Would you know how to spot a cannabis factory?

Like this one in Staines officers uncovered in 2023, cannabis factories can be hidden away behind any door, in any town. We think you’d be surprised at just where they turn up – don’t let appearances fool you!

So what does a cannabis factory look like, why are they a problem, and how can you spot the signs and report them to police?

Below are some of the signs that a property might be operating as a cannabis factory:

Cannabis factories can be very dangerous and pose a serious fire risk due to the electricity they need to run. Often this bypasses the electricity meter and leaves a lot of exposed cables and wiring, with the circuits running close to water-filled pipes.

The amount of electricity used can also destabilise your local power grid and cause electrical outages, and cannabis plants grown upstairs can also cause floorboards to rot and be in danger of collapsing.

Cannabis factories are connected to organised crime groups, which are involved in crimes such as human trafficking and exploitation.

So now you know the signs to spot, does any of this sound familiar?

If reading this list has reminded you of a house or flat or building near you, it’s possible they could be involved in the cultivation and supply of cannabis.
