How to Sell to UK Government Under the Procurement Act

To sell to UK central government, pick one department or agency and follow its published plans on the Central Digital Platform. Check whether it buys your category through a Government Commercial Agency framework or dynamic market. Then reach the person who owns the budget while the requirement is still being shaped. That last step is where most suppliers turn up late.

The rules changed on 24 February 2025, when the Procurement Act 2023 started to govern how public bodies buy (GOV.UK guide to the Central Digital Platform). Big-spending departments now publish pipelines of their larger planned contracts, and they can run preliminary market engagement before any tender appears.

A supplier who reads those signals can be in the conversation months before tender day. Everyone else meets the requirement once it is already written.

How do you sell to UK central government at all?

In this guide, central government means ministerial departments such as the Cabinet Office and HM Treasury, plus the agencies and public bodies that sit under them. It covers services, software and supplies.

Councils, NHS trusts, police forces, defense and construction buy with different budgets and different people, so none of them are covered here.

There are five practical ways into that buyer group:

1. The Central Digital Platform, also called the enhanced Find a Tender service, where regulated procurement notices are published.
2. Frameworks run by the Government Commercial Agency (GCA). Older documents, including the 2025 SME action plans, still say Crown Commercial Service (CCS), so search for both names.
3. Dynamic purchasing systems and dynamic markets, which suppliers can join after they open.
4. Contracts a department runs itself. The Cabinet Office and HM Treasury, for example, keep the option to contract directly with SMEs outside CCS agreements when that gives the best value for money (their SME action plan).
5. Conversations with the budget owner during market engagement, which is what most of this article is about.

Before any of that, choose where to aim. When a founder tells me they want to sell to "the government", I ask which of their current clients looks most like one specific department, in size, in the problem it has and in who signed the deal. That department is your first cluster. The arithmetic behind choosing it is the same one I explain in my guide to choosing a market before any outreach.

Government is far too big to treat as one market. I would rather see a supplier work one department or agency cluster properly for a full year than touch many public bodies at once. See why in pick one offer and one audience for twelve months.

What changed for suppliers under the Procurement Act?

Two changes matter most if you want to be early. This is not legal advice.

Pipeline notices show the next 18 months

A contracting authority that expects its spending on relevant contracts to exceed £100 million next financial year must publish a pipeline notice within 56 days of that year's first day (Procurement Act 2023, section 93).

The notice covers every public contract estimated at more than £2 million that the authority plans to put out through a tender notice or a transparency notice. The reporting period runs for 18 months from the start of the financial year. The section does not apply to private utilities or to transferred Northern Ireland authorities.

The Cabinet Office guidance set 26 May 2025 as the deadline for the first pipeline notices. It also shows what can follow one: a preliminary market engagement notice, a planned procurement notice, a tender notice and a transparency notice (pipeline notice guidance).

Put plainly, every big department now tells the market which larger contracts it means to buy over the next year and a half. Few private buyers ever hand you that.

Preliminary market engagement is where requirements take shape

Preliminary market engagement happens before the tender or transparency notice. An authority can use it to develop its requirements, design the procedure, identify suppliers and build capacity among them (preliminary market engagement guidance).

An authority that runs this engagement must publish a notice before the tender notice, or explain why it did not. The guidance treats publishing as standard practice.

There is a hard limit. Engagement must keep competition fair and must not hand one supplier an edge, and a supplier whose involvement created an advantage that cannot be removed must be excluded from the procurement.

So the aim in these conversations is to inform the requirement with evidence. A supplier who tries to write the specification around its own product is putting itself at risk.

How do the Central Digital Platform and Find a Tender work?

The Central Digital Platform is where all regulated public procurement notices are published. There are 17 notices across procurement and contract management, including UK1 for pipeline, UK4 for tender and UK6 for contract award (GOV.UK platform guide).

Saved searches send you an email when a new notice matches the criteria you set. The data follows the Open Contracting Data Standard and can be reused with Open Government Licence 3.0, so you can pull it into your own tracking sheet.

What the platform cannot do is sell for you. A notice tells you a requirement exists. It reveals very little about who is pushing for it or why.

Set it up like this:

1. Create one saved search per target department or agency, using the buyer's name.
2. Add searches for the words that department uses for your category, such as "casework system" or "service desk". The product name on your website is rarely the term the buyer types.
3. Note the estimated value of each result. A contract over £2 million at a big-spending department is the kind that belongs in a pipeline notice, so a tender you never saw coming means you missed an earlier signal.
4. Rank alerts by notice type. A pipeline or market engagement notice is a reason to start a conversation. A tender notice is a reason to bid.
5. Review the alerts once a week and log each one against the department in your CRM, so you can see each buyer's history in one place.

What does a CCS or GCA framework actually give you?

GCA lists 4 ways to sell through it: frameworks, catalogues, dynamic purchasing systems (DPS) and dynamic markets (GCA's supplier guide).

Frameworks help public bodies buy goods and services from suppliers, and suppliers tender competitively for a place on one. A dynamic market accepts applications whenever you are ready, and a DPS stays open to applicants while the agreement runs. GCA says its routes open the door to 20,000 public sector buyers with more than £37 billion of yearly spend, which covers the whole public sector and not only central government.

The CCS SME action plan adds two details that matter for timing (CCS SME action plan). A DPS application is usually quicker and simpler than a framework application. Open frameworks may run for as long as 8 years and let new suppliers join or rejoin at different points, so missing the first window does not shut you out for the whole term.

