In 2023, the UK's tax expenditure on fossil fuel production stood at an unspecified value, while forecast data from 2024 to 2028 projects a consistent increase, starting at $7.01 billion in 2024 and rising to $7.87 billion by 2028. This represents a steady year-on-year growth, with percentage increases expected to gradually rise from 2024 until 2028.

Future trends to watch for include:

The continued impact of policy changes on the fossil fuel industry's tax benefits.
Global shifts towards renewable energy which may affect these expenditures.
Adjustments within the UK's fiscal and environmental strategies that could influence these forecasts.
