26 year old Benjamin Little and 29 year old Matthew Little will serve a combined total of 8 years.
They first came to attention after officers became aware that they were hiding drugs in the gardens of their neighbours.
After building up a detailed picture of their criminal enterprise, they were arrested in September.
Investigating Officer, PC Jacob Robertson, said; “The Little brothers had no regard for the negative affect their drug-dealing had on the local community, and were just interested in making money for themselves.
“They will now have to pay for their crimes and spend over four years each in prison. If you bring drugs into Surrey, we will pursue you and bring you to justice wherever possible.
“If you suspect drug-dealing in your neighbourhood, please report it to us as soon as possible; this intel is a crucial part of us building a complete picture of any criminal activity.”
