Green Energy Is Often the Same Price or Cheaper

The idea that green energy costs more is one of the most persistent myths in the UK energy market. In 2026, many renewable energy tariffs are priced the same as — or cheaper than — standard energy deals.

Why Green Energy Used to Cost More

Historically, green tariffs were more expensive due to several market factors that no longer apply today.

Limited Renewable Generation

In the past, renewable energy sources were less developed and couldn't meet large-scale demand, driving up costs.

Higher Production Costs

Early renewable technology was expensive to manufacture and install, with costs passed to consumers.

Fewer Competitors

Limited suppliers offered green options, reducing market competition and keeping prices high.

Important Update for 2026

Those conditions no longer apply in today's energy market.

What Changed in the UK Energy Market?

By 2026, the renewable energy landscape has transformed dramatically, making green energy more accessible and affordable than ever before.

50%+ Renewable Power

Renewable electricity now supplies over half of UK power generation, increasing availability.

Cheapest Generation

Wind and solar are among the cheapest sources of electricity generation today.

Widespread Availability

Most major suppliers now offer green tariffs, increasing market competition.

Green Energy vs Standard Energy: Price Comparison

Energy Type Typical Cost in 2026 Key Features Savings Potential
Green Electricity Same Price 100% renewable, same unit rates & standing charges No extra cost for renewable
Standard Electricity Standard Price Mixed generation sources No price advantage
Green Gas Slight Premium Carbon offset or biomethane blends Often offset by electricity savings
Standard Gas Standard Price Traditional natural gas supply Base pricing

Key Finding for 2026

In many postcodes, green electricity costs no more than non-green electricity. The small premium for green gas is often offset by electricity savings when choosing comprehensive green tariffs.

Fixed vs Variable Green Tariffs: Which Saves More?

Fixed Green Tariffs

Often the cheapest option - lock in renewable electricity prices at competitive rates

✅ Frequently priced below the Ofgem price cap

✅ Protection against future price rises

✅ Best for budget planning and long-term savings

Variable Green Tariffs

Typically more expensive - track the energy price cap without price certainty

⚠️ No exit fees but less predictable

⚠️ Usually more expensive long-term

⚠️ Not ideal for maximizing savings

Potential Annual Savings

£0 - £300+

Many households switching to fixed green tariffs save money compared to standard variable tariffs, particularly when moving from price-capped options to competitively priced green deals.
