Find renewable electricity and greener gas tariffs for your home in England, Scotland and Wales. Compare transparent prices, understand what’s really green, and switch online in minutes with zero disruption to your supply.
Answer a few quick questions to see available green tariffs tailored to your home, meter type and usage. We’ll show estimated monthly costs, unit rates, standing charges, contract length, and how green each tariff really is.
What is a green energy tariff?
In the UK, a green energy tariff typically means your supplier matches your electricity use with power generated from renewable sources (such as wind, solar and hydro) by buying Renewable Energy Guarantee of Origin (REGO) certificates. This doesn’t send renewable electrons directly to your home, but it ensures an equivalent amount of renewable electricity is added to the grid.
Green electricity: Often marketed as 100% renewable when backed by REGOs. Some suppliers also own or directly contract with renewable generators.
Greener gas: Full 100% renewable gas for homes is rare. Most green gas tariffs blend a small percentage of biomethane with fossil gas and/or offset the remaining emissions via carbon projects.
Additionality: Some tariffs fund new renewables or community projects. If this matters to you, look for clear evidence of direct investment or power purchase agreements (PPAs).
Note: Energy markets in Great Britain are regulated by Ofgem. Suppliers must accurately describe their fuel mix and any environmental claims.
Prices and availability differ by region in Great Britain due to network costs. Northern Ireland has a separate market and is not included.
How switching to a green tariff works
Enter your details: Provide postcode, meter type and usage (or choose a typical usage profile).
Compare your options: We show live tariff information, including unit rates, standing charges, contract length, any export rates, and the supplier’s green credentials.
Apply online: Confirm your switch. Your new supplier manages the process, including closing your old account. You’ll send opening meter readings if required.
No interruption to your gas or electricity supply.
Warm Home Discount and Priority Services Register status can be moved to your new supplier (check eligibility and timelines).
Find the right green tariff for your home
Renters and movers
Look for no-exit-fee variable tariffs or shorter fixed terms for flexibility. Keep a photo of your meter and update readings during check-in/out.
Electric vehicle owners
Consider time-of-use or EV-specific tariffs with cheap overnight rates. Schedule charging to off-peak windows to cut costs and emissions.
Heat pump households
Smart time-of-use tariffs can reward load shifting (pre-heating or thermal storage) while keeping your electricity 100% renewable.
Solar PV homes
Pair a green import tariff with a competitive Smart Export Guarantee (SEG) rate to get paid for what you export.
Low-usage households
Focus on standing charge levels. A lower daily charge could beat a slightly cheaper unit rate.
Practical tips for a cleaner, cheaper bill
Have your MPAN (electricity) and MPRN (gas) to hand for a smoother application (you can usually find them on a bill).
Provide accurate annual kWh usage for the most reliable comparison (check your last 12 months of bills or smart meter data).
Consider a smart meter to unlock more green/time-of-use options and accurate billing.
Check whether a tariff supports additionality if you want your choice to help fund new renewable generation.
Green energy tariff FAQs
Is green energy more expensive?
Not necessarily. Prices vary by market conditions, region and tariff type. Fixed green deals can be competitive with conventional tariffs, and variable tariffs may be governed by the price cap. Compare options to find the best fit for your usage.
What are REGOs?
Renewable Energy Guarantees of Origin (REGOs) certify that a supplier has matched your electricity with generation from renewable sources over a year. They do not guarantee your home receives renewable electrons, but they support renewable output on the grid.
Can I get 100% renewable gas?
Pure 100% biomethane for domestic customers is uncommon. Most green gas tariffs include a smaller biomethane share and/or carbon offsetting. Check the percentage and methodology in the tariff details.
Will my supply be interrupted when I switch?
No. Your gas and electricity stay on. The switch is handled between suppliers using industry processes. You may be asked for meter readings to finalise your old account.
The cap limits the unit rates and standing charges for standard variable tariffs in Great Britain, including green SVTs. It does not apply to fixed tariffs you choose to sign up to. We reflect current cap impacts in your comparison where relevant.
SEG pays you for excess electricity exported to the grid from solar PV, batteries or other microgeneration. You can choose a green import tariff and a separate SEG export tariff, possibly from different suppliers.
