Procurement Act 2023: what changed

The Procurement Act 2023 is the biggest overhaul of UK public procurement in a generation, replacing the old EU-derived regime with a single new framework. This is a plain-English summary of what changed and — more usefully — what it means for how you bid.

Why the rules changed

Following EU exit, the UK consolidated a patchwork of regulations into one regime with stated aims: make procurement simpler and more flexible, open it further to SMEs and social enterprises, sharpen value for money, and increase transparency. The intent is a system that’s easier to navigate for buyers and suppliers alike while holding both to higher standards of openness.

The new principles

The Act sets out objectives buyers must have regard to — including value for money, maximising public benefit, sharing information transparently, and acting with integrity. For bidders, the emphasis on public benefit reinforces the trajectory that’s made social value so central: contracts are increasingly judged on their wider impact, not just price and technical compliance. Our social value writing and the social value guide matter more under this framing, not less.

One central platform

A central digital platform underpins the new regime, with suppliers able to register core information once and reuse it, and opportunities and notices published through a single transparent system. The aim is less duplication — no more re-keying the same company details into every portal — and a clearer, single window onto the pipeline. For suppliers, getting your central registration and core data right is now foundational housekeeping.

MEAT becomes MAT

One change you’ll see in tender language: the award basis shifts from MEAT (Most Economically Advantageous Tender) to MAT (Most Advantageous Tender). The dropped “Economically” is deliberate — it signals that award can weigh wider value, including social and environmental benefit, more explicitly alongside cost. In practice it reinforces what good bidders already do: compete on demonstrable value, not just price. Our guide to how tenders are evaluated covers how this plays out in scoring.

Simpler procedures

The Act streamlines the available procedures — broadly, a flexible competitive procedure that buyers can design around the contract, plus an open procedure for simpler buys. The intent is to cut process complexity and give buyers room to run proportionate competitions. For suppliers it means tender structures may vary more between buyers, so reading each procurement’s specific rules carefully matters even more than before.

More transparency — and scrutiny

The regime introduces more notices across the contract lifecycle — from planning and pipeline through award to performance — and stronger provisions on supplier performance and exclusions, including published information on underperforming suppliers. The upside for good suppliers is a clearer pipeline to plan against; the discipline is that delivery now carries more visible reputational weight. Win on promises you can’t keep and the consequences are more public than they used to be.

What bidders should do

• Get registered properly on the central platform and keep your core supplier information current and accurate
• Watch the notices — richer pipeline information means earlier sight of opportunities; build it into your planning (our free tender scanning does this for clients)
• Lean into value — with MAT and public benefit foregrounded, strong social value and outcome evidence matter more than ever
• Read each procedure carefully — more buyer flexibility means less standardisation; don’t assume the format of the last tender
• Deliver what you promise — performance is more visible, so credibility compounds and overpromising bites harder

The fundamentals of winning bids haven’t changed — answer the question, evidence everything, write for the evaluator. The Act changes the plumbing and sharpens the emphasis on value and transparency; bidders who were already doing the basics well are well placed under it.

What stays exactly the same

Amid the reform, it’s worth saying clearly what the Procurement Act 2023 does not change, because anxious bidders sometimes assume everything is new. The fundamentals of winning are untouched. Buyers still publish award criteria and weightings; you still have to answer the question actually asked, evidence every claim, and write in a way evaluators can score and defend. Quality is still scored on a scale, price still by formula, and the highest weighted total still wins. A bid that was excellent under the old regime — specific, evidenced, compliant, written for the evaluator — is excellent under the new one. Everything in our guide to writing a winning bid and our breakdown of how tenders are scored applies just as it did before.

Practical first steps under the new regime

If you do one thing in response to the Act, make it this: get your supplier information right on the central digital platform and keep it current. The reform’s register-once philosophy only saves you time if your core data is accurate and complete to begin with, and a clean central profile becomes the foundation every future bid builds on. Beyond that, lean into the richer notice pipeline — the Act’s transparency provisions mean earlier, fuller sight of upcoming opportunities, which is a planning gift for organised bidders and the basis of effective pre-bid positioning. And take the heightened emphasis on value and public benefit seriously: with the award basis explicitly broadened to the Most Advantageous Tender, strong, credible social value is no longer a section to scrape through but a genuine route to the marks that decide close competitions. The buyers who designed the new regime want value and transparency; the suppliers who give them both, convincingly evidenced, are the ones it rewards.
