Did Britain really host more than a thousand major exhibitions in 2024? Yes — but that does not mean only 1,145 exhibitions of every kind took place across the country. It means the Events Industry Alliance's Size and Scale Index for Exhibitions (SASIE) estimated 1,145 exhibitions and conferences at the UK's main exhibition venues, attracting approximately 7.2 million visits during calendar year 2024. The distinction between a defined survey population and every possible event is crucial. An independent craft fair, a specialist supplier showcase in a hotel and a major trade exhibition do not necessarily appear within the same research frame.
The story has moved on since that 2024 snapshot. In an August 2026 release about the 2025 exhibition market, the same industry alliance reported 1,154 exhibitions, almost 6.8 million visitors, 139,000 exhibitors and £11.7 billion in total economic output. More events but fewer visits? It is possible, and it is an excellent reason to look beyond a single upbeat percentage. This analysis asks what those industry figures measure, what they do not, and how a UK exhibition venue can use them intelligently.

What exactly does the SASIE exhibition count include?
SASIE is the Size and Scale Index for Exhibitions, a recurring research series commissioned through the Events Industry Alliance (EIA), which brings together the Association of Event Organisers, Association of Event Venues and Event Supplier and Services Association. Its 31 March 2025 statement announcing the SASIE 2024 report says the exercise draws on participating industry members and analyses a weighted set of data. The index concerns exhibitions and conferences held at the UK's main exhibition venues; it is not a census of all temporary markets or every community event.
When someone repeats the 1,145 figure without the qualifying words, two things get lost. The first is coverage: smaller events in unconventional spaces may sit outside the sample. The second is event definition: conference events with exhibitions can be included alongside trade and consumer shows. This matters if you are comparing a small town venue with a national exhibition hall. The broad market provides useful context, but the venues serve quite different clients and must not be treated as interchangeable.
It also matters that the 2024 in the SASIE 2024 title refers to observed event activity, whilst the public EIA announcement appeared in March 2025. The newer figures describe 2025 activity and were published in August 2026. Neither publication date should be passed off as the date the events themselves took place.
How many visitors attended, and are visits unique people?
The EIA's 2024 account places attendance at approximately 7.2 million visitors. Its later 2025 study reports almost 6.8 million visitors. The visitor headline is an estimated exhibition attendance measure associated with the industry's research methodology, rather than a national count of unique residents who have ever visited an exhibition. A single professional might visit several exhibitions or return on more than one day; without the underlying attendance definition, it would be unsafe to claim every recorded attendance is a separate person.
The basic arithmetic is revealing but limited. Taking the published rounded figures at face value, 7.2 million divided by 1,145 events gives roughly 6,300 visits per recorded exhibition in 2024. Almost 6.8 million divided by 1,154 gives a little under 5,900 in 2025. These are calculations from national totals, not published 'typical event' attendance. A few very large consumer exhibitions can lift the average, whilst many specialist shows serve a much narrower audience. Neither figure is an appropriate attendance target for an ordinary meeting room or modest regional venue.
A useful venue decision therefore starts with comparable exhibitions. An engineering supply show, for example, may attract a concentrated industry audience, require machine loading and use visitor registration mainly for trade visitors. A leisure-oriented consumer event may have busier weekend entry peaks and substantially different requirements for queues, catering and public transport. Their headcounts alone say little about operating cost, commercial quality or suitability for a space.
Is the exhibitions market growing — or changing shape?
The EIA's original SASIE 2024 announcement reported that exhibition numbers rose about 4% compared with 2023, reaching the highest level since 2017. Visitor numbers grew about 3% over 2023. It also reported trade exhibitions above pre-pandemic volumes, consumer exhibitions still below their earlier level, and conference-with-exhibition formats growing. A venue could therefore see a healthy trade-show sector without seeing an equivalent recovery in every consumer-facing category.
The later 2025 figures show 1,154 exhibitions, compared with 1,145 in 2024, but the rounded visit total is lower. That is not automatically a contradiction or evidence of collapse. The mix and size of exhibitions, length of shows, types of attendees and estimation methods all influence the series. The careful interpretation is that the alliance reported slightly more exhibitions for 2025, with fewer total visits than in its earlier headline. A responsible comparison should use unrounded tables and check whether the participating venue set, weighting and definitions were consistent before claiming an exact percentage change.
Seasonality makes the story still more useful for venue teams. EIA reported that March, September, October and November accounted for about half of exhibitions in 2024. For booking managers, peak months create competition for suitable build days, parking, loading arrangements, staff and contractors. Rather than simply seek higher volume, a venue might decide to price operationally intense dates more carefully or attract smaller events into quieter periods. Any such decision needs local enquiry and cost evidence, not just the national calendar.
