Most people contact venues too early. They fire off enquiries with half the details, get back vague quotes they can’t compare, then spend weeks chasing clarifications that could have been avoided with thirty minutes of upfront work.
An event brief changes that. Not a glossy document or a formality — just a clear record of what you’re planning, what you need, and what you can spend. It means every venue you contact gets the same information, their proposals are directly comparable, and you’re not fielding the same questions five times over.
The difference between a useful brief and a wasted one comes down to knowing what venues actually need from you versus what’s helpful background for your own planning. Most of the essential information fits on a single page. Everything else builds on top.
Key takeaways
Venues need six things to quote accurately — event type, date/times, guest count, layout preference, catering approach, and budget range. Everything else is useful but secondary.
Share your budget upfront — even a rough range helps venues prepare relevant proposals. Without it, larger briefs often go unanswered.
Direction beats precision — you don’t need every answer nailed down. Knowing you want a standing format even if you haven’t chosen between canapés and bowl food gives venues enough to work with.
Send to 3–5 venues, not 15 — targeted enquiries with a proper brief get faster, more detailed responses than scattergun emails with half the information.
Six pieces of information. Without these, venues either can’t respond or give you numbers so vague they’re useless. This is the core of your brief — everything a venue’s sales team needs to check availability, confirm capacity, and put together a proposal that reflects what you’re actually planning.
Event Brief Essentials
Include these six items for a useful venue quote
Event type, format, and any distinct phases
Date, start/end times, and setup access needed
Guest count (or range) and preferred layout
Catering approach and service style
Budget range — even approximate helps
AV, production, or special requirements

Event type and format
A product launch needs different things from an awards dinner. The event type tells venues which spaces to consider, what setup is involved, and whether their venue is genuinely suitable. Include the format: is it a seated conference, a standing reception, a dinner with entertainment? If the event has distinct phases (a daytime conference followed by an evening drinks reception, for example), spell that out. Venues price and plan around the full shape of the day.
Date, times, and access requirements
The date checks availability. But times matter just as much. A venue available on your date might not work if you need setup access from 7am or want to run until midnight. Include when you need to get into the space, when guests arrive, and when everything needs to be cleared. If you have any flexibility on dates, say so. It opens up options and can affect pricing.
Write the overview section last. It’s easier to summarise your event in two lines once you’ve thought through everything else. Lead with the event name, date, type, format, and your name and contact details.
Guest count and layout
These go together because layout determines how many people a room actually fits. A space that holds 200 theatre-style might only take 120 in cabaret. Give your expected number (or a range if you’re still confirming), note whether numbers might increase, and state your preferred layout. If you’re not sure which layout works best, describe what guests will be doing — “seated watching presentations with table space for notes” tells a venue more than “cabaret, I think?”
Our layout guide covers each option in detail, including capacity conversions and when to choose cabaret over banquet.
Catering approach
Venues need to know whether you want their in-house catering, plan to bring your own, or haven’t decided yet. The service style matters too. A three-course seated dinner is a fundamentally different operation from standing canapés, and it affects which rooms work, staffing, and cost.
You don’t need a finalised menu at brief stage. Direction is enough. “Standing reception with canapés and a drinks package for two hours” gives a venue everything it needs to quote. “We want food” does not. Even vague preferences help — if you know you want guests seated but haven’t decided between plated and buffet, say that. Venues and caterers can advise on what works best in their space once they understand the shape of the event.
Dietary requirements: you don’t need exact numbers yet. Note that you’ll collect specifics closer to the event — venues expect this. A rough indication (“expect 10–15% vegetarian, will confirm allergies two weeks before”) is plenty at enquiry stage.
Budget range
Share it. A range is fine (“£15,000–20,000 for venue and catering”) but give venues something to work with. Without a budget, venues are guessing: they might propose their most expensive package when you needed their most efficient, or not respond at all because they can’t tell whether the enquiry is realistic for their space.
