Picture two cafés. Each uses 10,000 kWh of electricity a year, and each has the same supplier on the same contract length. One is in Nottingham, the other in Wrexham. On Ofgem's regional data, the Wrexham café ends the year roughly £300 worse off. Nothing about the coffee explains it. The postcode does.
So yes, small business electricity prices do change with your postcode. But by how much, and compared with what else, is more interesting than the league tables you may have seen. This guide uses official regional data to show what your area does to your bill, explains what matters more, and shows how to get a business electricity quote that reflects your actual location.
Quick answer: Yes. On Ofgem's regional data, the gap between the cheapest and dearest region is about £310 a year at 10,000 kWh, roughly 11%. Thirteen of the 14 regions sit within about £155 of each other. Your contract matters far more: a lapsed fixed deal can add around £1,950 at the same usage.
Why does your postcode change small business electricity prices?
Electricity is traded nationally, so the energy itself costs broadly the same in Cornwall as in Carlisle. The difference comes from moving it to your meter. Two sets of network charges vary by location, and your supplier blends both into your rates.
Distribution charges (DUoS)
Your Distribution Network Operator (DNO) charges business electricity suppliers for carrying power across local cables and substations. Great Britain has 14 DNO areas run by six companies, and sparse, rural networks cost more per customer to maintain. Our guide to business electricity rates by region covers DUoS in more depth.
Transmission charges (TNUoS)
These fund the high-voltage grid and vary by zone. They rose from about £16 to £31 per MWh from April 2026 (MoneySuperMarket), and they lean the opposite way to distribution costs. For standard meters, NESO's 2026/27 per-unit tariffs are nil in seven zones running from Northern Scotland down to the East Midlands, then rise to 0.70p/kWh in London, 1.01p/kWh in the Southern zone and 2.07p/kWh in the South West (Business Energy Deals). Those charges apply to weekday early-evening use (Drax).
Because business electricity suppliers fold both into one unit rate and one standing charge, you never see them itemised. That is why a single "cheapest region" ranking is so often unreliable. For the wider picture, see how your business electricity rates are calculated.
Bill component | Same everywhere? | Who sets it |
Wholesale energy | Broadly yes | The market |
Levies and policy costs | Mostly | Government and Ofgem |
Transmission (TNUoS) | No, varies by zone | NESO and Ofgem |
Distribution (DUoS) | No, varies by DNO area | Your DNO, regulated by Ofgem |
Supplier margin and broker commission | No, varies by supplier | Supplier and broker |
Your postcode decides your DNO area and transmission zone. Those set the network charges built into every quote.
Small business electricity prices by region: what the data shows
Business electricity suppliers do not publish business tariffs region by region, and business rates change daily. The one place all 14 regions appear in a single official table is Ofgem's household price cap, which reflects the same regional network costs. It is not a business tariff, so read it as a map of the pattern, not a quote. We used the October to December 2026 rates to work out annual electricity costs at 10,000 kWh, typical of a small shop, salon or café.
MPAN code | Region | DNO operator | Unit rate (p/kWh) | Standing charge (p/day) |
10 | Eastern England | UK Power Networks | 26.61 | 51.84 |
11 | East Midlands | NGED | 25.36 | 51.45 |
12 | London | UK Power Networks | 26.60 | 42.92 |
13 | Merseyside and North Wales | SP Energy Networks | 27.86 | 67.66 |
14 | West Midlands | NGED | 25.60 | 57.23 |
15 | North East England | Northern Powergrid | 25.46 | 61.58 |
16 | North West England | Electricity North West | 26.49 | 45.68 |
17 | North Scotland | SSEN | 26.35 | 55.14 |
18 | South and Central Scotland | SP Energy Networks | 26.11 | 61.41 |
19 | South East England | UK Power Networks | 26.88 | 52.32 |

The cheaper end
East Midlands comes out cheapest at £2,724 a year, followed by the West Midlands, North East and Yorkshire, all under £2,790. East Midlands and Yorkshire also appear among the lower-cost networks in business energy commentary from MoneySuperMarket.
The dearer end
Merseyside and North Wales is the outlier at £3,033, about £309 (11%) above East Midlands. It has the highest unit rate and the highest standing charge in Great Britain. Business commentary also flags North Scotland and the South West as pricier areas, yet on household data North Scotland sits mid-table and the South West only a little higher. The picture shifts with the type of customer, which is why a quote should reflect your own meter and postcode.
Why "cheapest region" depends on how much you use
Regions trade unit rate against standing charge. London has the lowest standing charge in Great Britain but a mid-table unit rate. East Midlands has the lowest unit rate but pays more in standing charge than London. So rankings flip with usage. Compare the North West and Yorkshire:
Annual use | North West England | Yorkshire | Cheaper |
5,000 kWh | £1,491 | £1,505 | North West, by £14 |
10,000 kWh | £2,816 | £2,785 | Yorkshire, by £31 |
20,000 kWh | £5,465 | £5,345 | Yorkshire, by £120 |
The crossover sits at roughly 6,600 kWh a year, so a low-use kiosk and a busy café can rank the same two regions differently.
