How we score brands
Efficiency (SCOP): Seasonal Coefficient of Performance - higher is better
Reliability: Based on industry reports and installer feedback
Installation: Ease of installation and flexibility
Support: After-sales service, parts availability, UK network
Value: Cost vs performance, post-grant pricing
Overall: Weighted composite score
