Environmental management used to be treated as an afterthought on construction sites. Today it is a legal, commercial and reputational necessity, and clients increasingly expect supervisors and managers to hold formal environmental training. The Site Environmental Awareness Training Scheme, better known as SEATS, is the CITB Site Safety Plus course designed to meet that need.
This guide explains what the SEATS course covers, the legislation behind it, and how to prepare for the end-of-course assessment so you pass first time.
What Is SEATS and Who Is It For?
SEATS is a one-day course that gives supervisors, managers and anyone with environmental responsibilities a working knowledge of environmental issues on construction sites. It sits alongside the health and safety courses in the Site Safety Plus suite administered by CITB, and it is frequently requested by principal contractors as a condition of appointment for site management roles.
The course is not aimed at environmental specialists. It is aimed at the people who make day-to-day decisions that determine whether a site pollutes a watercourse, breaches its waste duty of care or generates complaints from neighbours. By the end of the day you should understand the main environmental risks on a typical site, the legislation that applies, and the practical controls that keep a project compliant.
The Duty of Care for Waste: The Legal Core of SEATS
If one piece of legislation dominates the SEATS syllabus, it is the Environmental Protection Act 1990, and in particular the section 34 duty of care for waste. The duty applies to everyone who produces, imports, keeps, stores, transports, treats or disposes of controlled waste, which means it applies to virtually every construction business in the country.
What the Duty of Care Requires
The duty of care is often described as a cradle-to-grave responsibility. In practical terms, a waste holder must:
- take all reasonable steps to keep waste safe and prevent its escape;
- transfer waste only to an authorised person, such as a registered waste carrier or a permitted site;
- describe the waste accurately when it is transferred so the next holder can handle it lawfully;
- take reasonable steps to prevent others in the chain from dealing with the waste unlawfully.
The crucial point, and a common assessment question, is that your responsibility does not end when the skip leaves the gate. If your waste is later fly-tipped by a carrier you never checked, you can still be held to account. Checking that carriers are registered and that receiving sites are authorised is not bureaucracy; it is the heart of the duty.
Waste Transfer Documentation
Every transfer of non-hazardous controlled waste must be covered by a waste transfer note describing the waste, identifying the parties and confirming their authorised status. Hazardous wastes, such as asbestos, contaminated soils, oils and many paints and resins, are subject to stricter consignment note procedures and must be segregated from general waste streams. Mixing hazardous and non-hazardous waste to avoid disposal costs is a serious offence, and questions on segregation appear regularly in the assessment.
The Waste Hierarchy
SEATS also expects you to know the waste hierarchy, which ranks waste management options from most to least preferable: prevention first, then preparing for reuse, then recycling, then other recovery such as energy from waste, and finally disposal as the last resort. On site this translates into ordering accurately to avoid over-supply, protecting materials from damage, segregating skips to keep recyclable streams clean, and reusing excavated material where the design allows. The hierarchy is not just good practice; businesses are required to take reasonable measures to apply it when transferring waste.
Preventing Water Pollution
Water pollution incidents are among the most common and most costly environmental failures on construction sites. It is an offence to cause or knowingly permit a polluting discharge to surface waters or groundwater without the appropriate permit, and the environmental regulators take enforcement seriously.
The pollutants that catch sites out are rarely exotic. Silty water pumped from excavations can devastate a watercourse by smothering gravels and gills. Concrete washout water is highly alkaline and toxic to aquatic life. Fuel and oil from refuelling areas, damaged plant or poorly stored drums find their way to drains with remarkable ease. SEATS teaches the practical controls: settle or filter silty water before discharge and get the right permissions in place, use contained washout facilities, store fuels in bunded tanks away from drains and watercourses, keep spill kits available and make sure operatives know how to use them. Understanding the difference between foul and surface water drains, and never assuming a site drain leads anywhere safe, is a recurring theme.
Nuisance: Noise, Dust and Neighbours
Construction sites operate next to homes, schools and businesses, and the Environmental Protection Act 1990 also deals with statutory nuisance, which can include noise, dust and smoke. Local authorities have powers under the Control of Pollution Act 1974 to control construction site noise, including serving notices specifying permitted working hours and methods, and contractors can apply for prior consent for noisy works. For the SEATS assessment, understand the practical controls: planning noisy operations within agreed hours, selecting quieter methods and plant, damping down haul roads and cutting operations to suppress dust, sheeting loads and keeping neighbours informed. Good community relations are treated as part of environmental management, not a separate public relations exercise.
Ecology, Protected Species and Invasive Plants
The natural environment features strongly in the course. The Wildlife and Countryside Act 1981 protects wild birds, their nests and eggs, and gives additional protection to certain species. Works affecting nesting birds, bats, badgers, great crested newts and other protected species can constitute criminal offences, so surveys and ecological advice must come before clearance works, and any unexpected discovery on site should stop work in that area until advice is obtained.
Invasive non-native species are the other side of the coin. Japanese knotweed is the best-known example: it is an offence to plant it or cause it to grow in the wild, and soil contaminated with knotweed rhizome is a controlled waste requiring careful handling and disposal. Recognising the main invasive species and knowing that they change how you manage excavation and soil movement is core SEATS knowledge.
Resource Efficiency and Environmental Management
Beyond compliance, SEATS covers the wider agenda: efficient use of energy, fuel, water and materials, and the environmental management arrangements you will meet on well-run projects, such as site environmental plans, toolbox talks and incident reporting. Regulators, clients and the Health and Safety Executive increasingly expect environmental and safety management to work as one system, and the course reflects that by grounding every topic in day-to-day site decisions.
How to Prepare for the SEATS Assessment
The course ends with a multiple-choice assessment, and the questions reward understanding over memorisation. Rather than trying to memorise act names in isolation, connect each piece of legislation to the site behaviour it drives: the duty of care means checking carriers and paperwork, water protection means controlling silt and washout, nuisance provisions mean managing hours, noise and dust.
Practising with realistic mock test questions before the course is the most efficient way to prepare, because it shows you how environmental knowledge is actually examined and highlights the topics you need to revisit. The study techniques in our complete SMSTS revision guide apply just as well here: short, regular sessions, active recall, and always reading the explanation behind every answer.
Final Thoughts
SEATS is one of the most immediately practical courses in the Site Safety Plus range. Everything in it, from waste transfer notes to spill kits, maps directly onto decisions supervisors make every week. Book the SEATS course, spend a little time beforehand on the duty of care and pollution prevention basics, sharpen up with mock tests, and you will find both the assessment and the real-world responsibilities well within reach.