The same plan gives the number that should cool expectations. In April 2025, roughly three in four CCS agreement suppliers were SMEs, but just under 11% of direct spend went to SMEs. A lot of suppliers hold a place and win a small share of the money.

A framework place makes you eligible to compete. Whether you get picked for a direct award or invited into a further competition depends on the department's team knowing who you are and trusting that you can deliver.

If you are aiming at contracts over £5 million, GCA lists a carbon reduction plan among the requirements, and it is worth writing before you need it.

Which departments are pushing SME spend now?

The government calls SMEs a national priority. Departments publish SME action plans, and they can voluntarily set indirect targets and report against them every year (departmental small business procurement targets). The CCS plan says public bodies must consider SMEs in each procurement under the Act.

The Cabinet Office and HM Treasury figures come from their joint SME action plan for 2025 to 2028; the other two come from the departmental targets table.

For scale, CCS reported in July 2024 that in 2023/24, £3.52 billion of central government spend, 16.7%, went directly to 1,525 SMEs. That was £370 million more than the year before. Total direct spend through its commercial agreements was £30.3 billion (GCA report on CCS 2023/24).

Read the targets as pressure on the buyer, not a promise of demand. A department with a 40% target needs more SME suppliers it can actually use, and that gives its commercial team a reason to hold supplier days and take meetings. Whether they buy from you still depends on the requirement.

Who decides inside a department before the tender?

Two groups matter, and they want different things.

The commercial team owns the process: the procedure, the notices, the evaluation and the value-for-money case. They care that the procurement is lawful and fair.

The budget holder owns the outcome. That is the director whose service is struggling, or the senior responsible owner of a program. They care whether the problem gets solved, and before a tender exists they are the ones deciding what the problem actually is.

Most suppliers write to commercial inboxes. The earlier conversation is with these four roles:

• Senior responsible owner, where a program has one: accountable for whether it delivers.
• Commercial lead or category lead: runs the procurement and decides the route.
• Director of digital or chief digital and information officer: owns technology choices and digital spend.
• Director or head of operations: owns the service the contract is meant to fix.

Before any campaign, I go through a client's past deals and find out who really signed each one, because it is often not the title the founder expected. Then I target that exact title, never a vague label that could mean anyone. Generic titles like assistant, associate or plain "manager" come off my list before a single message is sent.

A checklist for finding the names before procurement starts:

• The department's published organization charts and leadership pages, for directors by area
• Press releases and announcements that name who leads a program
• Contract award notices (UK6), for what was bought, from whom, and who the current supplier is
• Market engagement notices and supplier event agendas, for who presents the requirement
• LinkedIn searches for the department name plus the title, checked against the program in question
• Case studies published by previous suppliers that name the team they worked with

Expect each of these people to check you before they reply.

When should outbound reach government buyers?

The rule is simple. Outbound belongs in the period when the department is still shaping the requirement: after a pipeline notice shows intent and before a tender notice fixes the specification. Once the tender is live, the sales conversation is over and the bid takes its place.

Decision rules for contacting a department:

• Contact when your target buyer's pipeline lists a contract in your category, or a market engagement notice has gone out.
• Contact when an award notice shows an incumbent on work you could do better next time, and your note is about lessons for the next cycle.
• Contact when a department with an SME target announces a supplier day, and you can name the problem you would talk about.
• Do not contact once a tender notice is live, apart from through the formal channel.
• Do not contact if your aim is to get the specification written around your product. That is the unfair advantage the guidance warns about.
• Do not contact if you cannot name the program or the problem. When writing to a director, open with the buyer's problem; a line about "working with government" tells them nothing.

What to say matters as much as when. In a first message I sell the meeting and never the service. Here, the meeting is a short input session for their market engagement. A message like this works:

"Your casework replacement is in the pipeline. If useful for your market engagement, a 20-minute call can cover what goes wrong in similar migrations."

It asks for something small, and it gives the director something they can use whoever wins.

One message is never the plan. The way to run both channels together is in the follow-up sequence my team runs.

Then be patient. Government buyers move at the speed of their planning cycle, so do not judge the pipeline in week three.

What should a supplier do next week?

Start any campaign by reviewing the client's past and current clients, then find organizations that resemble them. Government is no different. Five steps, in this order:

1. Choose one department or agency cluster that looks like your best existing clients.
2. Confirm how they buy your category: a GCA framework, a DPS or dynamic market you can still join, or their own procurements.
3. Set up saved searches on the Central Digital Platform for those buyers and your category terms.
4. Build a short, countable list of the owners and commercial leads behind those buyers, using the checklist above, and check it the way I describe in auditing a lead list before sending.
5. Write one market engagement message for each program you found, with one piece of evidence in it.

Here is a made-up case that shows how the timing plays out. A software supplier sells case management systems to regulated organizations. It picks one department and two of the agencies under it. In late spring that department's pipeline notice lists a casework replacement estimated at £4 million, with a tender expected about a year later.

That week, the supplier finds the senior responsible owner through a program announcement, and the director of digital through the department's leadership page. It connects with both on LinkedIn and sends the short note above by email a few days later, then follows up twice over the next month.

Four months on, a market engagement notice appears. The supplier responds formally, and the director it already wrote to knows the name on the response. When the tender notice lands, the supplier stops selling and bids, from a position where its evidence was part of the market's input.

Nothing in that sequence breaks a rule or needs a big team. It needs one cluster, saved searches and a list of names worked steadily for a year. The IT side of that buying is in how to win work on G-Cloud as an IT services supplier.
