What is green energy?

How do renewable energy tariffs work?

Renewable energy tariffs are great for those who want to do their bit for the environment, but don’t want to invest in costly solar panels or installing wind turbines.

Renewable energy tariffs work just like any other, but with an emphasis on providing environmentally friendly gas and electricity. Your supplier might pledge to generate a certain proportion of your energy from renewables, or they might promise to match however much energy you use with energy generated sustainably. Similarly, if you choose them they might offer to invest in renewable development programmes in return for becoming a customer.

How is renewable energy generated?

In the UK, the highest percentage of renewable energy is generated by wind farms. A lot of renewable energy is also generated from biomass fuel and solar panels.

What’s the difference between a renewable energy tariff and a ‘feed-in-tariff’ (FIT)?

If you’re interested in an environmentally friendly energy solution, you might have come across the phrase ‘feed-in-tariff’ (FIT).

Whereas renewable energy tariffs see suppliers offering to source energy responsibly or invest in renewables, a FIT is a government scheme that gives money back to households that generate their own electricity.

Solar panels, wind turbines, and hydroelectricity are all ways that households can generate their own power. Any excess energy created is sold back to the National Grid. The amount of money you could receive depends on how much is generated.

If this sounds up your street, make sure you use a qualified FIT installer, and that whatever technology you have installed is certified under the Microgeneration Certification Scheme (MCS).

Which companies offer renewable energy tariffs?

Here are just a few companies that source their energy from 100% renewable sources.

  • Bulb;
  • Ecotricity;
  • Engie;
  • Eon;
  • Octopus Energy;
  • Ovo.

Other suppliers, while not completely renewable, may offer a green tariff powered by environmentally friendly sources.

Are renewable energy tariffs cheap?

Green energy tariffs might not be the absolute cheapest on the market, but they often rival regular plans in price. Especially as more and more suppliers offer green energy plans, prices are steadily decreasing.

Remember, though, there’s no single cheapest energy tariff – just the most affordable for your location and needs. Enter your postcode below to find and compare tariffs in your area.

    • Tariffs

      Tariffs can be pretty confusing, so we’ve explained the most common ones below.

      Standard tariffs

      This is the name given to your supplier’s ‘default’ tariff. The prices of standard tariffs go up and down with the energy market. Some supplier’s refer to this as an ‘evergreen’ tariff.

      Fixed energy tariffs

      These tariffs offer guaranteed charges and rates. A fixed energy tariff normally lasts until a defined date set by the supplier.

      Dual fuel tariffs

      A dual fuel tariff is a tariff which provides electricity and gas from the same supplier. Sometimes referred to as ‘bundling’, dual fuel energy tariffs are often easier to manage for customers. Similarly, dual fuel tariffs are often cheaper for customers, as suppliers offer deals to try and stop you switching to competitors.

      Pre-Payment tariffs

      These tariffs are for people with prepayment meters and enable customers to pay in advance for gas and electricity by ‘topping-up’ their meter using prepay tokens, cards or a key.

      ‘Green’ energy tariffs

      A ‘green’ tariff can be one of two things. Either the supplier will promise to match your usage with generation from renewable sources of energy, or it will contribute towards environmental schemes on your behalf.

      Feed in tariffs

      This is where you’ve installed solar panels or wind turbines at your property, and the energy suppliers pay you for the energy produce.

    • How to switch

      Switching tariff is a great way to make big savings. Energy try to keep long term customers who never gets round to switching. UK customers overpay £1.7billion a year on energy bills because they can’t be bothered to switch!

    • FAQs

      We’ve put together a list of the most asked energy questions by our users.

      Do I have to contact my current supplier if I switch?

      Nope. New suppliers take care of everything, and this includes cancellation of your old tariff. Similarly, new suppliers will organise the switch date. This means you won’t be charged twice for the service. Make sure you cancel your Direct Debit after your final payment to your old supplier, just to be on the safe side.

      How long does switching take?

      Most switches are done within 17 days, but it can take up to 3 weeks. Your new supplier will let you know your exact switch date.

      Also check if the supplier you want to switch to is signed up to the Energy Switch Guarantee. The Guarantee means suppliers have to stick to certain rules such as allowing a 14 day cooling off period if you change your mind or aren’t happy with your service.

      Will I be billed twice?

      New suppliers will only start charging from your switch date. So no, you shouldn’t be charged twice. Do cancel your Direct Debit though, just to make sure!

      When do I begin paying my new supplier?

      The old supplier will send you a final bill for the period up to the switch date. On that date, the new supplier takes over.

      Will I be charged an exit fee for leaving my current supplier?

      If you switch within the 6 to 7 weeks before the end of your current plan, the exit fee will be waived.

      This is a rule put in place by Ofgem, and all suppliers have to follow it.

      Should I cancel Direct Debits?

      After the final payment, cancel your direct debit just to be on the safe side.
