- Local Exchange Trading Systems or Schemes - are local community-based mutual aid networks in which people exchange all kinds of goods and services with one another, without the need for money. LETS groups are in towns, cities and rural areas in many parts of the country.

aim to revitalise communities. As grassroots initiatives they are open to everyone - people of all ages, skills and abilities; local clubs and associations; voluntary groups, charities, community initiatives; housing co-operatives, small businesses and local services - helping everyone to give and take, connect to new resources, and find a genuine community identity.

offer equal opportunities to all - whether employed or unemployed, financially secure or on low income, black or white, able or disabled. LETS use a system of community credits, so that direct exchanges do not have to be made. People earn LETS credits by providing a service, and can then spend the credits on whatever is offered by others on the scheme: for example childcare, transport, food, home repairs or the hire of tools and equipment.
