Full electrical installations for commercial and industrial premises — new builds, refurbishments, and complete fit-outs. EIC approved, BS 7671 compliant, delivered UK-wide.
Oleco provides comprehensive commercial electrical installation services for businesses across the United Kingdom. Whether you are developing a new-build office complex, refurbishing a high-street retail unit, or fitting out a hotel or restaurant, our team delivers electrical systems that are safe, efficient, and designed for the specific demands of your operation.
As an EIC Approved Contractor, every installation we undertake meets the highest standards of workmanship, safety, and regulatory compliance. We work to BS 7671 (the IET Wiring Regulations) and Part P of the Building Regulations, ensuring your premises are fully compliant from day one.
Our commercial electrical installation services cover a broad spectrum of premises types. Each environment has its own requirements — from power density and lighting design to data infrastructure and emergency systems — and we tailor every installation accordingly.
We are equally experienced in new-build projects and refurbishment work. For new builds, we work from architectural drawings and specifications to design and install complete electrical systems from first fix through to commissioning and handover. For refurbishments, we assess existing infrastructure, identify what can be retained and what needs replacing, and deliver a solution that brings the premises up to current standards without unnecessary disruption.
Our work on the Midland Hotel in Conwy is a prime example of our refurbishment capability — a project that required sensitive integration of modern electrical systems within a characterful hospitality environment. The result was a sophisticated lighting scheme that enhanced the guest experience while meeting all current safety standards.
For industrial clients, we deliver electrical installations that support production environments and complex operational requirements. Our long-standing relationship with MOWI Group, the global salmon farming and processing company, demonstrates our ability to work within demanding industrial settings — installing power and control systems across multiple sites throughout the UK.
Industrial installations demand a different approach: understanding production workflows, working around live operations, and delivering systems that are robust enough for continuous use. Our team brings that expertise to every project.
Regulatory compliance is not an afterthought — it is integral to how we work. Every commercial electrical installation is designed and delivered in accordance with:
On completion, all installations are fully tested, certified, and documented. We provide Electrical Installation Certificates (EICs) and comprehensive as-built documentation, giving you and your insurers complete confidence in the work.
Every project begins with a detailed site survey and consultation. We take the time to understand your operational requirements, timelines, and budget before producing a comprehensive proposal. Throughout the project, you have a dedicated point of contact and regular progress updates. We coordinate effectively with main contractors, architects, and other trades to ensure seamless delivery.
Oleco is based in Menai Bridge, Anglesey, and delivers commercial electrical installations across North Wales, the North West, and the wider UK. Whether your project is local or national, we have the infrastructure and experience to deliver.
