If two identical UK businesses with the same supplier on the same tariff get quoted different unit rates, the answer almost always sits in regional pricing. The same Octopus or Yu Energy SME contract is roughly 4p/kWh more expensive in SSEN North Scotland than in UKPN London — nothing to do with the supplier’s cost of energy and everything to do with the cost of moving electrons through the local wires.
This guide gives you the full 14-region DNO table for 2026, with example unit rates and standing charges, plus the structural reasons why some regions are stuck paying more. Run a free 60-second business energy quote to see what your specific MPAN gets — or read on to understand the map.
How regional pricing actually works
Your business electricity bill is built up from five layers, two of which are regional:
- Wholesale (~35-45% of bill) — same nationally.
- Transmission & balancing (~5-10%) — same nationally.
- Distribution Use of System (DUoS) (~10-15%) — regional. Set by Ofgem for each of the 14 DNO areas.
- Line losses (~3-5%) — regional. Higher in low-density and rural areas.
- Supplier costs & margin, levies, VAT — same nationally with minor variations.
DUoS plus losses is what creates the ~4p/kWh spread between cheapest and most expensive regions. Suppliers don’t set this — Ofgem does, every five years through the RIIO price control framework. As an end user you cannot negotiate it; you can only choose which side of the line your meter sits on (which usually means: where you choose to set up your business).
The UK has 14 DNO regions, run by 6 distributors
Six Distribution Network Operators (DNOs) own and run all 14 regional licence areas:
- UK Power Networks (UKPN): London, East England, South East
- Western Power Distribution (WPD): South West, South Wales, East Midlands, West Midlands
- Northern Powergrid (NPG): Yorkshire, North East
- Electricity North West (ENWL): North West (Manchester, Cumbria)
- SP Energy Networks (SPEN): SP Manweb (Merseyside & North Wales), SPEN Distribution (Central & South Scotland)
- SSEN (Scottish & Southern Electricity Networks): SSEN South (Southern England), SSEN North (Scotland)

Why London is the cheapest UK region
UKPN London is consistently the cheapest UK business electricity region for three reasons:
- Density. Metres of cable per kWh delivered is the lowest of any region. The fixed cost of distribution spreads across more units.
- Demand profile. Heavy commercial demand smooths the load curve, which lets UKPN run the network closer to capacity without expensive reinforcement.
- Embedded generation. Significant embedded solar, CHP and battery within the M25 reduces transmission imports and avoids “headroom” charges.
UKPN East and South East follow as the next-cheapest, both for the same density-and-demand reasons.
Why North Scotland is the most expensive UK region
SSEN North Scotland has the highest 2026 unit rates for business electricity for the inverse reasons:
- Geography. Long thin network covering the Highlands & Islands. Far more cable per kWh delivered than any other region.
- Low demand density. Sparse customer base means fixed network costs spread across fewer kWh.
- High line losses. Power generated in the north has to travel further, with proportionally bigger losses, before it reaches a customer.
- Renewable export congestion. The network was built for north-to-south flows from Scottish hydro and wind; the economics work, but the infrastructure investment is significant and feeds into DUoS.
Per-region drill-down
UKPN London (Greater London)
Cheapest UK region. Example SME unit rate: 23.5p/kWh, standing 50p/day. Best deals for <5k kWh micros: ~22p/kWh from Octopus or Yu Energy.
UKPN East England (East Anglia, Bedfordshire, Hertfordshire)
Second cheapest. Example SME rate: 24.2p/kWh, standing 52p/day. Strong embedded solar in this region keeps DUoS competitive.
UKPN South East (Kent, Surrey, Sussex)
Third cheapest. Example SME rate: 24.6p/kWh, standing 53p/day. Cross-channel interconnector imports help keep transmission costs in check.
WPD East Midlands (Derbyshire, Nottinghamshire, Lincolnshire, Leicestershire)
Mid-band. Example SME rate: 25.0p/kWh, standing 54p/day. The WPD network is one of the most efficient in the country — rates are mid only because density is lower than London.
WPD West Midlands (Birmingham, Black Country, Shropshire)
Mid-band. Example SME rate: 25.3p/kWh, standing 55p/day. Heavy industrial load helps DUoS scale.
