Founded in 1898 as Sun Engraving, the club has a proud history stretching back more than 125 years. In 1901, the club became known as Sun Sports FC, competing in the Watford & District League and West Herts League before establishing itself as a respected name within Hertfordshire football.

The club joined the Herts County League Division Two in 1947–48 and earned promotion to Division One in 1955–56. A year later, a league restructure saw Sun Sports move into the Premier Division. Although relegated the following season, the club immediately bounced back and returned to the top flight.

Sun Sports continued to build its reputation, making its debut in the FA Vase in 1977 before suffering relegation in 1980. Once again, the club responded in true Sun Sports fashion, winning promotion straight back to the top division at the first opportunity.

The early 1990s produced one of the club's most successful periods. In 1992–93, Sun Sports were crowned league champions, and they successfully defended their title the following season, establishing themselves as one of the leading sides in the area.

In 1995, the club merged with local side Watford Postal Services F.C. and adopted the name Sun Postal Sports. After finishing runners-up in consecutive seasons, the club stepped up to the Spartan South Midlands League Division One in 2003–04.

More success followed in 2013–14 when Sun Postal Sports were crowned Spartan South Midlands League Division One champions, earning promotion to the Premier Division. At the same time, the club returned to the historic Sun Sports name.

The club has also played an important role in developing young footballers through its youth setup, Sun Sports Youth FC, continuing a tradition of football in the local community.

The Road Back
The club faced some of its most difficult years after withdrawing from the Spartan South Midlands League in September 2017, following the loss of its home ground. Attempts to secure a groundshare were unsuccessful, and the club subsequently entered the Herts Senior County League.

Despite further setbacks, Sun Sports continued to fight for its place in local football. The club re-entered the Herts Senior County League as Sun Sports Watford in 2020–21, keeping the name and spirit alive through challenging times.
