United Kingdom Procurement Act 2023: New Rules, Thresholds & CDP Registration 2026

The United Kingdom's public procurement landscape is undergoing its most significant transformation in decades. With the Procurement Act 2023 now firmly in place, effective from February 24, 2025, suppliers looking to secure government contracts in 2026 and beyond face a new set of rules, thresholds, and digital requirements. This comprehensive guide delves into the intricacies of this new framework, offering vital insights for bid managers, export managers, and procurement officers worldwide aiming to understand UK Procurement Act 2023 requirements and thresholds 2026, navigate the Central Digital Platform CDP registration for suppliers, and successfully bid for contracts in this dynamic market.

The Procurement Act 2023 replaces the Public Contracts Regulations 2015, along with other associated rules, for most central and devolved public bodies. This legislative shift aims to simplify, speed up, and make public procurement more accessible, while also delivering greater value for money and embedding social and environmental considerations. For anyone involved in tendering, understanding these changes is not just beneficial, it's essential for competitive success.

The Legal Framework: Procurement Act 2023 in Detail

The Procurement Act 2023 (c. 35) represents a fundamental reshaping of the UK’s public procurement regime. It applies to "public contracts" as defined in Section 3, specifically when the estimated value, inclusive of VAT, meets or exceeds the thresholds detailed in Schedule 1, and the contract is not exempt under Schedule 2. This Act is designed to create a more agile and transparent system, moving away from the EU-derived regulations that previously governed UK public spending.

The primary regulatory body overseeing this new framework is the Cabinet Office's Government Commercial Function (GCF), with the Crown Commercial Service (CCS) leading policy for central government procurement and framework management. While the Cabinet Office issues Procurement Policy Notes (PPNs) and guidance to support implementation, the Competition and Markets Authority (CMA) retains its role in addressing competition-related issues. This layered oversight ensures both strategic direction and fair play within the market.

One of the most noteworthy changes is the introduction of the Central Digital Platform (CDP). This platform is set to become the single source for publishing procurement notices, managing supplier information, and facilitating the new procurement procedures. It's an ambitious move towards a fully digital and integrated system, promising greater efficiency and accessibility for suppliers. Understanding how to register and operate within the CDP will be paramount for any organization targeting UK public contracts.

Understanding Bidding Thresholds for 2026

The financial thresholds that dictate which procurement procedures apply are crucial for suppliers. These amounts, effective from January 1, 2026, are set out in Schedule 1 of the Procurement Act 2023, as amended by the Procurement Act 2023 (Threshold Amounts) (Amendment) Regulations 2025 (SI 2025/1200). It’s important to note that all figures are inclusive of VAT.

For central government and NHS authorities, services and supplies contracts will be subject to the full Act's procedures if their value reaches £135,018. Non-central government authorities, such as local authorities, schools, and housing associations, face a slightly higher threshold of £207,720 for services and supplies. Works contracts, regardless of the authority, are subject to the Act at £5,193,000.

Utilities contracts also have distinct thresholds: £415,440 for services and supplies (other than works or light-touch), and £5,193,000 for works contracts. Light-touch services and supplies, as well as concessions, have their own specific thresholds, generally higher than standard services and supplies. These precise figures reflect the UK's commitment to aligning with updated WTO GPA thresholds, a change confirmed by PPN 023/2026 “Threshold Amounts.” Suppliers must meticulously check these values, as they determine the applicable procurement rules.

Below-Threshold Contracts and Simplified Procedures

Contracts falling below these stipulated values are considered "below-threshold" and are not subject to the full regulated procedures of the Act. However, this doesn't mean a free-for-all. Contracting authorities may still implement simplified or voluntary procedures to ensure fairness and transparency. Furthermore, Section 85 of the Act introduces specific rules for "regulated below-threshold contracts." For instance, certain works contracts valued above £135,018 or £207,720 but below the main works threshold must follow streamlined procedures. This ensures a degree of oversight and structure even for smaller contracts, preventing fragmentation and ensuring value for money. Suppliers interested in these smaller opportunities should still be prepared for some level of formal process, even if less stringent than for above-threshold procurements.

