Why choose a green energy tariff?
Green energy tariffs match your usage with electricity generated from renewable sources such as wind, solar, and hydro. Many plans also include green or carbon-offset gas, helping you reduce your footprint without changing how you use energy.
- Lower your carbon footprint with 100% renewable electricity matching
- Support UK renewable generation via REGOs (Renewable Energy Guarantees of Origin)
- Access modern features: time-of-use pricing, EV off-peak rates, and smart integrations
- Competitive pricing that can align with the Ofgem price cap for standard variable tariffs
How green tariffs work in the UK
When you choose a green tariff, the electricity you use is matched with renewable generation that’s verified by REGOs. Your supplier purchases REGOs to prove an equivalent amount of renewable electricity has been added to the grid.
Gas can be supplied as green in two main ways:
- Biomethane (green gas) injected into the grid and matched to your usage
- Carbon-offset gas where emissions are balanced with certified offset projects
Note: Energy always flows from the grid mix to your home or business. The green benefit comes from your supplier’s sourcing and certification.
Latest green tariff types in 2025
Standard Variable (Green)
Flexible, usually price-cap aligned. Rates can move up or down with the market, and there’s often no exit fee.
EV & Time-of-Use Tariffs
Cheaper off-peak rates for overnight EV charging or smart appliances. Requires a smart meter; ideal for EV owners and flexible usage.
Solar + Battery Friendly
Pair your green import tariff with the Smart Export Guarantee (SEG) to earn for exported solar. Some suppliers offer enhanced export rates.
Green Dual Fuel
Bundle renewable electricity with green or carbon-offset gas. Useful for simplicity and single billing.
What to look for when comparing the latest green tariffs
| Feature | Why it matters | What good looks like |
|---|---|---|
| Renewable % & REGO transparency | Confirms the tariff’s green credentials | 100% renewable electricity with clear REGO sourcing |
| Unit rate & standing charge | Core cost factors; vary by region and meter type | Competitive rates; fair standing charge |
| Exit fees | Affects flexibility if prices fall or your needs change | Low or no exit fees |
| Smart meter compatibility | Needed for time-of-use and EV rates | SMETS2 smart meter with half-hourly data option |
| Green gas vs offset gas | Determines real-world emissions impact | Biomethane where possible; credible offsets if used |
| Export options (SEG) | Earn for exporting solar/battery energy | Simple sign-up; competitive export rate |
Tip: If you have an EV or can shift usage to off-peak hours, a time-of-use green tariff can significantly reduce bills while increasing renewable consumption when the grid is cleaner.

Green energy FAQs
Are green tariffs more expensive?
Not necessarily. Many green tariffs are competitively priced and some standard variable green plans align with the Ofgem price cap. The best value depends on your region, usage, and meter type.
What’s the difference between green, renewable, and eco tariffs?
In general, “green” and “renewable” refer to electricity matched with sources like wind, solar, or hydro via REGOs. “Eco” is a broader marketing term that may also include carbon-offsetting. Always check the supplier’s fuel mix and certification.
Do I need a smart meter?
You can get a green tariff without one, but smart meters are required for time-of-use and most EV tariffs. They also provide more accurate bills and can help track usage.
Can renters switch to a green tariff?
If you’re the bill payer, you usually can. Check your tenancy agreement for any clauses and inform your landlord. The switch does not require property changes.
What is the Smart Export Guarantee (SEG)?
SEG pays you for exporting surplus electricity to the grid from solar PV, wind, or other eligible microgeneration. You can have a green import tariff and a separate SEG export agreement.
Is green gas the same as carbon-neutral gas?
No. Green gas typically refers to biomethane matched to your usage. Carbon-neutral gas often relies on verified offsets to balance emissions. Both reduce impact, but they’re different mechanisms.
How fast can I switch?
Online applications take minutes. The full supplier handover usually completes within days, and you won’t lose supply during the switch.
