A diagnostic visit starts with the symptom, what still works and any recent change. The electrician
isolates safely, tests the most relevant point or circuit and follows the evidence rather than replacing
parts at random.
This is a standard fault-finding visit, not an emergency call-out. If there is heat, a burning smell,
visible damage or a breaker that will not stay on, go straight to the
emergency electrician page
. Standard diagnostic visits follow the
small-job pricing
, and anything wider is explained before work expands.
How the visit narrows the cause
Confirm the reported pattern and the safe-use status before testing starts.
Separate the point, connected equipment and relevant circuit so the likely cause becomes narrower.
Explain the evidence before any repair or further work is agreed.
What can only be seen after safe access
Photos and certificates help, but they cannot show everything behind a finished wall. In older London
homes, plaster can crumble when a plate is removed, walls may not be flat or square, and a back box
may be shallow or loose.
The electrician may also find short or brittle cable ends or a previous hidden joint close to the
opened point. These are practical findings, not proof that the whole installation is bad.
A useful outcome may be a confirmed local repair, a clear diagnosis with later work, or a wider
inspection or quotation. You should see the finding and agree the next step before extra work
continues.
