Electrics and gas
A storage battery sits in the garage and the roof has no panels. What has the survey not operated?
Not the storage battery. The survey has not operated the battery sitting in the garage, and a bare roof means it has not found panels there to run either. It can record the cabinet it saw and that the roof covering had no panels in view. It does not switch the battery on, measure a charge, or prove what the unit feeds. A home survey is not an electrical installation condition report. Ask an electrician what the battery does, and do not invent a solar array the roof did not show.

What is the fuller explanation?
A storage battery and a solar array are different things. Panels, if they exist, were not on the roof the surveyor could see. The garage cabinet might store power from panels elsewhere, from a tariff, or from a system that is incomplete. None of that is settled by noting the box. The survey does not operate isolators as a function test and does not state a state of charge. Naming the equipment is not running it.
Ask an electrician to inspect the battery, its connections and any inverter or consumer unit beside it, and to say whether panels exist anywhere the survey could not see. Tell them the roof looked bare. Do not press buttons on the cabinet during a viewing. Keep their note with the survey so a later reader does not turn a visual record of a garage battery into a claim that a solar system was tested.
What should you ask your surveyor?
- What did you see of the battery: the cabinet only, or also isolators and cables?
- Which roof slopes did you see well enough to say there were no panels?
- Was any other generation equipment visible, or only the garage battery?
What are the typical next steps?
- Treat the report as a visual note of the garage battery and a bare roof.
- Ask an electrician to inspect the battery and say what it serves.
- Do not operate the cabinet yourself, and do not assume hidden panels.
Costs vary with the building and with who you instruct. Where this page does not cite a published figure, ask the surveyor, a relevant specialist, or your solicitor for a written quote. Do not treat a forum average as the price.
Also asked about this
Does a bare roof mean the battery is spare and unused?
No. The survey did not operate the garage battery. It can still be connected to something else even though no panels were seen on that roof.
Is naming the battery an electrical certificate?
No. A home survey does not produce an electrical installation condition report. Naming the garage battery is not a certificate, and the unit was not run.
