About us

Hello, we’re OneSelect

Although OneSelect is new to the UK market, its parent company has extensive energy market experience having launched Energieflex in the Netherlands in 2014. Energieflex is now a major supplier to the Dutch market and was the first to offer pre-paid billing, smart meters and 24 hour switching.

OneSelect’s business is based on 4 simple principles:


We aim to be fair and transparent by offering great energy prices and dealing with customers in a straightforward and honest way.


We don’t believe energy should be complicated. With OneSelect you get low priced energy fixed for 12 months. There are no exit fees, no hidden costs and no unpredictable bills.


Because using less energy helps to reduce bills and environmental impact we help you stay in control of your consumption with advice and personalised usage data.


With innovative, simple tariffs we’ll make it easier for you to pay less for your gas and electricity. Over time we’ll apply the same thinking to other services like broadband, mobile, TV and insurance.
What we are planning for the future

At OneSelect we believe consumers deserve a better deal, but this doesn’t have to stop with your energy bills. Now we’re looking at transforming expensive, complicated services such as broadband, mobile and insurance with innovative products based around a simple, straightforward competitively priced tariff.
