Commercial Rewires

01.
About.

A commercial rewire replaces ageing, overloaded or noncompliant electrical systems with a modern installation designed to support today’s operational demands.

Swiftsure Electrical delivers full and partial rewires for offices, retail units, warehouses, industrial facilities and publicsector buildings across Kent, London and the Southeast.

Our engineers work safely, efficiently and with minimal disruption to your business, ensuring your electrical infrastructure is compliant, reliable and built for longterm performance.

02.
Why A Rewire Is Important

Commercial environments place far greater demand on electrical systems than domestic properties. A rewire ensures:

  • Improved safety and reduced fire risk
  • Compliance with the latest BS 7671 wiring regulations
  • Increased capacity for modern electrical loads
  • Better reliability and fewer faults
  • A cleaner, more efficient installation throughout the property

What’s Included in a Commercial Rewire

Every commercial rewire is tailored to the building, usage and operational needs. Our service typically includes:

  • + Replacement of all wiring, containment and cabling
    + New distribution boards and upgraded protective devices
    + Threephase power installations where required
  • + New sockets, lighting circuits and smallpower layouts
    + LED and energyefficient lighting upgrades
    + Emergency lighting and fire alarm integrations
  • + Data cabling, comms infrastructure and containment
    + Earthing, bonding and surge protection
    + Full testing, certification and compliance documentation

We coordinate with site managers, FM teams and other trades to ensure a smooth, wellplanned installation.

Signs a Commercial Building May Need a Rewire

Common indicators include:

  • ! Frequent tripping or overloaded circuits
    ! Old fuse boards or outdated distribution equipment
    ! Evidence of overheating, scorching or damaged accessories
  • ! Insufficient power for modern equipment
    ! Lack of documentation or unknown installation age
    ! A building older than 25–30 years with no major electrical upgrades

If required, we can carry out an EICR to confirm the condition of the installation before planning a rewire.
