A fine Adam Marriott header in the 12th minute was supplemented by a Jacob Hazel double in the 17th and 20th minutes.
Although Kettering struck back five minutes before the break through Remaye Campbell and four minutes afterwards through a trialist, Tony Weston wrapped up United’s win in stoppage time.
