I thank the honourable member for the question. What I can guarantee is that every single cheaper home battery has been installed under the Small-scale Renewable Energy Scheme, which is one of the world's most rigorous schemes for compliance, which has been operating under governments of both persuasions and ministers of both persuasions and has ensured the safe rollout of more than four million rooftop solar installations and more than half a million cheaper home battery installations.

The member refers to complaints about cheaper home batteries. I can confirm that this scheme has received 315 complaints in relation to the Small-scale Renewable Energy Scheme, which covers solar panel installations, battery installations and solar hot water installations. That is 0.04 per cent of 800,000 installations in the last 12 months. Of those complaints, 106 matters were referred for other enforcement and 17 matters have needed to be progressed for formal investigations. That's 17 out of more than 530,000 cheaper home battery installations and 800,000 others. That's 0.002 per cent of installed systems referred for formal investigation and 0.01 per cent referred to other enforcement agencies.
