Ulex Energy

Ulex Energy is a local, independent renewable energy company based in Swansea, serving homes and businesses across South Wales.

We specialise in solar PV, battery storage, EV charging and backup power systems. Every installation is designed around the property, energy usage and customer’s priorities—not simply supplied as a standard package. We provide clear forecasts of expected generation, savings and payback so customers can make an informed decision before committing.

Led by a Chartered Engineer and qualified electrician, our in-house team manages the complete process, including system design, technical surveys, DNO applications, installation, commissioning and aftercare.

Ulex Energy is MCS certified, TrustMark registered and a member of RECC. Our installations are backed by comprehensive manufacturer warranties and a 10-year insurance-backed workmanship guarantee.

Whether you want to reduce electricity bills, make better use of off-peak tariffs, protect your home during a power cut or move towards greater energy independence, we will design a practical system that meets your needs.
