He was sentenced at St Albans Crown Court after pleading guilty last November to fraud amounting to £160,000.
Robinson admitted two counts of conspiring with others to obtain a mortgage by misrepresentation from the Abbey and Halifax building societies.
Judge Andrew Bright QC described him as the instigator of the frauds, having introduced others to a fraudulent mortgage broker.
Passing sentence, the judge told him:
"This was an operation which was fraudulent from the outset and involved a significant amount of forward planning."
"I am satisfied you took part in a thoroughly dishonest course of conduct."
