Energy prices are back in the news after wholesale gas prices have risen sharply. The increase follows escalating conflict in the Middle East, including disruption to shipping routes through the Strait of Hormuz – one of the world’s most important transport routes for oil and liquefied natural gas (LNG).

Events like this can quickly ripple through global energy markets. But what does that actually mean for UK energy bills – and why do international conflicts affect what we pay here at home?

Back in March, our CEO Nigel shared an update for our customers about what was happening in the market and what it meant for them.

Why global events affect UK energy prices

The UK is one of the most gas-dependent countries in Western Europe.

Gas plays two major roles in our energy system:

  • It generates a large share of our electricity
  • It’s the main way most UK homes are heated

As Good Energy CEO Nigel Pocklington explained in a BBC Radio 5 Live interview, the UK remains heavily reliant on imported gas, producing only around 30% of the gas it uses domestically.

That means global supply disruptions – whether from geopolitical conflict, shipping disruption, or damage to energy infrastructure – can quickly affect prices.

Much of the gas Europe relies on now arrives as liquefied natural gas (LNG) from suppliers such as the United States and Qatar. If supply from these markets becomes uncertain, prices can rise rapidly as countries compete for available shipments.

Why do electricity prices rise when gas prices rise?

Even if your electricity comes from renewable sources like wind or solar, the price you pay for electricity is still influenced by gas.

That’s because electricity prices are typically set by the most expensive generator needed to meet demand at any given moment. In many cases, that generator is a gas-fired power station.

As a result, the price of gas often determines the wholesale price of electricity – regardless of whether the electricity itself was generated by wind, solar or hydro.

This is why spikes in gas prices tend to push up electricity prices too.

On a windy or sunny day, renewables can generate around half of the UK’s electricity, but the market pricing mechanism still means gas can determine the overall price.

What’s the long-term solution?

The situation highlights a longer-term challenge for the UK energy system. Domestic gas production has been declining for decades, and even if new reserves were developed, they would only add a small amount to overall supply.

That means the UK would continue to rely on international markets for a large share of its energy, and remain exposed to price volatility as a result.

Expanding homegrown renewable energy offers a different path. Wind and solar don’t rely on imported fuel, and once built their costs are largely stable. Increasing domestic renewable generation – alongside storage, smarter grids and electrification – is widely seen as one of the most effective ways to reduce long-term energy price volatility while strengthening the UK’s energy security.
