The Electrical Contractors' Association (ECA) has reported the release of BSI PAS 63100:2024, a specification covering protection against fire of battery energy storage systems for use in dwellings. The ECA's report is dated 9 September 2024 and describes the document as recently released1.
The ECA sets out what the document is and what it is for:
"The recently released BSI PAS 63100:2024 - Electrical Installations: Protection against fire of battery energy storage systems for use in dwellings. A PAS (Publicly Available Specification) is a fast track standardization document aiming to define good practice standards."
The ECA states that Chris Edwards, its Technical Manager, explains the key focus areas of the standard, and offers a free download of PAS 63100:2024 through BSI's knowledge portal1. The specific focus areas themselves are not set out in the ECA report, and the technical content of the specification has not been reported in the material available here.
| Item | Detail |

The ECA report does not give a publication date for the PAS itself, only describing it as recently released at the time of writing. It also does not state whether the specification is voluntary or carries any regulatory force, and no commencement or transition dates are given1.
Why it matters for households
A home battery stores a large amount of energy in a unit that is usually fitted inside a house, a garage or an outbuilding, so how it is sited, enclosed, ventilated and isolated in the event of a fault is central to how independently a household can run it. A specification aimed at fire protection in dwellings speaks directly to that: it addresses the part of a home battery storage installation that determines whether a fault stays contained or affects the building.
For a household weighing up storage, the existence of a named standard gives a reference point when discussing an installation with a contractor, and a way to check that the standards governing home battery installation are being applied. It sits alongside wider questions about how safe home battery storage systems are and about home battery fire safety, including containment and fire service guidance. Because the ECA report does not reproduce the specification's requirements, what a compliant installation looks like in practice has not been reported here.
What happens next
No next steps are given in the ECA report. It does not state a review date, an implementation period or any date by which installers or manufacturers are expected to work to the specification1.
