Voltoo is an independent Dutch platform that helps homeowners and businesses find and compare installation companies for energy and climate solutions. Its directory covers more than 4,000 installers across the Netherlands, including specialists in electric vehicle charging stations, heat pumps, solar panels, home batteries and air conditioning. Users can search by service, province, brand, postcode or company, then review each installer’s contact details, service area, specialisations, customer reviews and certifications.

To make comparisons clearer, Voltoo gives each listed company a score from 0 to 100 based on reputation, certifications, profile completeness and range of services. The platform also highlights credentials such as InstallQ, SCIOS and Techniek Nederland. Its knowledge base offers articles and practical guidance on costs, subsidies, regulations, energy savings and equipment brands, helping users make informed choices. Voltoo says its service is free for visitors, does not sell enquiries or take commission on quotes, and allows installation businesses to register or claim their profiles. Users can contact selected installers directly and compare options before deciding.
