Electrical Installation Company in Bangladesh

Last updated: 7 October 2026

An electrical installation company in Bangladesh designs, supplies, installs and commissions the electrical system of a factory or building, from the incoming HT or LT supply through panels, cables and distribution boards to lighting and earthing. Veritas delivers this complete scope and then tests and certifies the installation before it is energised for use.

Most electrical problems in factories and commercial buildings start at installation stage: undersized cables, loose terminations, missing earth connections, panels with no space for future load, or circuits that were never tested before being switched on. A competent installer removes those risks at source by following a proper design, using suitable materials and proving the finished work with recorded tests.

Veritas Technologies Ltd is a DIFE-enlisted engineering firm with offices in Dhaka and Chittagong. We handle the full chain from electrical design and load calculation to installation, testing and commissioning, so one team is responsible for the result. If you only need inspection and paperwork on an existing system, our electrical installation certificate and electrical wiring certificate pages are the detailed guides to those services.

What Does an Electrical Installation Company Do?

An electrical installation contractor turns an approved design into a safe, working power system. The job is broader than pulling cables: it includes checking that the design suits the actual site, coordinating with civil and mechanical trades, procuring equipment that matches the specification, installing it neatly and accessibly, and proving with measurements that every circuit is safe before handover.

For industrial clients the installation also has to be maintainable. Panels need labelled outgoing feeders, cable routes need to be traceable, and the as-built drawings must match what is on the wall so that future maintenance teams and auditors can work from them.

What Is Included in Our Installation Scope?

We take on complete projects or individual packages, depending on what the main contractor or owner needs.

• HT works: HT switchgear, HT cable laying and termination, and coordination with the sub-station supplier and the utility.
• LT distribution: main distribution board (MDB), sub-distribution boards (SDB), final distribution boards (DB) and changeover arrangements with generators.
• Cabling: cable tray, ladder and trunking installation, cable laying, glanding, lugging and termination for power and control circuits.
• Busbar trunking: busbar trunking system (BBT) runs for high-current risers and production floors.
• Earthing and bonding: earth electrodes, earth pits, main earthing terminal, protective conductors and equipotential bonding of metal services.
• Lighting and small power: luminaires for production halls, offices, stores and outdoor areas, sockets, emergency lighting circuits and exit signage supply.
• Power factor improvement (PFI): capacitor banks with automatic controllers, sized to the measured or calculated reactive load.
• Machine connections, motor feeders and control wiring for production equipment, compressors and pumps.

How Do We Deliver a Project from Design to Commissioning?

1. Site survey and collection of the load list, machinery layout and existing drawings.
2. Load calculation, single-line diagram, cable sizing and protection selection, or review of the consultant's design if one already exists.
3. Bill of quantities, material submittals and approval of panels, cables and accessories before purchase.
4. Installation of containment, earthing, panels and cabling in the agreed sequence with other trades.
5. Termination, labelling and tightening of connections to the specified torque where stated by the manufacturer.
6. Inspection and testing of each circuit while de-energised, then energisation and live functional tests.
7. Commissioning of PFI panels, changeovers, generator interfaces and protection settings.
8. Handover with test sheets, certificate, as-built drawings and a short briefing for the client's maintenance staff.

Where a separate consultant has designed the system, we follow that design and raise technical queries in writing rather than changing it on site.

Which Tests Are Carried Out Before Certification?

No installation should be energised for use until it has been inspected and tested. The tests below follow the verification approach of IEC 60364 and are recorded circuit by circuit. The table shows which tests apply to each part of a typical scope.

We carry out these measurements with calibrated instruments. For larger or older systems you can also book a stand-alone cable insulation resistance test or an earth resistance test.

Electrical Installations Certification in Bangladesh: How It Fits In

Electrical installations certification in Bangladesh is the step that turns a finished installation into a documented, verifiable asset. After testing, we issue a certificate that records the extent of the installation, the design basis, the test results and any limitations, signed by the engineer responsible.

Because we install and certify within one organisation, testing is planned from day one rather than added at the end. Test points are left accessible, circuit charts are prepared as the work progresses and defects are corrected before the certificate is issued.

Electrical wiring certificate company in Bangladesh for existing buildings

Not every client needs a new installation. Many factories approach us as an electrical wiring certificate company in Bangladesh because a buyer audit, insurer or landlord has asked for proof that existing wiring is safe. In that case we inspect, test and report on what is already there and list any remedial works. The detailed steps are on our electrical wiring certificate guide.

Electrical test certificate in Bangladesh for extensions and alterations

When a new production line, floor or panel is added, the new work and its connection to the existing system need testing. We issue an electrical test certificate in Bangladesh covering the addition and note any existing defects found at the interface, so responsibility is clear.

Which Standards Apply to Electrical Installation in Bangladesh?

The Bangladesh National Building Code (BNBC 2020) Part 8 covers building services, including electrical installations in buildings: supply arrangements, distribution, wiring, earthing and safety provisions. For detailed low-voltage practice and verification we follow the IEC 60364 series, which sets out requirements for the design, erection and verification of low-voltage installations.

Factories also have to satisfy the electrical safety expectations of the Bangladesh Labour Act and Rules as applied by DIFE, and many export-oriented units must meet buyer or alliance-derived electrical requirements. Where these apply, they are written into the project specification and checked during testing.

Who Needs a Professional Electrical Installation Contractor?

• Factory owners building new RMG, textile, pharmaceutical, food or light engineering units.
• Existing factories adding floors, machines, chillers or compressors that increase load.
• Developers of commercial buildings, shopping centres, hospitals and educational institutions.
• Owners who have received electrical findings from an audit and need corrective works completed and verified.
• Main contractors and EPC firms that need a specialist electrical package delivered to a specification.

What Do You Receive at Handover?

• Completed installation built to the approved drawings and specification.
• Inspection checklists and circuit-by-circuit test results.
• Electrical installation certificate signed by the responsible engineer.
• As-built single-line diagram, panel schedules and cable route drawings.
• Commissioning records for PFI, changeover and protection settings.
• Equipment data sheets and manufacturer manuals supplied with the materials.
• Recommendations for periodic inspection and maintenance.

What Does Electrical Installation Cost in Bangladesh?

Pricing depends on scope rather than floor area alone. The main factors are:

• Total connected load and whether the supply is HT or LT.
• Number, rating and type of panels, switchgear and PFI equipment.
• Cable sizes and lengths, containment type and installation height.
• Earthing, bonding and lightning protection requirements.
• Whether design, approvals coordination and certification are included.
• Working conditions: new build, live factory, night work or phased shutdowns.

Send us your drawings or load list for a quotation. If you are not sure what your existing system needs, start with an electrical safety assessment and we will scope the corrective work from its findings.
