Selling to the UK public sector follows different rules to private B2B. A trust can’t simply buy your medical device because a clinician likes it - it buys through a compliant route, and that usually means you must already be on the right framework. This guide covers how UK public procurement works now, the named routes for each sector, and the credentials you’ll need.

The Palace of Westminster - UK public procurement is governed centrally but bought through sector frameworks.

A framework is a pre-agreed list of approved suppliers a public body can buy from without running a full tender each time. Win a place on the right one and you become buyable; miss it and the best product in the room still can’t be purchased.

Key takeaways

  • In the UK public sector you sell through named frameworks, not direct pitches - get listed first or you can’t be bought.
  • The Procurement Act 2023 (in force 24 Feb 2025) reshaped the rules, with the Central Digital Platform as the new front door.
  • The route depends on your sector - NHS Supply Chain for medical, G-Cloud for cloud/SaaS, consortia (YPO, ESPO) for local government.
  • Get the recurring credentials (CDP registration, Cyber Essentials, social value) ready before you bid.

How UK public procurement works now

The rules changed materially in 2025. The Procurement Act 2023 came into force on 24 February 2025 - the biggest overhaul of UK public procurement in a generation - built around transparency, wider competition and social value.

Three things matter most for a supplier trying to break in:

Register on the Central Digital Platform

The new CDP is the front door. You enter your core company details once - free - and share them with each buyer, instead of re-keying the same information into every tender.

Find opportunities in the right place

Higher-value contracts are advertised on Find a Tender; lower-value ones on Contracts Finder. Most routine buying, though, happens through frameworks you must already be on.

Know the three framework types

Closed frameworks (fixed supplier list, being phased out), open frameworks (reopen periodically for new entrants), and Dynamic Purchasing Systems you can join at any time.

The central buying body, Crown Commercial Service, became the Government Commercial Agency in April 2026 - but the frameworks (G-Cloud and the rest) carry on under the new name.

Find your route to market

The right framework depends entirely on what you sell and who you’re selling to. Choose your sector to see the named routes, exactly how to get listed, and the credentials buyers will expect.

The credentials you’ll need either way

Whatever the sector, a recurring set of qualifications opens the door. Get these in place before you bid - several are now pass/fail.

Central Digital Platform

The mandatory supplier registration behind every public procurement. Do it first.

Cyber Essentials

Increasingly mandatory - Cyber Essentials Plus for cloud hosting and sensitive data.

Carbon Reduction Plan

A PPN-compliant plan is a pass/fail requirement on most public tenders now.

Social value & modern slavery

A minimum 10% social-value weighting, plus a Modern Slavery statement for larger firms.

Quality standards

Sector ISO standards (e.g. ISO 13485 for medical devices) and proof you can deliver.

Financial standing

Accounts and insurance to show you can carry the contract - checked at selection.

Frequently asked questions

How do I sell to the NHS?

Most medical devices and consumables are bought through NHS Supply Chain. You register on the Central Digital Platform and the Jaggaer portal, then bid when your product category goes out to tender. Genuinely innovative products can also join the Medical Technology Innovation DPS at any time.

Is G-Cloud open for new suppliers?

Not continuously. As of July 2026, G-Cloud 14 is the live framework; G-Cloud 15 applications closed on 30 January 2026 and it is expected to go live around September 2026. As an open framework it reopens to new suppliers at intervals - the next window is expected around spring 2028.

What changed under the Procurement Act 2023?

It came into force on 24 February 2025 - the biggest overhaul of UK public procurement in a generation. It simplifies procedures, centralises notices on the Central Digital Platform, and increases transparency and the weighting of social value.

What credentials do I need to bid for public sector contracts?

Typically registration on the Central Digital Platform, Cyber Essentials (Plus for cloud hosting), relevant ISO certifications, financial standing, and a social-value commitment. Several of these are now pass/fail requirements.
