What Our Customers Say
4.9 out of 5 based on customer reviews across East Anglia.
Green Hat installed 14 panels and a home battery for us. The team was professional from survey to commissioning. Our electricity bills have dropped from £140 to £30 per month, and we're earning from the Smart Export Guarantee. Genuinely transformative.
Had a 5kW system fitted on our period property near the high street. Green Hat handled the planning considerations with real expertise. System has been generating brilliantly — even through the winter months we're seeing meaningful savings.
We replaced our ageing oil boiler with a Daikin heat pump. Green Hat managed the entire BUS grant application and the installation was completed in three days. Our home is warmer than it has ever been, and we've eliminated our oil delivery costs completely.
Green Hat fitted a 50kW system on our grain store roof. The team understood agricultural buildings and worked around our harvest schedule. The system is generating significant income and has been running flawlessly since installation.
We wanted the full package — solar panels, battery storage, and an EV charger. Green Hat designed a system that powers our home and charges our EV almost entirely from solar. The monitoring app shows we're 85% self-sufficient in summer.
Whole-house renovation including heat pump and underfloor heating throughout. Green Hat coordinated everything expertly. The house is incredibly comfortable — even, consistent warmth in every room. The £7,500 BUS grant made it very affordable.
