Procurement Across Sectors
Public, private and third-sector organisations all buy goods and services, but they pursue different objectives and answer to different stakeholders. In L4M1, do more than list differences: explain how the sector's purpose, funding and accountability change the procurement approach.
Public-sector procurement
Public bodies spend public money and therefore operate with formal rules, transparency and auditability. In England, Wales and Northern Ireland, the Procurement Act 2023 came into force on 24 February 2025, replacing the former PCR 2015 regime for the procurements within its scope.
Section 12 requires contracting authorities to have regard to four objectives:
- delivering value for money;
- maximising public benefit;
- sharing information to support understanding and oversight; and
- acting, and being seen to act, with integrity.
Fair treatment and non-discrimination are separate duties. In an answer, avoid describing them as a fifth section 12 objective.
Competition and supplier participation
The Act provides two competitive procedures:
| Procedure | When it fits | Procurement logic |
|---|---|---|
| Open procedure | A clear, straightforward requirement where wide competition is suitable. | Any interested supplier can tender; documents are published together and compliant bids are evaluated. |
| Competitive flexible procedure | A complex, innovative or risk-sensitive requirement where the authority needs to design stages, narrow participation, hold dialogue or negotiate. | The authority designs a transparent procedure that fits the requirement. |
In a public procurement, conditions of participation test proportionate supplier capability, such as relevant experience, financial standing or technical capacity. A Procurement Specific Questionnaire (PSQ) can gather that information where useful. Requirements should reflect the contract's scale and risk; excessive thresholds can exclude capable SMEs and weaken competition.
Notices, award and standstill
The Find a Tender Service (FTS) is the UK publication service for the relevant regulated opportunities and notices; OJEU is not the current UK route. A public award is made to the Most Advantageous Tender (MAT), not the former MEAT terminology. MAT permits consideration of price, quality, whole-life cost, sustainability, social value, innovation and the needs of service users where the published criteria support them.
After the relevant contract award notice, an 8-working-day standstill applies before contract conclusion. It gives unsuccessful bidders an opportunity to understand and, where appropriate, challenge the decision before the contract is entered into.
Why the public approach differs
Public buyers need a process that can withstand scrutiny because they use taxpayer money and pursue public outcomes as well as commercial value. Transparency, equal treatment and documented evaluation therefore protect both competition and public confidence. That can make procurement slower than a private purchase, but it reduces the risk of arbitrary awards and poorly supported decisions.
Private-sector procurement
Private organisations generally procure to support commercial performance, continuity, growth and shareholder or owner value. They are not normally subject to the Procurement Act 2023's mandatory tendering process, although contract law, competition law, anti-bribery law, data protection and sector-specific regulation still apply.
The buyer can usually choose the process, confidentiality level, supplier engagement and pace. Direct negotiation may be commercially sensible where speed, innovation, existing capability or a strategic relationship warrants it. The trade-off is that the organisation needs internal controls strong enough to prevent conflicts of interest, fraud, unmanaged supplier risk or poor value.
Private-sector sourcing also faces pressure from customers, investors, lenders, employees and regulators. ESG expectations, modern-slavery transparency obligations where applicable, and supply-chain resilience can affect supplier selection even where no public-procurement rule applies.
Third-sector procurement
Charities, NGOs, social enterprises and community organisations procure to deliver a social, environmental or community mission rather than distribute profit. Their funding may include grants, donations and trading income, and they are accountable to beneficiaries, donors, trustees and relevant regulators.
Resources and specialist procurement capacity can be limited, while reputational expectations are high. An organisation spending public grant money may also be required by its funder to follow specified procurement rules. Procurement consortia can help third-sector organisations gain purchasing leverage, standard contracts and specialist support without building a large internal team.
Compare the sector before recommending an action
| Question | Public | Private | Third sector |
|---|---|---|---|
| Main purpose | Public benefit and value for money | Commercial performance and competitive advantage | Mission delivery and stewardship of funds |
| Accountability | Public, audit and legal scrutiny | Owners, board, investors and customers | Trustees, donors, beneficiaries and regulators |
| Process | Formal and transparent within the legal regime | Chosen to fit commercial need and risk | Often funder- or mission-led; capacity may be constrained |
| Award focus | Published MAT criteria | Best justified commercial outcome | Mission alignment, value and responsible use of funds |
Essay application
If a question asks why sector affects procurement, use a cause-and-effect structure. For example, public accountability leads to transparent notices, published criteria and a standstill period; private commercial confidentiality can permit faster negotiation; third-sector stewardship can favour collaboration and proportionate controls. Apply the comparison to the facts in the scenario rather than describing every sector regardless of the command word.
