Who we are

The UK Quality Ash Association (UKQAA) represents the producers and users of coal-fired power station ash and biomass ash products.

Launched in 1997, we’re a membership body that represents everyone involved in the production and use of coal ash in the UK. We offer technical guidance and support and work with a range of organisations to promote and encourage the use of this unique material throughout the construction and engineering sectors.

More recently, the UKQAA has also extended its membership to include organisations producing and using biomass ash and biomass ash-based products.

Anyone who has an interest in coal and biomass ash and products derived from these materials – from producers to specifiers, hauliers, suppliers, contractors and academic institutions – is welcome to join the UKQAA.

What we do

We promote the use of coal ash and biomass ash in the UK. Through technical support and advice and by offering exhibitions, seminars and training courses we aim to increase the understanding and use of both forms of ash and their products.

On this website, you’ll find information relating to our activities, including case studies, datasheets and technical specifications, but if there’s something you’re interesting in finding out more about, please contact us.
