Corporate event planning checklist

Use this checklist as a working plan from concept to post-event review. It is written for London corporate organisers running team socials, client events, conferences and parties.

Direct answer: A reliable corporate event plan works through five stages — define objectives and budget, confirm venue and date, brief and book suppliers, run logistics and on-the-day operations, then review outcomes against your original goals.

1. Define the event

  1. Write a one-sentence objective (what success looks like).
  2. Agree the audience: internal team, clients, partners or a mix.
  3. Confirm approximate guest count and any hard constraints (accessibility, dietary, dress code).
  4. Set a working budget range and who signs it off.
  5. Nominate one internal owner and a small approval group.

2. Date, venue and format

  1. Identify two or three candidate dates before contacting venues.
  2. Shortlist venues by capacity, layout, access and location relative to guests.
  3. Check licensing hours, sound restrictions and load-in/out windows.
  4. Confirm what the venue includes (furniture, AV, staffing) and what needs to be brought in.
  5. Read the contract carefully — cancellation terms, minimum spend and damage deposits.

3. Suppliers to consider

  • Catering and drinks (see the caterer guide).
  • Photography or video (see the photographer guide).
  • DJ, band or entertainment (see the DJ guide).
  • AV, staging and lighting if not provided by the venue.
  • Styling, florals or branded signage.
  • Security, cloakroom and front-of-house staff.
  • Transport or accessibility support for guests.

Brief every supplier from the same source of truth. The event brief template helps you do that consistently.

4. Budget and contingency

  1. Break the budget into categories (venue, catering, entertainment, AV, staffing, contingency).
  2. Agree a visible contingency line internally, sized to the event's uncertainty and your approval rules — keep it separate from committed spend.
  3. Track quotes vs. actuals as suppliers confirm.
  4. Confirm VAT treatment and payment terms with each supplier in writing.

5. Run of show

  1. Build a minute-by-minute schedule from doors open to close-down.
  2. Share a single-page brief with every supplier: arrival, setup, timings, contacts.
  3. Assign an on-the-day point of contact so suppliers don't chase multiple people.
  4. Walk the venue with key suppliers where possible, or share plans and photos.

6. Two weeks before

  • Reconfirm timings, guest numbers and dietary requirements with every supplier.
  • Send joining instructions and access details to guests.
  • Confirm setup, sound-check and load-out windows with the venue.
  • Prepare signage, name badges, seating and any branded collateral.

7. Event day

  • Arrive before your earliest supplier for setup.
  • Hold a short pre-brief with venue, catering and entertainment leads.
  • Keep the run of show visible and note any live changes.
  • Nominate someone to greet late arrivals and manage guest questions.

8. After the event

  1. Debrief with the internal team within a week while detail is fresh.
  2. Compare outcomes to the original objective and budget.
  3. Capture supplier feedback — what worked, what to change next time.
  4. Save assets (photos, feedback, invoices) in one place for the next event.

Frequently asked questions

How far in advance should we start planning a corporate event?
It depends on scale and season. Small internal events can come together in a few weeks; larger client-facing or peak-season events usually benefit from several months of lead time so you can secure venues and preferred suppliers.
Who should own the event internally?
Assign a single decision-maker who can sign off scope, budget and supplier choices. Everyone else contributes input, but one person should own the timeline and approvals.
What is the single most common planning mistake?
Underestimating time between confirming a venue and briefing suppliers. Suppliers need clarity on space, timings and access before they can quote accurately.
