Every home, shop, office and factory needs reliable electricians and plumbers: new wiring, fans and lights, short circuits, leaking taps, blocked drains, water tanks, pumps and geysers. Good tradespeople are always in demand, and customers who find one they trust call them again and again. An electrical or plumbing business can start with one skilled person and a set of tools, and grow into a contracting firm with a team, maintenance contracts and commercial clients. This guide explains how to start an electrician or plumbing business in India, from licences and costs to finding your first customers.
This guide explains the training and licences you need, how to work safely, how to price your work and how to grow.
Key points
Table of Contents
- Electrical work is regulated. Electrical installations must be done under licensed electrical contractors with qualified, licensed supervisors and wiremen, following the Central Electricity Authority’s safety regulations and your state’s licensing rules.
- Plumbing licences are required by some municipal bodies and water utilities, especially for new connections and major work.
- Safety first: isolate power, use the right protective equipment and follow standards. Shortcuts cause fires, shocks and floods.
- Clear rate cards and written quotes build trust and prevent disputes.
- Annual maintenance contracts with housing societies, shops and offices give steady income.
Step 1: Get trained
- ITI courses for electricians, wiremen and plumbers are the traditional route, and many state licences require them.
- Skill India courses in electrical and plumbing trades, with recognised certificates, through the relevant sector skill councils. Find centres on Skill India Digital.
- Apprenticeship with an experienced contractor: the fastest way to learn real-world work.
- Keep learning: solar, inverters and batteries, EV chargers, smart home devices, modern plumbing materials and water-saving fittings are all growing areas.
Step 2: Licences and registrations
Electrical work
India’s electricity safety rules, made by the Central Electricity Authority (CEA) under the Electricity Act, 2003, require electrical installation work to be carried out by or under the supervision of qualified, licensed persons. In practice, in most states:
- wireman permits or competency certificates are issued to qualified electricians
- supervisor certificates are issued to people with higher qualifications and experience
- electrical contractor licences are issued to businesses that employ licensed supervisors and wiremen, and are needed for wiring new buildings and for work that must be certified to the DISCOM
Licensing is run by each state’s electrical licensing board or electrical inspectorate, with its own grades, fees and renewal periods. Check your state’s rules. Without the right licence, you can’t legally carry out or certify many kinds of electrical work.
Plumbing work
Some municipal corporations and water utilities require licensed plumbers for new water and sewer connections and certain other work. Elsewhere, there may be no formal licence, but customers and builders increasingly prefer certified plumbers.
Business registrations
- Shops and establishments registration if you have a shop or office. See shop and establishment registration and trade licences.
- GST registration once turnover crosses ₹20 lakh for services in most states, or earlier if business clients need GST invoices. See GST registration for small businesses.
- Udyam registration: free, and useful for loans and government work. See our Udyam guide.
- Contractor registration with the PWD, municipality or other departments if you bid for government contracts.
Step 3: Tools and equipment
Electrician’s kit: insulated hand tools, a multimeter and clamp meter, a voltage tester, an insulation resistance tester, a drill and chasing tools, wire strippers and crimpers, ladders, and personal protective equipment (insulated gloves, safety shoes, eye protection).
Plumber’s kit: pipe wrenches, cutters and threading tools, a PPR or CPVC welding machine, drain cleaning tools and augers, a pressure tester, sealants and fittings, ladders and protective equipment.
Keep a small stock of common parts, such as switches, MCBs, wires, taps, valves and fittings, so you can finish most jobs in one visit.
Step 4: GST on your work
Repair, maintenance and installation services are generally taxed at 18% GST. If you supply materials as well as labour on larger jobs, the job may be treated as a works contract with its own GST treatment. Show labour and materials clearly on your invoices, and ask a chartered accountant about larger contracts. Make invoices free with Advanton’s GST invoice generator.
