D&C LTA enters teams in the annual LTA County Cup competitions. The County Cup events give players the opportunity to represent their County in a team competition both at national level.

The Summer County Cup is held at a variety of locations throughout the United Kingdom, normally in mid-July. The Winter County Cup is held in November, again at a variety of indoor locations across the UK. The County has a Selection Committee made up of County Captains, County Coach and Performance Lead, which is responsible for appointing Captains to each team and selecting the squad for each team.
