About Big Data LDN

Big Data LDN is a technology industry event taking place September 22–23, 2027 in London, United Kingdom. It runs for two days, opening on Wednesday and closing on Thursday. With more than 11 months to go, there is time to plan the booth, the budget and the meetings properly. The dates were checked against the official show website.

Shows like this one typically draw IT leaders, engineers, product managers, founders, channel partners and technology buyers. For registration, exhibitor packages and the floor plan, go to the official website, bigdataldn.com.

What to expect at Big Data LDN

Technology shows move fast and reward clear demos. Visitors are technical, skeptical of buzzwords, and often attend with a list of problems they want solved. Expect deep questions at the booth and a strong pull toward live product walkthroughs.

Two days go by quickly. Book your most important meetings for the first morning, when visitors are fresh, and keep the second afternoon for follow-up conversations at the booth. Expect most visitors to be IT leaders and their colleagues, often with a short list of suppliers they want to see.

How exhibitors should prepare for Big Data LDN

Here is a working timeline counted back from the opening day, September 22, 2027:

1. 16 weeks before (Jun 2, 2027)
   Confirm your booth space and read the exhibitor manual. Book hotels in London while rates are still normal.
2. 8 weeks before (Jul 28, 2027)
   Order booth services (power, internet, furniture, cleaning) before the early-rate deadlines, and send graphics to print.
3. 4 weeks before (Aug 25, 2027)
   Ship freight to the advance warehouse if the organizer offers one. Book meetings with the visitors you most want to see. Set up lead capture and train the team on it.
4. One week before (Sep 15, 2027)
   Confirm freight arrived, share the staffing schedule, charge every device, and test your lead capture app with Wi-Fi turned off.

Preparation tips for technology shows

• Prepare a two-minute demo that works offline; venue Wi-Fi at large tech shows is crowded and unreliable.
• Book meetings with target accounts two to four weeks out, since decision makers fill their calendars before they arrive.
• Have a technical teammate on every shift so detailed questions do not end the conversation.

Booth tips for Big Data LDN

• Lead with the problem you solve in plain words, then show the product; feature lists alone do not stop technical visitors.
• Run demos on a large screen facing the aisle so a small crowd can watch while one person drives.
• Note the visitor's current tools and timeline with each lead; those two details shape the whole follow-up.
• Give every person on the booth a clear role (greeting, demos, qualifying) so nobody waits for someone else to start a conversation.
• Capture every conversation the moment it ends: scan the badge or card, add a one-line note about what the visitor needs, and rate the lead hot, warm or cold. Notes written that evening are already half forgotten.

Following up leads after Big Data LDN

Most of the value of a trade show is created after it closes. Tech buyers usually involve several people, so send material they can forward internally: a short summary, a demo recording and a clear next step.

1. Within 24 hours (by Sep 24, 2027)
   Send a short personal email to every hot lead. Mention one detail from your conversation so they remember you.
2. By Sep 26, 2027
   Send everything you promised at the booth: prices, samples, demo links. Log each lead in your CRM with its rating and notes.
3. By Oct 7, 2027
   Make a second, useful touch: a case study, a short video or an answer to the question they asked. Warm leads often reply to this one.
4. By Oct 23, 2027
   Review results: how many leads became meetings, what each lead cost, and whether Big Data LDN is worth returning to.

Getting to London

London has several airports: Heathrow (LHR), Gatwick (LGW) and London City (LCY), which is the closest to ExCeL London in the Docklands. The Elizabeth line stops at Custom House for ExCeL and links Heathrow with central London. Contactless bank cards work on the Tube, buses and trains. Many visitors now need an Electronic Travel Authorisation (ETA) before traveling to the UK, so check the rules for your passport.

Hotels closest to the venue sell out first during show week, and many organizers offer discounted room blocks that close weeks before the show, so book early. Our city travel guides cover hotels, transport and budgeting for the busiest show cities.
