Hendon chairman Simon Lawrence, a co-founder of Hendon FC Supporters Trust, the club’s owners, said: “We are very grateful to Wembley Football Club for all they have done for us in the past few years.
“Hendon is delighted to arrange this deal with our good friends at Harrow Borough.
"We have been friends and rivals, on and off the pitch, for almost 40 years and we look forward to playing on their excellent surface and enjoying their facilities in the seasons to come.”
