I'd like Green Electricity
I'm the owner of an electric car
We were the first energy supplier in the world to supply green electricity. Our electricity is 100% green,
and we have a discount for drivers of electric cars.
Our special discount for electric car owners:
With this discount you can power your home and car using 100% Green Electricity and get at least 1,000 free miles of electricity each year.To benefit from this tariff you have to drive an electric or plug-in hybrid car, and provide us with a copy of your vehicle log book (V5) or lease documents.

Assumes you use Ofgem average of 3,100 units each year for electricity on a standard meter or 4,300 units each year for electricity on an Economy 7 meter (split as 55% night and 45% day use).
We calculated the free miles your discount provides from industry data. 1kWh = 4.12 miles (source: Nissan). For a unit rate of 13.60p per kWh - £40 buys 294kW, enough for at least 1,000 miles.
If you know how much electricity you use please type in the number of units, press enter and we'll recalculate the amount for you. Prices include VAT.
Most people don't have this type of meter (if you're not sure don't tick this box).
All prices correct as of 02/03/17.
If you have gas with us, you will receive a dual fuel discount of £15 per year. This will be shown on your annual electricity summary.
You've applied for our Electric Car discount, upon successful registration you will receive a discount of £40 per year.
VAT is included. This may be different to the way such changes are displayed on a bill of statement of account. We don't lock you into a fixed term contract so your prices may go up or down in the future.
What is a kWh (kilowatt-hour)?
A unit of energy equal to the work done by a power of 1000 watts operating for one hour; or a 40-watt light bulb being left on for 25 hours.
What is the Tariff Comparison Rate (TCR)?
The TCR is a numerical value which sets out the unit price (p/kWh) for a customer with typical annual electricity consumption of 3,100 kWh/typical annual gas consumption of 12,500 kWh. It takes into account the price, tie-ins, discounts, exemptions and bundled products. The TCR is not based on your personal consumption and is not an actual price. You can ask us and any other energy supplier to send you a copy of a TCR in relation to any tariff and you can use these values to compare the various offers available in the market. Please note, however, that a TCR is a price-only index, and does not account for any other supplier attributes such as fuel mix or customer service rating. TCR does not currently apply to an E7 tariff.
I'd like Green Gas
We were the first energy company in Britain to supply green gas too - it's currently 5% green, and that percentage will grow as we build our own Green Gasmills.
We've used typical average consumption provided by Ofgem, but you can put your own figure in here and we'll automatically calculate the correct amount for you. You can find your consumption on your last bill. Prices include VAT.
All prices correct as of 02/03/17.
Call our team on 0800 999 4600 or arrange a call back and we'll call you.
Calls may be monitored for quality and training purposes.
We're open from 8:00am - 8:00pm Monday to Friday and 9:00am - 5:00pm Saturday.
