About us

KSP Consultancy LLP was founded in 1976 as King Sumners & Partners and underwent a minor name change in 1985 to King Sumners Partnership. At this time the Practice operated from offices in Portsmouth, Salisbury and Winchester. In 1991 a new head office was opened in Fareham, while the Practice retained a satellite office in Winchester. KSP relocated to new premises in Segensworth, near Fareham in 2009. For 40 years the Practice has provided consultant services to many varied clients from a wide range of sectors.

We are committed to providing our clients with a consistently focused and professional service, individually tailored to their own specific requirements. Our aim is to deliver the best service possible on each and every project.

The Partners and each member of our highly professional team appreciate the value of every commission, large or small and we believe that this is appreciated by many of our clients who return to us again and again. Our client retention and positive referral record is excellent.
