Braintree scraped a rare away win to restore hopes of surviving the drop.
Heybridge's defeat leaves Colin Hill's men nervously looking over their shoulders as the desperate fight to avoid the drop gathers pace.
After an even first 40 minutes, Braintree edged in front just before the interval. Danny Shipton's corner was missed by defender Daryl Bourgeois and James Baker stole in for the opener.
With renewed confidence going into the second period, the Iron extended their advantage when Baker's centre was finished by Andy Porter.
Heybridge halved the deficit with 20 minutes remaining as Charlie Bull set up Neil Cousins who beat Paul Rutherford with ease.
Late chances for James Robinson and Graeme Tomlinson might have brought the hosts a share of the spoils, but Braintree held firm to claim an impressive derby win that takes them to within four points of safety.
