Public affairs roadmap: best practice, step by step

Most public affairs wins are settled before the meeting that seems to settle them. The minister’s office already knows who you are, the department has your numbers, and the backbencher who raises it in the Chamber has been round your site. There are no shortcuts to that. It comes from building relationships before you need them, and keeping them up when you don’t.

This roadmap sets out how to do it, in order: an objective you can be held to, a map of who matters, an ask that fits the government’s priorities, a plan built around the parliamentary and fiscal calendar, and a report the board can trust. It’s written for in-house teams and agencies working at Westminster and across the devolved nations.

The short version

• Set an objective you can be held to: a decision, who makes it, and by when.
• Map who decides and who they listen to: ministers and their spads, officials, the Treasury and No 10, both Houses, the devolved governments and your allies.
• Build relationships before you need them, across the parties, and write down what you learn so it stays with the team.
• Make one ask, in the government’s terms, with local evidence.
• Work to the calendar: the session, sitting weeks and recesses, the Budget and the Spending Review, conference season and elections.
• Use the channels Parliament and Whitehall already have: consultations, select committees, bill committees and written questions.
• Plan for the long-running issues, and prepare for the sudden ones before they arrive.
• Stay within the lobbying, donations and transparency rules, and assume anything you send could be published.
• Report what the team did and what changed, and keep the two apart.

Set an objective you can be held to

“Raise our profile in Westminster” and “improve relationships with government” fail the same test: nobody can say when they’ve been met. A useful objective names the decision, who makes it and when, and is honest about the government’s appetite for it.

Template: “By [date], we want [decision-maker] to [decision], so that [result for our organisation].”

The example used throughout is Southcourt Foods, a food manufacturer with 450 staff, most of them at two plants in North Yorkshire and County Durham. The company, the scheme and the figures are fictional.

Example: “By the 2027 Budget, we want HM Treasury and DESNZ to fund a grants scheme for energy-efficiency upgrades at manufacturers with 200 to 500 staff, so that we can upgrade both plants.”

You can’t make a minister decide. You can make sure the people around the decision have heard your case from the right messengers, at the right time, with evidence they can use. Set objectives for both: the outcome, and the work that gives it the best chance.

Agree them with whoever owns the business problem, such as operations, finance or the chief executive. Otherwise the team drifts towards whatever is easiest to get a meeting about.

Map who decides

Most decisions run through more people than the minister whose name ends up on them.

• The department: the policy team designs the scheme and writes the advice, a bill team carries any legislation, and the private office runs the minister’s diary and papers. An official will sit in on any meeting with the minister. Civil servants are impartial under the Civil Service Code, so give them evidence and analysis, not politics.
• Ministers and spads: the Secretary of State, the minister who holds your brief, and the special advisers who handle the politics, the media and the grid. A spad who understands your case can get it in front of the Secretary of State faster than any letter.
• The Treasury and No 10: anything that costs money has to get past the Treasury, and No 10 and the Cabinet Office decide what is announced and when. You rarely lobby them directly. You give the department what it needs to win the argument with them.
• The Commons: backbenchers in every party, especially those with your site in their constituency or a record on your issue; the select committee that shadows the department, its chair and its clerks; and the APPG on your subject, if it’s active.
• The Lords: no party has a majority, crossbenchers sit with none, and much of a bill’s line-by-line revision happens there. On a bill that matters to you, the peers who lead on it can matter as much as the minister.
• The opposition: shadow ministers and the other parties’ spokespeople. Governments and ministers change, and a relationship built in opposition is one you don’t have to start from scratch.
• Edinburgh, Cardiff and Belfast: for health, education, housing, planning and much else, the decision is devolved, and the line falls differently in each nation. Each has its own parliament, committees, budget and habits, and a Westminster relationship doesn’t carry across. The Scottish and Welsh governments formed in May 2026 are both minority governments, so their budgets and bills need other parties’ votes. In parts of England, combined authority mayors hold powers and budgets of their own.
• Regulators: their decisions and guidance can matter more day to day than the policy behind them.
• Allies and opponents: trade associations, unions, charities, think tanks and other businesses, whose positions strengthen or weaken yours.

