I'd be amazed if they gave you prison for that. However, if/when you are banned, you will also get a licence endorsement, which means that your conviction won't be spent for five years. So, it will be shown on any basic DBS checks done in that time. Once it's spent, it's no longer relevant for insurance, so you can either insist your insurer disregards it, as they have a legal duty to do, or other insurers are available.
As the offence can be filtered, it would be removed from a standard or enhanced DBS check 11 years after the date of conviction.
As Chris Stacey said: Although its not formally part of the sentence that is handed down in court, the criminal record that someone comes away with effectively becomes a second sentence, which can have a long-lasting, if not lifelong, impact.
