Councillors have voted in favour of moving to full elections every four years.
Hertsmere Borough Council has voted for a change to elect the whole council every four years instead of the current system of electing councillors by thirds in three years out of four.
Council leader Councillor Morris Bright, recommended the authority accept the change at an extraordinary meeting earlier this evening, while Cllr John Graham seconded the motion.
30 councillors voted in favour of the change, while six councillors voted against. There were no abstentions.
Cllr Ann Harrison, leader of the Labour party, said she had serious reservations about the changes.
Local residents were asked to vote on whether to move to whole council elections or stay with the current system of elections by thirds.
During the three month public consultation, which was promoted on the council's website, Facebook and Twitter, 77 people had their say- 50.4 per cent wanted to change to whole council elections and 49.6 per cent wanted to stay with the current system of elections by thirds.
The first full council election will be held on May 7, 2015.
