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 January to November (earliest award 2 Jan 2026, latest 13 Nov 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: 14 Nov 2026.
