Among the many developments of 2025, few carried longer-term significance than the government's decision on the future shape of electricity pricing. After years of consultation under the Review of Electricity Market Arrangements (REMA), ministers confirmed in July that they would not introduce zonal pricing, choosing instead to reform the existing national system. It was a landmark moment — and one that settled a debate which had divided the industry.
What Was at Stake
Zonal pricing would have divided Great Britain into regional pricing areas, so that the cost of electricity reflected local conditions of supply and demand. Proponents argued it would use the grid more efficiently and send better signals about where to build generation and demand. Opponents warned it would create regional winners and losers, complicate contracts and deter investment by adding uncertainty. The stakes, for a market mid-way through a vast transformation, were considerable.
Zonal versus national, in brief
Under national pricing, the wholesale price is the same across the country. Under zonal pricing, it would vary by region. The government's decision preserves a single national price while pursuing other reforms to improve how the system uses the grid.
Why the Decision Mattered to Advisors
For brokers and consultants, the choice to retain national pricing removed a significant source of potential complexity. Zonal pricing would have introduced regional variation into every commercial conversation, requiring advisors to factor a customer's location into pricing in ways that did not previously apply. The decision to reform the national system instead preserved a more familiar landscape — albeit one still subject to ongoing change.
Reform Continues by Other Means
Rejecting zonal pricing did not mean rejecting reform. The government committed to improving the national system through other measures — strengthening locational signals for investment, reforming grid connections and supporting flexibility. For advisors, the lesson was that the market's plumbing continues to evolve even when the headline structure stays the same, and that staying informed remains part of the job.
“The zonal pricing decision settled one of the biggest open questions in the market. But reform did not stop — it simply took a different road.”
