How this ranking works
- Data source: official UK government contract award notices.
- Period: award notices published between 1 January and 31 December 2026. The data for this year so far covers March to September (earliest award 13 Mar 2026, latest 29 Sept 2026), so the ranking will change as the year goes on.
- What counts: each award notice naming the company as supplier. Only limited companies and LLPs are listed.
- Order: number of award notices, then total stated award value where two companies have the same number.
- Values are as stated in the notices. Many notices do not state a value, so totals are often incomplete.
- No company can pay to change its rank. Any paid placement is shown separately and labelled "Promoted".
- Data last updated: 29 Sept 2026.
