About Our Outside IR35 Network Engineer Contract Roles
What does a network engineer contractor do?
Organisations bring in Network Engineer contractors to implement, maintain, troubleshoot, and optimise the network infrastructure that underpins an organisation's connectivity, whether within data centres, campus environments, branch office networks, or cloud-hosted environments. The work spans configuring switches, routers, firewalls, and load balancers; troubleshooting network performance and connectivity issues; implementing network changes as part of technology projects; managing network monitoring and alerting; and supporting the documentation and operational maintenance of the network estate. Network Engineers are brought in to provide additional capacity during network projects, to cover vacancies within network operations teams, or to provide specialist expertise in particular networking technologies or vendor platforms.
The technical skills expected of Network Engineer contractors depend on the environment and the nature of the engagement. Strong knowledge of TCP/IP networking fundamentals, including routing protocols such as OSPF and BGP, VLAN design, and switching architecture, is expected as a baseline. Hands-on experience with the relevant vendor platforms, most commonly Cisco for enterprise environments, alongside Juniper, Fortinet, Palo Alto, or Aruba depending on the specific environment, is the primary practical requirement. For cloud-focused roles, knowledge of AWS, Azure, or GCP networking services including VPCs, Transit Gateways, and ExpressRoute is increasingly expected. Network security skills, including firewall policy management, IDS/IPS configuration, and network access control, are widely valued. Cisco CCNA or CCNP certification is well regarded and frequently listed as a preferred or required qualification.
What is the market like for network engineer contractors?
Network Engineer contracting is a steadily active and mid-volume market, driven by the ongoing need to maintain, upgrade, and extend network infrastructure across organisations of all sizes. The migration of enterprise network infrastructure to SD-WAN and cloud-based networking models is generating project-based network engineer contract demand as organisations replace legacy MPLS and campus switching infrastructure. The growth of hybrid working has created additional demand for network engineers who can support secure remote access infrastructure and manage the performance of distributed network environments. Rates are solid across the network engineering market, with specialists in cloud networking, SD-WAN, and network security consistently commanding rates above the generalist network engineer market.
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 network engineer roles are usually Outside IR35?
Network engineering has a relatively low outside IR35 rate at around 20% of contracts with a stated status. The operational and support-heavy nature of most network engineering work explains this. Contractors who focus on project-based activities, infrastructure deployments, data centre migrations, or new site builds with defined completion criteria, are better positioned for outside IR35 engagements. Managed service providers, telecoms operators, and specialist integrators offer the majority of this work. Design-level certifications in Cisco or Juniper help.
How much do network engineer contractors usually earn when working Outside IR35?
Contract rates for network engineer 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.
