Kezo i sent the info you passed to me and this was their reply to part of my email, “You will receive an EIC when all works are complete. You do not require any certification from building control, the solar and air source heat pump fall under the “permitted building development rights” This will also show on your MCS certificate when this is produced.”
Thats good however, I had it in my head from your heatpump was less than a meter from your boundary?
Did you mentioned your consumer unit or getting that part itemised?
Good to hear its working well for you 🙂