Central Digital Platform (CDP) Registration and Supplier Requirements

The Central Digital Platform (CDP) is poised to be the cornerstone of the UK's new digital procurement ecosystem. Replacing many functions previously handled by individual authority portals and the Contracts Finder service for above-threshold notices, the CDP will centralise notice publication, supplier information, and digital tendering. For any supplier wishing to participate in above-threshold procurements, registration on the CDP will be mandatory.

The registration process on the CDP is designed to gather essential supplier information and verify compliance. Typically, suppliers will need to provide detailed legal entity information, including company name, registration number, and address. Financial information and VAT numbers are also standard requirements. Furthermore, evidence of legal, economic, financial, and technical standing will be requested, often through pre-qualification questionnaires or PAS-91-style standard forms. This ensures that only capable and compliant suppliers are considered for contracts. A critical component of registration is the confirmation of compliance with exclusion grounds – meaning suppliers must declare they are not subject to issues such as insolvency, serious professional misconduct, or tax irregularities. The CDP aims to simplify this process by standardising data collection and reducing the need for repetitive submissions across different tenders. Suppliers can manage their organization profiles on platforms like TendersGo, which offers dedicated company information pages , helping them keep all their details organized and ready for submission.

Accepted Bidding Methods Under the New Act

The Procurement Act 2023 streamlines and modernises the bidding methods available to contracting authorities, aiming for greater flexibility and efficiency. Gone are some of the more rigid procedures of the past, replaced by clearer, more adaptable options.

The Open procedure remains a staple, allowing any interested supplier to submit a tender without prior selection. For more complex procurements, the Restricted procedure involves a prior selection stage, typically through a pre-qualification questionnaire, before inviting selected suppliers to tender. Where needs are less defined or innovative solutions are sought, the Competitive procedure with negotiation permits dialogue with selected bidders. A similar but distinct option is the Competitive procedure without negotiation , which shares similarities with the former "competitive dialogue."

Direct award is still an option, but strictly limited to specific circumstances such as extreme urgency, intellectual property rights, single-source situations, or when a prior procedure has failed. The Act also continues to support Framework agreements , which are multi-supplier arrangements established through competitive procedures, allowing for subsequent call-offs. Dynamic purchasing systems (DPS) are also retained, offering electronic systems where suppliers can join at any point during the framework's duration. Additionally, the new Act introduces more flexible "innovation partnerships" and "competitive flexible procedures" specifically tailored for complex or highly innovative procurements, reflecting a move towards fostering innovation within the public sector. Finding opportunities that align with these methods is made easier with tools like TendersGo, which allows users to filter tenders by procedure type , helping suppliers focus their efforts.

Required Documents and Evaluation Criteria for UK Tenders

Submitting a successful bid in the UK requires meticulous preparation of documentation. While specific requirements can vary based on the procedure and the contracting authority, a core set of documents is almost universally expected. These typically include a comprehensive tender submission form, responding directly to the tender documents. A detailed technical proposal is crucial, outlining the method statement, project plan, proposed staffing, and quality assurance measures. Equally important is the financial proposal, which should clearly present pricing, a cost breakdown, and VAT treatment.

Beyond these core submissions, suppliers must provide evidence of their legal, economic, financial, and technical standing. This often entails presenting company registration details, audited accounts, CVs of key personnel, professional references, and proof of adequate insurance. Declarations confirming compliance with exclusion grounds and selection criteria are also standard. For projects involving sub-contractors, their information will be required. Increasingly, authorities are also requesting environmental and social value statements, reflecting the Act’s emphasis on broader value-for-money principles. Many authorities are now adopting standardised forms, often aligned with PAS 91 or the CDP's digital forms, to streamline this process. Keeping all these documents organised and readily accessible is crucial, and platforms like TendersGo can assist by providing a secure place to store and access proposal components, especially when utilizing their B2B global marketplace to connect with potential partners or subcontractors.

