How much it costs to exhibit

Preparing your visit

For the exhibitor

• 12 months out: book the floor space and choose the hall/world (Water or Energy) according to your offering.
• 6 months out: stand design, service-provider brief, ordering of utilities and technical services.
• 3 months out: complete the online exhibitor listing, book appointments via the digital platform, press plan.

For the decision-making visitor

Target in advance the halls matching your priorities (sanitation/bathrooms on the Water side, heating/renewables on the Energy side), pre-book the key conferences and organise your supplier meetings via the official platform. Allow at least two days on site given the size of the trade show.

Policy & CSR initiatives

Sustainability is a defining theme of ISH, whose "The Power of Solutions" positioning highlights water- and energy-efficient solutions (energy efficiency, renewables, drinking-water hygiene and conservation). The organising group Messe Frankfurt runs a formalised sustainability programme (EMAS validation, Net Zero Carbon Events commitment signed in 2022, carbon-neutrality target for the Frankfurt site by 2040) applied to its venues and events. The specific CSR commitments for the 2027 edition are detailed on the official website in the run-up to the trade show.

How the trade show has evolved

Trajectory analysis

ISH retains its status as the world's leading trade show for water and building energy, with a highly international visitor base (150 countries in 2025) and a predominantly foreign exhibitor base (72%). The editorial trajectory is shifting markedly towards decarbonisation: heat pumps, renewables, energy efficiency and smart building management on the Energy side, water conservation and hygiene on the Water side. The new focuses announced for 2027 (green roofs and façades, swimming pools and spas, integrated solutions) confirm the show's broadening towards a holistic approach to sustainable buildings.
