If your business could pollute the air, water or land, there is a good chance it needs an environmental permit. Operating a regulated facility without one is a criminal offence, and the consequences can include unlimited fines, enforcement notices, prosecution and, in serious cases, imprisonment.
The tricky part is that “regulated facility” covers a far wider range of businesses than most people expect. It is not just chemical plants and landfill sites. Dry cleaners, vehicle dismantlers, farms, food manufacturers, concrete producers and even businesses running a standby generator can all fall within scope.
This guide explains which businesses need an environmental permit, who regulates them, and how to work out where you stand.
A note on jurisdiction: this article focuses on England and Wales, where environmental permitting is governed by the Environmental Permitting (England and Wales) Regulations 2016. Scotland, Northern Ireland and the Republic of Ireland each operate their own regimes, detailed in a summary at the end.
What is an environmental permit?
An environmental permit is a legal authorisation to carry out an activity that could harm the environment or human health. It sets out conditions the operator must meet, such as emission limits, monitoring requirements, waste handling rules and pollution-control measures.
Permits are issued to the operator of the facility, meaning the person or business that controls how it runs day to day, not necessarily the landowner.
An environmental permit is not the same as planning permission, an ISO 14001 certificate or a waste carrier registration. Each has a separate legal purpose, and holding one does not remove the need for the others.

Which businesses need an environmental permit?
Under the 2016 Regulations, you need a permit (or must register an exemption) if you operate a “regulated facility”. The main categories are below.
1. Industrial installations (Part A(1), Part A(2) and Part B)
Larger industrial processes are regulated as installations. They are split into three tiers based on environmental risk:
- Part A(1) installations are regulated by the Environment Agency (or Natural Resources Wales). They cover the highest-impact activities such as large chemical manufacturing, refining, metals production, major energy and large-scale waste treatment.
- Part A(2) installations are regulated by the local authority and cover emissions to air, water and land from medium-impact activities such as some glass, ceramics and surface treatment processes.
- Part B installations are also regulated by the local authority, but focus on emissions to air only. Typical examples include petrol stations, dry cleaners, mobile crushing plant, concrete batching, coating and printing processes, wood processing and some food and animal feed manufacture.
2. Waste operations
If you treat, store, recycle, recover or dispose of waste, you will generally need a permit. This includes:
- Landfill sites
- Waste transfer stations
- Metal recycling and vehicle dismantling sites
- Anaerobic digestion and composting facilities
- Waste incineration, gasification and pyrolysis plants
- Hazardous waste treatment sites
Some lower-risk waste activities may qualify for an exemption, which still requires registration with the regulator and compliance with set limits on quantities and types of waste. Many businesses assume they are exempt without checking, which is a common route to enforcement action.
3. Combustion plants and generators
Businesses running boilers, engines, turbines or generators can fall within permitting requirements depending on their thermal input. Medium combustion plants (roughly 1 to 50 megawatts thermal input) and specified generators, including some standby and backup generators, may need a permit or registration. This surprises many hospitals, data centres, manufacturers and large commercial sites.
4. Discharges to water and groundwater
You may need a permit if you discharge anything to surface water or groundwater, including trade effluent that is not going to a public sewer, treated sewage effluent from a private system, or cooling water. Some activities that could affect groundwater, such as injecting substances into the ground, also require authorisation.
5. Flood risk activities
Work in, over, under or near a main river, flood defence or sea defence may need a flood risk activity permit. This is relevant to construction, civil engineering, landscaping and riverside development, not just industrial operators.
6. Radioactive substances
Businesses that keep, use or dispose of radioactive material or radioactive waste may need a permit or registration. This can include some hospitals, laboratories, industrial gauging operations and sites handling naturally occurring radioactive material.
7. Mining waste operations
Operators that manage waste from mineral extraction, such as tailings, overburden and waste rock, fall within the regime.
8. Solvent emissions and other specific activities
Processes using significant volumes of organic solvents (for example in printing, coating or cleaning), as well as some intensive farming operations (large pig and poultry units above set capacity thresholds), also require permits.
Who regulates environmental permits?
The regulator depends on the activity:
| Activity | Regulator (England) |
|---|---|
| Part A(1) installations | Environment Agency |
| Part A(2) and Part B installations | Local authority (environmental health or environmental protection team) |
| Waste operations and mining waste | Environment Agency |
| Water discharges, groundwater activities, flood risk activities | Environment Agency |
In Wales, Natural Resources Wales takes the Environment Agency’s role.
What happens if you operate without a permit?
Operating a regulated facility without a permit, or breaching permit conditions, is an offence. Possible consequences include:
- Enforcement and stop notices requiring you to cease operating
- Unlimited fines in the Crown Court
- Prison sentences for individuals in serious cases
- Prosecution of directors and senior managers where an offence is committed with their consent or neglect
- Clean-up and remediation costs
- Reputational damage and difficulties with insurers, lenders and customers
Regulators also publish enforcement outcomes, so a conviction is rarely a private matter.
How to check if your business needs a permit
- Identify every activity on site. Consider waste handling, combustion plant, solvent use, discharges and any work near watercourses, not just your core process.
- Use the official checker. GOV.UK provides a “check if you need an environmental permit” tool covering permits, exemptions and standard rules.
- Check for standard rules permits. Many common activities can be covered by pre-set standard rules, which are quicker and cheaper than a bespoke permit.
- Speak to the regulator early. The Environment Agency or your local authority can confirm whether an activity needs a permit and which type. Pre-application advice can save months and reduce wasted application documents and assessments.
- Keep records. If you conclude no permit is needed, document your reasoning in case a regulator challenges it.
What about Scotland, Northern Ireland and the Republic of Ireland?
The principles are similar, but the legal framework and regulator differ:
- Scotland: regulated by SEPA under the Pollution Prevention and Control (Scotland) Regulations 2012 and the Environmental Authorisations (Scotland) Regulations 2018.
- Northern Ireland: regulated by the Northern Ireland Environment Agency (NIEA) and district councils, under separate Northern Ireland pollution prevention and control and waste regulations.
- Republic of Ireland: regulated by the Environmental Protection Agency (EPA) and local authorities, through industrial emissions licences, waste licences and waste permits.
If you operate across more than one jurisdiction, you cannot assume a permit in one place covers another.
Frequently asked questions
Do small businesses need an environmental permit? Size does not determine whether you need one. What matters is the activity. A small dry cleaner or a small vehicle dismantler can need a permit just as a large manufacturer can.
Is an exemption the same as not needing a permit? No. An exemption usually has to be registered, and it only applies if you stay within strict conditions.
Can I apply for a permit myself? Yes, the operator can apply directly. For complex sites, many businesses use a consultant to prepare risk assessments, management systems and technical submissions, because errors cause delays and rejections.
How long does a permit take? It varies widely. Standard rules permits can be relatively quick and determined within 6-8 months, while bespoke permits for complex sites can take even longer. Regulators set statutory determination periods, and incomplete applications restart the clock.
Do permits cost money? Yes. There is typically an application charge and an annual subsistence charge, which vary by activity and risk rating. Check the current charging scheme with the relevant regulator.
Need help working out whether you need a permit?
Getting this wrong is expensive, whether that means operating illegally or paying for a permit you did not need. At Ashbrooke Management Consultants, we help businesses identify which legislation applies to business operations and sites. Once identified, we compile all the legislation into a register and include the steps required to be compliant.
