What Does a Weed Spraying Contractor Actually Do?
A weed spraying contractor applies herbicide to unwanted vegetation in a controlled, systematic and legally compliant way. For commercial sites — industrial estates, car parks, business parks, schools, managed properties and public spaces — this means far more than simply pumping chemical from a knapsack sprayer. A professional contractor selects the right product for the surface type and weed species present, applies it at the correct dose rate, manages the risk to drainage, people and the surrounding environment, and documents everything they do.
The result is not just dead weeds — it is a treated site with a clear evidence trail showing that the work was carried out legally, safely and to a defined standard. For commercial clients who may face scrutiny from tenants, insurers, local authorities or auditors, that documentation is as important as the treatment itself.
The Legal Framework: Why Certification Is Non-Negotiable
Commercial herbicide spraying in the UK is governed by the Control of Pesticides Regulations 1986, the Plant Protection Products Regulations 2011 and associated codes of practice. The requirements are clear and apply to any contractor applying herbicide on commercial land:
PA1 certification
PA1 is the foundation certificate for professional pesticide application. It covers the safe storage, handling and application of herbicides, emergency response procedures, legal responsibilities and environmental awareness. Every operative who carries out commercial spraying must hold PA1 as a minimum. There are no exceptions.
PA6AW certification
PA6AW extends certification to cover the application of herbicides on hard surfaces and in or near aquatic environments. This is required for any spraying on car parks, paved areas, footpaths, roads, and any site near drains, watercourses, ponds or ditches. In practice, the majority of commercial weed spraying in Kent involves hard surfaces or drainage — which means PA6AW is required for most commercial jobs, not just specialist ones.
⚠ Your risk as the client. If you instruct a weed spraying contractor who doesn't hold the correct certifications and an incident occurs — contamination of a drain, runoff into a watercourse, adverse effect on a member of the public — the liability doesn't rest solely with the contractor. As the commissioning business, you have a responsibility to ensure the contractor you instruct is legally qualified to do the work. Always request PA1 and PA6AW certificates before signing anything.

Questions to Ask a Weed Spraying Contractor Before You Instruct Them
When getting quotes from weed spraying contractors in Kent, these are the questions worth asking:
- Can you provide copies of PA1 and PA6AW certificates for the operatives who will carry out the work? — any reputable contractor will provide these without hesitation.
- Are you BALI accredited or a member of a recognised professional body? — accreditation provides independent verification of standards.
- What insurance do you carry, and does it specifically cover herbicide application? — a general trade policy may not cover pesticide incidents.
- Will you provide a COSHH assessment and risk method statement before starting? — these are legal requirements, not optional extras.
- What written records will I receive after the treatment? — you should receive a full spraying record after every visit.
- What do you recommend for ongoing weed management at this site? — a contractor who only offers one-off treatments without considering the seasonal cycle is not thinking about the outcome for your site.

Frequently Asked Questions
What certifications should a weed spraying contractor in Kent hold?
As a minimum, PA1 certification is required for all commercial herbicide spraying. For any work on hard surfaces, car parks, or near drainage or watercourses, PA6AW certification is also legally required. Always ask to see both certificates before instructing any contractor.
What is the difference between a weed spraying contractor and a general gardener?
A certified weed spraying contractor holds PA1 and PA6AW certification, carries public liability insurance covering herbicide application, produces COSHH assessments and risk method statements before every job, and provides written treatment records after every visit. A general gardener without these qualifications cannot legally carry out commercial herbicide spraying.
How much does commercial weed spraying cost in Kent?
Pricing depends on site size, surface type, weed pressure and frequency. Most commercial sites benefit from a seasonal contract of 3-4 visits per year. A free site survey is the only reliable way to get an accurate price. See our car park pricing guide for typical ranges.
