Why the law insists on a licensed contractor
The Central Electricity Authority (Measures relating to Safety and Electric Supply) Regulations, 2023 came into force in June 2023 and replaced the 2010 regulations. Regulation 31 says that no electrical installation work, including additions, alterations, repairs and adjustments, can be carried out for a consumer except 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. The only things left out are like-for-like replacement of lamps, fans, fuses, switches and domestic appliances up to 250 V that do not change the capacity or character of the installation.
Sub-regulation (2) is the part people miss: work done in breach of this rule shall not be energised or connected to the supplier's network. So an ESCOM is not being difficult when it refuses a test report from an unlicensed electrician. It is following the regulation.
Who issues the licence in Karnataka
Licences are issued under the Karnataka (Licensing of Electrical Contractors, Special Wiring Permit and Grant of Certificates and Permits to Electrical Supervisors and Wiremen) Rules, 2012, which have been amended several times since. The work is handled by the Licensing Advisory and Examination Board under the Department of Electrical Inspectorate, Government of Karnataka. The department is headed by the Chief Electrical Inspector to Government, which is why people still say "CEIG licence".
The department's old EISOFT portal handled applications until 31 August 2021. Since 1 September 2021, applications for licences, permits and renewals go through Seva Sindhu.
Licence classes and what each can do
Rule 11 of the 2012 Rules sets four classes of contractor licence. Each class also has a minimum staff requirement, and the permits of those staff must be endorsed to that contractor alone.
| Class | Work allowed | Minimum staff (Rules, 2012) | Typical jobs |
|---|---|---|---|
| Super Grade | Low, medium, high and extra high voltage | At least one Grade 1 supervisor and three wiremen, in sole employment | EHT substations, large industry |
| Class 1 | Up to and including 33 kV | At least one supervisor and one wireman | 11 kV HT connections, transformers, layouts, factories |
| Class 2 | Up to and including 650 V | One supervisor and one wireman | Three-phase homes, shops, apartments on LT, small industry |
| Class 3 | Up to 250 V | One supervisor and one wireman | Single-phase house wiring only |
In plain terms: a Class 3 contractor can sign for a single-phase house but not a three-phase one. A three-phase house, a shop on three-phase or an LT industry needs at least Class 2. Anything with a transformer or an 11 kV line, such as an HT connection or a layout DTC, needs Class 1 or Super Grade. See our guides on HT connections and layout electrification.
Under the Rules, a first licence is issued for up to one year and can then be renewed for up to five years at a time, if the contractor still has the required staff, instruments and solvency papers.
Supervisor certificates and wireman permits
The licence belongs to the firm. The people doing the work hold their own papers:
- Electrical Supervisor certificate of competency and permit. The supervisor directs the work and signs the technical side. The general certificate covers all voltage classes except mines; Grade 2 is limited to 33 kV; mines need a separate endorsement.
- Wireman permit (Grade 1 and Grade 2). The person actually pulling wires, terminating and testing. Grade 1 is generally for ITI-qualified wiremen; Grade 2 for experienced wiremen without an ITI certificate.
- Special Wiring Permit. Lets an industry do its own maintenance and internal wiring with its own supervisor and wiremen. It is not a licence to work for other people.
A supervisor or wireman permit has to be endorsed to one contractor. A common trick is a contractor who "borrows" a supervisor's name. You can check the endorsement (see below).
How to check a contractor before you hire
- 1Ask for the licence number, class and expiry date
Ask to see the licence certificate, not a visiting card.
- ?Is the class enough for your job?Yes Go to the next checkNo Find a higher-class contractor
- 3Check the endorsement online
The Inspectorate's endorsement verification page searches by licence number or supervisor and wireman permit number.
- ?Does the supervisor named on the licence actually come to site?Yes Go aheadNo Ask who will sign the test report
- ✓Agree scope, test report and drawings in writing
The 2012 Rules also require the contractor to keep a work register, execute an agreement with the consumer, file a work commencement notice and a completion and test report, and put up a board at site with the contractor, supervisor and wireman details. A licensed firm that does none of these is cutting corners elsewhere too.
Why ESCOMs want the licensed contractor's test report
Regulation 33 of the CEA 2023 regulations says that before giving a new or additional supply, or reconnecting after six months, the supplier must either test the installation itself or accept the test results submitted by the consumer, duly signed by the licensed electrical contractor. Regulation 35 adds that the supplier must check insulation resistance before connecting. In practice every ESCOM in Karnataka, from BESCOM to GESCOM, relies on the contractor's report rather than testing each house itself.
