Approximately one mile from the town is the Heathfield transmitting station, a 145 m high mast (135 m to the bottom of the antenna shroud) which broadcasts TV and radio signals to East and West Sussex, as well as parts of south Kent.

There is an Anglo/French market called Le Marché held every year on the August Bank Holiday, and a fair that visits during the summer.

This detachment is based in the Youth Centre on High Street, and is affiliated to Princess of Wales' Royal Regiment.

The rehearsal site on Alexandra Road in Heathfield was extended and refurbished following a steady increase in band membership.

TV presenter David Dimbleby officially opened the newly extended band room on 3 September 2005.

The Heathfield Silver Band plays at weddings, garden parties, church functions, and fetes and regularly gives concerts.

During September–November they march in Uckfield, Crowborough, Mayfield, Lewes, and East Hoathly carnivals, as well as for their hometown Heathfield & District Bonfire Society.

Reformed in 2018 by a group of local enthusiasts (Founders Steve Thomas, Dave Shoebridge, Thomas Keep, Rachel Keep, Ken Brewster and Halina Keep), HDBS aims to enhance the sense of community in their town and surrounding area by holding the traditional celebration of bonfire and torchlight procession and joining in the annual season of events around Sussex representing Heathfield & District at other societies bonfire events.

HDBS hopes to put on more bonfire nights for the community and are looking forward to building on and creating more connections with local organisations, businesses & schools in Heathfield.
