The Alpha philosophy is to provide the most comprehensive and economic services, combining the very highest standards with a “can do” attitude.

Alpha is a community enterprise business wholly owned by Catalyst, (formerly known as SAdAS), a limited company and registered charity. We hold all of the required insurances and licences required to operate.

We are a preferred contractor to Surrey and Hampshire County Councils. Any profits go back towards furthering the aims of the charity. As a community enterprise we aim to support and improve the communities we work in by being professional and ethical in our approach.
