The Haddonstone Independent Installer Scheme

Our scheme aims to provide our clients with a list of independent installers who have experience of successfully installing our products in the UK. Members of the scheme attend in-house training at our Northamptonshire manufactory, and share our values of exceptional customer service.

The highest quality and strength standards

All of our materials meet the strict levels of technical performance as defined by the UKCSA. Haddonstone has a minimum compressive cube strength greater than 35 MPa after 28 days, and TecStone’s minimum compressive cube strength after 28 days is greater than 45 MPa. This means that they exceed the requirements of BS 1217:2008, BS5642-2: 1983 + A1 2014 and BS EN 13198: 2003.
