Electrician vs Gas Engineer: Which Career?

Electricians and gas engineers are both essential trades with strong demand across the UK. However, the long-term outlook for each profession is markedly different. The transition to electric heating, the growth of renewable energy, and the planned phase-out of gas boilers are reshaping the landscape.

This guide provides an honest comparison of the two careers — what each involves today, what the future holds, and which might be the better choice depending on your circumstances. You may also find our electrician vs plumber comparison useful.

Training and Qualifications

Both trades require formal qualifications, but the regulatory framework differs significantly.

Electrician qualifications

✓City & Guilds 2365 Level 2 and Level 3 Diplomas
✓18th Edition Wiring Regulations (2382)
✓Inspection and Testing (2391)
✓NVQ Level 3 (2357) for ECS Gold Card
✓Optional specialisms: EV charging, solar PV, data centres
✓Competent person scheme registration (NICEIC, NAPIT)

Gas engineer qualifications

✓ACS (Accredited Certification Scheme) gas safety assessments
✓CCN1 core gas safety — mandatory for all gas work
✓Appliance-specific modules: boilers (CENWAT), cookers (CKR1), fires (HTR1)
✓Gas Safe registration — legally required to work on gas
✓Unvented hot water systems (often combined)
✓F-Gas qualification if working with refrigerants (heat pumps)

Key regulatory difference

Gas engineers are legally required to be on the Gas Safe Register to carry out any gas work. This is a legal requirement enforced by the Health and Safety Executive. Electricians are not legally required to be registered, though Part P and competent person schemes provide similar practical requirements.

Earnings Comparison

Both trades offer competitive earnings, with electricians holding a slight edge on average. See our full electrician salary breakdown for more detail.

Employed salaries

✓Electrician average: 33,000 to 38,000 pounds per year
✓Gas engineer average: 30,000 to 35,000 pounds per year
✓Electrician with specialism (EV, data centres): 40,000 to 65,000 pounds
✓Gas engineer running own business: 40,000 to 50,000 pounds

Self-employed day rates

✓Electrician: 200 to 400 pounds per day
✓Gas engineer: 200 to 350 pounds per day
✓EV charging specialist: 300 to 500 pounds per day
✓Boiler installation (supply and fit): 500 to 800 pounds per job

Gas engineers benefit from high-value boiler installation work — a combi boiler replacement can be charged at 2,000 to 3,500 pounds including the unit. However, the future of this work is uncertain. Electricians have a wider range of specialism options, each commanding premium rates.

The Gas Boiler Phase-Out

The single biggest factor differentiating these two careers is the government's plan to phase out gas heating. Understanding the timeline is essential for making an informed career decision.

The timeline

✓2025: No new gas boilers in new-build homes (already in effect)
✓2035: Planned ban on all new gas boiler installations
✓2050: Net zero target — gas heating expected to be largely replaced

Impact on gas engineers

The ban does not mean gas engineers will have no work overnight. The UK has approximately 22 million gas boilers installed. These will need servicing, repairing, and eventually replacing with heat pumps or other low-carbon alternatives over many years. However, the volume of new gas installation work will decline steadily.

Impact on electricians

Electricians are the direct beneficiaries of this transition. Every heat pump needs electrical installation. Every home moving away from gas needs upgraded electrical capacity. The phase-out of gas is creating new work for electricians, not removing it.

Smart gas engineers are adapting

Many forward-thinking gas engineers are already adding heat pump installation qualifications to their skill set. The smart approach is to combine gas and renewable heating skills, managing the transition rather than being caught by it.

Scope of Work and Variety

The range of work available in each trade differs, and this affects both job variety and long-term career options.

Electrician scope

✓Domestic installation and rewiring
✓Commercial and industrial electrical systems
✓Testing, inspection, and certification (EICRs)
✓EV charger installation
✓Solar PV and battery storage
✓Data centre electrical systems
✓Fire alarm and security systems
✓Smart home technology
✓Building management systems (BMS)

Gas engineer scope

✓Boiler installation, servicing, and repair
✓Gas cooker and hob fitting
✓Gas fire installation and servicing
✓Central heating system installation
✓Landlord gas safety certificates (CP12)
✓Commercial gas systems (with additional qualifications)
✓Heat pump installation (with F-Gas qualification)

Electricians have a significantly wider scope of work, with multiple specialist areas they can move into. Gas engineers have a more focused scope that is heavily centred on heating. This makes electrical work more versatile as a long-term career.

Current and Future Demand

Both trades face skills shortages today. The difference lies in the trajectory of demand over the next decade.

Electrician demand trajectory

Demand for electricians is growing rapidly and is projected to continue growing through at least 2050. The drivers are structural — net zero legislation, EV adoption, solar targets, and housing construction — and are backed by legally binding government commitments.

Gas engineer demand trajectory

Demand for gas engineers remains strong in the short term, driven by the large installed base of gas boilers needing servicing. However, demand for new gas installations will decline from 2025 in new builds and from 2035 more broadly. Gas engineers who diversify into heat pumps and renewables will continue to thrive.

The long-term outlook strongly favours electricians. Every major trend in energy and technology — electrification, decarbonisation, smart buildings, electric vehicles — creates more work for electricians while reducing traditional gas engineer work. For a deeper look at why, see our guide on whether electrician is a good career.

Gas Engineers Retraining as Electricians

A growing number of gas engineers are retraining as electricians or adding electrical qualifications to their existing skills. This is a practical response to the changing energy landscape.

✓Gas engineers have strong existing trade skills that transfer well
✓Technical aptitude and regulatory knowledge provide a solid foundation
✓The Level 2 and Level 3 diplomas take approximately 18-24 months
✓Combining gas and electrical skills creates a highly versatile skill set
✓Heat pump installations require both gas decommissioning and electrical connection skills
✓Dual-qualified tradespeople can manage complete heating changeover projects

If you are a gas engineer considering adding electrical skills, the adult diploma route is the most efficient pathway. Your existing trade experience means you will likely find the practical elements straightforward.

Frequently Asked Questions

Do gas engineers or electricians earn more?

On average, electricians earn slightly more at 33,000 to 38,000 pounds compared to 30,000 to 35,000 pounds for gas engineers. However, experienced gas engineers with their own boiler installation business can earn 40,000 to 50,000 pounds. The earning gap widens in favour of electricians when specialist roles like data centre or EV work are considered.

Will gas engineers still have work after the boiler ban?

Yes, but the nature of the work will change. Existing gas boilers will need servicing and repair for decades after the ban on new installations. However, new installation work will decline. Many gas engineers are proactively retraining in heat pump installation to future-proof their careers.

Is it worth becoming a gas engineer in 2026?

Gas engineering remains a well-paid trade with strong current demand. However, anyone entering the profession should plan for the transition away from gas heating. Combining gas qualifications with heat pump and renewable energy skills is the smartest approach for new entrants.

Can a gas engineer retrain as an electrician?

Yes. Gas engineers can take the City and Guilds 2365 Level 2 and Level 3 diplomas to qualify as electricians. Their existing trade skills and technical aptitude typically make them strong candidates. The combined training takes approximately 18 to 24 months.

Which trade is easier to get into?

Both have similar entry requirements and training timelines. Electrician training involves more theory and regulation study, while gas engineering requires mandatory Gas Safe registration with ACS assessments. Neither is significantly easier than the other, but they suit different skill sets.