What is the difference between £11.5bn and £11.7bn?
In September 2025 the EIA published an economic impact study of the 2024 exhibitions market, reporting £11.5 billion in business sales or economic output, more than 126,000 jobs supported and £6.0 billion in GDP contribution. Its subsequent 2025-market release, published on 20 August 2026, estimated £11.7 billion total economic output and more than 127,000 jobs.
Economic output, GDP contribution and direct spending are different accounting ideas. Output can include business-to-business sales as activity moves through the exhibition supply chain; GDP or gross value added is not the same calculation, and direct spending is narrower than a study's modelled total impact. The later EIA study reports approximately £5.3 billion direct spending in 2025. You should not add that to £11.7 billion as though it were independent money, or describe the larger number as the ticket income of exhibition organisers. Equally, the modelled jobs measure does not mean that many people are employed full-time by exhibition halls themselves.
The difference between the two years' £11.5bn and £11.7bn estimates is modest in nominal terms. Without checking both studies' complete economic modelling and inflation treatment, claiming a precise real growth rate would be unwise. A hall considering expansion should rely on prospective contracted demand, costs, room and loading capacity and its own sales pipeline rather than multiplying EIA's economic impact by the venue's share of exhibition floor area.
Why exhibitors matter as much as visitor footfall
An exhibition brings together at least three commercial audiences: the organiser, the exhibitor and the visitor. The organiser usually purchases space and related facilities under an agreement with the venue, then sells participation and may coordinate admission. Exhibitors invest in stand space, display equipment, freight, staffing and sales follow-up. Visitors spend time and money to attend, sometimes travelling across borders. These groups overlap operationally but they do not have identical objectives or spend the same way.
The EIA's 2024 economic research cites around 132,000 exhibiting companies in the activity covered by that study; the 2025 release identifies around 139,000 exhibitors. These describe annual exhibitor participation in a research population, not 139,000 separate companies that would all be willing to hire a venue. Similarly, EIA's 2025 economic model estimates £84,493 of total economic output per exhibitor, a calculated impact measure, not a guarantee of sales or return on investment to a business purchasing a stand.
For a venue, a financially attractive trade exhibition may require excellent loading, accessible circulation, resilient electrical systems, safe stand construction, strong mobile connectivity and sensible overnight security. At a different event, audience registration and catering dwell time may be more important than freight. The right operational offer depends on what organisers and exhibitors need, not a simplistic ranking by visitor count.
How a smaller exhibition venue can benchmark intelligently
Start by defining the competitive set: similar floor area, ceiling height, public transport access, loading capacity, fire and safety conditions, available accommodation and event types. Compare venue hire, build and breakdown days, average revenue per booked day, staffing and security commitments, consumables and equipment maintenance. A site that can comfortably run a two-day regional trade fair might not be able to replicate a national show at a much larger centre, however attractive the market headline appears.
Then separate three kinds of measurement. Demand includes qualified enquiries, repeat organisers, contracted exhibitor requirements and realistic attendance. Operations includes total occupied days, changeover times, loading conflicts, accessibility needs and incident rates. Commercial performance includes income actually retained, contribution after direct costs, deposits, cancellation risk and unpaid supplier work. Put all three beside the national SASIE trends rather than letting a single attendance estimate dominate the plan.
A realistic venue quotation should also make the inclusions visible. Organisers need to know exactly which hours, rooms, access routes, waste arrangements, electrical supplies, cleaning, registration facilities and event support are included. Precise scope makes the venue easier to compare and reduces the risk of assuming that important services are free. National research can justify studying the market; it cannot substitute for a detailed, deliverable contract.
What should operators watch in the next research release?
More than an eye-catching total, watch for changes in venue coverage, trade versus consumer show mix, exhibition size and duration, attendance per show, exhibitor participation, floor area sold and the busiest booking months. Find out whether economic claims refer to direct expenditure, total output or GDP contribution. Ask whether the current estimate uses the same research boundaries as the previous year. Where it does not, record the break instead of drawing a straight trend line through it.
In short, the verified picture is a sizeable UK exhibition market, with EIA reporting 1,145 main-venue exhibition and conference events and 7.2 million visitors for 2024, followed by 1,154 exhibitions and almost 6.8 million visitors for 2025. The later impact study estimates £11.7 billion of total output and over 127,000 jobs associated with the sector. These are meaningful industry indicators. For a venue, however, the decision that matters is much more specific: which exhibitions can your building serve reliably, at what true operating cost, and with what repeatable customer benefit?