Step 5: Work safely
Electrical:
- isolate the supply and confirm it’s dead before working
- use correctly rated wires, MCBs, RCCBs and earthing
- never bypass protection devices
- test the installation, including insulation and earthing, before handing over
- follow the relevant Indian standards for wiring
Plumbing:
- shut off the water supply and relieve pressure before working
- use materials suited to hot or cold water and drinking water
- pressure-test new lines before closing walls
- slope drains correctly and seal joints properly
For both: use ladders safely, wear protective equipment, clean up after every job, and never leave a site unsafe.
Common jobs, done well
Electrical:
- Tripping MCBs and short circuits: find the faulty circuit or appliance by isolating circuits one by one, check for damaged wiring and loose connections, and never "fix" a trip by fitting a higher-rated breaker.
- Earthing problems: test earth resistance, and repair or replace earth pits and conductors. Poor earthing makes shocks and appliance damage more likely.
- RCCB installation: recommend residual current protection for homes, especially bathrooms and kitchens, and explain why it saves lives.
- Old wiring: many older homes have undersized or deteriorated wiring. Offer a safety inspection and a written report before suggesting rewiring.
Plumbing:
- Leaks: find the source before opening walls, using pressure tests and moisture checks, and fix the cause, not just the stain.
- Blocked drains: clear them with the right tools, and explain to customers what causes blockages, such as grease and wipes.
- Low water pressure: check tanks, pumps, valves and pipe sizes before replacing fittings.
- Geysers: install with proper pressure relief valves, correct wiring and earthing, and check mounting strength.
For every job: explain the problem and the fix in simple words, show the customer the faulty part you’ve replaced, and suggest preventive steps. Customers remember a tradesperson who explains.
Step 6: Pricing, quotes and payments
- Publish a rate card for common jobs: fan installation, switchboard repair, tap replacement, drain cleaning, geyser installation and so on.
- Charge a visiting fee, adjusted against the bill if the customer goes ahead.
- Quote in writing for larger jobs, with labour and materials separated, and get approval before starting.
- Explain extra work before doing it.
- Take an advance on larger jobs that need materials.
- Collect payment by UPI on completion, and give a bill with your warranty on workmanship.

Running a small team
Once you have helpers or a second technician, simple systems keep work flowing:
- a daily job list shared on WhatsApp each morning, with addresses, times and job details
- job cards for each visit: work done, materials used, time taken and the customer’s signature or approval
- a stock kit for each technician, refilled every evening, so jobs aren’t held up for parts
- clear rules on safety, punctuality, behaviour in customers’ homes and handling payments
- a weekly review of jobs, complaints and callbacks
Step 7: Annual maintenance contracts
Housing societies, shops, offices, schools, hospitals and small factories need regular electrical and plumbing upkeep. An annual maintenance contract (AMC) with a set number of visits, a response time for breakdowns, and agreed rates for materials gives you:
- steady monthly or yearly income
- planned work in quieter periods
- a stream of extra jobs and referrals
Write the scope, response times and rates clearly, and keep a log of every visit.
Step 8: Get customers
- Google Business Profile: "electrician near me" and "plumber near me" are among the most common local searches. Add your service area, services, prices and reviews.
- The India Business Directory: list your business free.
- WhatsApp: quotes from photos, booking confirmations and job updates.
- Builders, contractors and interior designers: steady work on new homes and renovations.
- Hardware and electrical shops: many customers ask shopkeepers to recommend someone.
- Home services apps: bring bookings, though they take a commission.
Step 9: Grow your business
- Hire helpers and apprentices, and train them into licensed tradespeople.
- Take on contracts: new building wiring and plumbing, renovations and commercial fit-outs, with the right licence grade.
- Add specialities: solar rooftop systems (see how to start a solar installation business), inverters and batteries, EV chargers, water purifiers and pumps.
- Funding: a Mudra Kishore or Tarun loan can pay for tools, a vehicle and stock. See business loans and government schemes.
Check the full cost of each hire, including PF and ESI where they apply, with Advanton’s hiring cost calculator.
Common mistakes
- Doing electrical work without the required licence, which is unsafe and can be illegal.
- Using cheap, uncertified materials that fail or cause fires.
- No written quotes for larger jobs.
- Leaving sites dirty or unsafe.
- Taking on more jobs than you can finish, leaving customers waiting.
