12 Best Industrial Electrical Contractors in Mumbai (2026)

Mumbai has thousands of electrical contractors, but only a small number publish the credentials that industrial and commercial work actually requires: HT/LT scope, completed projects, and a verifiable licence. This list covers 12 firms whose public record we checked in August 2026, including our own, with each firm's base, stated scope, and what it is best suited for.

"As stated" means taken from each firm's own website in August 2026. We did not inspect licence certificates, and firms often trade under names that differ from the registered name on their licence. The verification section below shows how to close that gap.

How we picked these electrical contractors

Candidates came from where buyers actually look: Google's results and map pack, AI answers, and the firms we meet on real tenders. We checked each one's website and public listings on 29 August 2026 and kept only firms with a stated Mumbai-region base and an industrial or commercial scope; four candidates failed that bar and were dropped. Full disclosure: Grade Electricals publishes this page and is on the list, held to the same as-stated standard as everyone else. Weigh any entry on five things: licence class and validity, comparable completed projects, self-performed HT scope, testing and commissioning, and support after handover.

The 12 best industrial electrical contractors in Mumbai

1. Grade Electricals Pvt. Ltd. (Andheri East): turnkey projects up to 33 kV and event power

This is our firm, so judge the evidence rather than the placement. Grade has operated since 2004 across four lines: turnkey LV/HV electrical projects up to 33 kV, HT/LT maintenance and testing, temporary power for exhibitions and events, and electrical liaisoning. The maintenance desk services RMUs up to 22 kV and vacuum and SF6 breakers up to 33 kV, with FLIR thermography for fault finding. The events business powers 170+ shows a year and is empanelled with NESCO in Mumbai, Yashobhoomi in Delhi and HITEX in Hyderabad. At IIJS Premiere 2026 at NESCO, Grade was the official power supplier: 32,858+ metres of cabling, 208+ LED fixtures and 300+ protection devices, run for five days without downtime. The firm won Excellence in Essential Services at the Exhibition Excellence Awards in 2023 and 2024, and was honoured at the awards again in 2026. Google rating at the time of writing: 4.1 from 27 reviews.

Best suited for: industrial turnkey projects up to 33 kV, and temporary power where the load, the deadline and the audience are all large. Scope details are on the projects, maintenance and exhibitions pages.

2. Metro Engineering Corporation (Prabhadevi): HT/LT contractor for pharma and process plants

Few Mumbai contractors can show six decades of continuity. Metro states it was established in 1962 and handles HT and LT installations up to 33 kV, including work in hazardous and cleanroom zones, which matters if your plant is pharma or chemical. It lists PCC, MCC, PDB and LDB panel work, AMCs, and PWD licensing and MSME registration among its credentials, and names Laxmi Organic, Vedanta, Croda, Zydus Lifesciences and Akzo Nobel as clients.

Best suited for: pharmaceutical, petrochemical and process plants where zone classification and documentation drive the job.

3. Prabhat Powertech Pvt. Ltd. (Bhandup West): turnkey electrification with in-house LT panels

Prabhat has been executing large turnkey electrification since 1982 and also manufactures LT panels, bus ducts, rising mains and control panels in-house, which shortens one of the longest lead times on a big job. Its client logos lean toward major developers: Raheja, Lodha, Godrej, Kalpataru, Runwal. Stated voltage scope is LT; if your project needs HT substation work, ask specifically who performs it.

Best suited for: developer-led commercial, residential and mixed-use projects where panel supply and installation come from one firm.

4. Rulka Electricals (Bhandup West): electrical and fire-fighting scopes under one contract

Rulka pairs electrical contracting with fire-fighting systems, a combination most electrical firms subcontract. Established in 2004 and describing itself as a government-licensed contractor, it lists turnkey electrification, LT cable laying and energy audits across its group sites. Two scopes under one contract means one point of responsibility at handover.

Best suited for: projects where electrical and fire-system scopes are being tendered together.

5. ASEI (Worli): HT/LT refurbishment with tender-grade documentation

ASEI, established in 2008, states a Class-A electrical contractor licence and works on HT/LT distribution networks. What stands out on its public profile is process: designing with detailed BOQs, tendering and workshop approvals are listed as services in their own right, alongside electrical and ELV refurbishment for star hotels.

Best suited for: refurbishment and fit-out jobs where the client needs tender-grade documentation, not just execution.

6. Shetty Projects & Services (Kurla): switchgear servicing and shutdown maintenance

SPNS is a maintenance specialist rather than a project house. Its stated scope runs to HT and LT switchgear servicing, circuit-breaker and ABB switchgear retrofitting, shutdown maintenance and panel servicing, plus power-quality and electrical-safety audits for banks, data centres and hospitals. Retrofitting a live facility is a different discipline from greenfield installation, and this is one of the few Mumbai firms whose entire public profile is built around it.

Best suited for: switchgear retrofits, shutdown windows and AMC work inside operating facilities.

7. Spark Electrosystems LLP (Mulund East): HT/LT switchgear and power-factor systems

Spark works the switchgear side of the market: HT/LT switchgear, transformers, retrofitting, protection systems and power-factor improvement, with electrical audits and liaisoning alongside. It is an authorized dealer for Schneider Electric Infrastructure, and its stated client base is government and semi-government organisations plus IT and chemical industries.

