Why electrification matters now
Recent Middle East events have pushed up gas and oil prices again, underlining how exposed UK households remain to fossil fuel swings. EDF points out that electrified homes feel far less impact: a 30% rise in gas and oil prices lifts annual bills by just 1.7% for all-electric households versus 13.5% for dual-fuel homes. EV drivers already save more than £1,100 a year on fuel compared with petrol cars. The firm says the long-term fix is wider uptake of heat pumps, EVs and other low-carbon tech, which spreads the cost of new generation and networks across more users.
The timing tightrope for networks
Local distribution networks must be upgraded to handle extra demand from heat pumps and chargers, yet Ofgem’s next price control (RIIO-ED3, 2028-2033) must avoid loading costs onto bills before enough homes have switched. Around 4 million homes sit on looped supplies that slow new connections. Ofgem wants DNOs to follow the transitional Regional Energy Strategic Plan, but EDF warns the plan’s heat-pump and EV forecasts look optimistic given current adoption trends and recent policy reviews. Invest too early and bills rise prematurely; invest too late and households face connection delays.
What needs to change
We think the right balance starts with stronger incentives for households to adopt low-carbon tech, building on existing grants and the Warm Homes Plan. Ofgem should also give more weight to real-world market data when it reviews DNO business plans later this year, and publish clear forecasts of how network costs will hit customer bills. Recent government moves have already trimmed average bills by £150, yet long-term affordability still hinges on aligning investment with actual demand. We covered the ongoing pressure on household bills last month.
