How to Become a Telecommunications Engineer in the UK (2026 Guide)
Overview
Telecommunications engineers install, maintain, and repair the networks that carry phone calls, broadband internet, and data across the UK. With the government's target for nationwide gigabit broadband coverage, the massive 5G rollout, and the switch-off of the old copper PSTN network by 2027, telecoms engineers are in huge demand. The sector needs tens of thousands of additional engineers over the next few years. Whether it's laying fibre optic cables, installing mobile masts, or configuring broadband equipment in exchanges, this is a trade with exceptional job security and growing pay.

Step-by-Step Career Path
Get Your Basic Qualifications
GCSEs in Maths, English, and IT or Science at Grade 4 (C) or above. A-levels or equivalent in IT, engineering, or physics are helpful but not essential. A full UK driving licence is required as you'll travel between sites daily.
Apply for an Apprenticeship or Trainee Role
Major employers include Openreach (BT's network arm), Virgin Media O2, CityFibre, and contractors like Kelly Communications, Morrison Telecom Services, and Telent. Openreach alone recruits over 3,000 engineers per year. Apprenticeships last 18-24 months and earn £18,000-£22,000 to start.
Complete Fibre Optic and Copper Training
You'll learn to install, splice, and test fibre optic cables, maintain copper networks (until PSTN switch-off), configure routers and ONTs (Optical Network Terminals), and troubleshoot faults. Fibre splicing — using a fusion splicer to join glass fibres thinner than a human hair — is the core modern skill.
Get Industry Certifications
Key qualifications include the EUSR (Energy & Utility Skills Register) card for street works, NRSWA qualification for working in roads, and specific manufacturer certifications (e.g., Huawei, Nokia, Ericsson for mobile infrastructure). Many employers also require IPAF for working at height on masts and poles.
Specialise in a Telecoms Discipline
Choose from: fibre to the premises (FTTP) installation, mobile network (4G/5G) installation and maintenance, exchange and core network equipment, or enterprise networking. Each specialisation has different earning potential and working environments.
Progress to Senior and Specialist Roles
Experienced engineers can become team leaders, network designers, or specialist fibre engineers. Senior roles in 5G infrastructure, network planning, or project management can pay £45,000-£65,000. Some engineers start their own telecoms contracting businesses.
Qualifications Needed
- ✓NVQ Level 2/3 in Telecommunications
- ✓EUSR (Energy & Utility Skills Register) Card
- ✓NRSWA Street Works Qualification
- ✓Fibre Optic Splicing Certification
- ✓IPAF Licence (for pole and mast work)
- ✓Full UK Driving Licence (essential)
- ✓Manufacturer certifications (Huawei, Nokia, Ericsson — for mobile network work)
- ✓CSCS Card (for construction site access)
Pros & Cons
✅ Pros
- Massive demand — the UK needs tens of thousands more telecoms engineers
- Excellent job security with the fibre and 5G rollouts
- Good salary with strong progression potential
- Company vehicle and tools usually provided
- Varied work — no two days are the same
- Essential infrastructure work with a sense of purpose
❌ Cons
- Outdoor work in all weather conditions
- Working in confined spaces (manholes, ducts, cabinets)
- Some work at height on poles and masts
- Customer-facing — dealing with frustrated broadband customers
- Technology changes rapidly — continuous learning required
- Can involve unsocial hours for network maintenance windows
Frequently Asked Questions
How much do telecoms engineers earn?▼
Trainee engineers earn £20,000-£25,000. Qualified engineers earn £28,000-£38,000. Senior and specialist engineers (fibre planning, 5G) earn £38,000-£55,000+. Openreach engineers typically earn £28,000-£36,000 plus overtime and a company van. Self-employed fibre splicers can charge £200-£350 per day.
What is the PSTN switch-off?▼
The UK's old copper telephone network (PSTN — Public Switched Telephone Network) is being switched off by 2027. All phone and broadband services will move to fibre or digital alternatives. This is creating huge demand for engineers to install fibre and decommission copper infrastructure.
Is telecoms engineering a good career in 2026?▼
One of the best. The UK government wants nationwide gigabit broadband, the 5G rollout is ongoing, and the PSTN switch-off requires massive infrastructure work. The industry estimates it needs 50,000+ additional engineers. Job security and pay are both strong and improving.
Do I need a degree?▼
No degree is required for most field engineer roles. Apprenticeships and on-the-job training are the standard route. However, network design, planning, and senior technical roles may benefit from or require a degree in telecommunications, electrical engineering, or IT networking.
What is fibre splicing?▼
Fibre splicing is the process of joining two optical fibres together using a fusion splicer. The machine precisely aligns the glass fibres (thinner than a human hair) and fuses them with an electric arc. A good splice has minimal signal loss (less than 0.1 dB). It's the core skill for modern telecoms engineers.
