Our tariffs
We set our prices at a level that allows us to do our job of building new sources of green energy - as we seek to end the use of fossil fuels in the energy sector. We are a not-for-dividend company, the money we have (all of it) goes into our mission, to green up Britain.
(We’ll always let you know in advance if our prices are changing and tell you why that is.)
By switching to Ecotricity's green energy, you'll be helping fight climate change. We’ll use the money from your energy bills to build and maintain renewable energy sources and develop energy storage.
So switch to Ecotricity and help us end fossil fuels.
Green Variable
With no fixed contract to tie you in, you’re free to change your plan whenever you like without incurring any extra fees.
This tariff is derogated from the Ofgem price cap allowing us to build more green generation assets.

As long as you’re not tied into a fixed contract with your existing supplier, it won’t cost you anything to switch to us. Check the terms of your current contract to be sure.
Both run on a cheaper rate at night. Economy 7 usually has a cheaper rate between 12am and 7am and an EV tariff is between 12am and 5am. They could save you money if you have a night storage heater, or if you charge an electric vehicle overnight.
It stands for Pay As You Go, and it means you pay for your energy as you need it by topping up your meter with a prepayment key or card, or online or by phone if you have a smart meter. You can find out more here.
When you move into a property supplied by Ecotricity, there are several pieces of information we need to open your account:
The full address of the property you’re moving into.
The official tenancy start date or sale completion date.
Your first meter reading – this should be taken on the date that you start being responsible for the property, or within four days either side of that date. If we don’t receive a meter reading, we’ll estimate one based on the previous usage at the property. The best thing is to send us a photo of your first meter reading – make sure that you can also clearly see the meter serial number in the photo. You can send it to movinghome@ecotricity.co.uk.
The name of your landlord, letting agent or the property manager if you’re a tenant.
The full name of the account holder who’ll be responsible for paying the bills. Only one person can be named as the account holder, but we can add additional contacts if you’d like other people to be able to discuss the account.
The contact details of the account holder, including their phone number and email address. We can also add their date of birth to the account for extra security.
You can find all our domestic tariff details below.
If you have any questions about our tariffs, please get in touch.
You can find our Principal Terms and Conditions here.
We’ll write to you at least 6 weeks before the end of your tariff to let you know your options. You can choose to change your tariff at any time within 49 days of your fixed tariff coming to an end - so you can change tariff sooner than if you’d like to. You don’t have to do anything though - if you choose not to go on to another one of our tariffs, you’ll automatically move on to our Green Variable tariff - this tariff is derogated from the price cap, and is the best way to support our mission, helping us build new sources of renewable energy.
If you're on a fixed tariff and want to leave early, an exit fee will be payable. Please see the terms of your specific tariff for more details. If you move home and take us with you to your new address, no exit fee is payable.
All of our Fixed Tariffs require you to have a Smart meter installed, or agree to get one installed within 3 months of joining the tariff.
With a smart meter, you’ll;
get more accurate bills without having to submit meter readings – so you know you’ll not be paying too much or too little,
be able to see exactly how much energy you’re using in your online account,
get access to our best deals, exclusively for customers with a smart meter installed.
Better still – it helps us save the planet, as we use the information your meter provides to help balance the energy demands on the grid, meaning we, as a country, don’t produce more energy than we need. So even if you’re not on a tariff that needs a Smart meter, getting a Smart meter is a great thing to do - for your pocket, and the planet.
When the price cap was introduced, Ofgem set out rules for energy companies to apply for exemption from the cap – this is known as derogation.
Ofgem agreed that Ecotricity's Green Variable Tariff shouldn’t be restricted by the price cap, because we’re investing money from our customers’ bills into new sources of renewable energy. We call this ‘Bills into Mills’.
We set our prices at a level that enables us to do what we’re here to do - build new sources of green energy and help end the use of fossil fuels in the energy sector. As a not-for-dividend company, our money is reinvested into our mission which is helping to green up Britain.
Related FAQs - Price Change
Variable tariffs are reviewed every 3 months in line with Ofgem’s price cap updates, so the standing charge only reflects the fixed costs incurred for the relevant quarter.
Policy costs contribution to standing charges for electricity has seen a reduction from April 2026 due to the announcement in the UK Budget 2025:
Energy Company Obligation (ECO) and Great British Insulation Scheme (GBIS) Scheme will no longer be levied on energy bills.
The Renewables Obligation (RO) scheme's domestic costs is to be reduced by 75% for the customer. This will instead be met by the Exchequer. Set to be applicable from Apr 2026 - Mar 2029.
The Electricity and Gas Network costs have seen an increase due to the introduction of the RII0-3 framework, a 5 year price control for the Gas networks & Electricity Transmission networks. It has been set in place to support development of the network infrastructure, which will lower constraint costs to the grid in the long-term.
A few things determine the cost of energy – the biggest is the wholesale price of electricity and gas. Prices have been high since late summer 2021, driven by global supply chain shortages and shaped by conflicts and volatility in energy markets.
You may have seen in the news that Ofgem has announced an average increase of 13% in the energy price cap from 1 July 2026.
Ofgem says that this rise is due to higher wholesale gas prices, caused by the ongoing conflict in the Middle East.
Fluctuations in global gas prices have a disproportionate effect on our energy bills in Britain because the price of electricity is often linked to them – even when the electricity has been made by much cheaper renewables.
