Environmental permits alongside planning permission
A permit regulates how an activity operates. Planning decides whether the land use is acceptable. Neither authorises the other, and planning should not duplicate what the permit controls.
An environmental permit and planning permission answer different questions, and a business that treats them as one process usually discovers the mistake at the worst point. Planning decides whether the development and the use of the land are acceptable in that location. A permit, granted under the Environmental Permitting Regulations 2016, decides whether the activity can be operated within limits on emissions, using appropriate techniques, without unacceptable risk to the environment or to health.
Neither substitutes for the other. A waste transfer operation with a permit and no planning permission is unlawful development. The same operation with permission and no permit is committing an offence under the permitting regime. Both statements are routinely surprising to operators who have been through one process only.
Which activities need a permit
The Regulations cover regulated facilities, and the families that come up most in planning work:
- installations carrying out listed activities, from combustion plant and chemical processes to intensive pig and poultry rearing
- waste operations, including transfer stations, treatment facilities, landfill and composting
- mobile plant, such as a mobile crusher or a mobile screening plant
- water discharge activities, including discharges of trade or sewage effluent to a watercourse
- groundwater activities, including discharges to ground
- flood risk activities, covering works in, under, over or near a main river or a flood defence
- radioactive substances activities
Smaller operations may be covered by an exemption, registered rather than permitted, with tight limits on tonnage, storage and the type of waste handled. Exemptions are useful and easy to outgrow, and a site operating beyond its exemption is unpermitted rather than lightly regulated.
Which regulator applies depends on classification. The Environment Agency handles most installations and waste operations. Local authorities handle certain smaller combustion and process activities under local air pollution control, which is why a dry cleaner or a small foundry may be dealing with the council on both consents at once.
Why both consents are needed
The regimes have different statutory purposes. Planning control derives from the Town and Country Planning Act 1990 and is concerned with the development and use of land, weighed against the development plan and other material considerations. Permitting derives from the Environmental Permitting Regulations 2016 and is concerned with the operation of the facility: emission limits, monitoring, techniques, accident prevention and site condition on surrender.
So the questions are distinct. Planning asks whether an industrial use belongs on the edge of a residential area. The permit asks, given that it is there, what may come out of the stack and how it is measured.
What each regime controls
| Matter | Planning | Permit |
|---|---|---|
| Location and land use | Yes | No |
| Built form, height, appearance | Yes | Only where it affects emissions, such as stack height |
| Emission limits and monitoring | No | Yes |
| Choice of abatement technique | No | Yes |
| Hours of operation | Yes | Sometimes, where linked to emissions |
| Vehicle movements and access | Yes | No |
| Site restoration after use | Sometimes, by condition | Yes, on surrender |
| Odour and noise from the process | Only where not controlled by the permit | Yes |
The overlap rows are where disputes happen. A permit may control odour from an anaerobic digestion plant through a management plan, while the council is being pressed by neighbours to impose its own odour condition. National guidance is clear that the planning system should assume the pollution control regime will operate effectively, which means the council's proper focus is on whether the use is acceptable in that location rather than on rewriting the permit.
How the two processes interact in time
Permit determination takes months, longer where the application is complex or where a public consultation draws objections. Planning determination is eight weeks for a minor scheme and thirteen for a major one, extensions aside.
A sensible sequence for a new facility:
- Pre-application discussions with both the planning authority and the permitting regulator, separately and early.
- Scope the technical work once, so the same noise, odour and air quality assessments serve both applications where the methodology allows.
- Submit the planning application, with the permit application either in parallel or shortly after.
- Keep the two sets of drawings aligned, because a stack height, bund capacity or drainage change required for the permit is a planning change too.
- Resolve conditions at the end, checking that planning conditions do not conflict with permit requirements.
Illustrative example: a small waste transfer station on an industrial estate. The planning application deals with the building, the yard layout, vehicle access and hours. The permit deals with waste types and tonnages, storage times, dust and odour management, and surface water. The air quality and noise assessments prepared for planning also support the permit, with the noise assessment extended to cover night-time deliveries because the permit will control them. Illustrative only.
Matters planning should not duplicate
Duplication wastes everyone's time and produces unenforceable conditions. A planning condition requiring compliance with emission limits already in a permit adds nothing and creates two regulators for one obligation. A condition requiring a permit to be obtained is unnecessary, because the permitting regime operates independently.
Where the council has a legitimate concern about a matter the permit covers, the better route is a condition dealing with the land use consequence rather than the emission. Hours of operation, the location of the odour source within the site, the height and position of a stack, screening and the routing of vehicles are planning matters that bear on emissions without duplicating their control.
Conditions and their overlap
Read the two sets of conditions together before accepting either. Common conflicts:
- a planning condition restricting hours that prevents the operator meeting a permit requirement for continuous monitoring or for prompt treatment of putrescible waste
- a permit requiring a bund or an impermeable surface that the approved landscape scheme does not allow room for
- a planning condition limiting vehicle numbers set below the throughput the permit allows
- a planning condition requiring an odour management plan in different terms from the permit's plan
Where a conflict appears, raise it before the decision is issued. Varying a permit and varying a permission are both possible and neither is quick.
The supporting evidence for the planning side is ordinary technical work: an Odour Assessment where a process has odour potential, a Noise Impact Assessment covering plant and vehicle noise at the nearest receptors, an Air Quality Assessment where emissions or traffic affect an air quality management area, and a Waste Management Strategy where waste handling is part of the proposal. The full range sits across all 66 report types.
Sequencing the applications
If you take one thing from this: talk to the permitting regulator before the drawings are fixed. The permit will drive stack heights, bund volumes, hardstanding extents, drainage separation and storage layouts, and each of those appears on the planning drawings. Applicants who discover the permit requirements after permission end up with a non-material amendment at best and a fresh application at worst.

Frequently asked questions
Does an environmental permit remove the need for planning permission?
No. The two regimes are independent. A permit authorises an activity to operate within stated limits and does not authorise development, while planning permission authorises development and does not authorise the operation. A site can hold one and be unlawful for want of the other.
Which activities need a permit?
Regulated facilities under the Environmental Permitting Regulations 2016, which include industrial installations, waste operations and waste mobile plant, water discharge and groundwater activities, radioactive substances activities and flood risk activities. Some low-risk operations are exempt if registered, and the exemption limits are specific.
Who issues the permit?
The Environment Agency for most installations and waste operations, and the local authority for certain smaller combustion and process activities under local air pollution control. Which body applies depends on the classification of the activity, so check before assuming the Agency is the regulator.
Can the council condition matters the permit covers?
It should avoid duplicating pollution control. National guidance expects the planning system to assume the permitting regime will operate effectively and to focus on whether the development is an acceptable use of land. Amenity effects not addressed by the permit, such as hours of operation or vehicle movements, remain planning matters.
Which application should go in first?
Usually planning, or both in parallel. A permit determination can take months and the operator will not want to spend it before the land use is settled, though the permit process can surface design changes, such as stack height or bund capacity, that affect the drawings. Talk to both regulators early.
