How to Become an Electrician or Plumber in the UK: Qualifications, Costs and Pay

Published November 9, 2026 by Admin Staff

Electricians and plumbers are among the most in-demand skilled tradespeople in the UK. The work is varied, the pay is good once you are qualified, and you can work for an employer or build your own business. But the routes are not always clear: some training adverts promise a qualification in weeks, while the real route takes years. This guide explains the qualifications, the apprenticeship and college routes, what training costs, what electricians and plumbers earn in 2026, which registrations the law requires and how to avoid training scams.

Quick answer: The most common route into both trades is a three to four year apprenticeship, where you earn a wage and your training is funded. Electricians finish with a Level 3 qualification, the 18th Edition wiring regulations and the AM2 assessment, which opens the way to an ECS Gold Card. Plumbers complete Level 2 and 3 plumbing qualifications, and need Gas Safe registration before they can legally work on gas. Fully qualified electricians commonly earn around £28,000 to £35,000 when newly qualified, and experienced plumbers and gas engineers often earn more.

Electrician or plumber: how do they compare?

	Electrician	Plumber
What you do	Install, test, inspect and repair electrical systems in homes, businesses and industry	Install and repair water supply, heating, drainage and, with Gas Safe registration, gas systems
Main qualifications	Level 2 and 3 electrotechnical diplomas or apprenticeship, NVQ Level 3, 18th Edition, AM2 assessment	Level 2 and 3 plumbing and heating diplomas or apprenticeship, NVQ, plus ACS gas assessments
Legal registration	No single licence for general electrical work, but industry cards and competent person schemes are expected by employers and customers	Gas Safe registration is a legal requirement for any gas work
Typical training time	3 to 4 years by apprenticeship	2 to 4 years by apprenticeship, or less by intensive courses plus experience
Industry card	ECS card, with the Gold Card for qualified electricians	JIB plumbing card, which can be used with a CSCS card for site work
Common work	Domestic rewiring, commercial installations, maintenance, testing and inspection, EV chargers and solar	Bathrooms, boilers, central heating, leaks, drainage and emergency call-outs

Some people train in both, or add related specialisms such as heating, renewables and electric vehicle charging.

Becoming an electrician

Route 1: Electrical apprenticeship

The apprenticeship is the standard route. You work for an electrical contractor, learn on site and attend college or a training centre, usually one day a week or in blocks.

Length: typically about 3.5 to 4 years.
Qualifications: a Level 3 electrotechnical qualification (the knowledge element, often City & Guilds 2365 or an equivalent), an NVQ Level 3 portfolio showing on-site competence, the 18th Edition Wiring Regulations certificate (BS 7671) and an end-point assessment that includes the AM2 practical assessment.
Cost to you: training is employer and government funded, so there are normally no course fees. You may need to buy tools and work boots, with one guide estimating £500 to £1,000.
Pay: you earn a wage from day one. The legal minimum for apprentices is £8.00 an hour from April 2026 (for under-19s and those aged 19 or over in their first year). JIB-registered employers use graded apprentice rates which one source gives as about £8.16 an hour at Stage 1 up to £14.03 at Stage 4 (more in London). After the first year, apprentices aged 19 or over must receive at least the minimum wage for their age. See our guide to apprenticeships in the UK.
Entry: typically GCSEs in English and maths, and an aptitude test and interview with the employer. Competition for places with good contractors can be strong.

One guide estimates that apprentice wages across the four years run from about £15,900 to £27,400, which may not suit people with mortgages or families.

Route 2: College and adult training routes

If you cannot get an apprenticeship, or you are a career changer, you can train through a college or training provider.

Level 2 diploma in electrical installation (often City & Guilds 2365 Level 2).
Level 3 diploma in electrotechnical services.
18th Edition (2382) certificate. Current guidance says it now covers BS 7671:2018+A4:2026, so check you are doing the right edition.
Work experience and an NVQ Level 3 portfolio. To build the portfolio you need to work on real installations, usually as a trainee under a qualified electrician. One 2026 guide says the newer 5357 NVQ replaces the old 2357 and requires a minimum period of on-site experience, so check with your provider.
AM2 (or AM2S) assessment, the practical test.
ECS Gold Card application.

Self-funded routes can cost several thousand pounds. One guide puts adult training fees at £5,000 to £12,000 for the diplomas, NVQ assessment, AM2 and 18th Edition combined, but prices vary a lot between providers.

A warning: short “become an electrician in a few weeks” courses can teach basics, but they do not make you a fully qualified electrician. You still need the Level 3 qualification, a competence portfolio from real work, the 18th Edition and the AM2 to qualify, and industry sources say this takes years of experience.

