About Our Outside IR35 MOD Contract Roles
What does a mod contractor do?
MOD contract work spans across the full range of professional and technical disciplines that support the UK's defence capability, including engineering, programme and project management, commercial and procurement, finance, digital and technology, intelligence analysis, logistics, and estate management. The MoD is one of the largest and most complex government departments, operating a capital programme that spans major platforms including the F-35 programme, Type 26 frigates, the nuclear deterrent, Ajax armoured vehicles, and a broad portfolio of digital and information technology programmes. Contractors are engaged both directly through MoD departments and agencies, and through the major defence primes and tier-one contractors including BAE Systems, Babcock, Leonardo, QinetiQ, and DSTL.
Working within the MoD as a contractor requires an understanding of the specific governance, acquisition, and delivery frameworks that govern defence programmes. Familiarity with the CADMID cycle for capability acquisition, DRACAS reporting, and the Defence Procurement Model is expected for programme management roles. Commercial contractors need knowledge of Defence Conditions and the specific procurement regulations that apply to defence contracts. The security environment in defence is more complex than most other sectors, with SC clearance expected as a standard requirement for most MoD contractor roles and DV clearance required for roles involving access to classified information. The combination of security clearance, sector knowledge, and relevant technical expertise creates a significant entry barrier that supports premium rates for contractors who can meet all three requirements.
What is the market like for mod contractors?
MoD contracting is a large, long-term, and relatively stable market underpinned by the UK's sustained defence investment programme. The government's commitment to meet and exceed the NATO 2% of GDP defence spending target, combined with the elevated threat environment in Europe following Russia's invasion of Ukraine, has increased MoD programme investment and contractor demand across engineering, technology, and programme management disciplines. The MoD's digital transformation programme, which includes significant investment in cloud infrastructure, cyber capability, and defence data platforms, is generating growing demand for technology contractors with appropriate security clearance. Rates for SC and DV-cleared contractors consistently command a premium above equivalent uncleared roles, reflecting the combination of clearance requirements and specialist defence sector knowledge.
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.
What mod roles are usually Outside IR35?
MOD contracts have a mixed IR35 profile. The Ministry of Defence has a long tradition of engaging specialist contractors, particularly in systems engineering, technical consultancy, and programme management. Outside IR35 opportunities exist where the engagement involves defined technical deliverables or advisory work. DE&S acquisition programmes and DSTL research contracts occasionally structure work on an outside IR35 basis. SC or DV security clearance is a prerequisite for virtually all MOD contracting, and the clearance requirement narrows the candidate pool significantly.
How much do mod contractors usually earn when working Outside IR35?
Contract rates for mod roles typically range from £400 to £750 per day, depending on the scope of the role, required expertise, and the delivery expectations of the engagement. Rates shown are for outside IR35 engagements and reflect the gross day rate paid to the contractor's limited company before any personal tax obligations.
