Why you are seeing this: it applies whatever you answered.

The single statutory place UK contracting authorities publish procurement notices under the Procurement Act 2023, and since 24 February 2025 the place suppliers register their organisation once and reuse that supplier information across bids. Registration produces the core supplier record other routes increasingly expect you to already hold.

How to engage with it

1. Register your organisation and a first administrator, then add further users -- you only need to do this once, not per bid.
2. Have ready: registered name and address, Companies House or charity number, VAT number if applicable, recent accounts, trade assurances or qualifications, whether you are an SME or VCSE, and your position on the mandatory and discretionary exclusion grounds in schedules 6 and 7 of the Act.
3. Set up notice searches and alerts against the categories you actually serve, rather than reading the whole feed.
4. Keep the supplier information current: it is reused at bid time, and a stale record slows every subsequent submission.

What it will not do: It is not a marketplace and no one browses it looking for you. Registering makes you able to bid; it does not make you visible to buyers.

Why you are seeing this: it applies whatever you answered.

From 1 April 2026 a supplier awarded a below-threshold contract must be registered on the central digital platform and hold a unique identifier, which the contracting authority includes in the contract details notice it publishes.

How to engage with it

1. If you win low-value public work -- the kind that never went near a formal tender -- register anyway and obtain your unique identifier before award.
2. Give the identifier to the contracting authority when they ask for it at award; they cannot publish the notice correctly without it.
3. Treat it as a prerequisite rather than paperwork: an unregistered supplier can hold up its own award.

What it will not do: It is not a separate registration from Find a Tender -- it is the identifier that registration gives you.

Run by Cabinet Office · For when something has already gone wrong.

Why you are seeing this: it applies whatever you answered.

The service that investigates a supplier's complaint about a specific public procurement or the management of a public contract, including late payment of invoices. Suppliers can raise a concern anonymously. It has recovered substantial sums in late-payment cases.

How to engage with it

1. Raise the issue with the contracting authority first where you can; the service reviews how the authority handled it.
2. Email publicprocurementreview@cabinetoffice.gov.uk with the specific procurement or contract, what happened and when. The issue must have occurred within the last two years.
3. Ask for anonymity if you fear commercial consequences -- it is offered, and it exists precisely because suppliers fear complaining.
4. Use it for unpaid undisputed invoices as well as process complaints; late payment is explicitly in scope.

What it will not do: It is not a legal remedy and does not overturn an award. Statutory challenges have their own short deadlines and require legal advice, quickly.

Run by NHS England · This sector runs its own portal alongside the national ones.

Why you are seeing this: it applies whatever you answered.

The single Health Family system through which the large majority of NHS organisations run procurement planning, tendering, contract and supplier management. For suppliers it is the direct route to most NHS opportunities.

How to engage with it

1. Register on the supplier portal -- registration is free and has no prerequisites.
2. Set business alerts for your categories, and check your existing NHS contracts through the same account.
3. Complete the Evergreen sustainable supplier assessment: NHS buyers use it to see how you align with the NHS net zero and sustainability requirements.

What it will not do: It is one system, not every NHS buyer. Some trusts and collaborative procurement hubs still run their own portals.

Run by BlueLight Commercial (national policing) · This sector runs its own portal alongside the national ones.

Why you are seeing this: it applies whatever you answered.

The national commercial body for policing, holding responsibility for commercial, procurement and contract management activity for police ICT, including re-procuring existing national agreements.

How to engage with it

1. Register free on its supplier portal to see opportunities and receive alerts.
2. Understand which national agreements cover your ICT category and when they are next re-procured -- much of police technology buying is consolidated nationally rather than force by force.
3. Note the below-threshold rule from 1 April 2026: you will need a central digital platform unique identifier at award.

What it will not do: It does not buy for every force in every category; individual forces still run their own procurements.

Run by Ministry of Defence · This sector runs its own portal alongside the national ones.

Why you are seeing this: it applies whatever you answered.

The MOD's own platform for defence contract opportunities and tendering. Opportunities can be viewed without an account, but bidding requires supplier registration on the portal.

How to engage with it

1. Register as a supplier and set category-based notifications; browsing without an account lets you research, not bid.
2. Get your security and assurance position sorted before an opportunity closes: Cyber Essentials certification is expected for handling MOD information, and roles may require BPSS, SC or DV clearance depending on the contract.
3. Read the MOD's supplying-to-defence guidance for the contracting conditions that differ from civil government.

What it will not do: It is not a route into classified programmes on its own, and registration does not confer any clearance.

Run by Department of Finance, Northern Ireland · This sector runs its own portal alongside the national ones.

Why you are seeing this: it applies whatever you answered.

Northern Ireland's public sector tendering portal, used by central and local government bodies for procurements above the relevant thresholds. Northern Ireland procurement policy is set by the Department of Finance.

How to engage with it

1. Register on the portal and set alerts for your categories.
2. Read the Department of Finance procurement guidance for the NI-specific policy and Centre of Procurement Expertise structure before bidding.
3. Register separately on Find a Tender as well where UK-wide notices apply.

