Why Compare Renewable Energy Suppliers in the UK?
Renewable energy is now mainstream in the UK. More than half of UK electricity generation comes from renewable sources, and most major suppliers offer green tariffs. However, not all renewable energy suppliers are equal — either in price, transparency, or environmental impact.

Key Insight for 2026
Many households switching to renewable energy pay the same or less than standard tariffs — but only if they compare properly. Without comparison, you could miss out on significant savings or choose a supplier that doesn't match your environmental values.
What Counts as a Renewable Energy Supplier?
In the UK, a renewable energy supplier typically offers sustainable energy solutions:
Renewable Electricity
100% renewable electricity backed by REGOs, generated from wind, solar, hydro, or biomass sources with full transparency
Low-Carbon Gas Options
Standard gas supply with carbon offsetting, or partial biomethane blends for reduced environmental impact
Are All "Green" Energy Suppliers the Same?
NO. Suppliers vary significantly in their approach to renewable energy and sustainability.
| Aspect | Basic Green Suppliers | Advanced Renewable Suppliers |
|---|---|---|
| REGO Sourcing | Buy cheap certificates only | Invest directly in UK renewables |
| Price Competitiveness | Premium pricing for green energy | Match or beat standard tariff prices |
| Renewable Investment | Minimal new investment | Fund new renewable projects |
| Supply Transparency | Vague about energy sources | Full supply chain disclosure |
| Customer Support | Standard support channels | Dedicated green energy advisors |
