What Are Green Energy Tariffs UK Households Can Trust?
Types of Green Energy Tariffs in the UK
Four main types of green tariff - each with a different level of environmental commitment.
REGO-Backed 100% Renewable Electricity
The most common. Your supplier purchases REGO certificates equal to your consumption. Available from most major UK suppliers with little or no price premium.
Direct Generator Contracts
Supplier purchases power directly from named wind farms or solar parks. Stronger environmental claim than pure REGO-backed tariffs. Offered by Good Energy and Ecotricity.
Green Gas - Biomethane
Backed by Green Gas Certificates from the Renewable Energy Assurance Limited scheme. Verified biomethane injected into the national gas grid and matched against your usage.
Time-of-Use & Smart Tariffs
Charge lower rates when the grid is predominantly renewable. Ideal for EV owners, home battery users, or households with flexible appliance schedules.

Who Benefits Most From Green Energy Tariffs?
Households on SVTs
If you haven't switched in 12+ months, you're paying the Ofgem maximum. A fixed green tariff can save £150–£400/year while reducing your carbon footprint at no extra cost.
EV Owners
Charging overnight on a green time-of-use tariff can cost as little as 7–12p/kWh instead of the standard 24.67p/kWh.
Solar Panel Owners
Combining a green import tariff with a competitive Smart Export Guarantee rate maximises your return on solar investment.
Landlords and HMO Owners
Green energy credentials are increasingly valued by tenants. Switch lets you compare green tariffs across multiple properties and simplifies the switch for rented accommodation.
Environmentally Conscious Households
For households where reducing carbon footprint is the primary motivation, Gold-accredited tariffs backed by direct PPAs offer the most traceable and genuine renewable supply.
Small Businesses
Small businesses can also compare green commercial tariffs through Switch. A renewable energy supply supports net-zero commitments and is increasingly expected by corporate customers and procurement teams.
What to Look for When Choosing a Green Energy Tariff
Price is the main factor - but check these variables too. Switch displays all of them for every result.
Unit Rate (p/kWh)
Q2 2026 cap: 24.67p/kWh. A green fixed deal with a lower unit rate saves on every kilowatt-hour.
Standing Charge (p/day)
Cap is 57.21p/day electricity + 29.09p/day gas - £314/year. Some green tariffs offer lower standing charges.
Contract & Exit Fees
Most green fixes run 12–24 months. Ofgem waives exit fees in your final 49 days. Switch displays fees clearly.
Fuel Mix & Certifications
Check for 100% renewable REGOs and Green Gas Certificates. Look for independently verified claims.
Smart Meter Compatibility
SMETS2 meters retain full smart function after switching. SMETS1 may temporarily revert - confirm before switching.