This isn’t about locking yourself in. It’s about getting proposals you can actually use. Venues that know your budget can offer creative solutions — different room configurations, adjusted catering packages, midweek dates that bring the price down. Venues working blind tend to send generic rate cards.
The only time to hold budget back is when you’re dealing with a single supplier you don’t trust. When you’re comparing 3–5 venues through a platform like Venues.London, sharing your range works in your favour — venues compete on what they can offer within it.
The six essentials above go directly to every venue you contact. But there’s a second layer of information that’s just as important: it shapes which venues you contact in the first place. This is what you need to know yourself (and share with anyone helping you search), but it doesn’t need to appear in every enquiry email.

Location and access
Where in London works for your guests? If most attendees are travelling from the City, a venue in Hammersmith creates friction. If people are coming from across the UK, proximity to a mainline station matters more than a specific neighbourhood. Note your preferred areas and any hard constraints — “within 10 minutes’ walk of a major tube station” is the most common filter for London corporate events.
Venue style and type
A tech company launching a product wants a different space from a law firm hosting a client dinner. The venue’s character should match the event’s purpose and your organisation’s brand. Think about what impression the space makes: modern and creative, traditional and prestigious, industrial and stripped-back? This is subjective, but naming it, even roughly, helps narrow a search of hundreds of venues down to dozens.
Must-haves vs nice-to-haves
Separate these clearly in your brief. “In-house catering, capacity for 200 theatre-style, Central London” might be non-negotiable. “Natural daylight, outdoor terrace, views” might be preferences you’d trade for the right space at the right price. Knowing which is which saves time — yours and the venue’s.
What to Flag Early
Some requirements don’t affect whether a venue can host your event, but they can flag issues or restrictions before you’re too far down the line. Include these in your brief and venues will surface problems early rather than two weeks before the event.
AV and production
If you need more than a projector and a microphone, say so. Specify screens, staging, confidence monitors, live streaming, multiple microphones, lighting rigs — whatever the event requires. Some venues include basic AV in their packages; others charge separately or require you to use approved suppliers. Events with significant production elements (a product launch with video content, a conference with live streaming) should flag this upfront because it affects room choice, power supply, and cost.
Setup and breakdown time
A simple standing reception might need an hour. A gala dinner with staging, lighting, and custom décor might need a full day. Venues charge for access time, and some spaces have back-to-back bookings that limit how early you can get in. If you know you need the room from 7am for a 9am start, or need to strike everything by 11pm, include it.
Entertainment, décor, and external suppliers
If you’re bringing in a band, a DJ, photo booths, floral installations, or branded signage, mention it. Venues may have noise restrictions, load-in constraints, rules about fixtures to walls, or approved supplier requirements. Raising this early avoids discovering a dealbreaker after you’ve signed a contract.
Check approved supplier lists before booking dry hire venues. Many have a fixed list of permitted caterers — if you want to use your own, confirm they’re allowed. Suppliers who know the venue well also tend to deliver smoother events. See our dry hire guide for the full picture.
Building the Full Brief
Everything above gets you a solid venue enquiry. But a complete event brief serves a broader purpose: it’s the reference document that keeps your team, suppliers, and stakeholders aligned throughout the planning process. These sections won’t go to venues, but they’ll save you time and prevent things falling through the cracks.
Purpose and goals
Why is this event happening, and what does success look like? This sounds corporate, but it’s genuinely useful when decisions need making. If the goal is “generate 30 qualified leads from networking,” that shapes the format differently from “celebrate the team’s achievements.” Specific goals make trade-offs easier — you’ll know whether to prioritise the venue’s wow factor or its breakout room provision.
Think about it from two angles: what does the organisation want (revenue, brand awareness, team culture), and what will attendees get from it (learning, networking, recognition, entertainment)?
Audience
How many, but also who. Internal or external guests? Seniority level? Industry? VIPs requiring special consideration? A team away day for junior staff needs a different setup from a client dinner with C-suite executives. This context helps venues recommend the right service level and helps your team make decisions about everything from dress code to catering.
