A new law that came into effect in April has permanently banned anyone born after 1 January 2009 from purchasing tobacco products.
The legislation means those born in 2008 represent the final cohort eligible to buy cigarettes.
The Department of Health and Social Care is now consulting on extending similar restrictions to cigars by mandating plain packaging.
Cigarette packaging has already been standardised under existing regulations, with products concealed in plain containers and stripped of promotional imagery.
Evidence suggests the measure has contributed to declining smoking rates, which have reached historic lows in Britain.
The proposed regulations would require all cigar packaging in Britain to feature an identical colour scheme.
The mandated shade, designated Pantone 448C, comprises a dull, dark, matte brown hue.
Brand identification would be restricted to three appearances on the packaging, rendered in Helvetica typeface at 14-point size, with only the initial letter capitalised.
Design elements including artwork, logos, and additional colours would be prohibited.
Observers have noted that such standardisation could potentially facilitate counterfeiting due to the simplified design.
Cigars have traditionally occupied a smaller segment of the tobacco market compared to cigarettes, typically associated with special occasions rather than regular consumption.
The consultation forms part of broader government efforts to achieve a smoke-free generation.
Officials maintain that plain packaging represents an effective public health intervention based on evidence from existing cigarette regulations.