What it will not do: It is not a route to Great Britain opportunities, and NI policy differs from the rest of the UK.

Run by Scottish Government · This sector runs its own portal alongside the national ones.

Why you are seeing this: it applies whatever you answered.

Scotland's national advertising portal, used by the Scottish Government, councils, NHS Scotland, universities, police and other devolved bodies. It covers contracts of all values, including low-value Quick Quote opportunities that never appear elsewhere.

How to engage with it

1. Register and record an interest in a notice to reach the tender documents -- viewing the notice is not the same as accessing the procurement.
2. Set up category alerts, and include Quick Quote categories: for smaller suppliers this is often where the reachable work is.
3. Treat this as a separate registration from Find a Tender, not a duplicate of it.

What it will not do: It does not cover reserved UK-wide procurement, and registering here does not register you anywhere else.

Why you are seeing this: it applies whatever you answered.

Wales's public procurement portal, connecting suppliers with Welsh Government, local authorities, NHS Wales, universities and housing associations.

How to engage with it

1. Register and set alerts against your categories and the areas of Wales you can serve.
2. Check the Welsh Government's own framework and delivery arrangements for your category before assuming a route is open.
3. Register separately on Find a Tender as well: the two are not linked.

What it will not do: It is a Welsh public sector route only, and does not carry opportunities from the rest of the UK.

Run by Government Commercial Agency (GCA) / Cabinet Office · A managed relationship, not a way in.

Why you are seeing this: it applies whatever you answered.

A network of senior representatives who act as the focal point between government and particular groups of suppliers -- strategic suppliers, sectors, SMEs, VCSEs and mutuals -- so that government can behave as a single customer rather than as dozens of unconnected buyers.

How to engage with it

1. Establish first whether you are actually in scope: this is a route for strategic suppliers and recognised sector groups, not a general contact point for a supplier seeking work.
2. Approach through the published programme contact -- markets-sourcing-suppliers@gca.gov.uk for questions about the Crown Representative programme -- rather than approaching a representative cold.
3. Come with a cross-government issue -- inconsistent treatment across departments, a sector-wide barrier -- not a single bid you want to influence.

What it will not do: It is not an escalation route for a specific procurement, and it will not intervene in a live competition. Use the Public Procurement Review Service for that.

Run by Contracting authorities, via Find a Tender · Opportunities are published here; nothing finds you.

Why you are seeing this: it applies whatever you answered.

The Procurement Act 2023 stage before a tender exists. An authority may publish a preliminary market engagement notice inviting suppliers to help it understand the market, and must run that engagement without giving any supplier an unfair advantage or distorting the competition that follows.

How to engage with it

1. Watch for preliminary market engagement notices in your categories on Find a Tender -- this is the earliest published point at which a requirement is visible.
2. Respond substantively about what is deliverable, what it costs and what the constraints are. Shaping realistic requirements is legitimate; angling for an advantage is not, and the authority is obliged to prevent it.
3. Expect to compete on the same terms as everyone else afterwards. Participating does not disqualify you, and it does not privilege you either.

What it will not do: It is not a sales meeting or a route to a sole-source award, and the authority must not let it become one.

Run by Innovate UK, UKRI · Funded development, competed openly, for problems with no existing solution.

Why you are seeing this: it applies whatever you answered.

Fully funded R&D contracts, run as open competitions, where a public body sets out a challenge that existing market solutions cannot meet and contracts organisations to develop something new. Suppliers retain the intellectual property generated, with defined rights of use retained by the contracting authority.

How to engage with it

1. Watch the Innovation Funding Service for open competitions and read the challenge statement carefully -- you are being contracted to solve a stated problem, not to sell a product.
2. Apply at phase one for feasibility; later phases fund development and are usually open only to phase-one participants.
3. Confirm the IP and rights-of-use position for the specific competition before committing: the general position is favourable, but the terms are per competition.

What it will not do: It is not a grant and not a procurement of a finished solution; it is an R&D contract and it does not guarantee later adoption.

Why you are seeing this: it applies whatever you answered.

The MOD's innovation front door: funded competitions for novel defence and security capability, aimed at getting ideas from organisations that would not usually win a defence prime contract.

How to engage with it

1. Read the open themed competitions and the enduring open call, and match your proposal to a stated defence problem rather than describing your product.
2. Enter at the phase that fits your evidence -- early phases fund proof of concept, not deployment.
3. Treat it as a route to a first funded relationship with defence, not as a substitute for the Defence Sourcing Portal once you are selling at scale.

What it will not do: It does not procure operational capability at volume, and a DASA award is not a production contract.

Why you are seeing this: it applies whatever you answered.

The agreement for bespoke digital work and digital specialists. A buyer publishes a brief describing the outcome or the capability it needs, appointed suppliers respond, and the buyer selects. DOS 7 is the current iteration.

How to engage with it

1. Apply when the iteration's application window is advertised; between windows you cannot respond to briefs.
2. Once appointed, monitor published briefs in your categories -- response windows are short, often two weeks or less.
3. Answer the brief's stated evidence questions specifically. Responses are scored on the evidence given, not on general capability statements.

