Treating you fairly

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 average of the cheapest variable tariffs available from the 'Big 6' suppliers, based on payment by direct debit for typical household consumption of 2,900 kWh electricity and 12,000kWh gas. The 'Big 6' are SSE, EDF, Scottish Power, E.ON, npower, and British Gas. When any changes to competitors' relevant variable tariffs are announced, we will adjust our own tariffs to ensure they comply with our Guarantee within a maximum of 90 days. Our Energy Price Guarantee does not apply to our Double Gold 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.

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 install and service boilers

Get a 20% discount plus free installation on a choice of Which? recommended boilers, all for as little as £30 per month* and with no upfront deposit.

The legal bit

Your boiler will be supplied and installed by Glow Green Limited, a Utility Warehouse group company.

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.
