I am a part-time mobile hairdresser and live in Caerphilly borough. I started UW four and a half years ago to have a better work life balance, earn a bit extra, and build my pension pot. It is one of the best decisions I have ever made. Not only do I do all of the above, I also get to help people save or make money. Especially in this current climate, to see the relief on someone's face when you have saved them hundreds of pounds a year is priceless. Knowing we can make a difference to so many people is huge. Reviews are free, with no obligation. I just show you the savings and leave it up to you to decide what you do. It's worth 30 minutes of your time for sure!

Barry

It has allowed me to assist my clients in buying their first home or moving house by providing all the necessary services in a single app. Having been self-employed for many years, I have learned the value of helping others. Call me if you'd like to see how much money you could save as a customer. With my ongoing full support, I can also show you the benefits of starting your own UW business. Sport is my passion, I play hockey and golf; however, my favourite pastime is spending time with my family and friends.

Aberdare

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.