A good test report records insulation resistance, earth resistance of each pit, polarity, RCCB trip test and the connected load. It is not a printed form with a rubber stamp. If the report is false and something goes wrong, the contractor's licence is at risk: Rule 37 allows suspension or cancellation for violations.
For installations up to the voltage the State notifies for self-certification, the owner submits a self-certification report to the Electrical Inspector, usually prepared with the contractor. Above it, the Inspector approves drawings and inspects. Our guide on CEIG drawing approval and safety inspection covers that route.
What goes wrong at the ESCOM counter
Most rejected applications we see have nothing to do with the wiring itself. They fail on paperwork that ties back to the licence:
- Wrong class. A Class 3 contractor's report submitted for a three-phase house. The section office sends it back and the owner loses a week.
- Expired licence or permit. The licence was valid when the job started but lapsed before the report was signed. Renewal dates matter.
- Supervisor not endorsed. The supervisor who signed is endorsed to a different firm. The signature is not valid for this contractor.
- Readings missing. Insulation resistance and earth resistance columns left blank or filled with "OK". Some offices accept it, some do not, and the ones that do not are right.
- Load mismatch. The connected load in the test report does not match the load applied for. This causes trouble later with the sanctioned load and the meter; see load enhancement.
- No wiring diagram. Several ESCOM offices ask for a simple wiring diagram along with the report.
None of this is hard for a working licensed contractor. If yours cannot produce a licence copy, a supervisor and a filled-in test report, that tells you how the rest of the job was done.
If you are an electrician thinking of getting your own licence, the route is a wireman permit first, then working under a licensed firm, and applying for a contractor licence once you can meet the staff and instrument requirements for the class you want. The Board conducts the examinations for supervisor and wireman permits; check the current notification and eligibility on Seva Sindhu or with the Inspectorate.
When the job goes wrong after you hire
Most disputes with contractors come down to three things: the test report, defects found at inspection, and work left half-done.
- The contractor will not sign the test report. Without it the ESCOM will not connect you. Ask in writing, quoting your agreement. If that fails, another licensed contractor can test and sign, but expect them to test the whole installation again and to refuse to sign for work they cannot see, such as concealed earthing. This is why the written agreement and photos of the conduit and earth pits during construction matter.
- Defects found at inspection. If the ESCOM or the Electrical Inspector lists defects, the contractor who signed must correct them. Readings far from what was recorded, such as a high earth resistance, suggest the report was not based on real tests. Our earthing and testing checklist shows what should have been measured.
- RCCB trips from day one. This usually points to a wiring fault such as mixed neutrals, not a bad RCCB. Ask the contractor to trace it rather than remove the RCCB. See MCB, RCCB and RCBO for the common causes.
- A false report or work by an unlicensed person under a licence. You can complain in writing to the jurisdictional Electrical Inspector's office with copies of the agreement, the report and photos. Rule 37 of the 2012 Rules allows the licence to be suspended or cancelled.
For what the ESCOM needs after the wiring is done, see our guide to a permanent connection for a new house.

Questions
Who issues the electrical contractor licence in Karnataka?
The Licensing Advisory and Examination Board under the Department of Electrical Inspectorate, Government of Karnataka, under the Karnataka licensing rules of 2012. Applications are made through Seva Sindhu.
Can a Class 3 contractor do three-phase wiring?
No. Class 3 is limited to 250 V, which means single-phase work. Three-phase installations up to 650 V need at least a Class 2 licence.
What licence is needed for a transformer or HT connection?
A Class 1 licence covers work up to and including 33 kV, which includes 11 kV HT connections and distribution transformers. Super Grade covers all voltages.
How can I verify an electrical contractor's licence?
Ask for the licence number and check it on the Electrical Inspectorate's endorsement verification page, which also shows the supervisor and wireman permits endorsed to the firm. You can also ask the jurisdictional Electrical Inspector's office.
Can my local electrician sign the test report for a new connection?
Only if he holds or works for a licensed contractor of the right class. CEA Regulation 31 says work by unlicensed persons shall not be energised, and ESCOMs accept test results signed by a licensed contractor.
Do I need a licensed contractor to change a fan or switch?
No. Like-for-like replacement of lamps, fans, fuses, switches and domestic appliances up to 250 V is exempt, as long as it does not change the capacity or character of the installation.
