Network engineers design, implement and maintain the routing, switching, firewall and increasingly cloud networking infrastructure that keeps organisations connected. Most work as permanent employees, progressing through Cisco CCNA/CCNP/CCIE or vendor-neutral certifications, though many experienced network engineers move into day-rate contracting. This guide shows exactly what network engineers take home after income tax and National Insurance for the 2026/27 tax year.
Figures are indicative market rates; actual pay varies by employer, region, experience and sector.
| Role | Career Stage | Salary Range | Notes |

| Network Engineer | 2--5 years | £34,000--£45,000 | CCNP-track; routing, switching, firewall administration |
| Senior Network Engineer | 5--8 years | £46,000--£62,000 | Design and lead network changes; may hold CCNP/CCIE |
| Principal Network Engineer/Architect | 8+ years | £65,000--£90,000+ | Network architecture strategy across the organisation |
These scenarios illustrate take-home pay at different career stages using 2026/27 England tax rates (personal allowance £12,570), for a standard employed PAYE role.

Cisco Certified Network Associate (CCNA) is typically the entry point, CCNP demonstrates professional-level competence and significantly increases salary, while the elite CCIE certification, held by a small proportion of engineers, commands the highest premium in the field.
Engineers with cloud networking skills (AWS/Azure/GCP VPCs, SD-WAN, cloud security groups) alongside traditional on-premises routing and switching are increasingly in higher demand and better paid than engineers with only legacy on-premises skills.
Financial services and telecoms network engineers, where network uptime and security have direct commercial or regulatory consequences, typically pay a premium over general corporate IT network roles. Managed service provider (MSP) roles often pay less but offer broader exposure across many client networks.
Experienced network engineers, particularly those with CCIE or specialist security/SD-WAN skills, can work as day-rate contractors on infrastructure projects, typically through a limited company. This can significantly increase gross earnings, but requires managing IR35 status and forgoing paid holiday, sick pay and employer pension contributions.