Typical costs for electricians

Item	Typical cost
Apprenticeship training	£0 to you (employer-funded)
Level 3 tuition (if self-funded or partly funded)	£0 to £3,500 (more at private providers)
18th Edition (BS 7671)	About £400 to £600
AM2 or AM2S assessment	About £700 to £1,300, often paid by employers on apprenticeships
Tools and protective equipment	About £500 to £1,000, rising if you work for yourself
ECS card	Roughly £30 to £60, depending on card and source
Adult self-funded route (all stages)	About £5,000 to £12,000

These figures come from several training guides that differ, so check each provider’s current price.

Qualifications and registrations for electricians

ECS Gold Card. The industry-standard card showing you are a fully qualified electrician. You normally need the NVQ Level 3, the 18th Edition and the AM2.
Inspection and testing qualifications, such as the 2391, which can lead to higher JIB grades.
Competent person schemes. Self-employed electricians who do domestic work often join a scheme, such as NICEIC or NAPIT, so they can self-certify certain notifiable work under the Building Regulations. Check the current requirements.
Insurance. Public liability insurance is normally essential if you work for yourself.

What electricians earn

In 2026, the JIB national rates for electricians (transport provided, from 5 January 2026) are reported at about:

JIB grade	Hourly rate
Electrician	About £18.38
Approved Electrician (with inspection and testing qualifications)	About £20.08
Technician	About £22.70

Other guides suggest:

Newly qualified electricians: about £25,000 to £32,000, or £28,000 to £35,000, depending on the source and region
Experienced electricians: about £35,000 to £45,000 in employment, and more for specialists or self-employed electricians

Pay depends on location, employer, specialism and whether you work on JIB terms. Self-employed electricians set their own rates and carry their own costs and risks. See our National Minimum Wage 2026 guide for the legal minimum for apprentices.

Becoming a plumber

Route 1: Plumbing apprenticeship

Standard: the Level 3 Plumbing and Domestic Heating Technician apprenticeship (in Scotland, the equivalent is run through SNIPEF).
Length: typically three to four years, and some sources say two to four.
How it works: you work for a plumbing or heating company and attend college, often one day a week or in blocks, to complete NVQ Level 2 and 3 qualifications and an end-point assessment.
Cost to you: nothing for the training, which is funded by the government and the employer.
Pay: at least the apprentice minimum of £8.00 an hour from April 2026 (for under-19s and those aged 19 or over in their first year), and then the minimum for your age. One guide estimates apprentice plumbers earn about £16,500 to £21,000 a year, though pay varies.

Route 2: College or intensive training

Level 2 Diploma in Plumbing (often City & Guilds 6035-02), taking one to two years part time, or in intensive courses of a few weeks to months.
Level 2 NVQ, which proves on-site competence and unlocks a JIB plumbing card for site work.
Level 3 Diploma and NVQ, for more advanced work, such as unvented hot water and system design, and required before you are treated as fully qualified by many employers.
Gas training and ACS assessments if you want to work on gas.

Costs vary widely between providers:

Item	Typical cost
Apprenticeship	£0 to you
Level 2 diploma at college	Free for 16 to 18 year olds and often funded for adults, otherwise about £1,000 to £4,000
Level 3 diploma	About £2,500 to £6,000
Private fast-track plumbing course	About £4,000 to £9,000, with some packages at £7,000 to £12,000 including gas
Gas training and ACS assessments	Estimates range from about £500 to £1,500 up to £1,500 to £4,000 for domestic gas modules

Sources differ a lot, so check what is included and get several quotes.

Do plumbers need a licence? Gas Safe registration

General plumbing (water supply, taps, sanitary ware, drainage) does not need a statutory licence, though you should hold recognised qualifications and follow the water regulations. The WaterSafe scheme lists approved plumbers for water-fitting work.
Gas work is different. Anyone who installs, services or repairs gas appliances, pipework or flues must be on the Gas Safe Register. Working on gas without registration is a criminal offence.
How to register. You complete your plumbing qualifications and then pass ACS (Accredited Certification Scheme) gas assessments in the areas you want to cover, such as boilers, cookers and fires, then apply to join Gas Safe. Sources list modules including CCN1 and CENWAT as common core units. The ACS assessment typically needs to be renewed every five years.
Costs. ACS assessments and the annual Gas Safe registration fee vary, and secondary sources quote very different figures (for example £50 to £120 a year in one and £300 to £600 in another). Check the current fee on the Gas Safe Register website.

Gas Safe registration is the single biggest upgrade for many plumbers, because heating and boiler work are among the best-paid areas.

What plumbers earn

Guides in 2026 suggest:

Experienced employed plumbers: around £35,000 to £46,000, with Gas Safe engineers earning more
Self-employed day rates: about £250 to £350, and call-out fees of £60 to £120
Gas Safe engineers: hourly charges of £60 to £100 or more are reported, with boiler installations commonly quoted at £1,500 to £3,500 and full central heating systems at £4,000 to £8,000

Those figures are what customers may be charged, not what you take home. Your income depends on how much work you win, your costs, travel, insurance and tax. Check pay for your area on current adverts, and see our jobs board.

