Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, whether the Future Homes Standard will make solar batteries mandatory on new build homes.

Batteries aren’t mandated under the Future Homes and Buildings Standards because Building Regulations set performance‑based outcomes and do not mandate specific technologies. This ensures flexibility for developers and avoids locking in solutions that may not be suitable in every setting.

Battery storage is permitted and encouraged, and we continue to welcome ambitious developers who choose to go further than the minimum requirements.
