Not sure which fair fits your business?
Answer a few quick questions and we will match you with trade fairs that suit your industry, budget and goals.
How to choose between these fairs
Size is not the same as fit. A fair with a very large visitor count can be a poor match if only a small share of visitors buy what you sell.
- Check who attends. Some fairs are mainly for trade visitors, others open to the public on certain days, which raises the headline number.
- Book early. Stand space and hotels for the largest fairs go first, so start planning 6 to 12 months ahead.
- Consider smaller fairs. A focused fair with fewer, qualified buyers often beats a giant one. Browse all Energy & Environment exhibitions to compare, or use the exhibition matcher.
