The PK Group have signed a deal to secure the use of the first ever executive box at the Proact Stadium until the end of next season.
The Chesterfield-based company will occupy the executive box for all league games during that period.
Tony Vickerman, commercial sales & marketing director of the PK Group, said: "Being the first ever executive box at the stadium, we thought it would be nice to have it. We used the box for the first time for the Sheffield United and we couldn't have asked for more. It was a great day."
Chesterfield's sales & marketing manager Kevin Fitzgerald said: "The PK Group have been firm supporters of the club for many years and we hope that link-up will continue for many years to come.
"They are continuing to see rapid growth with a new showroom set to open in December and we are sure they will enjoy entertaining their guests in the box."
The PK Group operates in the public, commercial, industrial and private sectors, providing a range of services including electrical contracting, gas, heating and plumbing services, together with general building services and maintenance.
