This week's announcement of the revival of the large, undeveloped Buchan Horst oilfield by Jersey Oil & Gas highlights a significant and potentially unintended consequence of the UK's current tax policy. The project's development, paused due to government uncertainty, is now proceeding with a notable fiscal advantage.

Fiscal Incentives for New Development

With production scheduled for after 2030, the Buchan project will benefit from tax offsets of up to 84.3% on development spending. Furthermore, once operational, its revenues will be taxed at a rate of 40%. This structure creates what the operator describes as an "optimal" situation for long-term investments.

Government Policy and Unintended Consequences

This advantageous fiscal outcome appears at odds with the current Labour government's stated climate mandate, which includes banning new oil and gas exploration and addressing excessive profits. Despite industry lobbying to remove the Energy Profits Levy (EPL) during low oil prices, the government maintained this tax until 2030, after which the standard tax rate will be 40% (with a potential price shock mechanism).

The Resulting Incentive Structure

The policy creates a perverse incentive: for major new developments not starting before 2030, the capital-intensive build-out phase is subsidized at a higher rate, while the production phase will be taxed at a lower rate. This encourages companies to invest now but delay production until the more favorable 40% tax regime takes effect in 2030. Industry warnings about this exact scenario during 2024's policy uncertainty were not heeded.

Broader Implications

For a government needing to address fiscal deficits, the current arrangements mean that a larger potential tax take from delayed mega-developments like Buchan and Ithaca Energy's Cambo field will likely benefit the next government, which opinion polls suggest will be a different party. While the EPL continues to pressure existing production, the mismatch between fiscal regimes could prove a boon for these large, new projects.
