Yes, it’s highly recommended to have an Electrical Installation Condition Report (EICR) carried out before any rewiring. An EICR is an inspection that evaluates the condition of your existing electrical system, identifying any potential hazards, outdated components, or areas of concern. It’s an important step to ensure that your electrical system is safe before proceeding with rewiring. The EICR also helps us tailor the rewiring to your property’s specific needs and ensure compliance with current safety regulations.

The duration of a full house rewiring depends on the size and complexity of the property. For smaller homes or apartments, the rewiring process can typically be completed in 1 to 2 days. For larger homes or more complex systems, rewiring may take up to a week or more. We’ll provide an estimated timeframe during the initial assessment, ensuring minimal disruption to your day-to-day life.
