Why are we recommending our drone assets?

Simply put, we cover a wide area but we don’t offer a national coverage. Some of our own customers and other businesses we deal with often ask what drone they would need, as they find it easier to have their own drones they can use as and when they need to, for their own work – rather than getting an external contractor in every time and racking up expenses and time taken to capture data.

If you need a drone for your business and want to use it whilst staying compliant, we recommend UAV Hub for training any prospective remote pilots. If you are responsible for your employees but will not be flying, we recommend you at least take some basic training so you are aware of the relevant legislation and guidance on flying drones for commercial purposes.

We recommend UAV Hub as we’ve used it and other drone training companies, this one comes out on top each time. Click the button below to check them out:
