Electrical Design & Installation for Homes, Businesses, and New Builds in Thailand
Residential, Commercial, and Industrial Electrical Contracting — Designed and Built by Kunini
Kunini is a professional electrical design and installation contractor serving residential, commercial, and industrial clients across Thailand. We work on new builds, full renovations, and complex electrical upgrades — designing systems from the ground up and seeing them through to a fully tested, commissioned installation.
We are not a call-out maintenance firm. We don’t fix sockets or replace lightbulbs. What we do is design and build electrical systems that work properly from day one — and for clients building or renovating with solar energy in mind, we do that as a fully integrated package.
If you are planning a new build, a major renovation, or a significant electrical upgrade in Thailand, Kunini is the contractor to speak to first.
Our Approach — Design First, Then Build
Every Kunini electrical project starts with design. Before a single cable is run or a single component is specified, our engineers sit down with you to understand the property, the load requirements, the intended use, and your long-term plans — including whether solar energy is part of the picture.
That design-first approach is what separates a properly engineered electrical system from one that simply passes inspection. It means your switchgear is correctly sized, your distribution is logical, your circuits are future-proof, and your system is ready for whatever you add next — whether that’s additional plant, EV charging, or a solar rooftop.
We then manage the full installation, working to international standards, coordinating directly with the PEA or MEA for grid connections, and handling all compliance documentation and commissioning. You receive a fully tested, certified system — not just a bill of materials and a handshake.
Solar-Ready Electrical Design for New Builds
One of the most common and costly mistakes in new construction in Thailand is treating the electrical system and the solar system as two separate projects. They are not. A building designed with solar in mind from the outset can have its switchgear, distribution boards, inverter connections, and load circuits laid out to work together seamlessly — from day one.
Kunini is uniquely positioned to deliver this. As both a licensed electrical contractor and a solar EPC, our engineers design the electrical system and the solar or hybrid system as one integrated whole. The inverter location, the DB configuration, the circuit priorities, the battery connection points, and the Zero Export or grid connection compliance are all resolved at the design stage — not retrofitted after the fact.
For developers, hotel owners, or homeowners building new properties in Thailand, this integrated approach saves time, avoids expensive rework, and results in a system that genuinely performs as intended.
Residential Electrical
Kunini provides full electrical design and installation services for residential new builds and renovations throughout Thailand. Whether you are building a private villa, a pool house, or a multi-unit residential development, our team designs and installs your complete electrical system — from the main supply connection through to final sockets, lighting, and smart controls.
For homeowners who are building or renovating with solar in mind, we design the electrical system to accommodate your solar inverter, battery storage, and EV charging from the outset, so nothing needs to be reworked later.
Commercial Electrical
Our commercial electrical division serves hotels, resorts, retail centres, office buildings, restaurants, and mixed-use developments across Thailand. Commercial electrical systems are more complex than residential — higher loads, three-phase supply, multiple distribution boards, back-up power requirements, and increasingly, EV charging infrastructure for guests and staff.
Kunini designs and installs the full scope. We are experienced in coordinating electrical works alongside other trades on active construction sites, and in phasing installations to minimise disruption to ongoing operations during renovation projects.
Industrial Electrical
For factories, warehouses, and industrial facilities, Kunini provides design and installation of high-capacity electrical systems, including three-phase power distribution, industrial switchgear, motor control panels, and compliance with ERC and PEA or MEA industrial connection requirements. We also design and integrate solar generation systems for industrial clients seeking to offset significant daytime electricity consumption.
Our Services
Electrical Wiring and Installations
Full design and installation of single and three-phase electrical systems for new builds and renovations. All work is carried out to Thai regulatory standards and international best practice, with full testing and commissioning before handover.
Power Distribution, Switchgear, and Distribution Boards
Design and installation of main distribution boards, sub-distribution panels, circuit breakers, busbar systems, and metering equipment. We also carry out standalone switchgear and DB upgrades for existing installations that require additional capacity or reconfiguration.
Switchgear Operations and Maintenance
For clients who require ongoing switchgear maintenance following installation, Kunini provides structured O&M programmes covering inspection, testing, cleaning, and preventative maintenance of switchgear and distribution equipment.
Lighting Design and Installation
Energy-efficient LED lighting design and installation for residential, commercial, and industrial spaces. We work with lighting designers and architects on complex projects, and specify and install lighting systems independently for new build and renovation work.
EV Charging Infrastructure
Design and installation of EV charging points for residential properties, hotel car parks, commercial developments, and industrial sites. We specify, supply, and install charging equipment and ensure your electrical supply and distribution are correctly rated to support current and future EV charging load — including integration with solar and battery storage where applicable.
Generator Connections and Back-up Power
Design and installation of generator connections, automatic transfer switches (ATS), and back-up power systems for residential, commercial, and industrial properties. We ensure your generator installation is correctly integrated with your main distribution system and complies with all relevant safety standards.
Electrical Safety Inspections
Thorough electrical safety inspections for commercial and industrial properties, identifying compliance issues, potential hazards, and areas requiring upgrade. We provide a written inspection report and, where required, can carry out the necessary remedial works.
Renovation Electrical Works
For significant renovation projects, Kunini can assess the existing electrical installation, design any required upgrades or extensions, and carry out the full installation scope. We do not carry out minor repairs or call-out maintenance — but if you are undertaking a meaningful renovation, we are the right team to involve from the design stage.
Why Kunini
Kunini has been working as a licensed electrical contractor in Thailand since 2002. Our electrical division predates our solar business — and the depth of electrical engineering expertise that comes with over two decades of contracting is what makes our solar installations as reliable as they are.
Every project is led by our own in-house engineers. Where additional labour is required on larger installations, we work with approved contractors under the direct supervision of a Kunini engineer. All design work, testing, commissioning, and compliance documentation remain entirely within our own teams.
We manage all permit applications, ERC compliance documentation, and PEA or MEA connection approvals required for your installation. You do not need to deal with government offices or utility paperwork — we handle it from start to finish.
And because we are both a licensed electrical contractor and a solar EPC, we are the only contractor in the region who can design and deliver your entire energy system — electrical, solar, battery, and EV charging — under one roof, with one point of contact, and one responsible engineering team.