What are typical business electricity rates for a small business?
Regional gaps sit on top of a base rate, so here is the base. These are average rates received by Bionic from its supplier panel, including commission, for 1 to 8 September 2026, as published by MoneySuperMarket.
Business type | Annual use | Unit rate | Standing charge | Illustrative annual bill |
Micro business, fixed | 5,000 to 15,000 kWh | 26.4p | 91.3p a day | £2,973 at 10,000 kWh |
Small business, fixed | 15,001 to 25,000 kWh | 27.2p | 107.4p a day | £5,832 at 20,000 kWh |
Out of contract | Any | 40.0p | 254.0p a day | £4,927 at 10,000 kWh |
Other sources publish quite different averages, from about 21p (Purely Energy, indicative, August 2026) to about 29p per kWh for small businesses, depending on supplier mix, commission and meter type, so treat any single figure as a guide.
Your postcode matters, but your contract matters more
Back to our two cafés. Regional network costs explain about £309 of the gap between them. Now suppose the Nottingham café's fixed deal ends and nobody notices. Out-of-contract electricity averaged 40.0p a unit plus 254.0p a day in the same September panel, against 26.4p and 91.3p on a fixed micro business deal. At 10,000 kWh that is £4,927 instead of £2,973, an extra £1,954 a year.
Official statistics point the same way. DESNZ's June 2026 Quarterly Energy Prices put the average for the smallest non-domestic band, under 20,000 kWh a year, at 34.31p per kWh for the first quarter of 2026, as reported by Purely Energy. That average includes businesses on deemed and out-of-contract terms, which helps explain why it sits well above typical fixed-deal rates.
Supplier choice matters too. On our comparison table, the cheapest and dearest estimates for 10,000 kWh differ by £404. Put simply, your postcode sets the floor. Your contract and supplier decide how far above it you pay.
Seven ways to lower your small business electricity prices, wherever you are
Find your DNO area code. Read the first two digits of the long bottom line of your MPAN, then match them in the regional table above. It helps you sanity-check any quote.
Compare total annual cost. Multiply the unit rate by your yearly kWh, then add the standing charge times 365. As the North West and Yorkshire example shows, the winner can flip with usage.
Ask for a postcode-specific business electricity quote. National averages hide regional and meter differences. Have your latest bill and contract end date to hand.
Start comparing three to six months before renewal. Rolling onto deemed rates is the costliest mistake in this guide.
Ask what is actually fixed. Some contracts fix only the energy rate and pass network charges through as they rise under Ofgem's RIIO-3 price control, which we explain in our 2027 business electricity rates forecast. Check the wording before you sign.
Ask about commission. Since 1 October 2024, suppliers must display broker fees in the principal terms of non-domestic contracts, so ask any adviser to state theirs. Our comparison is free to use, because supplier partners pay us when you switch.
Check the postcode before you sign a lease. Opening a second site or moving? Ask for a quote for the new address first, because regional charges and meter type can change your rate.

Frequently Asked Questions
Do small business electricity prices vary by postcode?
Yes. Network charges differ across Great Britain's 14 DNO areas, and suppliers build them into your unit rate and standing charge. The effect is real but modest compared with contract type.
Which region has the cheapest business electricity rates?
On Ofgem's household regional data at 10,000 kWh, East Midlands is cheapest and Merseyside and North Wales dearest. Business rates differ, and rankings shift with usage, so get a quote for your own postcode.
Can I switch DNO to avoid regional charges?
No. Your DNO is fixed by your address. Switching business electricity suppliers changes who bills you and the margin added, not who owns the local network.
What information do I need for a business electricity quote?
Your business address, annual usage from a recent bill, your MPAN and your current contract end date. With those to hand, a quote takes minutes.
Does Ofgem cap small business electricity prices?
No. Ofgem's price cap applies to household default tariffs only. Business rates depend on wholesale markets, network charges, your credit profile and your contract.
Am I a small or micro business, and does it matter?
Ofgem counts you as a microbusiness if you use up to 100,000 kWh of electricity a year, or have fewer than 10 employees and low turnover. Since December 2024, small businesses, broadly those with fewer than 50 employees, can also take unresolved complaints to the Energy Ombudsman (Ecotricity summary of Ofgem's definitions).
Do these prices include VAT?
No. Business quotes and every figure in this guide exclude VAT, which is normally added at 20%. Very low users may qualify for a reduced 5% rate.
Final Words
Your postcode does change small business electricity prices, mostly through network charges you cannot switch away from. On Ofgem's regional data the widest gap is around £310 a year at 10,000 kWh, and the ranking shifts with how much you use. The bigger levers are yours: renew before your deal ends, compare total annual cost, and check what your contract actually fixes.
