The UKQAA represents a wide range of organisations involved in the production, supply and use of coal and biomass ash. Our members include coal ash producers, hauliers, manufacturers and suppliers. We also represent end-users of coal ash products for both the private and the public sector including architects, designers and specifiers.

Similarly, our membership includes a small but growing number of biomass ash producers and users.

There are two tiers of membership – Full and Affiliate. For more information on who makes up our membership, click on their links.


The objective of the UKQAA is to promote the mutual interests of its members and to encourage the use of quality ash (defined as ash products derived from combustion plants, fuelled by pulverised coal, coal/biomass co-combustion or biomass) and ensure a long term sustainable supply chain and ongoing demand.

As a Trade Association, the UKQAA provides a vehicle for members to engage with public bodies and policy makers as well as acting as an interface with other national and international bodies sharing some or all of the UKQAA’s objectives.

The representatives of the members of the UKQAA undertake to comply with the requirements of the competition and bribery laws of the United Kingdom both during meetings of the UKQAA and at all other times. The Constitution and Rules of Membership may be found in the link below
