A tender is a formal invitation to submit a bid for a contract. In the UK public sector, when a government body, council, NHS trust or other public authority needs to buy goods, services or works above a certain value, they are legally required to advertise the opportunity and invite competing suppliers to submit proposals. This process is called tendering.
The word "tender" is used in two ways: the invitation itself (called a tender notice or Invitation to Tender) and the response a supplier submits (their tender bid or tender submission).
Most public sector tenders follow a structured process:
Public sector tenders are governed by procurement law. Above certain value thresholds, contracts must be advertised openly so any qualified supplier can bid. Private sector companies can issue tenders too, but they have no legal obligation to advertise them publicly.
UK public sector buyers include:
UK public procurement is worth over £300 billion a year. That represents millions of contracts for IT services, construction, professional services, cleaning, healthcare, training, and hundreds of other categories. For a supplier with the right capabilities, winning even one public contract can transform their revenue pipeline and open doors to framework agreements worth far more.
The key challenge is finding relevant tenders before the deadline. TenderSignal monitors UK public sector feeds daily and sends email alerts when matching opportunities are published. Browse open tenders or set up a saved search to start receiving alerts.
A tender is the invitation issued by the buyer; a bid is the supplier's response to that invitation. You receive a tender and submit a bid.
Any business, regardless of size, can respond to a public tender as long as it meets the minimum qualification requirements. The UK government has a specific target to direct spending to small and medium-sized enterprises (SMEs).
Above-threshold public tenders typically run for 4 to 12 weeks from publication to contract award. More complex procurements can take several months.
An Invitation to Tender (ITT) is the full set of tender documents issued to shortlisted suppliers, containing the specification, evaluation criteria, pricing schedules, and terms and conditions.
Yes. There is no legal minimum company size for public sector tendering. Some contracts set financial thresholds such as minimum turnover, but these vary by contract.
