The thing most people do not realise
Of the operators currently listed in this directory, more than half either state on their own website, or are publicly listed as, flying application work under another company's CAA operational authorisation rather than their own. That is not a criticism of any of them. It is the single most common structure in UK agricultural drone work, and once you know it exists, a lot of the market makes more sense.
Two roles, two different things
UK drone rules separate two roles that people casually treat as one.
- The UAS operator is the legal entity responsible for the flight and the holder of the operational authorisation. This is who the CAA has assessed.
- The remote pilotis the person actually flying, working within that operator's authorisation, procedures and manual.
In a network arrangement, the business that quotes you and turns up on the day is the remote pilot. The UAS operator is somebody else. Both parts are legitimate. They are just not the same party, and if something goes wrong the distinction stops being academic.
Why networks exist at all
Agricultural application drones are heavy. A DJI Agras T50 or an XAG P100 Pro is well over 25kg once loaded, which puts it outside the standard PDRA01 permission and into bespoke authorisation territory based on a Specific Operations Risk Assessment. Under the 2026/27 CAA charges that means a fee running from £2,422 at the lowest assessed risk level to £17,300 at the highest, an annual renewal, and a safety case most people pay somebody to help them write. Then you wait.
So a sensible thing happened. Companies that had already done the work opened it up, and individual operators joined them. The full cost picture is in what it really costs to start a drone spraying business in the UK.
The networks operating in the UK
Two are visible in this directory. Both publish their arrangements, which is how we are able to describe them here.
| Network | Authorisation held by | How it works |
|---|---|---|
| AutoSpray Pilot Network (ASPN) | AutoSpray Systems Ltd, CAA OA UAS 14429 | By far the largest. AutoSpray is the UAS operator of record for application work and ASPN pilots act as authorised delivery agents. Members are typically XAG equipped and trained through AutoSpray. |
| SAS Agri Drones | SAS Agri, authorised in its own right with the DJI Agras T50 | Smaller. SAS describes local teams across eleven UK locations and advertises agricultural drone franchise opportunities. Spray work by member businesses runs under the SAS authorisation. |
There are also operators flying entirely in their own right, including businesses that hold their own authorisation for heavy application work, and businesses that fly survey and mapping under their own PDRA01 while doing application work through a network. That last combination is more common than people expect, and it is perfectly coherent.
What a network covers, and what it does not
This is the part that gets muddled most often, so it is worth being blunt. A CAA operational authorisation permits the flight. It says nothing about what you are allowed to put through the tank.
Applying a plant protection product from the air is aerial spraying, which is prohibited in the UK unless the Health and Safety Executive grants a permit against an approved application plan. There are currently no commercial authorisations for drone applied pesticides, only a small number of trials permits. Being in a network does not change that for anybody. It is a separate regime with a separate regulator, and any operator who blurs the two is worth a second look. Our legality guide covers this in full.
If you are hiring: three questions
You do not need to become an expert. You need three answers, and any competent operator will give them without hesitation.
- Who is the UAS operator of record for this job, and what is the authorisation reference?
- Does your insurance cover this specific work, and can I see the certificate?
- What exactly are you applying, and under what permission is that product allowed to be applied by drone?
An operator who answers those three clearly is telling you they have thought about the job properly. There is a longer list in what to ask before hiring a drone operator.
If you are joining: what to weigh up
Joining a network removes the largest cost and the longest delay in setting up, which is why most people start there. What you are giving up is being the operator of record, and that has consequences worth thinking through before you sign anything.
- Ask what the joining and ongoing costs are, and whether equipment purchase is tied to membership.
- Ask whether you can work outside the network, and whether there are territory restrictions.
- Ask what happens to your customers if you leave, and who owns the job records.
- Ask who carries the insurance and where your liability sits.
- Ask what the network will do for you when a job goes wrong, since that is the moment the arrangement is actually tested.
None of these are gotchas. They are the questions any franchise style arrangement deserves, and a good network will have clear answers ready.
Which operators fly under a network
Where an operator has published its arrangement, or a network lists it publicly, we record it in the regulatory notes on their listing. You can see it on any profile in the operator directory. We think it is one of the more useful things on a listing, because it answers the responsibility question before you have to ask it.
If you run an agricultural drone business and your listing does not say this yet, or says it wrongly, claim your listing and we will correct it. If you are not listed at all, you can add your business.

FAQs
What is a drone pilot network?
One company holds a CAA operational authorisation for heavy application drones and other businesses fly under it as authorised pilots. The company holding the authorisation is the UAS operator, the legal entity responsible for the flight. The business you hire may be the pilot rather than the operator.
Does flying under a network make an operator less legitimate?
No. It is the normal structure in this market and it exists because a bespoke authorisation for an aircraft over 25kg is slow and expensive to obtain. What matters is that the arrangement is real, current and clearly explained. An operator who volunteers it before you ask is usually the one who has it in order.
Who is responsible if something goes wrong on my field?
For the flight itself, responsibility sits with the UAS operator of record named on the authorisation, not necessarily the business that quoted you. Ask who that is, and check the insurance covers the specific work being done rather than general business activity.
Does a network authorisation let an operator spray pesticides?
No. A CAA operational authorisation permits the flight. Applying a plant protection product from the air is aerial spraying and needs a separate permit from the Health and Safety Executive. There are currently no commercial authorisations for drone applied pesticides in the UK, only a small number of trials permits.
Should a new operator join a network or get their own authorisation?
Most start in a network, because it removes the biggest cost and the longest delay in setting up. Getting your own authorisation makes sense once you have the volume to justify it, or when being the operator of record is commercially important to you.

Network arrangements were checked in September 2026 against operators' own published information. Arrangements change. Confirm current permissions, insurance and product suitability directly with the operator before work is arranged.
