What battery storage safety documents should homeowners keep?

Safety first

Battery storage combines high electrical energy with site-specific commissioning. Buyers and insurers may ask how the system was installed and whether shutdown procedures are documented.

Documents to keep

Manufacturer manual and emergency instructions: including isolation points.

Installer commissioning and sign-off: showing the system was left configured as designed.

Building control or scheme paperwork: where notification applied.

Warranty and service plan: including any temperature or ventilation conditions.

If your battery is in a loft, garage, or outbuilding, keep photos that show clear access routes for maintenance.
