Methodology note
Restart new oil and gas licences: calculation note
Scenario assumptions behind the Restart new oil and gas licences estimate. The figures are illustrative and exclude unrelated Conservative pledges.
Central fiscal result
+GBP 0.1bn - Net fiscal impact in 2028-29
Low case: -GBP 1.0bn. High case: +GBP 2.0bn. Positive numbers are fiscal costs or borrowing pressure. Negative numbers are Exchequer savings or receipts.
Scenario and baseline
- Model new North Sea licensing from 2026-27 onward.
- Central fiscal effect is near zero by 2028-29.
- Baseline is declining North Sea receipts and current tax rules.
- Energy Profits Levy repeal is modelled separately.
Affected population
- Affected population is oil and gas producers and supply chains.
- Direct exposure includes licensed operators and contractors.
- Indirect exposure includes emissions budgets and local workforces.
- Household bill exposure is indirect and limited.
Gross impact
- Central: licensing administration costs roughly offset early receipts.
- Low case assumes some extra bonus, fees and investment receipts.
- High case assumes tax reliefs and decommissioning exposure dominate.
- No consumer-price saving is scored.
Fiscal build-up, central case
- Licensing and administration: +GBP 0.1bn
- Early tax and fee receipts: -GBP 0.2bn
- Investment reliefs and allowances: +GBP 0.2bn
- Decommissioning and monitoring: GBP 0.0bn
Central net impact: +GBP 0.1bn in 2028-29.
Behaviour and pass-through
- Low case assumes commercially viable fields and higher prices.
- Central case assumes long lead times and limited near-term output.
- High case assumes tax reliefs exceed receipts by 2028-29.
- Investment may be deterred by policy uncertainty.
- Energy security benefits are not treated as fiscal receipts.
Phasing
- 2026-27: GBP 0.0bn. Preparation or partial implementation.
- 2027-28: GBP 0.0bn. Main ramp-up year.
- 2028-29: +GBP 0.1bn. Target-year central estimate.
- 2029-30: +GBP 0.1bn. Continuation at steady-state assumptions.
