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 Old fuse boards or outdated distribution equipment!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.
