Ecotricity: A Deep Dive into the UK's Original Green Energy Supplier

In an era where environmental consciousness is paramount, UK consumers are increasingly looking for energy suppliers that do more than just power their homes. They want a provider whose values align with their own. Ecotricity, a pioneer in the green energy movement, has been championing this cause since its inception.

Based in the heart of Gloucestershire, Ecotricity was established by green entrepreneur Dale Vince with a mission that extends beyond simply supplying power. This article explores the company's unique approach, its range of tariffs, its customer service reputation, and what truly sets it apart in the crowded UK energy market.

1. Who is Ecotricity? More Than Just a Supplier

Founded in 1995, Ecotricity holds the title of Britain's very first green electricity company. From the outset, its philosophy has been to challenge the status quo of the fossil fuel-dominated energy industry. The company is responsible for building the UK's first megawatt-scale windmill and has continued to innovate with grid-scale solar parks.

The company operates on a unique 'bills into mills' principle. This means it channels revenue from customer payments directly into researching and constructing new renewable energy sources. This model funds everything from maintaining its network of wind and solar farms to developing cutting-edge solutions like green gasmills, which aim to produce sustainable gas from grass. By choosing Ecotricity, customers are actively investing in the future of Britain's green energy infrastructure.

2. Understanding Ecotricity's Energy Tariffs

Ecotricity aims to keep its tariff structure straightforward, offering a few clear options for different types of households. As of mid-2024, their primary offerings are:

It is worth noting that, as of early 2025, Ecotricity applies an exit fee of £100 per fuel for customers who leave a fixed tariff before the end of their contract term.

3. The Ecotricity Price Cap Exemption Explained

In a move that sets it apart from almost every other supplier, Ecotricity holds a permanent exemption from the energy price cap for its standard variable tariff (SVT). This exemption has been granted by the regulator, Ofgem, in recognition of the company's substantial and ongoing investment in building new green energy infrastructure.

What does this mean for customers? It allows Ecotricity to set the price of its 'Green Electricity/Gas' SVT above the level of the national price cap. This is conditional on the basis that customers have made an active choice to be on this specific tariff, understanding that their higher payments are directly contributing to the development of new renewable projects across the UK.

4. What Are Ecotricity's Green Credentials?

Ecotricity's commitment to sustainability is its core identity. The company's electricity supply is 100% green and is also certified by The Vegan Society, as it is generated without involving animal by-products.

Unlike many suppliers who simply buy renewable energy certificates on the open market, Ecotricity invests heavily in generating its own power. It builds, owns, and operates its own sun and wind parks across Britain. This hands-on approach ensures a genuine and measurable contribution to the UK's renewable capacity. Their next frontier is tackling the challenge of greening the gas grid, with their innovative 'green gasmill' projects aiming to create a truly sustainable gas supply.

5. Ecotricity Customer Experience and Reviews

A company's mission is only part of the story; customer service is equally crucial. As of early 2025, Ecotricity holds a strong rating of 4.3 out of 5 on the review platform TrustPilot, based on the feedback of nearly 6,000 customers.

The positive reviews frequently highlight the quality of its UK-based customer service team and a sense of pride in supporting the company's environmental work. On the other side, some negative feedback points towards occasional technical issues with account management and, in some cases, a feeling of disconnect with the company's public political stances.

6. Additional Services and Features

Beyond standard energy supply, Ecotricity offers several other services:

• Microtricity: For households with their own solar panels or other microgeneration technology, Microtricity provides a way to sell surplus energy back to the grid. This is managed through the Smart Export Guarantee (SEG) scheme, allowing homeowners to earn money from the green energy they produce.
• Smart Meters: Ecotricity facilitates the installation of smart meters for its customers through specialised third-party partners. While there can be waiting times depending on location, the option is available for those who want to eliminate manual meter readings.
• The Ecotricity App: A dedicated mobile app allows customers to manage their account on the go. Its features include submitting meter readings, viewing statements, making payments, and accessing emergency contact information.
• Energy Efficiency: The company's focus is primarily on large-scale generation projects rather than offering domestic energy efficiency products like insulation or heat pumps. Their contribution to a greener future is at the infrastructure level.

7. How Does Ecotricity Compare to Other Suppliers?

Ecotricity's unique 'bills into mills' business model makes direct comparisons difficult. While a large supplier like EDF Energy is also a major generator of renewable energy, Ecotricity's structure as a smaller, mission-driven company provides a different proposition. Its tariff pricing is generally aligned with the broader market, with the notable exception of its price cap-exempt variable tariff.

For consumers, the choice often comes down to priorities. If the primary goal is to support a company that is demonstrably building new renewable assets in Britain, Ecotricity stands almost in a category of its own.

8. Frequently Asked Questions (FAQs)

Is Ecotricity genuinely green?
Yes. Its electricity is certified 100% green and vegan. Crucially, the company's model is built around using customer bills to fund and construct new wind and solar generation facilities in the UK, making a tangible impact on the country's renewable capacity.

Will I pay more with Ecotricity?
It depends on the tariff. Their fixed-rate tariffs are priced competitively within the market. However, their standard variable tariff is exempt from the Ofgem price cap and can be more expensive, reflecting the premium for funding new green energy projects.
