On formal occasions the Lord-Lieutenant can be recognised by his uniform, which is based on the dress uniform of an Army officer.
The Vice Lord-Lieutenant and male Representative Deputy Lieutenants wear a similar uniform though those with former military service, in the rank of colonel or above (and its RN and RAF equivalents), may opt to wear the uniform of their service. There is no uniform for female Deputy Lieutenants, but those who have a military background, of appropriate rank, may wear the uniform of their rank and arm of the service in which they last served.
Deputy Lieutenants carrying out civic duties in civilian dress may wear a Deputy Lieutenant’s badge. England, Scotland, Wales and Northern Ireland have different badges. The English Lieutenancy badge is shown here.
