How Often Should Your Electrics Be Tested?

How Often Should Your Electrics Be Tested

Ensuring the safety and efficiency of your electrical installations is paramount.

Regular testing not only prevents potential hazards but also ensures compliance with current regulations. In the UK, the frequency of electrical inspections and testing varies depending on the type of property and its usage.

To help you better understand how often you should test your electrics, we delve into the importance of testing, the specifics of Electrical Installation Condition Reports (EICR), and the latest UK regulations to guide you in maintaining safe and compliant electrics.

The Importance of Regular Electrical Testing

Electrical installations deteriorate over time due to wear and tear, environmental conditions, and usage patterns. Therefore, regular testing helps to identify potential issues before they become serious problems, reducing the risk of electrical fires, shocks, and other hazards. It also ensures that the electrical system remains efficient and reliable, which is crucial for both residential and commercial properties.

Electrical Installation Condition Reports (EICR)

An Electrical Installation Condition Report (EICR) is a comprehensive inspection and testing procedure carried out by a qualified electrician. It assesses the condition of the electrical installations and determines whether they are safe for continued use. The report highlights any deficiencies or non-compliance with current regulations, categorising them according to their severity:

  • Code C1: Danger is present, there is a risk of injury, and immediate remedial action is required.
  • Code C2: Potentially dangerous, urgent remedial action required.
  • Code C3: Improvement is recommended, though not immediately dangerous.
  • Further Investigation (FI): Further investigation is required without delay.

How Often is an EICR Required?

The frequency of EICR depends on the type of property:

  • Domestic Properties: It is recommended that homeowners have an EICR carried out every 10 years. However, rented properties must have an EICR at least every 5 years or at the start of a new tenancy.
  • Commercial Properties: Businesses should have an EICR conducted every 5 years. However, more frequent testing may be required for high-risk environments such as factories or workshops.
  • Industrial Properties: Similar to commercial properties, industrial sites typically require an EICR every 3 to 5 years, depending on the nature of the operations and the environmental conditions.
  • Public Buildings: Public buildings such as schools, hospitals, and others should be inspected every 5 years, though more frequent inspections may be necessary depending on usage and occupancy levels.

Latest UK Regulations

The UK has stringent regulations to ensure electrical safety, and the key points include:

  • RCD Protection: The regulations require Residual Current Devices (RCDs) to be installed in most circuits to protect against electric shock.
  • Periodic Inspection & Testing: The necessity for regular inspections is emphasised, with specific guidelines for different types of properties.
  • New Installations and Alterations: Any new electrical installations or significant alterations must comply with the latest standards and be inspected upon completion.
  • Landlord Responsibilities: Landlords are legally required to ensure their rental properties are electrically safe. This includes having a valid EICR and addressing any issues highlighted in the report.

Best Practices for Electrical Safety

To maintain electrical safety, property owners and managers should adhere to the following best practices:

  • Routine Visual Inspections: Regularly check for signs of wear and tear, such as frayed wires, discoloured sockets, or flickering lights.
  • Qualified Electricians: Always employ a qualified and registered electrician for any electrical work, whether it’s installation, maintenance, or inspection.
  • Up-to-Date Records: Keep detailed records of all inspections, tests, and any remedial work carried out. This helps in scheduling future inspections and ensures compliance with regulations.
  • Safety Measures: Ensure all safety devices, such as RCDs and circuit breakers within your consumer unit, are tested regularly to confirm they are functioning correctly.


Regular electrical testing is not only a regulatory requirement but also a critical aspect of maintaining a safe and efficient property. Whether you are a homeowner, landlord, or business owner, prioritising electrical safety through routine EICRs and adhering to best practices can prevent costly damages and protect lives.
