CES has evolved over three generations.

In 1948 Ronald Stanley Smith left the Navy, where he was working as an engineer, to begin his career as an electrical engineer. By the late 1960s he had started his own electrical business and was working in many of London's most prestigious buildings.

Ronald invited his son, Graham Smith, to join the family business and by the late 1980s, when Ronald retired, Graham took the reins. The company was re-branded as C.E.S. (Complete Electrical Services) in 1991.

The late 1990s saw a big shift in the company with Graham developing C.E.S. from electrical contractors to a specialist lighting design & build company. C.E.S. was fortunate to play an active role in the Millennium Lottery scheme, where it worked alongside English Heritage to 'light up historic buildings'.

Ryan Slessenger and Grant Ashworth, both nephews to Graham, began their apprenticeships with C.E.S. in 1995 and 1999 respectively. With the exception of Ryan serving as an Electrical Officer for two years on the mission ship, MS Logos II, both have worked their way through the company.

In 2013 Ryan and Grant were invited to become a Partners of C.E.S. and continue the company’s development ahead of Graham's retirement. Two years later, Graham retired from CES and his son, Craig Smith, was later approached to join Ryan and Grant as the company's third Partner. Like his cousins, Craig also began his career at CES as an apprentice.

Ryan had been developing C.E.S. from a solely design & build company into a professional design consultancy practice, with Grant focusing on the specialist electrical installation services. The Partners elected to rename C.E.S. to 'CES Lighting and Electrical Specialists LLP' to reflect the new direction the company had taken.

The company today has a dedicated lighting design team with active development within the industry, who create design specifications suitable for approval and tendering purposes.

The installation team, led by Grant and Craig, carry out a whole range of electrical works whilst continuing to develop staff and apprentices to work in this specialist sector.
