InstallerSHOW is a UK trade event for the installation and building-services community, bringing together products, solutions, and professional audiences across heat, water, air, energy, and the built environment. The show spans HVAC, plumbing, electrical, building materials, and kitchens and bathrooms, combining exhibition, live demonstrations, education, and face-to-face business connection.

The show is positioned as the UK's complete installation ecosystem under one roof. For 2026, the event is structured around four focus areas: InstallerSHOW Core, InstallerELECTRIC, InstallerBUILD, and InstallerK&B, alongside co-located activities and conference content designed to support product discovery, networking, and industry learning.
