Ecotricity stands out as Britain’s pioneering green energy company. They combine renewable energy supply with environmental activism.

The supplier operates 24 wind farms across the UK. They invest customer payments into new renewable projects.

Company Origins and Mission

Ecotricity started in 1995 as the world’s first green energy company. Dale Vince founded it with a mission to change how Britain makes and uses energy.

They’re more than just an energy supplier. Their approach is “energy with a conscience,” focusing on building new renewable sources instead of just trading existing power.

They operate from Stroud in Gloucestershire. Their headquarters runs entirely on renewable energy from their own wind turbines.

Business Energy Tariffs and Pricing

Ecotricity keeps its business energy tariffs straightforward, focusing on 100% green electricity and carbon-neutral gas.

Ecotricity keeps its business energy tariffs straightforward, focusing on 100% green electricity and carbon-neutral gas. Their pricing is transparent, but costs are usually higher than market rates because they invest in renewables.

Types of Business Tariffs

Ecotricity’s variable tariffs are their standard business offering. These supply 100% green electricity from their own generation assets.

They also offer green gas. Since making green gas is tough, they provide carbon-neutral gas by investing in carbon reduction programmes.

Made-to-measure tariffs are available for larger businesses. These bespoke deals suit multi-site operations and those with higher energy needs.

Business customers get help from dedicated account managers. This support makes it easier to choose the right tariff.

Ecotricity serves SMEs, large enterprises, and multi-site users. Their tariffs fit different usage patterns and business sizes.

Price Structure and Transparency

Business electricity rates include unit rates (price per kWh) and daily standing charges. Usually, the unit rate affects your total costs most.

Ecotricity keeps tariffs fair and simple, with no hidden fees or confusing discounts. They don’t bother with the complicated pricing you see elsewhere.

Their “bills into mills” philosophy means customer payments go straight into new UK renewable projects, not just buying energy certificates.

Business energy costs with Ecotricity are generally higher than cheaper alternatives. That premium funds renewable infrastructure and their ethical business model.

Companies can request quotes based on their energy use. Pricing depends on location, usage, and contract needs.

Exit Fees and Contract Terms

Contract terms depend on the tariff. Variable tariffs usually offer flexibility and don’t lock you in for ages.

Exit fees might apply to some business contracts, especially fixed-term ones. Always check the terms before signing.

Bigger businesses with bespoke tariffs might get different contract structures, often tailored to their needs.

Ecotricity tries to keep things fair rather than tying you down with harsh contracts. This approach extends to their cancellation policies too.

It’s smart for businesses to compare contract terms as well as prices. Knowing the exit details helps you make the right choice.

Renewable Solutions for Businesses

Ecotricity helps businesses install their own renewable energy through wind turbine projects and solar panel systems.

Business Wind Energy Benefits:

  • Fixed-rate contracts shield you from price swings
  • Lower carbon footprint with 100% renewable generation
  • Long-term savings versus traditional energy

Their wind turbines generate clean electricity with no carbon emissions during use. The UK’s windy climate means the turbines work well all year.

Businesses can get wind-generated electricity through Ecotricity’s supply deals. These guarantee the energy comes from wind, not fossil fuels.

Solar Panel Options

Ecotricity invests in solar projects so businesses can get clean electricity from solar panels. They develop installations that turn sunlight into renewable power for commercial customers.

Solar Energy Features:

  • Generates electricity during daylight, cutting peak-time costs
  • Solar panels need little upkeep once installed
  • Clean energy with zero operational emissions

Solar panels use photovoltaic tech to turn sunlight into electricity. Ecotricity’s projects let businesses tap into solar without putting panels on their own buildings.

Solar electricity mixes with Ecotricity’s green supply for 100% renewable power. Solar and wind together create a diverse energy portfolio.

Ecotricity’s Green Initiatives and Impact

Ecotricity runs programmes to cut emissions and push renewable energy development across Britain.

Carbon Footprint Reduction

Ecotricity aims to cut operational carbon emissions by 90% by 2030 as part of the Green Britain Group’s net zero goal. That’s much faster than the usual 2050 target.

Business travel and building heating make up nearly 90% of their carbon footprint. They already report zero carbon footprint for electricity use, since it’s all renewable.

Key strategies:

  • More public transport for business travel
  • Car sharing for meetings and events
  • Using electric vehicles when possible
  • Switching from gas to electric heating
  • Boosting energy efficiency in offices

They hold electronic meetings but still keep some face-to-face time. They’ve approved investment for heating upgrades and building improvements.

Green Gas Mills

Ecotricity came up with “green gas mills” to create renewable alternatives to fossil gas. These use anaerobic digestion tech to turn organic waste into biomethane.

They run several green gas mills in Britain, processing farm waste, food waste, and energy crops. This biomethane goes into the national gas grid as a carbon-neutral option.

Green gas production helps farmers earn more and cuts methane from waste. The process also creates digestate, a handy organic fertiliser for farms.

Sustainable Investment Approach

Ecotricity uses customer bill payments to fund new renewable projects, not just for shareholder profit. This has helped them build 74 windmills and 3 sun parks across Britain.

They reinvest revenue into expanding Britain’s renewable capacity through wind and solar. Every customer directly helps reduce fossil fuel use.

Ecotricity also supports international carbon reduction projects. They hold ethical accreditation for sustainable business and environmental responsibility.

Switching to Ecotricity means meeting certain business criteria and following their switching process. They support you through the transition and give clear guidance for different business types.

Eligibility and Onboarding Process

Ecotricity accepts a range of business types, including SMEs, large enterprises, multi-site operations, and businesses with half-hourly metering. They cater to sectors from manufacturing to independent shops and venues.

Eligible Business Types:

  • Small and medium enterprises (SMEs)
  • Large commercial operations
  • Multi-site businesses
  • Half-hourly metered customers

The onboarding starts with a review of your energy profile and needs. Ecotricity reps work with you to understand your tariff options and explain available rates.

During the first consultation, they’ll look at your current usage, contract terms, and sustainability goals. They then offer recommendations based on your operations and green objectives.

You’ll usually need to provide recent energy bills, site details, and meter info. For multi-site businesses, you might need to share extra location data for accurate pricing and service.

Switching Guidance and Considerations

Switching business energy suppliers is definitely more involved than changing domestic providers. Tariffs are bespoke, contracts run for all sorts of lengths, and billing can get a bit complicated.

It’s important to check when your current contract ends. If you switch to Ecotricity too early, you might get hit with termination fees.

Key Switching Considerations:

  • Contract notice periods
  • Exit fees and penalties
  • Meter reading requirements
  • Service continuity during transfer

Ecotricity suggests comparing their green tariffs with your current supplier’s rates. Their Bills to Mills programme uses extra profits to fund new renewable energy projects, so your business actually helps grow the UK’s green energy capacity.

Switching usually takes about two to three weeks for most businesses. If your site uses half-hourly metering, expect a bit more time for data checks and the transfer.

Gather your recent bills, jot down meter readings, and decide who’s going to handle your account. Ecotricity’s business support team is on hand to help during the switch.
