What is Transforming Public Procurement?

The Transforming Public Procurement (TPP) programme aims to change how public procurement in the United Kingdom is regulated.

Our exit from the European Union presented the government with an opportunity to develop and implement a new procurement regime. 

Transforming Public Procurement is the name given to this programme. 

This page aims to clarify what TPP means for our customers and what information and training is available.

To find out how we are preparing for the upcoming regulation change, read our guide

The Cabinet Office is leading the Transforming Public Procurement programme. 

The new Procurement Act 2023 received Royal Assent in October 2023. A working go-live date for the new regime is currently 28 October 2024. This date will be formalised in Commencement Regulations which we expect to be made in May 2024.

In March 2024 the Procurement Regulations 2024 were laid in Parliament to bring some elements of the Bill and the wider regime into effect. This statutory instrument (SI), a form of secondary legislation, is available to view

To find more detailed information on how to prepare for the implementation of the regime, visit the Cabinet Office Transforming Public Procurement webpage.

Your questions answered

What is Crown Commercial Service’s role in TPP?

The implementation of TPP is led by the Cabinet Office. Crown Commercial Service does not own the Act or the associated training packages.

However, Transforming Public Procurement effects CCS in 2 important ways:

  1. as a public procurement organisation, we must make sure that when the new regulations go live, our agreements are let under these regulations
  2. as a contracting authority ourselves, we must prepare our organisation and ensure we can run robust procurement under the new regime

When does Transforming Public Procurement come into force?

The Procurement Act is the name given to the legislation that will reform the existing rules. It received Royal Assent in October 2023. 

Secondary legislation was laid in March 2024, with an estimated go-live date for the new regime in October 2024.

For Crown Commercial Service customers, this means that agreements which release their Invitation To Tender (ITT) on or after the go-live date will be let under the new regime.

Agreements that released their ITT before this date will be governed by the existing Public Contract Regulations (PCR2015) and will continue unchanged for their lifecycle.

Where can I find out about the Bill’s progress?

The Procurement Bill, has now received Royal Assent. 

You can view the new Procurement Act on the UK legislation website, and the official record of the Bill’s progress through Parliament, with all supporting documents on the Parliamentary website.

Where can I access training materials?

The Cabinet Office is responsible for the learning and development programme to support those operating within the new regime, available for free.

Find out more about the learning and development on the Cabinet Office TPP hub.

How can I keep up to date with what is on CCS commercial pipeline?

Awarding commercial agreements under the new regime will be new for everyone – including us at CCS.

This means our pipeline of commercial agreements going out under the new regime is likely to change because CCS is implementing the new regime at the same time as undertaking our normal activities. We will be continually reviewing and amending the priority list. To ensure you are using the latest information in any decision making, we recommend you check back regularly.
