.
- Eliminating the “Connected” Risk: Under JSL rules, a client becomes directly liable for unpaid taxes if their agency is financially connected to the umbrella company used. We have no financial or structural ties to any umbrella provider, ensuring an independent and compliant supply chain.
- High-Risk Sector Protection: HMRC has identified Construction as a primary target for enforcement. We mitigate this risk by providing full, real-time audit trails for every worker.
- Real-Time Auditing (SafeRec): We utilize SafeRec to provide monthly, independent audits of all payslips. This ensures that PAYE and NICs are calculated correctly and that “due diligence” is backed by actual data.
- Defence Against Liability: The new legislation states that “having undertaken due diligence” is not a valid defence against liability. Our systems are designed to provide the proven compliance that HMRC demands to protect your business.
- Single-Supplier Transparency: We operate a transparent, non-subcontracted supply chain, ensuring that every worker on your site is fully traceable.