Day schedule
Map out the event from setup to breakdown. What time does registration open? When are sessions, meals, breaks? When does the event end? When must everything be cleared? This doesn’t need to be minute-by-minute at brief stage — a rough timeline is enough. You’ll refine it as planning progresses.
Event name, date, type, format, coordinator contact
Budget breakdown
You’ve already shared a range with venues. The fuller breakdown is for internal planning: how the total splits across venue hire, catering, AV, entertainment, décor, and contingency. Typical splits vary by event type, but most corporate events allocate 30–40% to catering and drinks, 15–25% to venue hire, and 10–15% to AV and production.
Always include 5–10% contingency. Unexpected costs happen — last-minute guest additions, equipment needs, weather contingencies for outdoor elements. That buffer prevents budget stress and keeps you from having to renegotiate with suppliers mid-planning.
Roles and responsibilities
Who’s the event lead? Who holds budget sign-off? Who’s handling communications, supplier coordination, and on-the-day logistics? Document this early. It prevents the “I thought you were handling that” conversation three days before the event.
Include mobile numbers for anyone needed on event day. Email isn’t fast enough when you need to solve problems at 8am on the morning of a conference.
Booking timeline.
Work backwards from your event date. When does the venue need to be confirmed? When do invitations go out? When are final numbers due? For most corporate events up to 200–300 guests, a timeline of brief → shortlist (1–2 weeks) → venue confirmed (2–4 weeks) → invitations (6–8 weeks before) → final numbers (2 weeks before) works well.
For larger events, the maths changes. 300+ guests need six months’ lead time on the venue. 500+ guests — or large Christmas parties at sought-after venues — need 9–12 months. Our booking timeline guide breaks down lead times by event type and size.
Ready to send your brief?
Search London venues by capacity, area, and features — then enquire with your brief attached.
A finished brief makes the venue search dramatically faster. Pull out the essentials — event type, date, guest count, layout, catering, budget — and use those as your search filters. On Venues.London, you can filter by capacity, area, features, and event type, then enquire directly with your brief attached.
Contact 3–5 venues, not 15. Targeted enquiries with a complete brief get faster, more detailed responses. Venues take well-written briefs seriously because they signal a real event with a real budget, not a speculative tyre-kick.
When proposals come back, compare like-for-like. What’s included versus charged extra? Is the pricing a flat hire fee, a minimum spend, or a per-head package? What are the payment terms and cancellation policy? A brief that gave every venue identical information makes this comparison straightforward — which is the whole point.
Before confirming, visit your top two or three in person. Photos don’t show everything — acoustics, natural light, access routes, and general atmosphere all matter. Our venue hire questions guide has a full checklist for site visits so nothing gets missed.
Hold dates at one venue only. Give them a clear decision timeline (typically 48 hours to 2 weeks depending on demand). Holding multiple venues creates admin headaches and damages your reputation with venues you ultimately turn down.
Frequently asked questions
Yes. Even a 20-person dinner benefits from a one-page brief covering the essentials — event type, date, guest count, catering, budget. It prevents forgotten details and makes handover easier if someone else needs to pick up the planning.
Start with what you know, including any preferences however vague. Mark undecided items as TBC. “Standing format, catering style TBD” is far more useful than waiting until every detail is locked down. You can update the brief as decisions are made — the point is to give venues enough to respond to.
An event brief covers everything about your event — goals, audience, schedule, budget, suppliers, roles. A venue brief is the section you extract specifically for venue enquiries: event type, date, guest count, layout, catering, and budget. Think of the venue brief as the outward-facing subset of the full document.
Three to five is the sweet spot. Enough to compare options and create competition, few enough that you can give each venue proper attention. Sending to 15 venues dilutes your focus and means you’re comparing proposals you’ll never follow up on. Gathering 3–5 strong options is also the foundation of effective venue negotiation.
Usually the event lead, but involve stakeholders for budget sign-off and goals. The brief should be agreed across the team, not created in isolation — decisions about format, budget, and audience often need input from multiple people before you start contacting venues.
