Every UK public sector contract, searchable in one place.

How big is the UK public sector contract market?

The UK public sector spends approximately £290 billion per year on goods, services, and works contracted from external suppliers. This is about 13% of total government spending and covers everything from paperclips for a village council to multi-billion-pound defence programmes.

Of that £290bn, roughly £39 billion flows to SMEs — small and medium enterprises with under 250 employees. Central government has a 33% SME spend target, and departments publish quarterly progress reports against it.

Who buys and who sells

The buyer landscape covers eight broad sectors:

• NHS — approximately 40% of UK public spend. Trusts, Integrated Care Boards, NHS Supply Chain, NHS Shared Business Services. NHS tenders.
• Local government — 400+ councils buying everything from highways to social care. Local government tenders.
• Education — universities, schools, colleges, apprenticeship providers. Education tenders.
• Central government — Cabinet Office, MoD, DWP, HMRC, Home Office, DfE, DESNZ, and every other ministerial department. Often via Crown Commercial Service.
• Housing — housing associations and local authority housing departments. Biggest category: repairs and maintenance.
• Police, fire, emergency services — 43 police forces, 49 fire authorities, ambulance trusts. Emergency services tenders.
• Defence — MoD and its agencies (DE&S, DSTL, Submarine Delivery Agency). Distinct procurement rules.
• Transport — Highways England, Transport for London, Network Rail, local transport authorities.

Procurement regulations after the Procurement Act 2023

The Procurement Act 2023 came into force on 24 February 2025, replacing the Public Contracts Regulations 2015. It's the biggest reform of UK public procurement in a decade. Key changes for suppliers:

• Most Advantageous Tender (MAT) replaces MEAT as the evaluation standard — more flexibility on weighting.
• Single digital platform for central government notices (being rolled out).
• Below-threshold rules — defined but simplified requirements for contracts below statutory thresholds.
• Supplier debarment list — a new Central Digital Platform records excluded suppliers.
• Social value requirements strengthened; 10% minimum weighting is now the norm.
• Payment performance reporting is stricter.

Finding the right public sector contracts for your business

Three signals determine whether a contract is worth pursuing:

Sector fit. Do you genuinely deliver what the buyer is asking for? Adjacent experience doesn't convert well.

Geography. Some services (social care, cleaning, maintenance) are location-bound; others (software, consultancy) aren't. Filter accordingly.

Capacity. A £50M outsourcing contract needs a different supplier than a £50k refresh. Match contract size to your delivery capacity.

WinAContract's search filters let you narrow by all three simultaneously, plus deadline and buyer type.

The fastest workflow for public sector suppliers

1. Set a keyword alert covering your core sector terms. Daily email delivery is standard.

2. Review alerts for 15 minutes each morning. Filter out obvious non-fits; flag 1-3 for deeper review.

3. Qualify within 48 hours. Use a Bid/No Bid framework — scoring the opportunity on 6-8 factors — rather than a gut decision.

4. Register on the buyer portal at qualification stage, not submission stage. Portals sometimes require ID verification or document uploads that take days.

5. Draft responses to a template. Every public-sector bid asks the same 15-20 question types — methodology, team, experience, social value, risk. Templates cut response time 50%+.

6. Use the bid/no-bid data. If you're winning 1 in 10 bids, either your qualification is wrong or your response quality is. Both are fixable with data.

Public sector contract values and payment terms

UK public sector contracts pay on time. Central government has a contractual 30-day payment terms policy, and prompt payment performance is now publicly reported under the Procurement Act 2023.

Contract sizes range from single-digit thousands (councils publishing everything above £12k) to multi-billion-pound infrastructure programmes. The sweet spot for most SMEs is £100k-£2M contracts — large enough to matter, small enough to win against reasonable competition.
