Ofgem Should Admit Electricity Prices Will Remain Elevated for Years, Says Nils Pratley

AI Summary
Energy regulator Ofgem is expected to keep the electricity price cap high as wholesale and non‑commodity costs surge. Analysts warn that without medium‑term forecasts, consumers and industry face a decade of costly power bills.

Britain’s energy regulator is poised to announce another steep quarterly price‑cap, signalling that electricity bills will stay high for the foreseeable future. The rise is driven not just by volatile wholesale prices but by a cascade of non‑commodity costs that are set to balloon over the next decade.

Why the Next Ofgem Price Cap Is Likely to Remain Elevated

Energy consultant Cornwall Insight predicts the typical household electricity bill will reach £1,850 this quarter – an increase of £209 from the previous period. The regulator’s messaging will likely cite the ongoing disruption of the Strait of Hormuz and the mitigating effect of new wind and solar generation.

Cost Drivers Behind the Rising Electricity Bills

  • Wholesale electricity now accounts for only 30% of the bill, down from 90% a few years ago.
  • Non‑commodity charges – grid upgrades, carbon taxes, warm‑home discounts and nuclear subsidies – dominate the cost structure.
  • Network Use of System charges are projected to jump from £7.6bn this year to £12.1bn by 2029‑30, a ~60% increase.
  • Balancing costs could rise from £2bn annually now to as much as £8bn by 2030.
  • Industry leaders warn that even a 50% cut in wholesale prices would still leave bills 20% higher due to fixed non‑commodity costs.

Broader Economic and Industrial Implications

High electricity prices threaten UK manufacturing competitiveness, as highlighted by the CBI and Energy UK. The Climate Change Committee stresses that cheaper power is essential to accelerate heat‑pump and electric‑vehicle adoption, yet the current cost trajectory delays those decarbonisation gains.

What Transparent Medium‑Term Forecasts Could Change

Analyst Ben James estimates an average increase of £79 per household between 2025 and 2030. If Ofgem published similar medium‑term models, policymakers could better allocate levies, decide on taxation versus direct subsidies, and provide households with clearer expectations. Greater openness would also sharpen the political debate on who should bear the rising grid and balancing costs.
