It's fun and I choose my own hours. And I love saving people money and helping them making money. My girlfriend introduced me to the business so it's great working alongside her. I couldn't imagine working eight hours a day.

Due to struggling with childcare while the children were small, I started UW to allow me to be a full-time parent whilst also earning an income from home. After more than 8 years as a customer and partner, I am able to spend time with my children and help other families do the same. There’s nothing exciting about paying bills, which is why we help you with the boring stuff and make it fun and easy. We live in a small village in South Wales and have helped hundreds of families reduce their monthly spend and have more time with loved ones.

Your energy services will go live between two and five working days. We'll keep you updated on any progress during this time.
No, we'll contact your energy provider to let them know about your move.
After a few weeks, we'll ask you for meter readings, at which point we'll start billing you for your energy, and your current supplier will stop (so you won't pay for the same energy twice). Your old supplier will then arrange to send you a final invoice.