Keep the map to one page. For each person, note their influence on the decision, where they stand now, what they care about and your next step. Review it monthly, and after every reshuffle or election. The GovConnex directory covers every MP and peer, MSP, Member of the Senedd and MLA, with their roles and committees.

Follow what they say. Read your targets in Hansard, at committee, in their written questions and on social media, so you know their priorities before you pitch to them. A new MP’s maiden speech is a good guide to what they’ll fight for in their constituency. A political monitoring service can alert you when they raise your issue.

Build relationships before you need them

Relationships with MPs, peers, spads, officials and regulators come from steady, useful contact, not one-off asks.

Start early. If a spad has met you, read something useful from you or been round your site, your call is more likely to be returned when an issue lands.

Start with the backbenches. Sound out backbench MPs and peers before you escalate. They’ll tell you how an ask will play in their party, and they can raise it in ways you can’t.

Meet the officials and spads. If the minister’s diary is closed, the officials who lead on your issue and the spad who covers it shape what reaches the minister, and how.

Be useful as well as persuasive. Data they can’t get elsewhere, early warning of a problem on the ground, an invitation to see the operation: contact that brings something keeps the door open for contact that asks for something.

Go where they are. Party conference season each autumn, with its fringe events and receptions; APPG meetings; think tank launches; sector events in Westminster. On Fridays when the House isn’t sitting, and in recess, MPs are mostly in their constituencies, which makes it the time for a site visit.

Write it down. When someone leaves, what they knew about a minister’s office tends to leave with them. Log meetings, commitments and positions in one shared place, such as a public affairs CRM: why a sales CRM falls short explains what to look for.

A workable rhythm for a small team:

Make one clear ask

Write the ask in one sentence before you write anything else, and know how it sits with the politics of the moment: how the issue is being covered, where the public is on it and, more to the point, where No 10 thinks the public is. An insights tool shows how the debate on your issue has moved, and who raises it most.

Template: “We’re asking [person] to [specific action] by [date], because [what it does for their priorities]. [One figure that matters to them.]”

Example: “We’re asking the Energy Secretary to back a grants scheme for energy-efficiency upgrades at manufacturers with 200 to 500 staff in the 2027 Budget, because it keeps manufacturing jobs in the North. Our two plants employ 380 people.”

Keep it to a page. Open with the request and put the detail in a briefing note. A letter with three asks tends to get none of them answered.

Say the same thing to everyone. A message that shifts with the audience gets noticed, inside government and out.

Make the evidence local. Jobs, suppliers and apprentices in an MP’s own constituency carry more weight than national totals. Add what the change would cost or save, and who pays.

Offer case studies. Show what a policy means for a business, a profession or a community, not just what it means in aggregate.

If it costs money, help the department make the case to the Treasury. Departments spend within the settlements agreed at the Spending Review, so a new scheme either finds room in its department’s budget or wins new money at a Budget. Give officials figures they can check, and say where they came from. The Treasury’s guidance on Budget representations asks for the same: the rationale, costs, benefits and deliverability of a proposal.

Make the meeting count. Go in with one thing you want them to remember, leave a one-page note, and follow up within a day.

Work to the calendar

Timing decides more proposals than argument does. Have the paper written before the window opens: a reshuffle, a fiscal event or a crisis can open one with little warning, and ministers reach for whatever is ready.

The session. The King’s Speech sets out the government’s bills for the session, and those bills are designed long before it. If you want something in legislation, the department needs to hear it while the bill is being drafted, not once it has been introduced.

