Yes, heat pumps, solar PV, solar thermal, and battery storage are all recorded in your EPC assessment. Under RdSAP 10 they’re modelled in more detail, but your rating is based on calculated running costs, not carbon savings, so the actual impact varies by system.

• Heat pumps can improve your rating if they replace a less efficient heating system.
• Solar PV is modelled on system size, orientation, and overshading, and is likely to help your rating.
• Battery storage is recorded but currently has little effect on the score.
• Solar thermal can help by offsetting hot water demand.

Planning to install renewables? It’s worth checking with a qualified assessor first on how the improvement is likely to show up in your rating.
