Andrew Bigby was convicted of misconduct offences at Southwark Crown Court after bagging £60,000 worth of bungs to push through controversial planning applications and hand out false documents.
The 41-year old from Hertfordshire, described as a 'rotten apple' by the council, also used the authority's computer system to change key records.
Bigby's wife, Elisabeth, 36, a fellow Enfield Council employee, was given an eight-month jail term - suspended for two years - for helping her husband hide the money.
During the three year period, the Bigbys spent the backhanders on a lavish lifestyle, buying three cars, a new kitchen and a three-week holiday for their friends in Florida, the court heard.
A police raid on their home uncovered a cupboard full of ripped up planning correspondence and £3,000 in cash.
John Pryor, Enfield's director of environment, said: 'I am pleased Bigby has received a custodial sentence.
'We expect the highest standards of probity at Enfield council and when one rotten apple lets his standards slip the reputation of hard-working officers is tainted.'
