The UK government is moving ahead with a major overhaul of its electricity pricing system, aiming to break the long-standing link between gas prices and household power bills. At the centre of this push is the Department for Energy Security and Net Zero, which says the current system unfairly ties electricity costs to volatile global gas markets, even when cheaper renewable energy is widely available.Energy Secretary Ed Miliband has backed the reforms as a “once-in-a-generation opportunity” to reset how electricity is priced, arguing that the shift will help the UK deliver cleaner, more secure and ultimately cheaper energy.Under the existing model, gas-fired power often sets the price for all electricity. That means even when wind or solar generate cheaper energy, consumers still end up paying more. The government wants to change that by giving renewables a bigger role in setting prices.
Will electricity prices rise or fall?
This is the question driving debate across the UK and the answer is not straightforward.In the short term, prices could remain volatile or even rise slightly as the system transitions. Industry experts and regulators like Ofgem have warned that redesigning the market, upgrading infrastructure, and introducing new pricing models will take time and investment.But the government insists the long-term picture looks very different.Officials say that once reforms are fully in place:
- Cheaper renewable energy will directly influence bills
- Dependence on expensive gas imports will fall
- Price shocks linked to global crises could be reduced
A key proposal under discussion is “zonal pricing”, where electricity costs vary by region depending on local supply and demand. While this could lower prices in energy-rich areas (like those with strong wind generation), it has raised concerns that some regions could end up paying more.The Department for Energy Security and Net Zero maintains that consumer protections will be built in, but critics argue the system could create regional inequalities if not carefully managed.
How could the new system work?
The reforms are still under consultation, but the direction is becoming clearer. The government wants to expand long-term fixed-price contracts for renewable energy projects so developers have more certainty over returns. At the same time, it wants to reduce the role of gas in setting electricity prices, allowing cheaper wind and solar power to influence what consumers actually pay.Another idea being explored is a regional or “zonal” pricing system, where electricity costs reflect local supply and demand rather than a single national rate. Alongside this, ministers are trying to unlock more private investment into clean energy, particularly wind and solar, by creating a more stable and predictable market.Officials at the Department for Energy Security and Net Zero believe these changes could accelerate the UK’s transition to renewables. Analysts agree there is potential to attract billions in investment, but only if the final system is simple, transparent and reliable enough for long-term planning.
What are the experts warning about?
Despite the ambition behind the reforms, concerns are growing across the energy sector. Some experts warn that introducing more complex pricing systems could make bills harder for households to understand, especially if regional pricing is adopted.There are also fears within the industry that investors may hesitate if policy details remain unclear or if returns become less predictable. Large-scale infrastructure upgrades will be required to support a renewable-heavy grid, and these changes could take years before consumers see real benefits.National Grid has already pointed to the scale of transformation needed, stressing that major grid improvements will be essential to make the system work efficiently. At the same time, economists caution that if reforms are not carefully designed, they could push up costs in the short term or shift financial risks onto energy companies instead of reducing them.
