Customers consistently praise a smooth, well-organised journey from survey to commissioning, with Heat Geek's online portal, clear documentation and handling of BUS grant and DNO paperwork singled out for making a complex process feel straightforward. The room-by-room heat loss surveys and design tools gave people confidence in sizing and efficiency, and the SCOP guarantee was frequently cited as a deciding factor. A few noted slower comms at points or confusion around specific steps. Installers were widely described as knowledgeable, punctual, tidy and professional, with neat pipework, minimal disruption and thorough handovers of controls and apps. Many reviewers highlighted pragmatic design choices that avoided unnecessary radiator or pipework changes, and attentive aftercare. Minor gripes included external pipework aesthetics, tariff guidance and occasional snagging, but overall recommendations were overwhelmingly enthusiastic.
