Where can a home battery go? Loft, garage or outside
Checked by our MCS-certified installers · Updated October 2026
Short answer
Not in the loft. The UK's battery safety guide says a home battery goes outside where it can, or in a garage or suitable room.
Never in a loft, a bedroom, or on the stairs, hall or landing — your way out in a fire. We pick the right spot with you at the free survey.
