First of all, please read this and update your thread accordingly: -
https://www.ftla.uk/civil-penalty-charge-notices-(councils-tfl-and-so-on)/read-this-first-before-posting-your-case!-this-section-is-for-council-tfl-dartme/We do see quite a few cases caused by late updating of the address on a V5C, some cases the update even being years late, yes really ! Your case is about 2 months late, so an OOT may succeed, but as you might know, OOTs give the right of objection to the enforcing authority, who invariably do so.
Can you tell us how you updated your V5C, online or postal ?
BTW you won't receive any enforcement documents to your current address, because the authority have to use the address provided by DVLA and use it for all of the enforcement documents. Once bailiffs are instructed, they search out where the PCN recipient has gone and serve a Letter of Enforcement.
