About Our Outside IR35 Contract Roles in Cardiff
What is the contracting market like in Cardiff?
Devolved government makes Cardiff the administrative centre of Wales and a consistent source of programme management, policy, and digital delivery contracts. Insurance and financial services employers, several of whom have established significant operational centres in the city, provide a steady flow of IT, data, and change roles. An emerging technology sector around the city centre and Cardiff Gate business park has added software development and cloud engineering to the local mix, though volumes remain modest compared to larger English cities. The Welsh Government's investment in digital capability is a distinctive feature of the Cardiff market, creating opportunities in govtech and public service transformation that are structured and funded differently from equivalent programmes in England.
What does Outside IR35 mean?
IR35 is UK tax legislation that determines whether a contractor is genuinely self-employed or working in a manner that resembles employment. When a contract is classified as outside IR35, the engagement is treated as a business-to-business arrangement. The contractor operates through their own limited company, invoices for services, and manages their own tax affairs including corporation tax, self-assessment, and VAT where applicable.
Outside IR35 engagements are assessed against three key factors: the degree of control the client exercises over how the work is delivered, whether the contractor has a genuine right to provide a substitute, and whether there is a mutuality of obligation between the parties. Contracts that demonstrate contractor autonomy, project-based delivery, and the absence of ongoing employment obligations are more likely to sit outside IR35. Since April 2021, responsibility for making this determination sits with the end client for medium and large private sector organisations.
On QualityContracts.co.uk, approximately 28% of roles with a stated IR35 status are classified as outside IR35. The proportion varies by sector and role type, with some disciplines seeing a significantly higher or lower share of outside IR35 opportunities. Each listing on this page displays its IR35 status where provided by the hiring organisation.
