The surveyor will aim to identify if there are any signs of Subsidence or Asbestos inside the property. If there are signs of either, then this is flagged in your report and you will be advised to seek specialist advice. A RICS Building Surveyor is not a qualified electrician so they cannot take apart electrical equipment in any intrusive way. They can test the electrics however the word test is defined by RICS to mean: "For the purposes of this guidance note ‘tests’ are taken to mean measures to check the quality, performance, or reliability of parts of the building. For example, ‘tests’ will typically include taking samples of the building fabric (plaster, brick, and concrete) or checking the performance of a service system (checking the safety and performance of heating appliances, electrical system, or underground drainage). The use of a moisture meter, opening and closing windows and doors, and the normal operation of service systems are not ‘tests’." The surveyor will comment on the electrics within the survey report and advise whether a buyer should employ the services of a qualified electrician to test the electrics.
