The National Allotment Society (NAS) is a leading UK organization for allotment holders, founded in the early 20th century. It works with governments, councils, and developers to promote and preserve allotments, highlighting their social and environmental benefits[1][2]. Services include legal advice, liability insurance, horticultural discounts, and expertise on site management[1][2]. The target audience is allotment holders and associations. The unique selling proposition is its comprehensive support for allotment preservation and community engagement, along with its advocacy role in government allotment policies[2].
