The fourteen Agile regions: why prices differ across Great Britain
Last updated: 10 August 2026
Look up today's Agile prices in London and in North Scotland and you'll get two different sets of numbers — same tariff, same half hours, different pence. Every Agile price is really fourteen prices, one per Great Britain electricity region, and knowing your region letter is step one of getting any of the numbers right.
Where the regions come from
The fourteen regions predate Octopus by decades: they're the areas of the old regional electricity boards, which live on as the distribution networks that carry power the last miles to your house. Each region is its own "grid supply point group" with its own letter — A to P, skipping I and O because on a meter document they'd read as 1 and 0.
Prices differ between regions because the costs layered on top of the wholesale price differ: each distribution network sets its own charges, and how much electricity is lost in transit varies with the geography of the network. The shape of the day — cheap overnight, a spike around 4–7pm — is broadly shared nationwide because the wholesale market underneath is shared; it's the exact pence that shift by region. The practical consequence: any tool or spreadsheet scoring Agile prices has to score your region's rates, or its recommendations are subtly wrong.
The fourteen regions
| Letter | Region |
|---|---|
| A | Eastern England |
| B | East Midlands |
| C | London |
| D | Merseyside & North Wales |
| E | West Midlands |
| F | North East England |
| G | North West England |
| H | Southern England |
| J | South East England |
| K | South Wales |
| L | South West England |
| M | Yorkshire |
| N | South & Central Scotland |
| P | North Scotland |
Northern Ireland has a separate electricity market and isn't covered by Agile, which is why the map stops at Great Britain.
How to find your region
-
From your postcode. The first half of a postcode — the outward code,
the
SW1AofSW1A 1AA— is enough to place you in a region. This is how Cheap Hours does it: your browser trims the postcode to the outward code on your own device, and only that part is used for the lookup, so your full postcode never leaves your machine. -
From your Octopus tariff code. If you're already on Agile, your
account shows a tariff code like
E-1R-AGILE-24-10-01-C. The letter at the very end is your region. - From the list. If you'd rather type nothing at all, just pick your area from the table above — Cheap Hours offers the same list.
Does the region change the advice?
Mostly no — and that's worth saying plainly. Whichever region you're in, the playbook is the same: avoid the evening peak, aim delay timers at the overnight trough, watch for plunge days. What changes is the arithmetic — exactly which half hour is cheapest tonight, and by how much — and that's the part worth automating. Cheap Hours keeps your region letter on your device and scores every recommendation against your local rates.
Type the first half of your postcode — or pick from the list — and every recommendation is scored against your region's actual prices.
