Tulo Energy Review: Is This New Supplier the Right Choice for Your Home?
The UK energy market is constantly evolving, with new suppliers emerging to challenge the established giants. One such name gaining attention is Tulo Energy. Promising competitive pricing, a straightforward digital experience, and a customer-focused approach, Tulo aims to simplify how we manage our gas and electricity.
But does it deliver on these promises? In this comprehensive review, we will explore everything you need to know about Tulo Energy, from its tariff structures and pricing to its customer service reputation and environmental credentials.
1. Who Are Tulo Energy?
Tulo Energy is a newer, independent energy supplier operating across England, Scotland, and Wales. They function under the legal trading name Square1 Energy Limited and hold the necessary gas and electricity supply licences from the UK's energy regulator, Ofgem. The company's registered office is in Worcester, Worcestershire, and it was incorporated in mid-2023, making it a relatively young entrant compared to many established names in the market.
This confirms their legitimacy and means they must adhere to the strict rules governing the industry. Furthermore, Tulo Energy is registered with the Energy Ombudsman, providing customers with a crucial, independent route for escalating complaints if they cannot be resolved directly. This offers an essential layer of consumer protection and peace of mind.
2. An In-depth Look at Tulo Energy Tariffs
Tulo focuses on providing simple and transparent tariff options to suit different household needs. Their main offerings typically fall into two categories: fixed-rate and variable-rate tariffs, which can be viewed and compared on their website by entering your postcode and meter type.
Fixed-Rate Tariffs
For households that prioritise budget certainty, Tulo offers fixed-term tariffs. These plans lock in your unit price for electricity and gas for a set period, usually 12 months. This protects you from wholesale market price hikes during the contract term, making it easier to forecast your annual energy spend.
Tulo's fixed tariffs are typically refreshed and renamed on a rolling basis (for example, you may see deals labelled by the month and year they launched). This means the specific fixed-rate offer available to you will depend on when you get your quote, so it's worth checking the live pricing portal for the most current options.
It is important to note that these tariffs often come with an exit fee, typically around £60 per fuel, if you decide to leave before the contract ends. This is a standard practice that compensates the supplier for purchasing your energy in advance. Tulo states that any applicable exit fees are clearly displayed at the point of sign-up and within your tariff documentation.
Variable-Rate Tariffs
If you prefer flexibility over a long-term commitment, Tulo's variable tariffs could be a suitable option. The most prominent is the 'Vari-One' tariff. With this plan, your unit rates can rise or fall in line with wholesale energy market fluctuations, and Tulo can adjust pricing with around 10 days' notice to customers.
While this means you could benefit from lower bills if market prices drop, you are also exposed to potential price increases. However, these tariffs are protected by the Ofgem energy price cap, which limits the maximum rate suppliers can charge. A key advantage is that variable tariffs generally do not have exit fees, allowing you to switch to a different deal or supplier at any time.
Here is a summary of the typical tariff types you might find:
| Tariff Type | Best For | Exit Fees | Price Stability |
|---|---|---|---|
| Fixed-Rate (e.g., 12 months) | Customers seeking predictable bills and protection from price rises. | Usually apply (around £60 per fuel) | High (for the duration of the contract) |
| Variable-Rate (e.g., Vari-One) | Customers wanting flexibility and the potential to benefit from falling prices. | Typically none | Low (prices can change with notice) |
3. How Competitive Are Tulo Energy's Prices?
For many, the bottom line is cost. To assess Tulo's competitiveness, we can compare their typical offers against the Ofgem price cap, which reflects the average price for a standard variable tariff and is updated every three months.
It's worth noting that the price cap has moved significantly during 2026. After sitting at around £1,641 a year for a typical dual-fuel household paying by Direct Debit between April and June 2026, Ofgem confirmed a 13% increase from 1 July 2026, taking the typical annual bill to roughly £1,862 (or around £1,663 under Ofgem's revised, lower typical consumption assumptions). This rise has largely been driven by higher wholesale gas prices.
Based on estimates for a medium-usage household, Tulo's tariffs have often been priced favourably against this benchmark.
Example Price Comparison (Illustrative Only)
| Tariff | Estimated Annual Cost | Comparison vs. Ofgem Price Cap |
|---|---|---|
| Tulo Fixed 12-Month Tariff | £1,690 | Below the new cap level |
| Tulo Vari-One Tariff | £1,740 | Below the new cap level |
| Ofgem Price Cap (SVT, from July 2026) | £1,862 | Baseline |
Note: These figures are for illustrative purposes only and will vary based on your location, usage, meter type, and the time of comparison. Always get a personalised quote for an accurate price, particularly as the price cap is reviewed every quarter and the next change (for October to December 2026) is due to be announced by late August 2026.
As the table shows, both Tulo's fixed and variable options can offer worthwhile savings compared to sitting on a price-capped standard tariff, especially during periods when the cap is rising. This pricing strategy remains a key part of their appeal as a challenger brand, with several customer reviews specifically praising their per-unit rates as among the cheapest available.
