PS: Although minor motoring offences (e.g. speeding) aren't normally regarded as part of a 'criminal record' (even though they are offences under criminal law), any imprisonable offence forms part of such a record..
You will need to keep your criminal record in mind when applying for visas for foreign travel or when applying, for example, for household insurance. (You will almost certainly face higher premiums or rejection of your application for insurance). The Rehabilitation of Offenders Act means that your criminal record can eventually be ignored for most purposes in the UK (although you might still have to declare the conviction for certain types of employment applications throughout your life) but you will have to declare your conviction, when required, on all visa applications for the rest of your life.
