Customers consistently highlight a straightforward, well-managed process from initial enquiry through survey, design and commissioning, with the online portal, clear documentation and handling of BUS grant and DNO paperwork frequently praised. Surveys are described as thorough and data-driven, and the performance guarantee gives reassurance, though a few reviewers wanted more detailed design breakdowns or faster admin responses. Installers are widely described as knowledgeable, punctual, tidy and respectful of the home, with neat workmanship and clear handovers. Communication during the install is a recurring strength, and most systems are performing as designed, with only occasional snags reported.
