There has been a renewed focus on whether gas and electricity prices should be decoupled in the UK energy market. Recent developments suggest that this is no longer just a theoretical discussion, but a genuine policy direction being explored.
Government ministers, particularly Rachel Reeves and Ed Miliband, are fronting the discussions, both saying they are “working to come up with a practical way” to break the link. However, while the intent is clear, the path forward is far from straightforward.
Why Gas Still Sets Electricity Prices
At present, the UK operates under a marginal pricing system. In simple terms, the most expensive form of generation needed to meet demand, which is often gas, sets the price for all electricity.
This means that even when a large proportion of electricity is generated from cheaper renewable sources such as wind and solar, prices can still rise in line with gas costs. As a result, organisations remain exposed to global gas market volatility, even as the energy mix becomes greener.
Recent geopolitical tensions particularly in the Strait of Hormuz have reinforced this issue, as fluctuations in gas markets continue to feed directly into electricity pricing across both the UK and Europe.
Government Plans to Break the Link
The current government has made it clear that reducing the influence of gas on electricity prices is a priority. This sits alongside wider ambitions to accelerate net zero and improve energy security.
Several approaches are being considered. One key option is expanding the use of fixed-price contracts for renewable generators, ensuring that cheaper electricity is not priced at the same level as gas. There is also ongoing discussion around reforming the marginal pricing system itself, although this would represent a significant structural change.
The overall aim is not simply to lower costs in the short term, but to create a more stable and predictable pricing system that reflects the growing role of renewable energy.
Why Fully Decoupling is Difficult
Despite the ambition, fully separating gas and electricity prices is complex. Gas remains an essential part of the energy system, particularly as a backup when renewable generation is low. As long as this remains the case, gas will continue to influence electricity prices to some degree.
There is also the wider European context to consider. Electricity markets across Europe are still closely linked to gas, and the UK cannot operate entirely in isolation. Any major reform must take account of cross-border trading and market alignment.
In addition, changing the pricing system involves regulatory reform, infrastructure investment, and long-term contractual arrangements. These are not changes that can be implemented quickly.
A Gradual Shift Rather Than a Sudden Change
Given these challenges, it’s unlikely that there will be a single moment where gas and electricity prices are fully separated. Instead, the more realistic outcome is a gradual shift. Over time, the influence of gas is expected to reduce as more renewable energy is brought onto fixed pricing mechanisms and the market structure evolves.
This means organisations are more likely to see incremental changes rather than an immediate transformation in how electricity is priced.
The Role of Political Uncertainty
One of the biggest questions surrounding these plans is whether they will be carried through to completion. Energy market reform of this scale typically takes years. This creates a clear risk that future governments could change direction, delay progress, or adjust the scope of the reforms.
However, once structural changes begin to take shape, such as new contracts, regulatory frameworks, and investment commitments, they become increasingly difficult to reverse. Altering course at that stage would carry financial, legal, and investor confidence implications.
For this reason, a complete reversal is unlikely. A more probable scenario is that future governments refine or slow the pace of change rather than abandoning it entirely.
The push to separate gas and electricity prices reflects a broader shift in how the energy system is evolving. There is clear momentum behind reducing the impact of gas, but the process will be gradual and subject to change.
In practice, this means organisations should prepare for a market that is moving in a new direction, but not yet settled. Clarity will improve over time, but in the short term, navigating uncertainty will remain essential.
