Heat pump Seasonal Performance Factor (SPF) calculation template
Guidance
This document must be completed by your installer and sent to us as part of your application for the Domestic Renewable Heat Incentive, if you’ve had your heat pump’s performance reassessed.
You must do this before you apply; it's not possible to have your heat pump SPF value changed after you’ve joined. The template should be sent to us after you have applied, so that we can check it against your application number.
