Police in Sheffield have uncovered a cannabis farm worth an estimated £300,000 in a private rented property.

Officers in Hillsborough revealed on Thursday that they had discovered and seized the drugs den.

Cannabis farms have long been a problematic issue for unsuspecting landlords, with their rental properties occasionally converted to make them suitable for full-scale cannabis production.

These farms typically involve large scale alterations to the property, including removal of walls and changes to the electricity supply – resulting in tens of thousands of pounds of damage to a landlord’s property.

With cannabis farms still a prominent issue, buy-to-let landlords, as well as managing and letting agents, are being urged to be aware of the potential damages to the rented property and how the issue can be avoided.

“You may not be aware but the landlord will receive a hefty bill to reconnect before being able to rent out the property,” the police said. “It’s really worth being careful and vigilant if you rent out. Those landlords that are complicit can expect some focus by this team.”

The Sheffield North West Neighbourhood Policing Team said the latest drugs find took the total value of the cannabis it had recovered to more than £6m.

Nobody has been arrested in connection with the cannabis farm. The investigation is still ongoing.
