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 1960's 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 1980's, when Ronald retired, Graham took the reins. The company was re-branded as C.E.S. (Complete Electrical Services) in 1991.

The late 1990's saw a big shift in the company as Graham developed C.E.S. from electrical contractors to a specialist lighting design & build company. C.E.S. was fortunate to be heavily involved with the Millennium Lottery scheme to 'light-up historic buildings' working closely with English heritage.

Ryan Slessenger & Grant Ashworth, both nephews to Graham, began their apprenticeships with C.E.S. in 1995 and 1999 respectively. And with the exception of Ryan taking a 2-year period to serve as the Electrical Officer for the mission ship, the MS Logos II, they have worked their way up the company.

In 2013 Ryan and Grant were invited to become a Partners of C.E.S. and continue the development ahead of Grahams retirement. Graham retired from C.E.S. in 2015, following this Craig Smith (Graham's Son) was invited to join Ryan and Grant as the third Partner of CES. Like his Cousins Craig also began as apprentice at the company.

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

The Company today has a dedicated lighting design team with active development within the industry whom create Design specifications suitable for approval and tendering purposes.

The installation team led by Grant and Craig carry out all manner of electrical works and continue developing staff and apprentices to work in this specialist sector.
