Get award-winning, UK-based customer services, great value and peace of mind with our energy.

We supply
green energy

Our green fixed tariff means new customers who take all of our services can power their homes with 100% renewable electricity.


We'll beat the Ofgem "fair price" calculation by up to 5% and we promise to keep them lower than the price cap for as long as you remain a customer.*

Treating you

Whether you’re new to UW, or have been with us for years, everyone gets the same great value.

The legal bit

*Savings and Guarantee are compared to the Ofgem price cap level for default energy tariffs based on payment by direct debit for typical household consumption of 2,900 kWh electricity and 12,000 kWh gas. When any changes to the Ofgem price cap level are made, we will adjust our own tariffs to ensure they comply with our Guarantee for the date the new price cap level is introduced. Our Energy Price Guarantee does not apply to our Green Fixed tariff.

Save with a smart meter

Smart meters send your readings to us automatically, so you'll never have to worry about estimated bills again.

How long will my switch take?

We’ll work hard to ensure your switch goes as quickly as possible and within 21 days. We’ll keep you updated of progress during this time.

Do I need to contact my current supplier?

Don't worry - we’ll contact them to let them know about your move. 

In a few weeks time 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 that you never pay for the same energy twice). Your old supplier will then arrange to send out a final invoice to you. 

What happens if I already have a smart meter?

We use first generation smart meters made by the company Secure. Other suppliers who also use them include Utilita, Ovo, E.On and Octopus. 

If you have a Secure smart meter, we will continue to use this in smart mode so nothing will change. 

If you have a first generation smart meter made by anyone else, unfortunately it won’t currently work with us in smart mode, so you'll need to give us meter readings.  

If you have a second generation smart meter, then this will transfer to us with all its smart benefits intact and we’ll start communicating with it to collect your accurate readings.
