For businesses, the decision has significant implications for future bills, investment confidence, and how energy infrastructure will evolve over the coming decade. Zonal pricing would have directly affected business electricity prices across different regions.
In this guide, we break down what zonal pricing was, why it was dropped, and what it means for UK businesses.
What Is Zonal Pricing?
Today, the UK operates with a single national wholesale price for electricity. Regardless of whether power is generated in the Scottish Highlands or consumed in central London, the wholesale price is uniform.
Under a zonal pricing model:
- The country would be split into multiple pricing regions (“zones”).
- Each region’s wholesale price would reflect local supply and demand, resulting in varying electricity rates for businesses depending on their location.
- Areas rich in renewable generation, such as parts of Scotland, would likely enjoy lower wholesale prices.
- Areas with high demand but less renewable generation, like the South East of England, would likely face higher prices.
The intention was to create a more flexible system that rewards regions with strong renewable infrastructure and encourages energy-intensive industries to locate near clean generation sources. Zonal pricing could also have led to the development of new business electricity tariffs tailored to regional conditions. As energy-intensive industries might relocate, businesses would need to monitor their electricity usage more closely to take advantage of lower regional prices.
Why Was Zonal Pricing Proposed?
Supporters argued that zonal pricing could solve several longstanding challenges in the UK energy system:
1. Reducing Wind Curtailment
On windy days, Scottish wind farms often generate more electricity than the grid can transport south. Because of limited transmission capacity, generators are sometimes paid to switch off. This “curtailment” costs the public billions of pounds per year.
2. Encouraging Investment in the Right Locations
Cheaper local electricity could attract:
- Green manufacturing sites
- Data centres
- Large industrial users
- New renewable projects
This, supporters said, could stimulate jobs in renewables-rich regions.
3. Potential Long-Term Savings
Consultants such as FTI estimated zonal pricing could save £3.7–£5 billion per year, or more than £55 billion by 2050. These savings would help businesses save money on their electricity bills over the long term.
But despite potential benefits, the proposal faced intense industry pushback.
Who Supported Zonal Pricing?
- Octopus Energy
- FTI Consulting (authors of independent analysis)
- Some academics and economists who argued it would align the UK with other OECD nations
- Stakeholders focused on reducing waste and improving renewable integration
Who Opposed It – and Why?
- SSE, Scottish Power, and RWE
- Ofgem and National Grid
- Large parts of the public (polling showed 85–90% of households in England and Wales opposed regional pricing)
Their concerns centred on unpredictable regional price differentials, which could also complicate contract terms for business energy agreements by making renewal periods, cancellation policies, and legal obligations less clear and potentially more costly.
Their concerns centred on:
1. Investor Uncertainty
Energy companies warned that unpredictable regional price differentials could make financing new wind, solar, or transmission projects riskier.
2. Potential Price Inequality
Many feared that zonal pricing would create an “energy postcode lottery,” with higher costs for businesses and consumers in the southeast and some urban regions.
3. High Transition Costs
Analysts predicted:
- A decade-long transition (likely into the 2030s)
- Up to £3 billion per year in additional system costs during implementation
4. Risk to the UK’s Decarbonisation Timeline
Opponents believed the disruption could slow the build-out of low-carbon generation, making 2035 decarbonisation targets harder to meet.
Why the Government Ultimately Dropped Zonal Pricing
On 10 July 2025, Energy Secretary Ed Miliband announced the UK would continue with a national pricing system, calling it:
“the best way to deliver an electricity system that is fairer, more affordable and more secure, at less risk to vital investment.”
Key reasons behind the decision:
- To maintain investor confidence in UK renewables
- To avoid creating regional winners and losers
- To simplify future grid planning
- To stabilise prices for homes and businesses
- To avoid delays toward the UK’s clean power goals
This announcement ended a multi-year consultation that began in 2022 and marked the conclusion of one of the most divisive debates in the energy sector in decades.
So, What is Happening Instead?
Rather than adopting zonal pricing, the government announced several reforms:
1. Strategic Grid Planning
The government will take a more proactive role in deciding:
- Where new cables and transmission lines will go
- How regions connect to new renewable projects
2. More Battery Storage
Battery infrastructure will be expanded, helping absorb surplus wind power instead of curtailing it.
3. More Efficient Network Charging
Reforms to reduce payments made to wind farms to shut down during congestion.
4. Faster Grid Connections
New policies aim to reduce multi-year wait times for businesses trying to connect to the grid.
These measures are intended to achieve some of the efficiency benefits of zonal pricing without introducing regional wholesale prices.
What Does This Mean for UK Businesses?
1. No Regional Differences in Business Electricity Prices
Businesses will continue to benefit from a simplified energy market with a single wholesale price across Great Britain.
2. Continued Investment Stability
Maintaining one national price supports investor confidence, helping keep long-term renewable electricity costs predictable.
3. Renewable Integration Will Still Improve
Although zonal pricing is gone, storage investment and improved grid planning will help reduce waste and lower system costs over time.
4. Businesses Still Need to Manage Market Volatility
A national system doesn’t protect businesses from global market fluctuations which means:
- Tariff comparison
- Contract timing
- Supplier negotiation
…remain essential.
This is exactly where Utility Bidder supports UK organisations every day.
Will Regional Price Differences Still Exist?
Although zonal wholesale pricing has been scrapped, some regional differences in business electricity costs will still remain.
This is because, even under a single national wholesale price, other parts of an energy bill vary by location, including:
- Network and distribution charges, which reflect the cost of transporting electricity and maintaining local infrastructure
- Standing charges, which can differ by region to account for local network costs
- Electricity losses, which increase the further power travels across the grid and are recovered through network charges
Crucially, these differences do not come from regional wholesale electricity prices. All businesses continue to buy power at the same national wholesale rate, avoiding the sharp regional price gaps that zonal pricing would have introduced.
Our View at Utility Bidder
As a leading UK business energy broker, Utility Bidder welcomes clarity in the UK energy market. A stable system benefits both suppliers and the businesses we support.
While zonal pricing offered some compelling efficiency arguments, the uncertainty it introduced posed significant risks for commercial customers, particularly those operating nationwide.
