What Are Public Sector Tenders? A Plain-English Introduction

A "public sector tender" is simply the formal process a government body uses to buy something. Anything a council, an NHS trust, a police force, a university, or a central government department needs - from IT systems and construction work to catering, consultancy, or cleaning services - usually has to be bought through a competitive, published process rather than picked from a supplier the buyer already knows.

That requirement exists for a simple reason: public bodies spend public money, so the rules are designed to make sure they get fair value and that any capable business gets a genuine chance to compete, not just whoever the buyer already has a relationship with.

What actually gets published

When a public body wants to buy something above a certain value, it publishes a contract notice - a structured listing describing what's needed, roughly how much it's worth, the deadline to respond, and how to find the full tender documents. In the UK these notices are published on a small number of official platforms, principally Find a Tender (for higher-value contracts, since the UK left the EU's OJEU/TED system) and Contracts Finder (which covers a much wider range of values, including many contracts too small to require Find a Tender). Devolved administrations run their own platforms too - Public Contracts Scotland and Sell2Wales are the Scottish and Welsh equivalents.

Why so many different platforms?

Partly history, partly devolution. Each nation and sector has built its own system over time, and there's no single UK-wide search engine that reliably covers all of them (we wrote a separate post comparing the main ones). In practice, a business that only checks one platform is very likely missing genuine opportunities it would actually be a good fit for - which is the entire reason a tool like this one exists: it watches all of them in one place and matches notices against keywords you actually care about, rather than you checking four different websites by hand.

Who can bid?

In principle, any business that can demonstrate it can deliver the contract. Some tenders set minimum requirements - financial standing, relevant experience, insurance levels, technical capability - but there is no general rule that only large companies can bid. Plenty of contracts, especially below the higher thresholds, are won by small and medium-sized businesses and sole traders every year.

What's next

If this is new territory, our next post walks through how to actually apply for a public tender, and this one covers how the UK procurement process works end-to-end, including the rules public bodies themselves have to follow.

Public procurement rules and thresholds are set by law and updated periodically - always check the current guidance on gov.uk for anything you're relying on to bid.
