Electrical Safety and Visual Inspections


We all take electricity and the use of electrical appliances for granted, but electrical faults cause in excess of 19% of all fires in the home and a further 25% are caused by not using electrical appliances correctly. (Electrical Safety Council)

The BESAVI® (Basic Electrical Safety And Visual Inspection) is a basic electrical test designed for Landlords, Block Managers, Holiday Cottages, Bed and Breakfasts and Owners of property who offer to share their property with use of electrical appliances. The BESAVI is designed to check the general condition of Consumer units, sockets, switches and the continuity of the earth and RCD/MCB functions if fitted. The IEE recommends in their Guidance Notes 3 Table 3:2 states that all types of electrical installations (except domestic) should be routinely tested yearly and in some cases even quarterly. By carrying out the BESAVI® you are exceeding the recommendations.

BESAVI and Portable Appliance Testing for Landlords and Letting agents.

A BESAVI® test compliments a Portable Appliance Test. Although it is called portable appliance testing and the definition in the regulations for portable is up to 18 kilos, we carry out the same test for washing machines, fridges, microwaves etc.

If the appliance is integrated in the kitchen units and connected through a switch spur fuse (not a square pin 13 amp plug) we can either carry out an earth continuity test on the item or take out the wires from the connection and fully test the item for a little extra.

If you would like further information please visit our Portable Appliance Tests website or contact us using the details provided below.

BESAVI®: Basic Electrical Safety and Visual Inspection.

Total electrical safety within the home is dependant upon the correct wiring and operation of the fixed wiring within the building. Conventionally a "Periodic Inspection Report" is carried out on the fixed wiring within your property to assess compliance with BS7671.

The Basic Electrical Safety and Visual Inspection or BESAVI is designed for customers who require an inspection of the installation at a competitive price, but without the thoroughness of the detailed and more expensive Periodic Inspection Report. Prices start from £50.00 for a BESAVI.

CESAVI®: Complete Electrical Safety and Visual Inspection.

A BESAVI® is not a substitute for a 10 year Periodic Inspection Report (PIR) it complements it and assists you in complying with IEE recommendations; we are able to quote for a CESAVI®, Complete Electrical Safety And Visual Inspection. If you are, as you should be, legally going to the expense of a PAT test, there is little point if the earthing, sockets or light fittings are in a dangerous state. The only way to be completely safe is to have a BESAVI® every year and a CESAVI® every 10 Years.

Tests carried out during the Basic Electrical Safety and Visual Inspection: include:

  • Inspection of the consumer unit including MCB / fuse ratings, condition, labelling, suitability for a domestic property and identification of circuits requiring testing.
  • Checking the operation of the consumer unit isolating switch.
  • Checking MCB (if any) operation.
  • Checking the main RCD operation using the test button(s)
  • Visually checking all easily accessible power points, switches, flex outlets and electrical fittings for damage and condition.
  • Testing the phase wiring on all accessible sockets (13 amp square pin only).
  • Measuring the main RCD trip times under various conditions and confirming that they are within the required limits (Measured from a 13 amp square pin socket).
  • Measuring the actual RCD trip current (Measured from a 13 amp square pin socket).
  • For all easily accessible 13 amp square pin sockets measuring and checking that the earth loop impedance is within the required limit.
  • Checking that a sample light switch or fitting on each identified lighting circuit has a protective earth connected.
  • Checking Smoke and Heat Detectors and also CO2 detectors where fitted.

Residual Current Devices (RCDs) are very important for safety, particularly for appliances used outside a building. If an RCD is found, that is part of a socket within the building, then the holding and trip currents will be measured to ensure that the RCD is working correctly.

Wherever appropriate the test result limits specified in BS7671 :2008 are used for the above tests. This is as specified in the Institute of Electrical Engineers Guidance Note 3 "Inspection and Testing". These are the same limits as used for a Periodic Inspection Report.

Following the BESAVI® we will present a full report and recommendations that we think is relevant to the safety of the installation.
