Event marketing agency pitch process explained for UK brands

What to take away

Most UK event marketing pitches move through four stagesan introductory call, a written brief, a proposal with costs and a shortlist presentation.
Send the same written brief to every agency, and keep the list to three to five names.
Ask for creative development, delivery and on-site staffing to be shown as separate quote components, with VAT status stated.
Data handling and advertising claims carry duties from the first meeting, not from the point of signature.
Give agencies a decision date, then tell every one of them the outcome.

How the pitch process usually runs

The sequence below is the common pattern for brand-side pitches in the UK.

Introductory call:The brand explains the event objective, audience, likely scope, budget range and known dates. The agency checks whether the work is a fit and identifies questions to resolve.
Written brief:The brand sends the same brief to each agency, covering objectives, audience, requirements, constraints and the decision timetable. Agencies clarify any points they need to price and plan the work.
Proposal with costs:Each agency responds with its recommended approach, delivery plan, responsibilities and an itemised quote. The brand compares proposals against the same brief and quote format.
Shortlist presentation:Shortlisted agencies present their proposals and answer the brand's questions. The brand assesses them against the brief, makes its decision and informs every agency of the outcome.

What pitch etiquette looks like

Etiquette in this market is mostly about parity. Every agency should hold the same information, answer the same questions and work to the same deadline.

Withholding the budget range produces proposals that cannot be compared. Give a range, even a wide one, and say what it must cover.

Keep the shortlist tight. Three to five agencies is workable for a marketing team with a day job to run.

If you want finished concepts, expect to pay a pitch fee. Put that in the brief so agencies can price the work honestly.

Tell the unsuccessful agencies why they lost. Two lines of feedback protect the relationship for the next tender.

A brand in England hiring its first agency will find the process informal next to a public sector tender.

What the brand supplies at each stage

The table sets out the split of work at each stage.

Introductory call:The brand supplies its objectives, audience, likely scope, budget range and known dates; the agency checks fit and raises initial questions.
Written brief:The brand supplies the same written brief and requirements to every agency; each agency checks its understanding and asks for clarification.
Proposal with costs:The brand supplies any agreed clarifications and comparison criteria; each agency returns its proposed approach, delivery plan, responsibilities and itemised quote.
Shortlist presentation:The brand supplies the presentation format, attendees and decision date; each shortlisted agency presents its proposal and answers questions.

What to put in the brief and the pitch deck

A brief that answers these questions saves a round of emails and gives you proposals you can compare.

What should the event or campaign achieve, and how will the brand judge whether it worked?
Who is the audience, and what should they experience or do?
What format, location, dates and expected scale should agencies plan for?
What is the budget range, and what must it cover?
Which tasks will the agency handle, and which will the brand or another supplier handle?
What brand, accessibility, sustainability or operational requirements must the proposal meet?
What attendee data may be collected or used, and what advertising claims or approvals need to be considered?

The pitch deck should make the agency's idea, delivery plan, responsibilities, measurement approach and quote clear against those requirements.

Fees, VAT and what a quote should show

Agency quotes usually mix creative development, delivery and a day rate for on-site staff. Ask every agency to use the same format so totals compare line by line. Request separate quote lines for each component and any additional expenses, so you can see what is included and compare like with like.

Say whether the figures include VAT. The VAT rates published on GOV.UK set the standard rate most agency fees carry.

For work running beyond a few months, compare a retainer versus project fees before signing, because the two structures price risk differently.

Data, advertising and the rules behind a pitch

If an agency handles attendee lists during the pitch, it acts as a processor and the brand remains the controller. The ICO's UK GDPR guidance sets out the duties on each side, including what belongs in a contract. Where the agency processes personal data for the brand, agree written data-processing terms that meet the UK GDPR's Article 28 requirements before sharing attendee data.

Creative that runs must meet the advertising codes published by the ASA, whatever the channel.

Contract terms matter too. Agree who owns the creative, how cancellations are treated and what happens if the event moves.

Common questions

How long does a UK pitch take?

Plan for four to eight weeks from brief to decision, and allow longer for complex campaigns. Put the timetable in the brief and hold to it.

Should we pay agencies to pitch?

Only if you ask for developed creative. A pitch fee is fair when agencies produce concepts, and it tends to lift the standard of what you receive.

Do we have to share the budget range?

Yes, or at least a range. Agencies cannot build a realistic plan without a number, and proposals built on guesswork are hard to compare.

What if an agency asks for attendee data early?

Keep it to anonymised or sample data until contracts and processing terms are agreed. Full lists should not move before then.
