On-site notes from a Colchester electrician

Real jobs. Real faults.
No stock photos. No fluff.

Notes from the job

This is my writing and note-taking space as a working electrician in Colchester – a place to break down EICRs, real jobs, and the sort of details that don’t fit on a standard business website.

  • No sponsored rankings. No paid listings.
  • No stock photos of handshakes and perfect lofts.
  • Just the reality of testing, fault finding and upgrading installations in and around Colchester.
