Contractor Services by Omnia

Contractor engagement and compliance

Through Omnia Outsourcing we can deliver a range of services to engage your temporary workforce and contractors ensuring compliance with HMRC and government regulations.

Contractor Services

Umbrella PAYE employment

Our employed umbrella option is a fully compliant way of taking away the administrative burden and many of the risks associated with employing a temporary workforce directly.

CIS Sub-contractor engagement

We are a gross status CIS contractor and can engage self employed CIS sub-contractors directly ensuring that all HMRC compliance matters are taken care of.

Self Employed Sub-contractor engagement

Legitimately self employed contractors are able to engage directly with Omnia Outsourcing to provide their services through an intermediary who will ensure that all compliance checks and self bill invoices are taken care of.

Limited Company (PSC) engagement

Omnia can engage and assist PSCs (Personal Service Companys) who operate either ‘inside’ or ‘outside’ of the IR35 rules ensuring compliance and risk management at all levels.

Outsourced PAYE

A cost effective, transparent and simple option that allows agencies or contractors to continue to benefit from a fully outsourced solution.

PEO/Joint Employment

Omnia can offer ‘Joint Employment’ to businesses that require a compliant option that gives them more control and whilst still relying on a professional partner to care of all admin, HR and payroll matters. The Joint Employment model is increasing in popularity and offers increased cashflow over Umbrella options.
