What We're All About

CTA Purpose

Certass Trade Association recognises the lack of support for the local tradesperson.

Several associations and federations exist, but they usually work to favour the commercial interests of their larger members.

The CTA’s purpose is to redefine your expectations of a glazing association & become the membership body of choice for modern construction excellence. By offering leading service and innovation across the sector to local installers and the wider construction industry that helps companies expand, improve and profit.

We are fully geared to work for the modern SME through an entirely digital delivery. This means we are accessible to all our members, whenever and wherever they need it.

The CTA is excited to represent you and is fully committed to providing members with a united voice within this thriving industry.

Key Personnel

CTA is about you not us, but we thought you would like to know a little about the people you’ll be hearing from. 

We pledge to collaborate with others who exemplify our core principles dedicated to improving the industry. To champion those who perform well, helping local businesses progress and flourish whilst improving engagement between contractor and consumer.
