Heard was ‘a resident gentleman of the borough’ of Kinsale, whose ancestors had arrived in county Cork from Wiltshire with Sir Walter Raleigh in 1579 and then settled in Bandon.
For many years Heard exercised ‘considerable influence’ over the parliamentary elections for Kinsale, where many of the electors were his tenants. He presented himself as a force for moderation, announcing in 1837, ‘much as I detest toryism I detest radicalism more’.
He is only known to have sat on one committee, on the Edinburgh and Glasgow Railway bill in May 1854, although the following year he gave evidence to the inquiry into postal arrangements in Waterford and Cork.
Heard retired at the 1859 general election, soon after the politically controversial bridge over the River Bandon had been completed at a cost to himself of £6,200.
