Electrical Contractor Licences in India: Classes, States and What to Verify Before Award
In India an electrical contractor must hold a licence from the State Government before doing installation work for a consumer, under regulation 31 of the CEA safety regulations of 2023. Each state's licensing board defines the classes, usually by voltage and scope, and requires a certified supervisor and permit-holding wiremen on the contractor's payroll. Before award, verify the class, its validity, the named supervisor and, for an out-of-state contractor, the permission to work in your state.
What does the law require?
Regulation 31 of the Central Electricity Authority (Measures relating to Safety and Electric Supply) Regulations, 2023 says that installation work, including additions, alterations, repairs and adjustments, is carried out only by an electrical contractor licensed by the State Government, under the direct supervision of a person holding a certificate of competency, and by a person holding a permit issued or recognised by the State Government. Replacing lamps, fans, fuses, switches and domestic appliances up to 250 V without altering capacity is excluded. Work done in breach of this rule shall not be energised or connected to a supplier's works.
Two further points matter to an owner. For works executed for the Central Government, and for installations in mines, oil-fields and railways, a licence from any one state or union territory is enough and no further state licence is needed. And under regulation 33 the supplier tests a new installation itself or accepts test results duly signed by a licensed electrical contractor, so the contractor's licence appears on your connection paperwork.
What classes of licence exist?
The regulations leave classes to the states, and the states differ in names, voltage limits and conditions. The Rajasthan Electrical Inspectorate's licence form, issued under its 2016 rules, shows a typical structure:
| Class (Rajasthan) | Scope | Staff on payroll | Other conditions in the schedule |
|---|---|---|---|
| A | All voltage classes | At least two supervisors and four wiremen | Three years as a B or C class contractor with at least 10 HT installations, or an engineer owner with five years of electrical operation and maintenance, or a licence in another state with experience above 33 kV; bank solvency certificate |
| B | Work up to 33 kV | At least one supervisor and two wiremen | A licence from another state also qualifies; lower solvency requirement |
| C | Same scope as B | At least one supervisor and one wireman | For unemployed electrical engineers or Class A supervisors, domiciled in Rajasthan |
| D | House and agricultural wiring up to 650 V | None specified | For holders of a supervisor or wireman certificate or permit |
Other states publish their own. The Puducherry licensing board describes a Grade A licence for low, medium and high voltage up to 33,000 volts and a Grade B licence for low and medium voltage, and says issue of new licences is withheld while its rules are revised. Karnataka's Electrical Inspectorate lists an Electrical Contractor Licence, including a Super Grade, under rules of 2012 with later amendments and a new set of rules in 2025. For Punjab, Haryana, Uttar Pradesh and Delhi, the states in which most of our readers work, we could not retrieve a current class table from a state government page, so read the board's own rules before you rely on a class name from another state.
Why does the supervisor matter more than the licence?
A licence belongs to a firm. The competence belongs to the supervisor. In Rajasthan the contractor must appoint a full-time supervisor holding a competency certificate, with a signed consent that the supervisor holds no contractor's licence and works under no other contractor; the supervisor undertakes to tell the board on leaving. Wiremen carry a similar declaration. If the named supervisor has left, or serves several firms, the licence is a letter-head.
Ask for the supervisor's certificate number and validity, the date of joining, and the permit numbers of the wiremen who will work on your site. These numbers usually appear in the approval file you give the Electrical Inspector; see CEIG approval for factories for how that file is built.
Boards also test the firm's standing. Rajasthan asks for a bank solvency certificate sized to the class, and Karnataka's circulars ask for a bank solvency certificate with new and renewal applications and for ESI and EPF challans with Super Grade renewals. Ask the contractor to show current ones. They tell you whether the firm has a real payroll behind the licence, or whether the licence is being lent to jobs it does not staff.
Can a contractor from another state work on your project?
Often yes, but through the state's route, not by assumption. Regulation 31 refers to a licence issued by the State Government, and the exemption quoted above covers central works only. Rajasthan's schedule provides a temporary contractor's work permit for contractors licensed in other states, for the equivalent class only, valid for the named work order and extendable while the order stands. Other states may handle this differently or not at all. If your project is in a state where the main contractor is not licensed, ask the Electrical Inspectorate in writing what is required, before the contract is signed, and put the licence as a condition precedent.
What should you verify before award?
| Check | What to ask for | Why it matters |
|---|---|---|
| Licence class and validity | Copy of the licence from the state board; renewal receipt if it is due | Class limits voltage and scope; an expired licence invalidates the work |
| Match to your voltage | Your highest voltage against the class scope | A class limited to LT cannot take on an HT substation |
| Supervisor | Competency certificate, joining date, consent letter | Regulation 31 requires direct supervision by a certificate-holder |
| Wiremen | Permit numbers and validity for the named crew | Permits are individual and expire |
| HT experience | List of HT installations with client contacts | Class A style conditions rest on executed HT work |
| Test instruments | Calibration certificates for meggers and earth testers | Regulation 33(3) requires calibrated equipment at specified intervals |
| Out-of-state contractors | The inspectorate's written permission to work in your state | Avoids work that cannot be energised |

Frequently asked
Does an electrical contractor need a licence in India?
Yes. Regulation 31 of the CEA safety regulations of 2023 requires installation work to be done by a contractor licensed by the State Government, under a supervisor with a certificate of competency, by workmen with a permit. Minor replacements of lamps, fans, fuses, switches and domestic appliances up to 250 V that do not alter capacity are excluded. Work in breach cannot be energised.
Which licence class do I need for an HT substation?
The one your state's board allows for your voltage. In Rajasthan, for example, Class B covers work up to 33 kV and Class A covers all voltage classes; Puducherry's Grade A goes up to 33,000 volts. Names and limits differ by state, so compare your highest voltage with the class scope on the contractor's licence, and confirm with the state's licensing board.
Can a contractor licensed in another state work for me?
Possibly, but check. Regulation 31 exempts only central government works, mines, oil-fields and railways from the need for a separate state licence. Rajasthan's schedule offers a temporary work permit to other-state contractors for an equivalent class and a named work order. Ask the inspectorate in your state what it requires and get it in writing before award.
What is a supervisor's certificate of competency?
It is the state's certificate that an individual may supervise electrical work, issued after an examination under the state's rules. Regulation 31 requires installation work to be under the direct supervision of such a person. Boards usually require the supervisor to be a full-time employee of one licensed contractor, so ask for the certificate number, validity and joining date.
Who checks the contractor's licence during approval?
The Electrical Inspector sees the licence and supervisor details in the file when you apply for approval of an installation above the notified voltage, and the DISCOM accepts test results only when signed by a licensed electrical contractor under regulation 33. Verify before award, because a licence problem found at inspection delays energisation.
