Transmission charges set to more than double
Ofgem expects the transmission share of a typical dual-fuel bill to climb from £44 in 2025 to £105 by 2030. That is a 140% jump driven by the biggest network build-out in decades. The money will ultimately appear on every household bill, so the scale of the increase matters now.
£70bn programme under scrutiny
Transmission owners are due to spend around £70bn between 2026 and 2031 on 94 projects in the Pathway to 2030 plan. EDF says construction costs have already risen two to three times since the original forecasts, while many new generation projects face multi-year connection delays. The company argues the original value-for-money case may no longer hold and wants a fresh strategic review published quickly.
Call for open cost data
At present there is no public tracker showing how individual project costs have changed or whether the need for each scheme remains the same. EDF is asking Ofgem and NESO to release detailed cost updates and progress data before the end of 2026, plus a live tracker that is refreshed regularly. Recent reports on rising bills show why households need clarity on every part of the price.
What happens next
Only three of the 26 largest schemes have full funding so far. Decisions on the rest are due in the coming months. We have linked the full EDF post in our energy section if you want the detailed recommendations: Gas electricity.
