London has no shortage of AI events in 2027, but more choice does not guarantee a better calendar. The useful question is whether you need practical case studies, technical depth, buyers, research debate or a stronger professional network.
I have narrowed the list to eight distinct stops and treated co-located shows as one trip. That gives you a cleaner route through the year.
1. AI Powered Insights Conference 2027
21 JANUARY 2027 | 15 NORTHBURGH STREET, LONDON
The Market Research Society starts the year with a focused look at AI agents, synthetic data and AI-native insight teams. I would choose it if you work in customer research and want honest examples of changed workflows, quality controls and human oversight.
2. AI and Society: Ethics, Creativity and Power
30-31 JANUARY 2027 | BIRKBECK, UNIVERSITY OF LONDON + ONLINE
This interdisciplinary conference examines how AI changes ethics, creativity, power and society. It belongs on your list if your work touches public policy, responsible AI, culture or the human consequences of automated decisions.
3. TechEx Global 2027
3-4 FEBRUARY 2027 | OLYMPIA LONDON
TechEx Global brings eight enterprise technology events together, including the co-located AI & Big Data Expo. I would use this broad programme to compare AI, data infrastructure, automation, cybersecurity and digital transformation in one visit.
4. Big Data & AI World London 2027
10-11 MARCH 2027 | EXCEL LONDON
Big Data & AI World focuses on enterprise adoption, data governance, model transparency and responsible AI. Data leaders and technology buyers should attend with a shortlist of platforms or governance problems they need to evaluate.
5. QCon London 2027
13-16 APRIL 2027 | QEII CENTRE, LONDON
QCon is the engineering-heavy option, with practitioner-led coverage of agentic AI, multimodal systems, RAG, MLOps and AI infrastructure. I would send senior developers, architects and engineering leaders who need production patterns rather than sales pitches.
6. Digi-Tech Pharma & AI 2027
11-12 MAY 2027 | LONDON
Digi-Tech Pharma & AI applies digital technology and machine learning to drug discovery, pharmaceutical operations and clinical development. This is the specialist choice for pharma leaders, data scientists, clinical teams and technology vendors who need domain-specific conversations.
7. The AI Summit London 2027
9-10 JUNE 2027 | TOBACCO DOCK, LONDON
The AI Summit is built around commercial strategy, deployment, governance and scaling. I would prioritise it for executives, enterprise AI teams, founders and investors who want partnerships, demonstrations and conversations about business results.
8. Women in AI Global Summit 2027
11-12 NOVEMBER 2027 | GROSVENOR STREET, LONDON
Women in AI brings women and allies together around AI, machine learning, robotics, automation and spatial computing. I would choose it for professional connections, visible role models and a broader view of the people shaping the field.
Which London AI event should you attend?
Senior engineers should start with QCon, while CIOs and AI programme leaders should compare TechEx, Big Data & AI World and The AI Summit. Researchers working on insight methods should choose the MRS conference, and pharma professionals should go directly to Digi-Tech Pharma & AI.
Policy researchers and responsible AI specialists should look closely at AI and Society. If community and career development matter most, Women in AI offers the clearer fit.
