Electrical Inspections & Testing Kent



Electrical Testing, Inspection and Certification Kent & South London


CD Sumner are NICEIC Approved Electrical Contractors, based in Orpington, Kent and serving the Kent & South London. We offer a comprehensive electrical inspection and testing service to a wide variety of domestic and commercial clients.

A periodic Inspection is designed to reveal if any of your electrical circuits or equipment are suffering from any damage or are overloaded. We will also test for potential electrical shock risks and fire hazards as well as highlight any lack of earth or bonding or any other potential dangers. Another important element of a periodic inspection is to ensure any DIY Electrical work has been completed to meet the relevant safety guidelines.


We recommend the following time frames for Periodic Inspections

  • Domestic Installations – Every 10 Years
  • Commercial Installations – Every 5 Years
  • For Caravan Installations – Every 3 Years
  • For Swimming Pools – Annually


Other instances when a periodic inspection will be required are:

  • When letting a property to a tenant
  • Prior to completing the sale of a property
  • When buying a previously unoccupied property