The week. The Commons usually sits Monday to Thursday, and on some Fridays for private members’ bills. Avoid a department’s oral questions day, PMQs at noon on Wednesday, the run-up to a fiscal event and any political crisis. Sitting days are for Westminster; recess and non-sitting Fridays are for constituencies. Recess dates, including the conference recess in September and October, are on the Parliament website once announced: plan around them.

The money. Most Budget decisions are made in the months before the Budget, and departments’ budgets are set at Spending Reviews, now every two years, with the next due in 2027. An ask that needs new money should be with the department well before decisions are made, in time for its case to the Treasury. The Treasury usually invites representations before each Budget: for the Budget on 28 October 2026, they closed on 9 September.

Elections. Once an election is called, the pre-election period begins. Ministers keep governing, but decisions a new government might take differently wait for the result, and so do big or contentious contracts and sensitive appointments. The Cabinet Office issues guidance before general, devolved and local elections alike, and the devolved governments and councils follow their own. The next general election is due by August 2029. Closer to hand, Northern Ireland’s Assembly and councils are due to vote on 6 May 2027: if you need a decision from the Executive, aim to have it made before the pre-election period starts, or plan to take it to the next one.

Before an election, brief candidates as well as sitting MPs. They’re easier to reach, and the ones who don’t win often turn up later in an office you need. If you offer a site visit during the campaign, offer it to every party on the same terms.

Use the channels Parliament and Whitehall already have

Consultations. Departments consult on most significant changes. Respond to the ones on your issue with data, and talk to the policy team before a consultation closes, not after.

Written questions. Any MP or peer can table one, and the answer is published. A sympathetic member asking the right question gets the government’s position on the record.

Debates. MPs can apply for Westminster Hall and adjournment debates, which put an issue to a minister for a reply. Early day motions show who is sympathetic, but rarely move anything on their own.

Select committees. Each department is shadowed by a Commons select committee, and the government usually replies to its reports within two months. When an inquiry touches your issue, send written evidence, offer to give oral evidence and read what others submit. Once the committee has your evidence it’s the committee’s to publish: ask before you publish it yourself, as your own copy may not be covered by parliamentary privilege.

Bills. When a government bill reaches public bill committee in the Commons, anyone can send written evidence, including suggested amendments, and the minister in charge sees every submission. The bill then goes to the Lords, where detailed amendments often get their best hearing.

Scrutiny of spending. The Public Accounts Committee builds its inquiries on the National Audit Office’s value-for-money reports. Its transcripts, and the letters departments send committees afterwards, show what a department is really saying about your issue.

Letters. Correspondence to a minister is logged by the private office, and many replies are drafted by officials. Address a Secretary of State as “The Rt Hon [name] MP, Secretary of State for [department]”, and copy the spad if they need to see it.

Manage long-running issues

The issues that matter most rarely resolve in one Budget. They need a plan, resources and someone who owns them.

Know the landscape. Follow the legislation, regulation, inquiries and consultations that touch you, and what’s driving them: public opinion, other interests, the economy, the public finances. Know the government’s constraints too: its manifesto, its fiscal rules and what it has already ruled out. Working within them is usually what makes a proposal realistic. Scan the horizon each quarter for what is likely to matter in the next six to eighteen months: our guide to political intelligence explains how.

Set a strategy for each issue. The goal, the mix of tactics (direct engagement, consultation responses, committee evidence, coalitions, media and supporters), and the people, budget and time to carry it through, on one page.

Build a coalition. Find the trade associations, competitors and partners who want the same thing. A joint ask is easier for government to say yes to: Southcourt’s case is stronger made alongside other food manufacturers and their trade association.

Be ready for good news. If a Budget or an announcement goes your way, back it publicly on the day, as a third party. Ministers remember who stood up for them when it counted.

Handle the sudden ones

Some issues arrive without warning: a hearing, a story, a regulator’s letter.

Move fast. Name a small response team in advance, so it can meet within the hour, and assess the legal, reputational, financial and regulatory exposure.

