National Sprayer Testing Scheme: Frequently Asked Questions
Why Is A Testing Scheme Needed?
Before the national scheme, the A.E.A. ran a sprayer testing scheme to meet various requirements, including assurance schemes, processor/retailer production protocols as well as satisfying the desire of many farmers to verify the accuracy and overall fitness of their pesticide application equipment. Experience showed that more than half the sprayers tested required repairs or adjustment to achieve the required standard.
Therefore, under The Voluntary Initiative*, a commitment was made by the agricultural and horticultural industries to extend sprayer testing to cover the majority of field sprayers operating in the UK. As a consequence the A.E.A. and the farming unions, together with other key stakeholders have developed and introduced the National Sprayer Testing Scheme (N. S. T. S.) an independently validated testing scheme to meet this need. Since November 2016, testing has also been a legal requirement (see below).
Who Does The Test?
The test will be undertaken by a Test Centre and conducted by a trained examiner who holds a valid N. P. T. C. level 3 certificate of competence.
What Are The Benefits of Testing a Sprayer?
There are two main benefits:
Firstly, it ensures maximum efficiency of your sprayer, reduces costly downtime, aids trace ability and increases second hand value. The cost of replacing worn jets that deliver only 5% more than the recommended rate (typically equal to £5.75 / ha in winter wheat) is readily recovered in agrochemical savings and improved efficacy resulting from better and more consistent spray quality.
Secondly, a valid certificate provides evidence to your clients, crop assurance organizations and the general public of your commitment to keep your machines in a sound, well serviced condition.
Can The Test Be Done On My Farm?
Yes – provided you dispose of any wastewater under the terms of the Groundwater Regulations.
What Does The Test Cover?
The Test Covers:-
Delivery System – Tanks and lids, pump, spray controls, pipe work and hoses.
Application System – Pressure gauges, spray lines, nozzle bodies, check valves, spray caps and tips, booms and suspension.
Ancillaries – Rinsing and tank wash systems, re-circulation systems and chemical induction systems.
Can All Types of Application Equipment be Tested?
Yes – Although primarily aimed at hydraulic field sprayers most application equipment can be included in the scheme including granular applicators. The scheme is also open to equipment used in the amenity, public health and industrial sectors.
Is an NSTS test a legal requirement?
Yes. Since 26 November 2016, the Plant Protection Products (Sustainable Use) Regulations 2012 have required pesticide application equipment to be tested. Boom sprayers wider than 3 metres must be tested before they are five years old and then at least every three years; sprayers with a boom of 3 metres or less every six years. If you grow under Scottish Quality Crops, sprayers more than a year old with a boom wider than 3 metres must be tested every year. We test golf, amenity and agricultural sprayers on site: tell us your machine and postcode and we will quote.
How much does an NSTS test cost?
An on-site sprayer test to NSTS standard is £690, plus £55 for the NSTS test certificate. These prices are from our November 2025 to November 2026 price list and exclude VAT.
Are The Test Results Published?
No – The confidentiality of all information, including test results, is protected under the Data Protection Act.
Who Administers The Register?
A . E . A . The Scheme’s management board is drawn from representatives from application technology, contracting, training and farming together with representatives from Government and environmental organizations. The A. E. A. administers the scheme on their behalf.
