You should also understand basic firewalls, authentication, access controls, network monitoring and troubleshooting. Later, you can add cloud networking, automation and more advanced security knowledge.

Do You Need a Degree?

A degree is one possible route, but it is not essential for everyone. The UK National Careers Service lists university, college, apprenticeships and working towards the role as possible routes into network engineering.

Relevant university subjects include network engineering, computer science, electronic engineering, network security and software engineering. Related subjects such as maths, physics and electrical engineering can also be useful.

For network engineers, the National Careers Service currently lists salaries of about £25,500 for starters and up to £52,000 for experienced professionals. Actual pay varies by employer, location, experience, specialism and responsibilities.

Network Engineering Apprenticeships in the UK

Apprenticeships can provide a combination of paid employment and structured training. The National Careers Service lists routes including Hardware, Network and Infrastructure Foundation Apprenticeships, Network Cable Installer Level 3 Advanced Apprenticeships, Network Engineer Level 4 Higher Apprenticeships and the Digital and Technology Solutions Professional Level 6 Degree Apprenticeship with a networking option.

The current Skills England information also lists a Hardware, Network and Infrastructure Foundation Apprenticeship at Level 2, approved for delivery from April 2025. Apprenticeship standards can change, so check the current official listing before applying.

Can You Start Network Engineering With No Experience?

Yes. A practical route is to build networking knowledge while applying for entry-level IT roles that give you exposure to infrastructure.

1. Learn the networking basics

Understand how devices communicate, how IP addresses work and what routers, switches, firewalls and access points do.

2. Practise in a home lab

Use virtual machines, networking simulators or affordable equipment to practise configurations and troubleshooting. Keep notes about what you built and the problems you solved.

3. Build Linux and Windows knowledge

Network engineers often work alongside operating systems and servers, so basic administration skills can make your networking knowledge more useful.

4. Learn troubleshooting

Practise working through problems step by step. Check physical connections, configuration, addressing, services and logs rather than guessing at the answer.

5. Consider an industry certification

Industry-recognised certifications can provide structured study and demonstrate knowledge. The right certification depends on your target role and employer requirements, so check job adverts before spending money on exams.

How to Build a Network Engineering Portfolio

A portfolio can be useful even when you have no professional network engineering experience. You could document a small virtual network, a home lab, a subnetting exercise, a firewall configuration or a troubleshooting project.

For each project, explain the goal, network design, tools used, configuration choices and problems you solved. Screenshots and simple diagrams can make the project easier to understand.

How to Find Your First Network Engineering Job

Search for roles such as network technician, IT support technician, network support technician, junior network engineer, infrastructure technician and network administrator.

Do not search only for jobs with the exact title “network engineer”. Some employers use different titles for entry-level infrastructure roles that can provide relevant experience.

How to Write a Network Engineering CV

Keep your CV focused on practical evidence. Include networking knowledge, technical projects, certifications, education, work experience and relevant IT skills.

Instead of simply listing technologies, explain what you used them for. For example, describe a network lab you configured, a connectivity problem you investigated or a monitoring project you completed.

Preparing for a Network Engineering Interview

Interview questions may cover networking fundamentals, troubleshooting, security and your previous technical work.

Be ready to explain concepts such as IP addressing, DNS, DHCP, routing, switching, VLANs and firewalls in simple terms. You may also be given a technical problem and asked how you would investigate it.

Network Engineering and Cybersecurity

Networking and cybersecurity overlap heavily. Secure network design, firewalls, access controls, monitoring and incident response all depend on a good understanding of how networks operate.

If security interests you, network engineering can provide useful technical foundations for moving into areas such as network security or broader cybersecurity roles.

Network Engineering and Cloud Computing

Modern infrastructure often combines traditional networks with cloud platforms. Understanding routing, addressing, security and connectivity can therefore help if you later move towards cloud networking or infrastructure engineering.

This also makes network engineering a useful complement to skills in cloud computing, cybersecurity and DevOps.

Career Progression in Network Engineering

With experience, network professionals can move into senior engineering, network management, infrastructure architecture, cloud networking or network security.

The National Careers Service also identifies progression into network management, business analysis, technical architecture, data analysis and software development, depending on your interests and skills.

Is Network Engineering Right for You?

Network engineering may suit you if you enjoy solving technical problems, understanding how systems connect and working through faults logically. Some roles involve on-call work, client sites or responding to urgent incidents, so the working environment can vary between employers.

Try practical networking exercises or an entry-level IT role before committing to a long training programme. This can help you understand whether the work suits your interests.

Final Thoughts

There is no single route into network engineering in the UK. University, college courses, apprenticeships and entry-level IT roles can all help you build towards the profession.

Start with networking fundamentals, practise troubleshooting, build hands-on projects and understand how networks connect with security and cloud infrastructure. Over time, these skills can support progression into specialist and senior technology roles.