Agree the goal, then act. Correcting the record, limiting the damage and settling a regulatory concern call for different responses. Give each action an owner, agree one line for staff, government and the public, and change course when the facts do.

Don’t go over the department’s head lightly. Taking it to No 10, or to a First Minister’s office, is a last resort, and it’s remembered.

Debrief afterwards. What happened, what worked and what you’d change, written down while it’s fresh.

If your organisation is named in a select committee evidence session, the first two days might look like this:

Stay within the rules

If you lobby for clients, register. Consultant lobbyists paid to communicate with a minister or permanent secretary on a client’s behalf must be on the Register of Consultant Lobbyists before they start, and declare their clients every quarter. Lobbying MPs or spads isn’t covered, unless the MP is also a minister. Work done at the direction of a foreign power needs registering separately, under the Foreign Influence Registration Scheme.

In-house teams don’t register at Westminster, though some join the voluntary registers kept by the CIPR and the PRCA. Departments publish ministers’ meetings with outside organisations every quarter, so expect yours to be on the record. Scotland is different: under the Lobbying (Scotland) Act 2016, an organisation whose paid staff lobby MSPs, Scottish ministers, special advisers or the Permanent Secretary in person or by video must register and report it.

Check before you hire from government. Under the Ministerial Code, former ministers are, as a general rule, barred from lobbying government for two years after leaving office. Former permanent secretaries, the most senior civil servants and spads of equal standing face the same two-year ban under the Business Appointment Rules, and others can have a lobbying ban attached to a new job for up to two years.

Keep donations separate. Sponsoring a party’s conference event or publication counts as a donation, and so does what you pay for a table at a fundraising dinner above the value of the dinner. Parties can accept a donation over £500 only from a permissible donor, such as a company registered in the UK that carries on business here, and report larger donations to the Electoral Commission, which publishes them. The Representation of the People Bill, now in the Lords, would change the rules on company donations. Agree a policy with legal and finance, and keep donation decisions apart from your engagement.

Write as if it will be published. Information held by departments, ministers’ correspondence included, can be requested under the Freedom of Information Act 2000 (in Scotland, the Freedom of Information (Scotland) Act 2002), and select committees usually publish the evidence they receive.

Measure and report

Evaluation tells you whether the work is landing, and gives the board a reason to keep funding it. Measure at three levels:

Then put a value on each outcome: costs avoided, revenue protected, risk reduced.

Report activity and outcomes separately. A run of meetings followed by a policy change doesn’t prove one caused the other, and a board trusts a team that says so. Say what the team contributed, what else changed and what comes next.

Review on a rhythm: the stakeholder map and issue plans monthly, a report to leadership each quarter, and the objectives once a year, or sooner after an election or a reshuffle.

A 12-month roadmap, worked through

Here’s how it fits together for Southcourt Foods (fictional), from October 2026 to the 2027 Budget and after.

Common questions

What’s the difference between public affairs, government relations and lobbying? Public affairs is the whole discipline: working with government, Parliament and the wider debate around them to shape the decisions that affect an organisation, through relationships, evidence, media and campaigns. Government relations is the part done directly with ministers, officials and parliamentarians. Lobbying is seeking to influence a particular decision. At Westminster, only consultant lobbyists who communicate with ministers or permanent secretaries for clients have to register; in Scotland, in-house teams that lobby MSPs and ministers must register too.

Should we use a public affairs agency? An agency adds relationships, know-how and capacity, especially around a change of government, a Budget or Spending Review ask, or an issue outside your team’s experience. It can’t replace your organisation’s own relationships and evidence. Check that it’s on the Register of Consultant Lobbyists if it will lobby ministers for you, which code of conduct it follows, how it handles conflicts between clients, and whether it works across the parties.

How long does public affairs take to pay off? Relationships take months to build, and a policy change often takes a Budget or Spending Review cycle, or longer. Set quarterly measures, such as people met, positions moved and consultation responses submitted, so leadership can see progress before the outcome.
