About Us


Our Ethos

Ever since our establishment in 1972, collaboration and teamwork has been at the heart of the SDC philosophy and we believe that this represents one of the major factors behind the continued success of the business. This overriding philosophy, combined with exacting management processes and highly professional teams, is a hallmark of the SDC culture and a key reason why clients regard us as the standout choice when selecting a main contractor.

How we operate

SDC undertakes projects across a variety of construction sectors, including research and development, commercial, manufacturing, automotive, healthcare, and education. Offering such a diverse spectrum of service has enabled us to move with – and adapt to – changing market trends, resulting in controlled growth for the business in spite of the recent recession. We have a turnover £165m this financial year (ending September 2017) up from £91m in 2012! This sustained growth is aided by the fact that a large proportion of our work is awarded on a repeat order basis from an extensive and ever growing client base.


What is most unique about SDC, however, is that our group of companies operate under the umbrella of an Employee Benefit Trust (EBT) – the first of its kind in the British construction industry. This means instead of being owned by shareholders, the future of our company is protected by a Board of Trustees who are responsible for safeguarding the long-term prosperity of SDC and sharing any profit amongst members of staff and the wider community. Find out more about how the EBT was formed here.
