The business sector performs the most R&D in the UK. In 2016, it performed £22.2 billion, representing 67% of total expenditure on R&D in the UK. This grew 6% from £21.0 billion in 2015.
The product groups with the largest R&D expenditure in 2016 were:
- pharmaceuticals (£4.1 billion)
- motor vehicles and parts (£3.4 billion)
- aerospace (£1.9 billion)
- computer programming and information service activities (excluding software development) (£1.8 billion)
- miscellaneous business activities (£1.3 billion)
- research and development services (£1.0 billion)
In 2015, the computer programming and information service activities group was the third largest with £2.5 billion. For 2016, R&D into software development has been separated from this group to be monitored individually.
