Buy Your Own Weed-Mapping Drone, or Hire a Specialist?
A number of software companies are now selling farms a drone and an AI subscription, pitched as a replacement for hiring a survey contractor. Here is what that actually costs, compared honestly against paying a specialist per hectare.
The full cost of doing it yourself
Several agri-tech platforms now sell an entry-level mapping drone alongside an AI weed-detection subscription, giving farms the option to run their own surveys. The software can produce a good weed map — but the total cost of ownership goes well beyond the software subscription itself.
| Cost item | Buying your own kit | Hiring a specialist |
|---|---|---|
| Drone & sensor hardware | From around £3,650 for an entry-level mapping drone bundle, more for multispectral sensors | £0 |
| CAA pilot certification & insurance | Roughly £1,000–£1,500 to get legally certified and insured to fly commercially | £0 |
| AI weed-mapping software subscription | Typically £17–22/ha every year, indefinitely | Included in the survey fee |
| Flying, processing, and interpreting the data | Your own time, weather-dependent, every survey | Not your time |
| MPA weed detection survey | — | One cost-effective flat fee per survey, quoted for your farm — nothing else to buy |

A worked example: 300 hectares, three years
Take a 300ha arable farm doing one weed-mapping survey a year. Buying the kit means roughly £4,650–£5,150 upfront for the drone and certification, then £5,100–£6,600 a year in software subscription alone at £17–22/ha — before a single hour of your own time flying and processing the data. Over three years, that's somewhere around £19,950–£25,050 in direct costs, plus the time.
Hiring a specialist for the same 300ha survey, at typical contractor day-rates, works out significantly cheaper than that over three years — with no equipment to buy, maintain, or insure, no certification to hold, and none of your own time spent flying or processing data. For a single farm doing one or two surveys a year, the DIY route rarely closes that gap. Ask us for a quote specific to your acreage to see the exact comparison for your farm.
The maths changes if you are already a contractor flying several thousand combined hectares across multiple clients each season — at that scale, owning the kit can make sense. For a single farm business, it very rarely does.
Why the method matters, not just the price
Most DIY weed-mapping platforms run on a trained AI model. MPA's detection method is rule-based rather than AI — every detection has a specific, auditable spectral basis, validated against the full-resolution image before delivery. That means the reasoning behind every detection can be shown and explained, which matters when the map is being used to justify a treatment decision to an agronomist, or as evidence for an SFI26 PRF2 claim.
It also means you are working with someone who flies, processes, and interprets the data as their day job — rather than software you need to operate and interpret yourself.