4. The Digital Experience: Website and Mobile App
Tulo Energy positions itself as a digital-first supplier, encouraging customers to manage their accounts online or through their mobile app. The online portal allows you to perform essential tasks such as submitting meter readings, viewing bills and statements, and managing payments. Smart meter installations can also be arranged via web chat or email, and if a smart meter fails to send automatic readings, customers can submit manual reads through the app or website.
The Tulo Energy app is available on both the Apple App Store and Google Play Store. While it covers core functionalities, user feedback appears mixed. Many customers describe the app as simple and easy to use for entering readings and tracking usage, with some specifically noting it avoids unnecessary bells and whistles. However, others have reported technical issues, including login problems following app updates, two-factor authentication steps that feel cumbersome for a simple task like submitting a reading, and occasional smart meter compatibility issues that mean readings have to be submitted manually. In most cases, these issues can be resolved by using the main website instead or by contacting customer support directly.
5. Customer Service and Support
Feedback on Tulo's customer service is generally very positive. According to their Trustpilot page, Tulo holds an 'Excellent' rating of around 4.5 to 4.6 out of 5, based on a growing pool of customer reviews that has expanded from a few hundred to well over 700 over the past year or so.
Commonly praised aspects include:
- A fast and seamless switching experience, with many customers reporting the move to Tulo happened with little to no hassle.
- Transparent pricing with no unexpected charges, and unit rates that several reviewers describe as among the cheapest they've found.
- Responsive and friendly support staff via phone and email, with individual support agents frequently singled out by name for going above and beyond, including in sensitive situations such as bereavement-related account changes.
- Straightforward handling of billing queries, including refunds of credit balances and adjustments to direct debit amounts.
However, some negative feedback persists around app and smart meter usability issues, and a small number of reviewers have reported billing discrepancies or difficulties getting timely responses during busier periods. As with any supplier, it's worth keeping an eye on your account balance and meter readings to catch any discrepancies early.

6. How Green Is Tulo Energy?
In an era of increasing climate awareness, a supplier's environmental impact is a major consideration for many. While some marketing materials may suggest a focus on sustainability and customer-driven innovation, Tulo Energy's official fuel mix disclosure tells a different story.
Here is a breakdown of their electricity sources for 2023-2024 compared to the UK average:
| Fuel Source | Tulo Energy (%) | UK Average (%) |
|---|---|---|
| Renewables | 0.2% | ~41% |
| Natural Gas | 67.9% | ~37% |
| Coal | 14.7% | ~1.8% |
| Nuclear | 10.6% | ~14% |
| Other | 6.6% | ~6% |
The data clearly shows that Tulo's electricity is overwhelmingly generated from fossil fuels, particularly natural gas and coal, with a renewable component that is negligible compared to the national average. At present, they do not offer specific "green" or 100% renewable electricity tariffs. As fuel mix disclosures are typically updated annually, it's worth checking Tulo's most recent published figures directly if this is an important factor for you, as the picture can shift from year to year.
For environmentally conscious consumers, this is a significant drawback. If supporting renewable energy is a priority, you would be better served by suppliers with stronger green credentials.
7. Our Verdict: Should You Switch to Tulo Energy?
Tulo Energy presents a compelling case for a specific type of customer. If your primary motivation for switching is to secure a competitively priced dual-fuel tariff and you are comfortable managing your account online, Tulo is an excellent contender. Their pricing often undercuts the Ofgem price cap, their switching process is praised for its efficiency, and their customer support is consistently well-regarded, as reflected in their strong and growing Trustpilot rating.
However, the supplier may be less suitable for others. Those who prioritise renewable energy will find Tulo's reliance on fossil fuels a major disqualifier. Similarly, customers who prefer a polished, feature-rich mobile app experience, or households with smart meters that need full two-way compatibility, may encounter some frustration.
Pros and Cons of Tulo Energy
Pros:
- Highly competitive pricing that often beats the price cap, even as the cap itself rises.
- Transparent tariff structures with clearly displayed exit fees and terms.
- Simple and efficient online switching process, frequently praised by customers.
- Strong and growing positive customer feedback on Trustpilot, with an 'Excellent' rating.
- Regulated by Ofgem and part of the Energy Ombudsman scheme.
Cons:
- Extremely low level of renewable energy in its fuel mix.
- The mobile app has received mixed reviews, with some smart meter compatibility and login issues.
- As a smaller, newer supplier, it lacks the brand recognition or additional perks of larger companies.
- Exit fees apply to their fixed-rate deals.
Ultimately, Tulo Energy is a solid, no-frills choice for the cost-conscious consumer, and one that appears to be building a strong reputation for customer service as it grows. Given that the energy price cap has just risen and is reviewed again for October 2026, now is a particularly good time to check whether a fixed deal could offer better protection against further increases. Before making a decision, we recommend getting a direct quote from their website to see how their prices stack up for your specific home and usage.
