What tariffs do Tulo Energy offer?
Tulo offers a range of tariffs that vary by region and meter type. Their main tariffs include:
3. What tariffs do Tulo Energy offer?
| Tariff Name | Type | Exit Fee | Notes |
|---|---|---|---|
| Vari-One | Variable | None | No fixed term, price can change with market. |
| Fixed July 25 | Fixed | Yes (amount varies) | Fixed for 12 months. Exit fee of £60 per fuel. |
- A variable tariff, known as “Vari-One” or generic standard variable, with no fixed term and typically no exit fees.
- A series of fixed-term tariffs, named by month (e.g., Fixed May 25, Fixed June 25), offering price certainty but with exit fees of £60 per fuel.
Tariffs can be viewed on Tulo’s live pricing portal by entering your postcode.
Smart meter support is fully integrated: installations are possible via web chat or email, and if a smart meter fails to send readings, users can submit manual reads through the online account.
Are Tulo Energy cheap?
To look at Tulo Energy’s pricing, we’ve used the estimated usage of a 3-bed house in the East Midlands.
Here’s how Tulo’s tariffs compare:
| Tariff Name | Annual Cost | Difference vs Ofgem Cap |
|---|---|---|
| Tulo Fixed 12 Months V2 | £1,604.00 | £170 cheaper |
| Tulo Vari-One | £1,652.00 | £122 cheaper |
| Standard Variable Tariff (SVT) | £1,774.00 | Same as price cap |
The Tulo Fixed 12 Months V2 offers the largest saving compared to the cap in this example, coming in about £170below. The Tulo Vari-One is also cheaper than the cap by around £122, while the Standard Variable Tariff matches the price cap.
The fixed option may appeal if you want price certainty for the next 12 months, although it does carry a £60 exit fee per fuel if you switch early. The variable tariffs have no exit fees, giving you the flexibility to move if prices drop, but rates can change with 10 days’ notice.
Tulo’s fixed and Vari-One tariffs are competitive against the current cap, especially for those seeking predictable or below-cap bills.
What do other reviews say?
- Trustpilot: As of mid-August 2025, Tulo holds a rating of 4.5 out of 5 based on approximately 650 customer reviews. Positive comments highlight “great switching experience”, “transparent pricing”, and “helpful support agents”. Some critical feedback mentions occasional login glitches or challenges in submitting meter readings via the app or website.
- Energy Ombudsman: Tulo is listed as an accepted supplier, meaning complaints not resolved within eight weeks (or that reach a deadlock stage) can be pursued through formal escalation. Tulo’s complaint process is outlined in its help centre, and it complies with Ombudsman requirements.
- General visibility: Tulo does not appear in Citizens Advice’s main star-rating table, as that list covers only suppliers with over 25,000 customers. Tulo might appear in smaller suppliers’ summaries or data tables, but they have not achieved the scale to enter the primary listing.
Overall, sentiment is positive regarding pricing, speed, and clarity, with mild usability concerns raised by a minority of users.
How green is Tulo’s energy?
Tulo publishes its fuel mix disclosure for the period 1 April 2023 to 31 March 2024:
| Source | Tulo (%) | UK Average (%) |
|---|---|---|
| Natural Gas | 67.9 | ~37 |
| Coal | 14.7 | ~1.8 |
| Nuclear | 10.6 | ~14 |
| Renewables | 0.2 | ~41 |
| Other | 6.6 | ~6 |
That means Tulo’s electricity is significantly based on fossil fuels, with a minimal renewable component.
The company does not appear to offer explicitly green electricity tariffs or renewable-backed products at this time, nor do they retire REGOs or make specific claims about investing in new green generation.
Customers seeking a high-renewables profile may therefore prefer suppliers with stronger green credentials, like Octopus Energy.
What is Tulo Energy’s customer service like?
Tulo offers support via email, web chat, and phone. The help centre suggests that chat and phone support are available Monday to Friday, from approximately 9 am to 5 pm. The online account remains available at all times for bill management, meter readings, or general enquiries.
Customer reviews frequently praise the quality of support agents, with many noting that responses are quick, friendly, and helpful.
Some users, however, report minor frustrations, particularly with login issues or trouble uploading meter readings through the app rather than their web account.
Still, the availability of Ombudsman escalation and publicly published contact routes shows Tulo meets industry requirements and provides a clear service channel hierarchy.
What is Tulo Energy’s website and app like?
Tulo provides an online portal and a mobile app for account management. The web interface allows you to get a quote, switch suppliers, submit reads, view statements, and change payment methods. Mobile app functionality covers similar core tasks like meter readings, billing overview, and payment management.
The app is available on both the App Store and Google Play Store. On the App Store, it has a high rating of 4.5 from 8 reviews. On the Google Play Store, however, it only has a score of 2.
User feedback indicates that the majority find the platform intuitive, especially for initial switching and regular billing.
A minority, however, have flagged intermittent login code failures, expired web sessions, or difficulty submitting readings via the app (though these issues are often resolved via the web portal or support contact).

Who is Tulo best for?
Tulo is a solid match for:
- Customers seeking dual-fuel supply with clear, competitive pricing and no hidden charges.
- Households that are comfortable using digital platforms for self-service management and switching.
- Customers who want the option to choose between variable and fixed tariffs, with price transparency.
Tulo may be less appealing for:

- Users who frequently rely on mobile apps and expect high-quality UX without occasional login hiccups.
- Those seeking large brands with broad coverage or loyalty incentives.
What’s changed since early 2024?
Since 2024, Tulo has expanded its range of fixed-term options, with multiple fixed months available for selection.

They have not launched green products or shifted their fuel mix significantly in that interval.

Verdict: Is Tulo Energy a good choice in 2025?
If you are looking for a no-nonsense supplier offering competitive prices, transparent terms, and digital ease, Tulo is definitely worth considering, especially for dual-fuel usage.
Their recent customer feedback affirms strong performance in switching and support. The key trade-off is environmental: if you prioritise green energy content, you may want to explore suppliers with a higher renewables share or renewable-backed tariffs.
Always compare a live Tulo quote with your postcode-specific price cap and competitor offers before committing to switching.
