There is a lot of noise surrounding the proposed shift to Zonal Electricity Pricing in Great Britain. If you live in the South, you may have seen headlines claiming your bills are about to spike to subsidize cheaper power in the North.
However, a detailed breakdown from Octopus Energy suggests that the current “National Pricing” model is actually the reason your bills are so high today. By looking at the “whole picture” costs rather than just wholesale prices, it becomes clear that zonal pricing is a path to lower bills for everyone.
1. The Flaw in the Current System: Buying Without a Map
Currently, Great Britain operates on a National Pricing system. This means the market buys electricity based on a “graph” of price, not a “map” of location [
The system operator looks at all the available electricity generation across the country and buys the cheapest amount possible to power the whole nation. The price for every single megawatt is then set by the most expensive generator used in that half-hour window [
The problem? The system buys this energy without checking if the physical wires can actually carry it from where it’s made to where it’s needed.
2. The “Three-Payment” Trap
Because we don’t look at a map until after the energy is bought, we fall into a cycle of three expensive transactions that all end up on your energy bill:
-
Payment 1 (The Buy): We buy cheap wind power from the North [
01:41 -
Payment 2 (The Cancellation): We realize the grid can’t move that much power South without breaking. We then pay those Northern generators a “cancellation fee” to turn off. Crucially, they keep the money from the first payment too [
01:53 -
Payment 3 (The Last-Minute Fix): Because we now have a shortage of power, we have to pay a third time for local gas plants in the South to turn on at the very last minute to fill the gap. These last-minute “balancing” prices are incredibly expensive [

This “balancing market” is so broken that we are sometimes paying for enough energy to power the entire country at these emergency, last-minute prices [
3. How Zonal Pricing Changes the Game
Zonal pricing forces the market to look at a map from the very start [
-
Upfront Honesty: In a zonal market, the South might buy energy that is slightly more expensive upfront than the “paper-cheap” wind in the North. However, because this energy is local, you avoid the massive cancellation and emergency gas fees that currently inflate your bill [
02:48 -
Wasting Less: We save billions by not buying energy that we know, from the start, we will never be able to use [
03:36 -
Strategic Building: Under national pricing, companies build wind farms or batteries wherever it is cheapest for them, not where it is best for the grid [

4. The Bottom Line: Will You Pay More?
It is a common myth that zonal pricing only benefits the North. While the North may see a larger drop in costs, the UK government has committed to a framework where everyone’s bills will be lower than they are today if we adopt this reform [
The savings created by fixing the broken balancing market can be distributed in two ways:
-
Lowering everyone’s bills by the same flat amount.
-
Lowering them proportionally based on where you live [
03:11
The only people who benefit from the current “National” system are the owners of expensive, last-minute gas plants who profit from the chaos of a map-blind market [
Take Control of Your Energy Bill
Zonal pricing is used successfully in many other countries to lower costs and speed up the transition to green energy [