Best suited for: institutional and government facilities standardised on Schneider switchgear.

8. Connectriq (Marol, Andheri East): new connections and load sanction liaisoning

Connectriq's public profile is the most compliance-forward on this list. It states ISO 9001:2015 certification, government-approved LEC status, designation under regulation 29 of the CEA Regulations 2010, and authority to issue test reports under section 45 of the Indian Electricity Rules 1956. Its services centre on new connections, load extensions and reductions, meter cabins and safety audits, and it also supplies electricity for events. Client logos include Adani, BEST and Mahavitaran.

Best suited for: new utility connections, load sanction changes and the paperwork between you and the distribution company.

9. Anuj Electrical Services (Thane West): power panels and electrical AMC

Anuj has run from Thane since 2000, and its stated scope is the daily infrastructure of commercial buildings: PCC and MCC power panels, earthing, project services and electrical AMCs for offices, factories and warehouses. Its published testimonials reference D Mart and BillDesk facilities.

Best suited for: AMC and panel work for offices, factories and warehouses in the Thane belt.

10. Shree Shiv Electrical (Mazgaon): HT/LT cable laying and substation work

Shree Shiv covers HT/LT cable laying, substation work and SITC of lighting systems from its Mazgaon base, and claims over 1,000 industrial projects alongside larger residential and commercial counts. Its client wall includes DP World, Bombay Dyeing, Trident Hotels, CEAT, Mahindra and the BMC. The firm works across all three segments, so confirm the industrial team's availability rather than the company's.

Best suited for: mixed commercial portfolios in island-city Mumbai where one vendor handles varied small-to-mid scopes.

11. ASP Electricals (Pune, serves Mumbai): HT/LT/EHV claims across the industrial corridor

ASP is the one firm on this list not based in Mumbai: its corporate office is in Pune with works in Ahmednagar MIDC, and Mumbai is a stated service area. Its claims are the widest here, HT, LT and EHV systems with breakers from 1.1 kV to 220 kV, industrial control panels, and energy audits, across automobile, chemical, data-centre and warehouse sectors. Claims that wide deserve the licence-and-projects check below before shortlisting.

Best suited for: plants along the Pune-Mumbai corridor that want one contractor across both cities.

12. Ujala Enterprises (Govandi): top-rated generalist for smaller commercial jobs

Ujala is the smallest-scope firm here and earns its place on a different metric: at the time of writing it holds a 4.9 Google rating from 402 reviews, the highest volume we captured for any Mumbai electrical contractor. It states 16 years of experience and lists turnkey warehousing projects, commercial and industrial contracting, panels and data cabling. The scope reads generalist, so match it to job size.

Best suited for: smaller commercial and warehouse jobs where responsiveness and a long public review trail matter more than HT capability.

How to verify a licensed electrical contractor in Mumbai

Every credential in this article is self-stated, ours included. Verification takes about an hour:

1. Ask for the electrical contractor licence copy. Check the exact firm name, class and validity date against the licensed contractor list published by the Chief Electrical Inspector, Maharashtra. The name on the licence often differs from the trading name.

2. Ask for three completed projects comparable to yours in load and sector, with contactable references.

3. Ask which parts of the HT scope the firm self-performs and which it subcontracts. The answer changes who is actually on your site.

4. Ask what testing and commissioning documentation you receive at handover.

5. Get the quotation against a BOQ, not a lump sum, so scope changes are priced from a base you can audit.

A contractor who answers all five quickly is telling you something. So is one who does not.

Common questions about electrical contractors in Mumbai

1. How do I verify an electrical contractor's licence in Maharashtra?

   
   

   Ask the contractor for the licence copy, then match the firm name and licence number against the licensed contractor list published by the Chief Electrical Inspector, Maharashtra (ceimah.in). Check the validity date and the licence class, and confirm the registered name matches the entity named in your contract.

   
   

2. What is the difference between an electrical contractor and an electrician?
   

   An electrical contractor is a licensed firm authorised to execute and certify installation work, employing supervisors and wiremen under that licence. An electrician is an individual tradesperson. Industrial and commercial installations in Maharashtra require a licensed contractor, and utility connections require test reports that only licensed entities can issue.

   
   

3. Does an industrial project in Mumbai need an HT-licensed contractor?

   If your premises take supply at 11 kV, 22 kV or 33 kV, or the scope includes a substation, transformer or HT switchgear, then yes: the work must be executed by a contractor licensed for that voltage class, and the installation needs utility and electrical-inspector approvals before charging the power supply. LT-only fit-outs have a lower bar.

   
   

4. How many electrical contractors are there in Mumbai?

   
   

   More than most buyers expect. Justdial listed over 11,800 electrical contractors in Mumbai in August 2026, with over 1,750 under its industrial category, and Maharashtra's official licensed contractor list runs to 484 pages statewide. The practical shortlist for genuine HT industrial work is far smaller, which is what this article set out to map.

About this list

Compiled by Grade Electricals Pvt. Ltd., an Andheri East electrical contractor working in turnkey projects, HT/LT maintenance, exhibition power and liaisoning since 2004. We publish this list because we sit in these tender processes ourselves and know how little verifiable information reaches the buyer. It is reviewed monthly: ratings are re-captured, firm websites re-checked, and changes noted here with the review date. Found an error, or a contractor we should evaluate?
