The UK government's intramural R&D expenditure, expressed as a percentage of GDP, experienced forecasted declines from 2024 to 2028: beginning at 0.1% in 2024, then steadily decreasing to 0.09% by 2028. This downward trend reflects slight year-on-year decreases. As of 2023, the actual expenditure value stood at 0.1% of GDP. Over this five-year span, the compound annual growth rate (CAGR) exhibits a moderate reduction, illustrating a cautious outlook for government R&D investment relative to GDP in the near term.

Future trends to watch include:

Potential shifts in government policy that might impact funding allocations.
The influence of economic conditions on overall GDP and subsequent R&D expenditure realignment.
Technological advancements requiring strategic R&D investments in emerging sectors.