Which route is right for you?

Your situation	Suggested route
School leaver or under 19	Apply for several apprenticeships at once, with a college Level 2 as a backup
Adult career changer with savings	College Level 2 and 3, then find a trainee position to build your portfolio
Career changer who needs to earn	Look for adult apprenticeships, or trainee and labouring jobs while you study part time
Already working in construction	Ask your employer about training, or add a trade qualification. See our guide to CSCS cards and construction jobs
Over 50 or returning to work	Trades are open to older learners, though some employers are cautious about adult apprentice wages. See our guide to jobs for over 50s and returners in the UK

One guide notes that some employers are cautious about the higher wage cost of adult apprentices, so many career changers complete a college Level 2 first and apply with evidence in hand.

How to get started: step by step

Decide on a trade and look at what each involves. Try work experience or shadowing if you can.
Check the basics. GCSE English and maths are helpful, and many employers ask for them. Some apprenticeships have aptitude tests.
Search for apprenticeships on the government’s Find an apprenticeship service, on employer sites and through the JIB and local colleges. Apply to many.
Prepare your CV and cover letter. Show reliability, practical interest and any relevant experience. See our guides to writing a UK CV with no experience and writing a cover letter in the UK.
Prepare for the interview. Employers look for reliability, interest in the trade, willingness to learn and good timekeeping. See our guide to common interview questions and answers in the UK.
Get a CSCS card if your work involves construction sites. See our guide to CSCS cards and construction jobs.
Build experience and qualifications step by step, keeping a record of your work for your portfolio.
Register with the right bodies once you qualify, such as ECS, Gas Safe and a competent person scheme.
Decide whether to stay employed or go self-employed. See below.

Employed or self-employed?

Many qualified electricians and plumbers eventually work for themselves. That brings freedom and higher potential income, but also costs and responsibilities.

Employed: steady wage, holiday and sick pay, a van and tools often provided, and training. Pay is lower than top self-employed earnings.

Self-employed: you set your rates and hours, but you need to find customers, handle quotes and invoices, buy insurance and tools, pay your own tax and National Insurance and cover quiet periods and sickness. Many trades work under the Construction Industry Scheme on larger sites. See our guides to how to become self-employed in the UK and CSCS cards and construction jobs for tax and CIS.

One guide estimates starting a plumbing business costs about £5,000 to £12,000 for a qualified plumber with a second-hand van, and more if you train from scratch and add Gas Safe registration. Think about insurance, tools, vehicle, marketing and certification costs before you commit.

Working conditions and your rights

Physical work. Both trades involve manual work, kneeling, lifting and working in confined spaces.
Health and safety. Training, protective equipment and safe working practices are essential, particularly around electricity, gas and heights.
Employee rights. As an employee or apprentice, you have rights to the minimum wage, holiday pay and sick pay. See our guides to holiday entitlement and holiday pay and Statutory Sick Pay 2026.
Check your status. If a firm calls you self-employed but controls your hours, tools and work, you may be an employee or worker with more rights. See our guide to delivery driver jobs for how status works.
Right to work. You must have the right to work in the UK. See our guide to right to work checks in the UK.
Women and diversity in the trades. Women remain a small share of electricians and plumbers, but employers and training providers are working to widen recruitment. You have the same legal protections as any other worker.
Disability and health. You can ask for reasonable adjustments, and Access to Work may help. See our guide to disability and work in the UK.

Scams and risks

Trade training attracts both good and bad providers. Watch for:

“Qualify in weeks” promises and guaranteed jobs or income. Real qualification takes years of experience for electricians, and plumbers need recognised qualifications and gas assessments.
Providers that are not approved, or that cannot show recognised awarding body accreditation. Check with the awarding body, such as City & Guilds, and the relevant scheme.
Upfront payment for a “guaranteed” apprenticeship or job. Apprenticeships are free for the apprentice. See our guides to apprenticeships in the UK and how to spot a fake job advert in the UK.
Fake cards and certificates. Using a fake ECS, CSCS or Gas Safe card is illegal and dangerous. You can check Gas Safe engineers on the official register.
Bogus tradespeople. If you are hiring a tradesperson yourself, always check Gas Safe, WaterSafe and competent person scheme registration, insurance and reviews.
Overseas offers of trade jobs with visas for a fee. Check carefully, because many trade roles are not eligible for sponsorship. See our guide to jobs with visa sponsorship in the UK.

Career progression

Electricians: approved electrician and technician grades, inspection and testing, domestic installer, contracts manager, estimator, designer, and specialisms such as EV chargers, solar and battery storage, fire alarms or industrial controls
Plumbers: heating engineer, Gas Safe engineer, renewable heating such as heat pumps, bathroom installer, contracts or site manager and running your own business
Both: assessor and trainer roles, health and safety, project management, and starting a firm that employs apprentices