It’s an outdated system that’s costing us all hundreds of pounds every year, and we’ve campaigned for successive governments to ‘break the link’. Read more about our work to Break the Link.
You can find out more about how Ofgem calculates the price cap and the breakdown of changes on the Ofgem website.
10% of the energy we need to supply our customers comes from our own generation - we’ve been building more and more of it to increase this, and we'll be able to provide an updated figure very soon. We still need to buy the rest of our green energy from other sources.
Every energy company, whether deep green or fossil fuel brown, has to take part in something called the “balancing market”. Even if a company is properly hedged and produces some of its own energy, like Ecotricity, all have to go to the balancing market to match up any differences between the energy produced or bought in advance and actual demand from customers in practice. It is impossible to predict with complete accuracy exactly how much energy will be used every half hour, so there’s always a degree of a gap.
In the balancing market, each day is divided into half hour chunks, and every energy company has to balance its supply with its demand within these half hours – every half hour of every day.
On top of this, we have an outdated system for setting the price of electricity in Britain. It’s tied directly to the price of the most expensive source on the grid, which is almost always dirty fossil gas.
This means that even green electricity, which is far cheaper to make, has to be sold at the price of electricity generated by fossil gas. It also means we have no control over the price – it’s all set by international markets that fluctuate wildly in times of crisis.
That’s why it’s so important to “break the link” and why we campaign to make this a reality.
If you have a fixed Direct Debit, we review the amount you pay at least once per year. When we next come to review your payments, we’ll make any adjustments we need to in line with your latest energy use and price changes. We may also make changes outside of your regular review schedule to prevent you from paying too much or too little following a change in your prices.
No. The change in price will apply from the date in the email or letter we send you.
If you have a smart meter, we’ll get your readings automatically, unless we contact you to request one in the event they aren’t coming through correctly.
If you don’t have a smart meter, you can send us a meter reading – the easiest way to do this is via our app, through your online account, or by using our automated meter reading telephone service on 0345 555 7100 (just select option 2). Don’t worry if you don’t get around to this on the exact day of a price change. However, as long as we've received readings in the recent past, we’ll be able to estimate your usage up to the last day of the old prices.
If there has been a change to your rates, we do the sums for you, based on the usage information we hold. This is all explained in the letter or email we send you in advance of a price change. You’ll find a comparison between your current annual cost and your forecast new annual cost.
Your forecast energy usage may have changed since the last time we wrote to you, as we constantly update these projections as we receive more meter readings to better reflect your actual usage.
Firstly, make sure you’re sending us regular meter readings – the easiest way to do this is via your online account. With regular meter readings, we can be sure that we’re billing you accurately, and you’ll be able to see how much energy you’re using each month.
Or you could get a smart meter fitted. As well as saving you the hassle of submitting meter reads, smart meters help you see the energy you’re using in pounds and pence, so you can make energy saving changes to reduce the amount of energy you use every day.

At Ecotricity we’re working hard to build a greener Britain, but we appreciate that we’re not the cheapest, and we don’t want to cause you hardship. We understand if this price change means you need to switch away if you find a cheaper tariff.
If you are on one of our variable tariffs, there will be no exit fees to pay. If you switch to another supplier, you’ll keep your current rates until you leave us, as long as your new supplier tells us within 20 working days of our price change date that they’ll be taking over your supply. If you owe us any money, your switch might be held up until your account is settled. We’ll let you know if there’s a balance to pay.
If you are on one of our fixed tariffs, you may need to pay an exit fee if you leave us before your fixed tariff ends. We’ll let you know about your options for other tariffs towards the end of your fixed period.
If you’re finding it difficult to pay your energy bills, get in touch with us as early as you can on 0345 555 7100. We’ll do everything we can to make paying your bill as easy as possible for you. Visit our extra support pages for more information, or our ‘I’m Struggling to Pay’ FAQs which also gives direction on where you can get further independent advice.
The energy sector regulator Ofgem now reviews their price cap every three months.
If you are on our Pay As You Go tariffs, Void tariffs or Out of Contract rates, these follow their relevant price caps. Prices on these tariffs will change in January, April, July and October, but we’ll always let you know if your prices need to go up and give you as much notice as possible.
If you are on one of our Green tariffs, there is no fixed schedule for these as they are independent from the price cap (because they are ‘deep green’ tariffs). We review these when market circumstances mean we have to – however this does often coincide with the timing of major movements in the price cap, as we do refer to it as a benchmark.
If you are on one of our fixed tariffs, your rates never go above the rate you signed up to when you entered the fixed tariff. However, changes to some energy policy costs may mean your rates still change - this happened in April 2026, when fixed tariffs were reduced in line with government intervention to subsidise the Renewable Obligation costs, that form part of your energy costs.
Yes. If you’re a dual fuel customer (meaning you have your gas and electricity with us) and choose one of our fixed tariffs, this will apply to your electricity and gas prices. Similarly, if you choose to end your fixed tariff early, this will also apply to both fuels – exit fees may apply depending on your tariff.
Some of our tariffs have different rates depending on whether or not you pay us by Direct Debit. This is to cover the increased cost of administering manual payments. Ofgem calculates this to be about £136 per customer per year - so we reflect this in our prices. You can see all of our prices here.
Setting up a Direct Debit is easy - just go to your online account and under the "Bills & Payments", select "Direct Debit".
