Why Southern Wales pays what it pays
The unit rate is set mostly by wholesale costs, which are the same everywhere; the standing charge is set mostly by the local network. National Grid Electricity Distribution runs the wires in this region (every MPAN here begins with 21), and its allowed charges — plus the cost of keeping supply to sparsely populated areas — are what make Southern Wales the 8th-cheapest of the 14 regions for the electricity standing charge and 9th-cheapest for the unit rate. Check the first two digits of your MPAN with the MPAN decoder if you are near a regional boundary.
If you run a business in Southern Wales
None of these figures apply to a business supply. Non-domestic contracts are not capped, deemed rates after a contract ends are routinely 40–100% above the domestic cap, and the only protection is the contract you sign. The tariff benchmark shows where a business rate sits; a free 48-hour contract review finds the cheaper option.
