Electrical safety compliance is automatically notified to your Local Authority Building Control through our NAPIT membership. You will receive a formal Building Regulations Compliance Certificate upon completion.
Insurance-Backed Guarantees (IBG)
Your deposit and workmanship guarantees are protected independently, ensuring total peace of mind for decades to come.

COMMON QUESTIONS
Frequently Asked Questions About Accreditations & DNO Approval
What is a DNO acceptance letter, and why do i need one?
A DNO Acceptance Letter is an official document from your regional electricity network operator confirming that your solar/battery installation is registered and approved to connect to the National Grid.
Do i need to contact my DNO energy network supplier myself?
No. Lunar Solar handles all communications, application submissions, and technical paperwork with your DNO from start to finish.
What happens if my DNO rejects a G99 high-capacity solar application?
In rare cases where local grid infrastructure is congested, we install smart G99 export limitation devices that cap grid export while allowing 100% of generated solar power to be used inside your home or stored in your battery.
Why is NAPIT registration important for my installation?
NAPIT membership certifies that our installation team meets high electrical standards, allowing us to legally certify electrical work under Part P of UK Building Regulations and automatically notify your local council.