What it will not do: It is not a catalogue -- nothing sells itself here. If you do not respond to briefs, appointment produces nothing.

The catalogue agreement for cloud services. Suppliers publish defined services at fixed or capped prices and public buyers search and buy from the listing without running a full competition. G-Cloud 15 is the current iteration.

How to engage with it

1. Wait for the next iteration's application window to be advertised on Find a Tender, then apply -- G-Cloud is re-competed periodically rather than open continuously.
2. Write each service entry as a discrete, priced, buyable thing: the catalogue is searched by buyers, so the listing is your shop window and vague entries do not get found.
3. Publish and maintain your service definition, pricing and terms documents on the Digital Marketplace once appointed.

What it will not do: It is not for bespoke build or people-based delivery -- that is Digital Outcomes and Specialists. Listing a service is not a sale.

The dedicated central space for smaller businesses selling to government: centralised guidance on bidding, and links to individual departments' published SME action plans, which state what each department is trying to buy from smaller suppliers and how.

How to engage with it

1. Read the SME action plan of the specific department you are targeting -- it names that department's own barriers, priorities and contacts, and most suppliers never look at it.
2. Use the central bidding guidance to prepare the standard evidence once, rather than assembling it under deadline for each bid.

What it will not do: It is guidance and signposting; no opportunities are advertised here.

Why you are seeing this: it applies whatever you answered.

The Procurement Act 2023 route that replaces dynamic purchasing systems: a list of qualified suppliers eligible for future competitions, which must stay open for new suppliers to join at any time. Unlike a closed framework, you are not locked out until the next re-competition.

How to engage with it

1. Find the dynamic market covering your category and apply -- applications are accepted at any time, not only at a fixed opening window.
2. Pass the published conditions for membership; there are no joining fees for the central dynamic markets.
3. Once admitted, expect to compete for individual requirements within the market -- membership is eligibility, not an allocation of work.

What it will not do: Membership does not guarantee any spend, and it does not exempt you from competing for each requirement.

Why you are seeing this: it applies whatever you answered.

The central commercial organisation's supplier-facing entry point, covering how to find opportunities and how its commercial agreements work. GCA was formed on 1 April 2026 from Crown Commercial Service and Cabinet Office central commercial teams; existing agreements, supplier listings and call-off contracts carried over unchanged.

How to engage with it

1. Identify which commercial agreement covers what you sell before chasing individual opportunities -- most central-government buying runs through an agreement rather than a standalone tender.
2. Check when the agreement you need is next re-competed, and prepare for that competition window rather than waiting for it to be advertised.
3. Follow the agreement's own supplier guidance for onboarding, catalogue entry and call-off rules once appointed.

What it will not do: GCA does not buy on a department's behalf as a favour to a supplier, and being on an agreement is not a sale.

Why you are seeing this: it applies whatever you answered.

Publicly owned buying organisations established by local authorities, running frameworks used by councils, schools, housing providers, emergency services and, in ESPO's case, central government and NHS bodies.

How to engage with it

1. Check each organisation's framework list for the category you sell, and apply when that framework is re-competed.
2. Register for their supplier opportunity alerts -- their framework competitions are advertised on the national notice services but their own alerts are more specific.
3. Expect catalogue-style terms and pricing schedules rather than bespoke contracting.

What it will not do: Neither is a route into a specific council's spend; individual authorities decide whether to call off.

NHS England's supplier-facing guidance on how NHS commercial activity is organised -- the central commercial function, the routes to market and what the NHS expects of suppliers.

How to engage with it

1. Use it to work out which part of the NHS actually buys what you sell before registering anywhere: national commercial function, a regional collaborative hub, or an individual trust.
2. Check the published expectations on sustainability, social value and data before you bid, not after.

The digital centre of government, formed by merging GDS, the Central Digital and Data Office, the Geospatial Commission and the Incubator for AI. It sets the service standards, the Technology Code of Practice and the spend controls that departments must satisfy for digital and technology investment.

How to engage with it

1. Read the service standard and Technology Code of Practice before you bid: a proposal that cannot pass an assessment is a proposal the department cannot buy.
2. Understand that digital spend above thresholds needs central approval, which is why buyers ask about standards compliance and reuse of existing components.
3. Frame proposals in terms of user needs, open standards and avoiding lock-in, because that is the test being applied to the department.

What it will not do: GDS does not buy on behalf of departments and is not a sales contact.

How to engage with it

1. Search it as a supplier first, as a buyer would: see how competitors describe and price comparable services before writing your own entries.
2. Keep listings, pricing documents and service definitions accurate -- the listing is the thing buyers compare.

How to engage with it

1. Read it to understand what a contracting authority is actually obliged to do, before deciding whether you have a complaint worth making.
2. Understand the debarment regime from the supplier side: exclusion grounds you must self-declare at registration are the same grounds assessed here.

How to engage with it

1. Search it for live legacy competitions and for award history when researching a buyer's past spend and incumbents.
2. Do not rely on it as your opportunity feed -- its share of live opportunity shrinks as legacy procurements complete.

What it will not do: It is not where new opportunities appear. Treat it as an archive and a research source, not a pipeline.
