UK lobbying rules: who must register, and what is about to change

Who has to join the UK lobbying register today, why most businesses and charities do not, and what the Ethics and Integrity Commission's proposals would change for in-house teams.

Downing Street SW1 street sign above black railings, tinted green, with the headline UK lobbying rules: who must register.

UK lobbying rules are narrower than most people expect. If you work in-house for a company, a trade body or a charity and you meet ministers about your own organisation's interests, the law does not currently require you to register as a lobbyist. That could change. In July 2026 the Ethics and Integrity Commission recommended replacing the current register with one that covers almost everyone who lobbies government, and the government's response is still awaited. This guide sets out who must register today, what the proposals would mean for your organisation, and what is worth doing now.

In force or proposed? The registration rules for consultant lobbyists are law today and have been since 2015. The Ethics and Integrity Commission's changes are recommendations only: none of them is law yet.

This is a practical guide, not legal advice. If you think you may be in scope, the Office of the Registrar of Consultant Lobbyists publishes detailed guidance and will answer questions directly.

What counts as lobbying under UK law?

The statutory rules sit in Part 1 of the Transparency of Lobbying, Non-party Campaigning and Trade Union Administration Act 2014, usually called the Lobbying Act. It defines lobbying as an oral or written communication made personally to a minister or a permanent secretary (or an equivalent senior official) about:

making or changing legislation, primary or secondary;
developing or changing any other government policy;
government contracts, grants, other financial assistance, licences or authorisations;
any other government function.

That definition is broad on subject matter and very narrow on audience. A meeting with a special adviser, a director general or a director in a department falls outside it, even though those officials often shape policy more directly than the minister does.

Who has to register as a lobbyist in the UK?

Only consultant lobbyists. This is a legal requirement in force now: the register opened on 25 March 2015 and the duty to register has applied since 1 April 2015. You must join the Register of Consultant Lobbyists if all of the following are true:

You lobby on behalf of a paying client, in the sense defined above.
Your organisation is registered for VAT (the threshold is currently £90,000 of taxable turnover).
Lobbying is more than incidental to your business. A firm whose work is mainly something else, such as law or accountancy, can be exempt when a communication is incidental to that main work.

Registration costs £950 a year, plus £12.50 for each quarterly return, which lists the clients you lobbied for in that quarter. At 31 March 2026 there were 247 registrants. The Registrar can impose a civil penalty of up to £7,500, and can refer cases for criminal prosecution, although the Registrar told the commission that, to their knowledge, no criminal proceedings have ever been brought under Part 1 of the Act.

Do in-house teams need to register?

No, not under the current rules. An employee lobbying for their own employer is outside the register, whether that employer is a bank, a manufacturer, a trade association or a charity. Their meetings with ministers should still appear in the quarterly transparency releases that each department publishes, because the Ministerial Code requires ministers' external meetings to be recorded and published.

This gap is the heart of the current debate. Transparency International's research, cited by the commission, found that only 4% of those appearing in departmental disclosures of ministers' meetings were on the statutory register. Consultant lobbyists make up roughly a fifth of UK lobbyists, and much of the most significant lobbying, including for government contracts, is done in-house.

What about lobbying MPs and peers?

The 2014 Act covers lobbying of government, so contact with backbench MPs and peers is outside the register. Parliamentarians are bound by their own codes of conduct, which ban paid advocacy. Writing to your MP about a constituency issue, or briefing a select committee, is not regulated lobbying.

Scotland runs a separate and wider regime under the Lobbying (Scotland) Act 2016, which covers in-house lobbyists and lobbying of MSPs. If you lobby Holyrood, check those rules separately.

What did the Ethics and Integrity Commission recommend?

Nothing in this section is law yet. In March 2026 the Prime Minister asked the Ethics and Integrity Commission (EIC), the successor to the Committee on Standards in Public Life, to review lobbying transparency. Its report, Lobbying, Business Appointment Rules and Disclosure, was published on 9 July 2026 with 37 recommendations, 22 of them on lobbying. The ones that matter most to businesses and charities:

One register for everyone. The consultant register would be replaced by an activity-based Lobbying Register. Any individual or organisation carrying out lobbying would register and file returns, in-house teams included.
More officials in scope. Contact with special advisers, directors general, directors and non-executive directors would count, as well as ministers and permanent secretaries.
Exemptions removed. No VAT condition and no exemption for lobbying that is incidental to a business's main work.
More detail, more often. Monthly returns recording the date, recipient, method and subject of each contact, including the specific legislation or policy targeted, the client and the ultimate beneficiary, and how the lobbying organisation is funded.
No register, no meeting. Government should decline lobbying meetings with organisations that have not registered.
Informal contact recorded. Conversations on WhatsApp and at party conferences would be included in departmental releases where they lead to follow-up.
Graduated fees and bigger fines. Fees on a sliding scale, from zero or a nominal sum for small charities up to the largest for global companies. The commission suggested a tenfold increase in the maximum fine, to £75,000, as a starting point for discussion.

The commission did not create a carve-out for charities or think tanks, on the grounds that they also exert real influence. It also kept some activity out of scope: consultation responses, petitions, requests for factual information, private citizens raising issues on their own behalf, and contact with MPs and local councils.

It proposed phasing the new register in by risk. Former ministers, special advisers and senior civil servants would go first, alongside existing consultant lobbyists. In-house lobbyists working for companies would follow, with charities and not-for-profits in the final tranche.

What happens next?

Most of this needs a new Act of Parliament. Some pieces do not: the commission noted that bringing special advisers into scope can be done by secondary legislation, and that departments can publish their transparency data in one searchable place without any new law.

As of 19 October 2026 the government had not published its response. In September the government said it was considering the case for legislative reform carefully. Separately, Baroness Hayter's Lobbying Transparency (In-house Lobbyists) Bill, a Lords private member's bill that would bring in-house lobbyists onto the register, had its second reading on 3 July 2026 and is waiting for committee stage. Private members' bills rarely become law without government support, so the government's response is the thing to watch.

What should your organisation do now?

You do not need to change anything legally today. A few steps will put you in a stronger position whatever the government decides.

Check whether you are in scope already. If you are an agency or consultancy lobbying ministers for clients and you are VAT registered, you probably need to be on the register now. The register is public, so you can also check that any agency you hire is on it.
Start keeping a contact log. Record the date, who you spoke to, how, and what about, including the bill or policy you were raising. That mirrors what the proposed returns would ask for, and it is good practice for board reporting anyway.
Read the transparency releases. Departments publish ministers' meetings every quarter. They show which organisations are getting time with ministers on your issue, which is useful competitive intelligence for any business or campaign.
Treat conferences as on the record. If the proposals go ahead, a conversation with a minister at a party conference that leads to a follow-up would be logged by both sides. Our party conference guide covers how to make those conversations count.
Keep using the open routes. Consultation responses and select committee evidence stay outside the proposed register, and they are often the most effective routes in. See our guides to responding to a government consultation and writing a policy briefing.

Frontbench tracks the legislation, debates and consultations that matter to your organisation, so you see the moment the government responds or the in-house lobbying bill moves. See how it works.
