A Visual Electrical Inspection is a brief survey of an electrical installation. It is a quick way of identifying defects, damage or deterioration of the electrical installation and to verify compliance with the current BS7671 electrical safety standard. This type of inspection does not involve any circuit testing therefore will not absolutely verify the installations safety but will give a good initial indication.
You may want a Visual Electrical Inspection if you are considering the purchase of a new property. The report will give you a reasonable indication of the condition of the electrical installation in the property. This information may help towards you making an informed decision on whether to purchase the property and whether the electrical system will need repair or upgrading.
If you are renting a property, a visual inspection report could be used as an interim measure until a formal Electrical Installation Condition Report (formerly: Periodic Inspection Report) is carried out.
