Public bodies — councils, NHS trusts, government departments — buy tens of billions of pounds of goods and services every year, and they must do it in the open. That makes public-sector tendering one of the most reliable growth channels a business can build. But it has its own process, its own vocabulary and its own rules, and winning starts with understanding them. This guide walks you through all three.
The tendering lifecycle
Almost every public procurement runs through the same stages in the same order. Learn the stages and most of the jargon falls into place — it nearly all refers to a document or decision that belongs to one specific step.
-
1
Need identified
The buyer decides it needs to buy something. Above a value threshold this triggers a formal, published procurement; below it, a quote or direct award may be allowed.
-
2
Notice published
The buyer publishes a contract notice to the official procurement portals. This is the moment the opportunity becomes public.
-
3
Express interest
You register interest on the buyer's portal — this unlocks the full tender documents. Miss the expression-of-interest deadline and you can lose access before you have even started.
-
4
Selection (SQ / PQQ)
For larger contracts you complete a Selection Questionnaire proving you're solvent, compliant and capable. Smaller contracts skip this and go straight to the tender.
-
5
Tender (ITT) submitted
Shortlisted suppliers submit a full Invitation to Tender response — technical answers, method statements, pricing and references. This is the actual bid.
-
6
Evaluation
The buyer scores each bid against published criteria. Under the Procurement Act 2023 the default is Most Advantageous Tender (MAT) — price and quality plus social value and innovation, with weightings disclosed up front.
-
7
Award + standstill
Winners and losers are told and an award notice is published. A standstill period (8 working days under the new Act) lets unsuccessful bidders challenge the decision.
-
8
Contract starts
After standstill the contract is signed and work begins. The award notice stays public, so competitors can see who won, for how much and for how long.
Should you bid? A qualification checklist
A serious bid can take days of skilled effort, so qualify hard before you commit. Work through these before you write a word — a disciplined bid/no-bid decision is the single biggest driver of your win rate.
Am I eligible?
Meet every mandatory requirement — minimum turnover, financial checks, insurances, references, certifications. If you can't clear a mandatory bar, walk away now.
Do I have the right experience?
Buyers score evidence of similar, similar-size delivered work. No comparable evidence — and no partner who has it — means an uphill fight on quality questions.
Have I the capacity to deliver?
Could you staff and resource this alongside current commitments? Winning a contract you can't deliver is worse than losing it.
Is the price worth it?
Know your margin on this scope, and how your price sits against likely rivals. Read the model contract's payment terms and liability caps before you quote — they move your real margin.
What changes if I win?
New staff, equipment, premises, accreditations — and can you sustain them when the contract ends? Factor the ramp-up into the decision.
Can I submit real quality?
A rushed, cut-and-paste bid rarely scores. If you can't give it the time to mirror the scoring rubric with specific, evidenced answers, spend that effort on a tender you can win.
The jargon, translated
- SQ — Selection Questionnaire
- Standard form covering company info, exclusion grounds, financial standing and technical capability. Used to shortlist suppliers before the main tender.
- PQQ — Pre-Qualification Questionnaire
- The older name for the SQ. Some buyers still use it; same purpose.
- ITT — Invitation to Tender
- The main tender pack — instructions, technical questions, pricing schedule and evaluation criteria. Your full bid responds to it.
- RFP — Request for Proposal
- A less formal invitation with some room for creativity; functionally similar to an ITT.
- RFQ — Request for Quotation
- Used when the buyer knows exactly what they want and just needs a price — a standardised product or service that's easy to compare.
- EOI — Expression of Interest
- Registering that you intend to bid, often to unlock the documents. You're not committed and can drop out later.
- MAT — Most Advantageous Tender
- The Procurement Act 2023 default. Drops MEAT's "economically" to signal price isn't automatically dominant — social value and innovation are first-class scoring factors.
- Framework
- A standing agreement with several pre-approved suppliers. Individual contracts ("call-offs") are run faster within it — a mini-competition or a direct award.
- DPS / Dynamic Market
- Like a framework but always open — suppliers can join any time. The Act replaces the old DPS with the more flexible Dynamic Market.
- Standstill
- The mandatory pause between award decision and signature (8 working days under the Act). Losing bidders can challenge only in this window.
- CPV code
- Common Procurement Vocabulary — a numeric category code on every tender (e.g. 72 = IT services). The reliable way to filter by sector.
- Social value
- A scored component (often ~10%) covering economic, social and environmental benefit beyond the contract itself. Weighted more heavily under MAT.
What the Procurement Act 2023 changed
The biggest reform in 20 years went live on 24 February 2025, replacing the Public Contracts Regulations 2015. It applies to any procurement started on or after that date; older ones run under the previous rules. The headline changes for bidders:
- ✓Three procurement routes, not seven — open, competitive flexible, and direct award.
- ✓MAT replaces MEAT — social value, environmental impact and innovation are now first-class scoring factors alongside price and quality.
- ✓Central Digital Platform — register your company details once; buyers reuse them instead of asking the same SQ questions every time.
- ✓Pre-tender signals at scale — buyers now publish pipeline, prior-information and market-engagement notices in huge numbers (almost as many as actual tenders). Engaging before a tender opens is the single biggest advantage available to a supplier.
- ✓Stronger SME duties — buyers must consider and remove barriers to smaller suppliers, and justify contract sizes that exclude them.
- ✓Public debarment list — serious performance failure or fraud can bar a supplier across all public buyers.
- ✓Standstill is now 8 working days (was 10 calendar days) — track award dates carefully.
Your biggest edge: engage before the tender opens
Those pre-tender notices tell you what a buyer plans to procure — often months ahead. That's your window to introduce your company, understand their priorities, and help shape the requirement and evaluation criteria before competitors even know the opportunity exists. In DataScene Tenders, the Upcoming opportunities page collects these signals, with AI-extracted expected timing (e.g. "expected August 2026") and the notice type classified for you — so you can reach out to the right buyer at the right moment.
Common pitfalls — and how to avoid them
Answering the way you'd describe the work, not the way the rubric reads
Evaluators score against a rubric. If it awards points for "evidence of relevant past projects" and you write "we have extensive experience", you score zero. Mirror the rubric's language in your structure.
Missing the expression-of-interest deadline
Many tenders give you only days to register interest before the documents lock. Track EOI deadlines as carefully as the submission date.
Skipping the clarification window
Buyers usually take questions until a few days before submission. A sharp question that exposes ambiguity is free intelligence — and forces a clarification to every bidder, levelling the field.
Pricing without reading the model contract
Standard contracts carry liability caps, indemnities and payment terms that radically change your real margin. Read the schedule before you quote.
Ignoring the losing-bid debrief
You're entitled to a written debrief of your score per criterion against the winner's. Always request one — it's the best intel for the next bid to that buyer. A one-in-three win rate is healthy, so treat every loss as data.
Certifications that win points
Selection questionnaires increasingly award marks for recognised standards, and some are pre-conditions. Worth having ready:
- ✓ISO 9001 — quality management (the most-requested)
- ✓ISO 14001 — environmental management
- ✓ISO 45001 — health & safety management
- ✓SSiP / SMAS Worksafe — H&S scheme (construction-heavy sectors)
