In 2023, UK tax expenditure on residential coal was recorded at approximately $24 million USD. From 2024 to 2028, projections indicate a consistent annual decrease, with values anticipated to drop to 17.65 million USD by 2028. This represents a year-on-year decline of 5.74% on average, with a cumulative annual growth rate (CAGR) of approximately -6.5% over the five-year period.

Future trends to monitor include:

Policy shifts towards renewable energy subsidies potentially accelerating coal phase-out.
Market responses to any government interventions in residential energy consumption patterns.
Technological advancements in renewable energy impacting coal dependency.
