Certification and Documentation

<h2>The three certificates</h2>

<h3>Electrical Installation Certificate (EIC)</h3>
<p>Issued after initial verification of a NEW installation or major alteration. Requires three separate declarations:</p>
<ul>
<li><strong>Designer</strong> — confirms design complies with BS 7671</li>
<li><strong>Constructor</strong> — confirms installation carried out to the design</li>
<li><strong>Inspector</strong> — confirms inspection and testing carried out and results satisfactory</li>
</ul>
<p>On small jobs, all three may be the same person — but each role must be separately declared and signed.</p>

<h3>Minor Electrical Installation Works Certificate (MEIWC)</h3>
<p>For minor additions or alterations that do not include a new circuit. Examples: adding a socket to an existing ring, replacing a light fitting, adding a spur. One signatory (the person carrying out the work). Not suitable where a new circuit has been added.</p>

<h3>Electrical Installation Condition Report (EICR)</h3>
<p>For periodic inspection of EXISTING installations. Produced by an inspector/tester — no constructor declaration needed. Contains classification codes (C1/C2/C3/FI) and an overall result (SATISFACTORY or UNSATISFACTORY).</p>

<h2>Schedule of test results</h2>
<p>Attached to the EIC or EICR, recording for each circuit:</p>
<ul>
<li>Circuit description and reference</li>
<li>Cable type, CSA and reference method</li>
<li>Overcurrent device type, rating and Icc</li>
<li>RCD type, rating and operating time</li>
<li>Continuity results (R1+R2, R2)</li>
<li>Insulation resistance</li>
<li>Polarity confirmation</li>
<li>Earth fault loop impedance (Zs)</li>
<li>PFC/PSCC</li>
<li>RCD test results</li>
</ul>

<h2>Key exam points</h2>
<ul>
<li>EIC = new work. MEIWC = minor additions. EICR = periodic inspection.</li>
<li>EIC needs three declarations — MEIWC needs one</li>
<li>EICR result: SATISFACTORY or UNSATISFACTORY (C1/C2/FI = unsatisfactory)</li>
<li>Schedule of test results is a legal document — must be accurate</li>
</ul>
