<p>I have a few questions on this—</p>
<ol>
<li><p>What is #5 &quot;<em>Corporation (other than a company) incorporated in England and Wales</em>&quot;?  Is not a company the sole form of corporation that exists in England and Wales?</p>
</li>
<li><p>&quot;<em>Principal office</em>&quot; is not defined within the Civil Procedure Rules.  Is it necessarily the <em>registered office</em> (of a company/LLP)?  Or where a company has a head office location that is different to its registered office (which might for example be that of its accountant), might the former be the &quot;principal office&quot;?</p>
</li>
<li><p>Where a company ceases to use a place of business, does that place immediately cease to be a &quot;<em>place of business</em>&quot; for them or would it remain a valid place of service thereafter?</p>
</li>
</ol>
<p>Supporting citations/references much appreciated!</p>

<li>All companies are corporations but not all corporations are companies. For example, co-operatives are Corporations but not companies. Also, most government owned (statutory) corporations are not companies.</li>
<li>"Principal office" is just what it says, the main (principal) office of the organisation. It may be distinct from the registered office for the reason you give among others.</li>
<li>Assuming the organisation still exits, it will have a new Principal Office - even if that is just the office of its liquidator.</li>
</ol>
