UW Partners in and around are people just like you, who earn an extra income by introducing others to UW and helping them sign up as customers. They also help people to become a UW Partner and start earning an income by recommending UW to their friends and family.
Yes, of course – over 1,386,585 customers and 70,000 UW Partners already do. We’re also regulated by the energy regulator Ofgem, the telecoms regulator Ofcom, and the Financial Conduct Authority. We’ve been doing business for nearly three decades and are listed on the London Stock Exchange, which means we’re one of the UK’s largest publicly-owned companies.
Your gas and electricity energy services in will go live between two and five working days. We’ll keep you updated on any progress during this time.
Yes – switching energy suppliers in is a simple process. All you need to do is get a quote now to get started; then, we’ll contact your old provider on your behalf and get your services switched over for you. It’s that easy.
No. We work hard to ensure a seamless switching process between energy providers for our customers in so we can guarantee that there’ll be no disruption to your services.
No – in 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 billing you. So you won’t pay for the same energy twice. Your old supplier will then arrange to send you a final invoice. We recommend leaving your Direct Debit in place until that invoice has been paid.
Smart meters are advanced devices that measure and record electricity and gas consumption in near real-time. Smart meters automatically send us your electricity and gas meter readings through secure wireless networks, so you don’t have to.
