Tulo Energy is a small independent UK energy supplier built around three principles: simplicity, affordability and honesty. It keeps things simple, with one main variable tariff, no exit fees, and UK-based customer service by phone, email and live chat.
Tulo Energy is the trading name of Square1 Energy Ltd, which has been supplying homes since 2019 and later rebranded as Tulo.
Tulo is a small supplier that competes mainly on price, with a single variable tariff and no exit fees. Its Trustpilot reviews are positive, but it is too small to feature in the Which? or Citizens Advice rankings, so compare prices and service carefully before you switch.

Tulo Energy scores 4.6 out of 5 on Trustpilot from around 820 reviews, with 78% of reviewers giving five stars. Customers often mention competitive prices and helpful customer service.
Its app is rated less well, although from only a handful of ratings.
Why no Which? or Citizens Advice score? Both organisations only rank suppliers above a certain size. Tulo is too small to be included, so Trustpilot reviews are the main guide to its customer service.
Any electricity we use is generated from a combination of different fuels such as gas, nuclear, coal and renewable sources (wind, hydro and the sun). The proportion of each fuel a supplier buys makes up its fuel mix.
Tulo doesn't sell renewable electricity. Its most recent fuel mix disclosure shows that almost all of its electricity came from fossil fuels, mainly natural gas. If green energy matters to you, see our guide to green energy tariffs.
Tulo may suit you if you want a simple variable tariff with no exit fees, and its prices come out well for your postcode. Its Trustpilot reviews are positive, and you can leave at any time without a penalty.
Bear in mind that it is a small supplier with limited independent data on its service, it doesn't offer fixed, green or specialist tariffs, and its electricity isn't renewable.
As always, compare prices using your own postcode and usage before you switch.
