Wind farms increase the average household energy bill by £70

Wind Farm Expansion and Its Impact on UK Energy Bills

As part of Ed Miliband’s initiative to transition the UK to a low-carbon energy system by 2030, new wind farms are being developed. However, a recent analysis indicates that these projects are set to increase the average household’s annual energy bill by £70 by the end of the decade.

Currently, subsidies supporting the construction of new wind farms—referred to as Contracts for Difference (CfDs)—add around £30 per year to each household’s electricity costs. This figure is projected to more than double to £70 by 2030, according to research from the think tank Onward.

Altogether, these subsidies are expected to contribute approximately £6 billion to the nation’s energy expenses. An earlier support scheme, the Renewables Obligation, which ended in 2017, will still add £8 billion to this year’s bills, with a gradual decrease to £7 billion by 2030.

The report evaluates the financial implications of the UK’s move towards a greener energy mix, a shift championed by the current Energy Secretary. Onward highlights that the multitude and complexity of renewable energy charges make it challenging for consumers to fully understand their bills.

Breakdown of Energy Bill Components

• Network maintenance costs
• Subsidies for renewable energy technologies
• Charges for smart meters
• Home efficiency improvement schemes
• Funding for major infrastructure projects, including Sizewell C and Hinkley nuclear power stations

The study notes that the increase in these levies has more than offset reductions in wholesale electricity prices, resulting in higher household bills despite falling market costs.

Onward’s analysis reveals that only 34% of the average energy bill is attributed to the electricity itself. For a typical annual bill of £963, £324 covers electricity, £200 goes to the transmission network, and an additional £300 is due to carbon taxes, VAT, and renewable levies.

There are around nine different levies included in energy bills, with CfDs among the most rapidly increasing. Government statistics indicate that the six main levies will add £14 billion to bills this year, rising to nearly £19 billion by 2030.

Currently, carbon taxes, renewable levies, and VAT account for about 30% of the average household’s energy bill—a share expected to grow as more renewable sources are integrated into the grid.

“Our findings show that the combined effect of taxes, policy charges, and renewable subsidies such as CfDs adds 30%—or £285—to the typical household energy bill,” the report states.

Concerns Over Rising Energy Costs

The report comes amid increasing anxiety about the effect of soaring energy prices on both households and businesses in the UK. The authors point out that recent price spikes, partly driven by conflict in the Gulf region, underscore the urgency of reviewing green levies.

UK Energy Prices in a Global Context

Official data shows that UK industrial and commercial electricity prices are among the highest globally, with residential prices not far behind. Since 2021, household energy debt has quadrupled to £5.5 billion.

One significant observation is that as energy prices have climbed, both consumers and businesses have reduced their electricity usage—a trend the report warns could signal economic decline.

“Britain now faces some of the highest industrial electricity costs worldwide,” the report notes.

“The UK has cut per capita energy use and overall electricity generation more than any other G20 nation. Electricity output per person is expected to drop below the global average, leaving the UK behind countries such as Iran, Libya, Bulgaria, and Belarus in per capita electricity consumption.”

Expert and Government Responses

Sir Simon Clarke, director of Onward and former Conservative MP, commented: “Our research demonstrates that British households and businesses are bearing the brunt of government policies that are outpacing practical realities. Unfortunately, Ed Miliband appears slow to acknowledge the seriousness of the situation.”

A spokesperson for the Department for Energy Security and Net Zero responded that addressing energy affordability is a top priority. The government recently shifted an average of £150 from energy bills to tax bills in the latest budget.

“We are taking steps to reduce bills both now and in the future. From April, we have removed an average of £150 from energy bills, and our commitment to clean energy by 2030 aims to protect consumers from the volatility of fossil fuel prices.”
