Ofgem Main Estimate Memorandum 2026-27

From: Energy Security and Net Zero Committee

Summary

Ofgem's Main Estimate for 2026-27 requests £13.8 million in net Resource DEL and £16.5 million in Capital DEL. Resource spending fell 71% from the previous year's supplementary estimate, primarily due to £30 million in legal provisions not recurring. Capital DEL rose 228% to fund a potential lease event under IFRS 16. Net budgets remain unchanged from the Spending Review settlement.

Key findings

  • Resource DEL net spending of £13.8m represents a £33.7m (71%) reduction from 2025-26 supplementary estimate, driven mainly by non-recurring £30m legal provision
  • Capital DEL increased by £11.5m (228%) to £16.5m to support lease capitalisation under IFRS 16, with final terms expected summer 2026
  • Green Gas Support Scheme expenditure expected to increase to £91.0m but fully offset by higher Green Levy income; scheme is demand-led
  • Administration costs totalled £13.8m, down £25.8m from 2025-26 final budget but up £5.0m from 2025-26 main estimate due to depreciation funding
  • Depreciation charge of £21.3m reflects increased amortisation of intangible assets and higher lease depreciation charges
