Why public sector marketing plays by different rules

A commercial campaign fails when nobody buys. A government campaign can hit every target it set and still be judged a failure, because the money behind it came from people who never chose to fund it and cannot ask for a refund. Add the fact that the organisation running the campaign also helps write the rules it is judged against, and you get a rulebook no commercial marketer ever has to read.

Three constraints do most of the work: public money, political neutrality, and duty of care. Substantiation rules, targeting limits and the pre-launch sign-off gate that later lessons cover all sit on top of these three. Get them wrong and the quality of the creative is beside the point.

Public money is not the same as a marketing budget

In UK central government, a department's permanent secretary is its accounting officer and is personally answerable to Parliament for four tests on any spending, campaigns included: regularity (the body had legal power to spend on this at all), propriety (the spend meets the standards expected of public money), value for money, and feasibility. A brand marketer defends a budget to a CFO who wants growth. A government marketer defends it to someone whose own name is on the answer.

The controls follow from that. Campaign spend above a centrally set threshold has to be cleared by the Cabinet Office through the UK Government Communication Service, so the department that wants the campaign is not the last word on whether it runs. Agencies and media buying come through tendered frameworks, which means you may not be able to hire the shop you rate most. Briefs, invoices, media plans and rejected concepts are all disclosable under freedom of information law, so "internal document" is a weaker category than it is in a commercial team.

In the US the constraint is appropriations law: money can only be used for the purpose Congress appropriated it for, and the Government Accountability Office issues legal decisions on whether an agency stayed inside that purpose. GAO works for Congress, not for the executive branch that ran the campaign. At the European Commission, communication spend is audited by the European Court of Auditors and picked over by the Parliament's budgetary control committee, and a campaign has to function across 24 official languages and 27 national media markets before anyone asks whether it worked.

Political neutrality: the constraint with no commercial equivalent

Government communication may explain and promote a policy that exists. It may not promote the party or the minister who made it. That single line is the hardest thing for marketers arriving from the commercial side to internalise, because the people who approve the work are politicians and the campaign that helps them most is usually the one that breaks the rule.

The UK propriety principles applied by GCS run roughly as follows: the communication has to be relevant to the responsibilities of government, objective and explanatory rather than party political, even-handed in how it treats people and places, and justifiable as a use of public money. Then there is the pre-election period of sensitivity, still widely called purdah, when departments pause campaign activity that could be read as influencing a vote. Marketers on a two-year plan have to design around a date they cannot move.

The US version sits in the appropriations acts, which carry long-standing prohibitions on spending appropriated funds on "publicity or propaganda" and on grassroots lobbying of Congress. GAO applies both to digital work: in 2015 it concluded that the Environmental Protection Agency's social media activity supporting its Waters of the United States rule had crossed those lines. Note what was at issue there. Not a TV buy. Organic social posts. Unpaid channels are inside the rulebook.

The Commission faces a related separation: institutional communication about the EU has to stay distinct from the campaigning of political groups, and the line is policed hardest in the run-up to European Parliament elections.

Duty of care: the audience did not opt in

Duty of care, in this module, is the obligation to anticipate harm to the people a message reaches, including the ones it was never aimed at, and to limit that harm before publication.

A brand chooses its audience and accepts that everyone else is waste. A public body cannot. Its audience is whoever the message reaches: people in debt, people recently bereaved, someone who will read a smoking warning while being treated for lung cancer, a child who sees a fraud awareness ad written for their grandparents. Nobody can unsubscribe from the state.

The duty is not a value statement. It has legal anchors. The public sector equality duty under the Equality Act 2010 requires UK public bodies to consider the effect of what they do, communications included, on people with protected characteristics. Accessibility is statutory: the UK's Public Sector Bodies (Websites and Mobile Applications) Accessibility Regulations 2018 and EU Directive 2016/2102 make accessible digital content a legal requirement for public bodies, where a commercial advertiser is often only exposed to a discrimination claim. And there is an implicit reachreachThe number of unique people exposed to your message in a given period. Unlike impressions, reach counts each person once, no matter how often they see it.View full definition → obligation: if an entitlement exists, the state has to make it findable by people who are not online at all.

How you adapt message, channel and data practice for at-risk audiences without gutting your reach is the next lesson. What matters here is that the duty applies by default, before anyone writes a brief.

The actors who enforce it

• A central communication authority, which sets professional standards, runs spend controls and can stop a campaign before launch. GCS plays this role inside UK government; DGDGData governance is the set of policies, roles, and processes that ensure data is accurate, secure, well-defined, and used responsibly across an organization.View full definition → Communication does something comparable inside the Commission. This is the actor a commercial marketer has no analogue for: a body outside your organisation that owns your professional standards.
• A state auditor. GAO can rule that spending was unlawful. The National Audit Office and the European Court of Auditors ask whether the money bought anything. Their sanction is a published finding, which in public life travels further than a fine.
• Advertising and consumer regulators, applying the same misleading-claims and fairness codes that bind commercial advertisers, with no discount for good intentions. A later lesson takes these on directly.
• Data protection authorities, which decide whether citizen data collected for one purpose can be used to target a message about another.
• The political layer: ministers, select committees, opposition researchers and journalists holding FOI rights. It has no commercial equivalent and it moves fastest. A campaign can be pulled within days of a hostile news cycle, long before any regulator opens a file.

CONSTRAINT             THE TEST APPLIED                    WHO CAN ACT ON IT
Public money           regularity, propriety, value        accounting officer,

                       explanatory, even-handed,           parliament, opposition, press
                       not party political
Duty of care           harm anticipated and limited        ad and consumer regulators,
                       before publication                  data protection authority, courts

Why this matters more in 2026

Two shifts are unsettling rules written for broadcast-era publicity. The first is synthetic creative. A brand using an AI-generated face in an ad has a disclosure problem. A public body doing the same has a propriety problem, because the state is showing citizens a person who does not exist and asking them to act on it. The second is paid creators. State money paying an individual to advocate a policy in their own voice sits very close to the publicity-or-propaganda line GAO has already applied to government social media, and closer still when the payment is not visible in the post.

Cross-border reach compounds both. A campaign placed on a global platform by a UK department or by the Commission lands in jurisdictions whose codes and privacy regimes were never part of the sign-off.

The working assumption for anyone marketing with public money: more than one actor is entitled to review your work, at least one of them reports to somebody other than your boss, and the constraint that stops your campaign is more often propriety or neutrality than a misleading claim.

Key takeaways

• Public money brings four tests no commercial budget faces: regularity, propriety, value for money and feasibility, with a named official answerable for them and an auditor free to publish its verdict.
• Political neutrality means government communication can promote a policy but never the party or minister behind it, and the restriction tightens in pre-election periods. Organic posts count, as GAO's 2015 finding on EPA social media activity showed.
• Duty of care is the obligation to anticipate and limit harm to everyone a message reaches, not only the intended target, and it has statutory anchors in equality and accessibility law.
• The enforcers are layered: a central communication authority such as GCS, a state auditor such as GAO, advertising and data regulators, and a political layer of committees, opposition and FOI-armed journalists that acts faster than any of them.
• The Commission adds scale to the same three constraints: 24 languages, 27 markets, and audit by the European Court of Auditors.
