We are pleased to announce that Omni3 Limited is now an endorsed Which? Trusted Trader, endorsed on 24 September 2026 — independently assessed and endorsed by one of the UK's most recognised consumer advocacy organisations. This is a significant step for us and one we believe matters to the homeowners and businesses who choose us for electrical, solar PV, battery storage and EV charging work across West Sussex and the South East.
What Which? Trusted Traders means for you
Which? Trusted Traders is an endorsement scheme run by Which?, the UK's consumer champion. Before a business receives endorsement, it must pass a thorough independent assessment covering trading history, business practices, customer service standards, insurance and qualifications. It is not simply a membership programme — businesses are assessed before they can display the Which? Trusted Trader mark.
For our customers, that assessment means an additional layer of reassurance. When you choose Omni3 as your trusted electrician in West Sussex, your solar PV installer or your EV charger specialist, you have the confidence that an independent organisation has already done part of the vetting for you.
As a Which? Trusted Trader, Omni3 also operates under the Which? Trusted Traders Code of Conduct, which sets out what customers can expect in terms of workmanship, communication, transparent pricing, and complaint handling. Where a complaint cannot be resolved and both parties agree deadlock has been reached, eligible customers may be able to refer it to the Which? Trusted Traders Alternative Dispute Resolution service (ADR): 02922 670 040.
Our focus: professional workmanship and honest advice
Omni3 has always operated on straightforward principles: qualified engineers, proper certification, clear quotations and no pressure tactics. Every installation we carry out — whether solar panels on a residential rooftop, a battery storage system, commercial EV charging infrastructure, or electrical testing and certification — is completed to the appropriate standard and documented for the customer's records.
We believe customers deserve accurate information before making a decision. That means explaining what a system will realistically do, what it will cost, how long it will take, and what happens afterwards. We do not chase volume at the expense of quality, and we do not make claims we cannot support. The Which? Trusted Trader assessment reflects the way we already work.
Our services: electrical, solar, battery storage and EV charging
Omni3 is a multi-discipline electrical and renewable energy contractor based in Pulborough, West Sussex. Our engineers are qualified and certified across a broad range of services, meaning most properties only need one contractor rather than several.
- Solar PV installation — residential and commercial solar panel systems, designed and installed by our MCS certified team. If you are looking for a trusted solar installer in West Sussex, our engineers carry out a full site survey before any design work begins.
- Battery storage — home and commercial battery storage installation, with or without solar. Our battery storage installer team works with leading systems including EcoFlow, Sigenergy and SolaX, sized to suit your property and energy use.
- EV charger installation — domestic and commercial EV charging points, installed by our OZEV-approved EV charger installer team. We work with a range of charger brands and handle all relevant paperwork.
- Electrical contracting — as a trusted electrician serving West Sussex and the wider South East, we carry out domestic and commercial electrical installations, testing, inspection and certification (EICR), consumer unit upgrades, and more.
