What law requires environmental permits in England and Wales?

The Environmental Permitting (England and Wales) Regulations 2016 (EPR) consolidate permitting for waste operations, water discharges, installations, and mining-waste activities. Larger industrial installations are also driven by the EU Industrial Emissions Directive, which the EPR implements domestically. Scotland and Northern Ireland have parallel regimes.

What is the difference between standard rules and bespoke permits?

A standard rules permit is a pre-set, lower-cost permit for common, lower-risk activities that fit a published rule set — it is quicker and cheaper to obtain. A bespoke permit is tailored to your specific site and is needed when your activity falls outside any standard rule set, is larger, or poses site-specific risks.

When can I use a waste exemption instead of a permit?

Some low-risk waste activities can be registered as exemptions rather than fully permitted, for example storing or treating small quantities of specific waste types. Exemptions still require registration with the regulator and have strict limits on waste type and tonnage; exceed those and you need a permit.

What capacity makes a combustion plant a permitted installation?

Combustion plant with a total rated thermal input of 50 MW or more is a Chapter II installation under the Industrial Emissions Directive and needs a bespoke installation permit. Medium combustion plant between 1 MW and 50 MW falls under the Medium Combustion Plant Directive and needs a permit, while smaller units may be exempt.

Is this a substitute for advice from the regulator?

No. This is an indicative triage tool. The exact permit you need depends on detailed definitions, waste codes, location (such as proximity to protected sites), and emissions. Always confirm with the Environment Agency, SEPA, NRW, or NIEA, and check current charging schemes before applying.

What is the Environmental Permit Requirement Checker (UK/EU)?

Answer questions about activity type (waste management, combustion plant, industrial emissions, water discharge, solvent use) and scale to estimate UK Environmental Permitting Regulations or EU Industrial Emissions Directive obligations, the likely permit tier (exempt, standard rules, or bespoke), and indicative regulator charges.

Many business activities that handle waste, burn fuel, emit to air or water, or use solvents need an environmental permit before they can lawfully operate. This checker applies the main thresholds in the Environmental Permitting Regulations and the Industrial Emissions Directive to tell you the likely permit tier.

How the permit tiers work

UK environmental permitting (in England and Wales, under the Environmental Permitting Regulations 2016) creates three broad tiers of regulatory control:

Exemptions cover low-risk activities that are registered rather than permitted. Registration is typically free or low-cost, quick, and requires no detailed assessment — but the activity must fit a published exemption type precisely and stay within strict waste type and quantity limits. Exceed those limits and the exemption no longer applies.

Standard rules permits are pre-designed permits for common, well-understood activities that carry moderate risk. Because the Environment Agency has already assessed the standard risk profile, an application takes weeks rather than months and costs significantly less than a bespoke permit. If your activity matches a published standard rules permit number, this is the route to target.

Bespoke permits are needed when no standard rules permit fits — because the activity is above the capacity threshold, poses site-specific risks, is located near protected habitats, or involves unusual waste types. The application requires a full assessment, public consultation, and the highest fee band.

How the checker works

The tool routes on activity type, then applies the scale threshold for that route:

Waste:        small + listed type -> exemption (register)
              up to standard-rules limit -> standard rules permit
              above -> bespoke permit
Combustion:   <1 MW   -> often exempt
              1–50 MW -> MCPD permit
              >=50 MW -> IED installation (bespoke)
Industrial:   listed Part A(1)/IED activity -> bespoke installation permit
Water:        discharge to ground/surface water -> permit (standard or bespoke)
Solvent:      over the solvent-use threshold -> installation permit

Indicative charge bands rise with the tier: exemptions are free or low-cost, standard-rules permits are a fixed mid-range fee, and bespoke permits carry the highest application and annual subsistence charges.

Key thresholds to know

The 50 MW thermal input threshold is the dividing line between Medium Combustion Plant Directive (MCPD) treatment and the full Industrial Emissions Directive (IED) installation regime. Above 50 MW you need a bespoke installation permit and must meet IED best-available-technique (BAT) requirements — a significantly heavier obligation.

For waste operations, the specific waste codes and European Waste Catalogue (EWC) codes matter as much as tonnage. A site handling listed hazardous waste streams faces tighter thresholds than one handling inert waste, even at the same physical scale.

Notes and example

A site storing 40 tonnes of non-hazardous waste for transfer is typically within standard-rules permit territory rather than a full bespoke permit, keeping costs and timelines down. A 60 MW biomass boiler, by contrast, crosses the 50 MW Industrial Emissions Directive threshold and needs a bespoke installation permit with the highest charge band. Thresholds and charges change, and location near protected habitats can force a bespoke route — always confirm with the Environment Agency, SEPA, Natural Resources Wales, or NIEA before applying.