WPD South West (Cornwall, Devon, Somerset, Bristol)
Mid-band. Example SME rate: 25.4p/kWh, standing 55p/day. Significant embedded solar, but lower density pushes rates above the East Mids.
NPG Yorkshire (Yorkshire, parts of Lincolnshire)
Mid-band. Example SME rate: 25.6p/kWh, standing 56p/day. Mixed industrial/domestic profile.
SSEN South (Hampshire, Berkshire, Oxford, Wiltshire, Dorset)
Mid-band. Example SME rate: 25.7p/kWh, standing 57p/day. Different DNO from northern Scotland despite the SSEN name.
WPD South Wales (Cardiff, Swansea, Newport, valleys)
Mid-band. Example SME rate: 25.8p/kWh, standing 56p/day. Lower density and dispersed demand.
NPG North East (Tyne & Wear, Durham, Northumberland, Teesside)
Mid-high. Example SME rate: 26.1p/kWh, standing 58p/day. Heavy industrial decline of last decade has reduced demand density.
ENWL North West (Greater Manchester, Lancashire, Cumbria)
Mid-high. Example SME rate: 26.4p/kWh, standing 59p/day. Cumbria’s rural network and Manchester’s urban core average to mid-high.
SPEN Distribution (Central & South Scotland)
High. Example SME rate: 26.7p/kWh, standing 60p/day. Mostly Edinburgh/Glasgow corridor; wind generation export charges feed into DUoS.
SP Manweb (Merseyside, Cheshire, North Wales)
High. Example SME rate: 26.9p/kWh, standing 61p/day. North Wales’ rural geography pulls rates up despite Liverpool/Cheshire’s urban density.
SSEN North (Highlands, Islands, Inverness, Aberdeen, Dundee)
Highest. Example SME rate: 27.6p/kWh, standing 65p/day. Geographic challenges keep this region top of the table every year.
How to use this knowledge
You can’t change your DNO without moving premises. What you can do:
- Quote real rates. Use a Letter-of-Authority-driven comparison so quotes reflect your actual MPAN, not a regional estimate.
- Negotiate within-region. The 30-50% cheapest-vs-most-expensive supplier spread within your region matters far more than the 15% cross-region spread.
- Check meter-level details. Profile class (PC03, PC04, etc.), meter timeswitch class and connection capacity all affect rate even within a region.
- Apply the right contract length. See business energy tariffs for length guidance in 2026.
- For multi-site portfolios spanning multiple regions, run an aggregated tender; suppliers offer 0.5-1.5p/kWh discounts for multi-site users. See multi-site business energy meters.

Frequently Asked Questions
The 2026 spread between the cheapest UK region (UKPN London at ~23.5p/kWh) and the most expensive (SSEN North Scotland at ~27.6p/kWh) is roughly 4p/kWh for an SME on a 24-month fix at 30,000 kWh annual usage. Standing charges also vary, from 50p/day in London to 65p/day in northern Scotland.
UKPN London is cheapest because of high density (lower DUoS per kWh delivered), heavy commercial demand that smooths the load curve, and significant embedded solar / CHP / battery within the network. The same supplier on the same tariff prices about 4p/kWh lower in London than in northern Scotland.
SSEN North covers the Highlands & Islands — long, thin network with low demand density and high line losses. The fixed cost of network maintenance spreads across fewer kWh, which inflates DUoS. North-to-south renewable export charges also feed into the regional rate.
No — DUoS and line losses are set by Ofgem under the RIIO price control framework, not by suppliers. What you can negotiate is the supplier’s margin, the wholesale lock and broker uplift. The within-region 30-50% spread between cheapest and most expensive supplier is where the negotiating happens.
The first two digits of your MPAN profile are the DNO ID code (10=East England, 11=East Midlands, 12=London, 13=Merseyside & N Wales, 14=Midlands West, 15=North East, 16=North West, 17=North Scotland, 18=South Scotland, 19=South East, 20=Southern, 21=South Wales, 22=South West, 23=Yorkshire). Your supplier or any LOA-driven comparison will identify it for you automatically.
Gas regional variation is much smaller than electricity — typically under 0.5p/kWh between cheapest and most expensive Local Distribution Zone (LDZ). That’s because gas distribution charges are flatter across the UK and there are no equivalent line losses. Your postcode mostly affects electricity, not gas.
