Tulo Energy Review (September 2026)
Overview
Tulo Energy has strong Trustpilot reviews, but a lack of fixed tariffs and independent service data makes it difficult to judge against other suppliers.
Who are Tulo Energy?
Tulo Energy is an independent domestic energy supplier in the UK. Square1 Energy Limited, which trades as Tulo Energy, was incorporated in 2017 and began registering its first customers in 2019. It is owned by Tulo Group Holdings Limited. It is a smaller supplier building its customer base in the UK energy market.[1]
What sets Tulo Energy apart is its focus on a simple digital experience and fast, UK-based support. Customers can manage their accounts, submit meter readings, and view bills using an online portal or mobile app. For direct help, the supplier runs a customer service team that aims to answer calls in about 20 seconds and resolve support tickets within an hour.

Customer reviews
Tulo Energy holds a Trustpilot rating of 4.6 out of 5, based on 822 reviews. Overall sentiment leans positive, with 78% of reviewers awarding five stars and 4% leaving a one-star score.
Feedback indicates that users are generally satisfied with the support team, frequently noting prompt responses to queries. Reviewers also highlight a straightforward setup process and report that the billing system functions reliably.
Apps
Tulo Energy provides mobile apps for both iOS and Android devices, though the current rating samples are too small for a definitive assessment. The iOS version scores 5.0 out of 5 from just two ratings, while the Android app holds a 3.1 out of 5 from eight ratings across more than 1,000 installs.
Development activity varies between the platforms. The iOS app shows recent maintenance, with three updates in the last 90 days, including a release that added 'Smart Insights' to the account tab. Conversely, the Android application has not received an update in nearly a year.
Service and support
As a relatively new and smaller supplier, Tulo Energy does not yet feature in the Citizens Advice league table or the Which? annual energy survey. Consequently, there is no independent data available regarding its complaint handling, call centre wait times, or email responsiveness.
Complaints performance
Complaint figures are withheld from this repaired draft because no source URL was supplied for independent verification.
Green energy
Tulo Energy supplies electricity that is mostly generated from fossil fuels. According to its fuel mix data for 2024 to 2025, natural gas makes up 74.7% of its supply, while coal accounts for 14.8%. Only 0.3% of the electricity it supplies comes from renewable sources, which is much lower than the UK average.
The supplier supports the Smart Export Guarantee scheme. This lets customers with solar panels sell any extra electricity they generate back to the national grid.
Verdict
Tulo Energy has strong Trustpilot reviews, but a lack of fixed tariffs and independent service data makes it difficult to judge against other suppliers.
Tulo Energy demonstrates positive early indicators through its Trustpilot feedback, where users note responsive support and clear billing practices. However, the absence of fixed tariffs in our pricing data and a lack of independent service metrics make it difficult to form a complete picture of its overall performance.
The supplier may suit households seeking a flexible variable tariff who are encouraged by strong early customer reviews. Conversely, those who require the price certainty of a fixed-rate deal, rely heavily on established mobile apps, or prefer a provider with proven independent service scores may need to consider alternatives.

Hi, I'm Rob, and I run Energy-Review.co.uk. I initially started this project in 2018 when I was looking to switch energy suppliers and found there wasn't a website that provided simple, data-backed reviews on all the suppliers available. Since then, I have spent a lot of time (too much, some may say!) looking at all publicly available data about each supplier and writing reviews using this information. These reviews are updated as regularly as possible, and any data is backed up by a source where necessary. I have also started writing guides on various energy-related topics, which hopefully you will find useful. If you find any issues, please use our contact form to let us know.
