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

Coal ash, may be used in ‘Bound’ or ‘Unbound’ applications. Bound refers to the use of coal ash in concrete, blocks and bricks. Unbound applications are projects where coal ash is used as a direct aggregate, such as embankment development or other engineering projects. In both case, they are subject to regulations.


As part of the European Waste Framework Directive (WFD), the UKQAA, Joint Environmental Programme (JEP), Energy UK, WRAP and the Environment Agency (in England and Wales), have agreed a protocol for the use of coal ash in bound applications.

Launched in 2010, the Quality Protocol for PFA & FBA (England & Wales and Northern Ireland) defines an agreed set of criteria for when coal ash ceases to be waste and can be used in building materials – without the necessity of obtaining waste exemptions and licences. This protocol not only ensures material produced during the combustion process at coal-fired power stations can be recovered and used for construction but ensures that coal ash products are compliant with strict industry standards and regulation controls.

The Environment Agency published a Regulatory Position Statement (RPS 108) – ‘Civil engineering activities involving grouts or other media for the purpose of sealing or ground stabilisation’ (see link below). This general document outlines how grouts may be used without the need for an environmental permit, but notes the requirement for waste protocols and gives the Quality Protocol for PFA & FBA as an example.

For information on specific applications for bound coal ash products which meet the Quality Protocol, please see our Technical Guidance page, Best Practice Guides and the UKQAA brochure.


The Environment Agency published a Regulatory Position Statement (RPS 172)‘The regulation of the use of unbound pulverised fuel ash and furnace bottom ash’ (see link below). This document explains how to use ash in unbound applications without having to apply for licences and permits in England and Wales.If you’d like to find out more about the Quality Protocol or Regulatory Position Statements please visit the Environment Agency’s website for the latest information.

Please note that the above regulation does not apply in Scotland due to the differences in Scottish law and the interpretation by the Scottish Environment Protection Agency (SEPA). Further information on SEPA’s approach to classifying coal ash can be found at


We encourage anyone with an interest in coal ash and coal ash products to consider becoming a member of the UKQAA.

There are two categories of membership: Full Members and Affiliate Members. If you wish to become a member, please see the following information about the different types of membership and fill out one of our application forms.

Applicants for Full membership will also be required to give a short presentation to the Executive Committee about their interest in the UKQAA and their connections with the coal and biomass ash industry. We’ll then assess what level of membership would suit you best. Details of the rules and benefits of membership can be provided upon request.

If you would like to get in touch about becoming a member please fill out our contact form or call us on 0121 354 5550

Full Members

Full membership is for those who own and operate coal fired power stations or are ash managers who work on behalf of a coal fired power station.
