Katalysis design and build good looking and hard working websites for clients locally and further afield.

We aim always to produce websites that are carefully considered, beautifully designed and that will fully deliver your objectives.

Most of our websites are built with Concrete5 - a simple and powerful content management system that makes your web site easy to manage and provides a strong framework for custom development.

Katalysis is a Concrete5 Certified Partner Agency and, in fact, we were the UK's first official Concrete5 Services and Hosting Partner as long ago as 2008. We've have been building all kinds of websites using this fantastic content management system ever since.
