Executive summary
Where you live has a real and often overlooked effect on your energy bill. This report maps unit rates and standing charges across all 14 UK distribution regions, quantifying the gap between the cheapest and most expensive areas for a typical household.
The differences are driven by network costs rather than supplier choice, meaning two identical homes on the same tariff can pay meaningfully different amounts purely because of their region.
Key findings
- The most expensive region can cost a typical household over £100 a year more than the cheapest.
- Standing charge variation is wider than unit rate variation between regions.
- Northern and rural network regions tend to carry higher distribution costs.
- Switching supplier does not remove regional cost differences — they are baked into network charges.
Why region matters
Each of the UK's 14 distribution network operators recovers its own costs, and those costs vary with geography, population density and infrastructure age. Suppliers pass these regional charges straight through to your bill.
This means the 'best deal' can differ by region, and national tariff averages can be misleading for households at the extremes.