Evaluation Criteria: Most Advantageous Tender (MAT)

The Procurement Act 2023 marks a significant shift in how tenders are evaluated. The previous "Most Economically Advantageous Tender" (MEAT) concept has been replaced by the "Most Advantageous Tender" (MAT). This change underscores a move beyond merely price-focused evaluation towards a more holistic assessment of value. Under MAT, evaluation must consider price or cost alongside other award criteria directly linked to the contract's subject matter.

Crucially, while price or cost must be evaluated, it is no longer necessarily the sole or dominant criterion. Award criteria can now encompass a broader range of factors, including quality, functionality, technical merit, and critically, environmental and social value. This means contracting authorities can give weight to aspects like carbon reduction, skills development, and local employment initiatives. Lifecycle costs and whole-life value assessments are also encouraged, promoting sustainable and long-term solutions. For transparency, all criteria must be objectively verifiable, proportionate, clearly stated in the procurement documents, and weighted or scored in a transparent manner. This new approach empowers authorities to procure not just goods and services, but also positive societal and environmental outcomes, creating opportunities for suppliers who can demonstrate strong commitments in these areas.

Foreign Bidder Tips for UK Government Tenders 2026

For international suppliers looking to enter the UK public procurement market, the Procurement Act 2023 presents both opportunities and specific challenges. The centralisation offered by the CDP is a significant advantage, providing a single portal for many above-threshold tenders. However, foreign bidders must pay close attention to several key areas to succeed.

Firstly, understanding the legal nuances of the Act and its supporting regulations is paramount. While the system aims for simplification, local legal and administrative practices can still differ. Seeking local legal counsel or engaging with experienced consultants can be invaluable. Secondly, fulfilling the CDP registration requirements meticulously is non-negotiable. This includes translating all necessary legal and financial documents into English and ensuring they meet UK standards. Third, demonstrate a clear understanding of the UK market context and the specific needs of the contracting authority. This extends beyond technical specifications to include social value and environmental considerations, which are increasingly weighted in evaluations. Foreign companies should consider how their operations can contribute to local communities, reduce carbon footprints, or support UK employment and skills development.

Finally, leveraging platforms like TendersGo can significantly aid foreign bidders . With its capacity to search for tenders across 220+ countries and translate documents in 145 languages, it breaks down geographical and linguistic barriers. The platform's AI-powered summaries can quickly distil complex tender documents, and unlimited email alerts ensure that relevant opportunities are never missed. Utilize TendersGo's advanced search and filtering to identify specific sectors or types of contracts relevant to your expertise, and make use of the PDF document viewer to review specifications efficiently. By combining these tools with a thorough understanding of the new UK procurement landscape, foreign bidders can position themselves strongly for success.

Complaint and Appeal Mechanism

Even with the best preparation, procurement processes can sometimes lead to disputes. The Procurement Act 2023 retains a robust challenge mechanism, allowing suppliers to contest procurement decisions. This system is largely similar to the remedies regime under the previous Public Contracts Regulations, now embedded within the new Act and its supporting regulations. Suppliers who believe a procurement process has been unfair or non-compliant can seek redress.

Key time limits apply, and understanding them is vital. A minimum 8-working-day "standstill period" is mandated between the notification of an award decision and the actual contract signature. This is a critical window for aggrieved parties to consider their options. Interim relief can be sought urgently if there is a risk of serious and irreparable harm. Any formal claim to the court must generally be made within 30 days of the date when the claimant knew or ought to have known of the grounds for challenge, though courts may grant extensions in specific circumstances. Challenges are brought in the High Court in England and Wales, or equivalent courts in Scotland and Northern Ireland. Remedies can include declarations of ineffectiveness, setting aside of decisions, damages, and in some cases, even the setting aside of the contract itself. This mechanism provides an important safeguard for fair competition and transparency within the UK's public procurement system.
