Report an Environmental Incident (GOV.UK)

When a spill, leak, or pollution event happens, the fastest way to reduce environmental harm and enforcement risk is to act immediately and report it correctly. This page explains when and how to report an environmental incident using the official GOV.UK guidance, and how to connect that reporting step to practical spill control measures on site.

Question: What counts as an environmental incident?

An environmental incident is any unplanned event that could cause pollution or harm to the environment. In industrial and commercial settings, this commonly includes:

Oil and fuel spills from tanks, bowsers, generators, or plant refuelling points
Chemical leaks (including acids, alkalis, detergents, solvents, and process fluids)
Contaminated water entering surface water drains, ditches, streams, or soakaways
Sewage or effluent escapes from IBCs, pipework, pump stations, or interceptors
Any discharge that could impact rivers, lakes, groundwater, land, or protected habitats

If you are unsure, treat it as potentially reportable and follow the official guidance.

Solution: Use the official GOV.UK reporting route

Follow GOV.UK guidance to report an environmental incident and contact the correct authority. Start here:

GOV.UK - Report an environmental incident (citation: GOV.UK)

This is the authoritative source for who to contact and what information to provide. Keep it bookmarked in your spill response plan and include it in site inductions and emergency folders.

Question: When should I report a spill or pollution event?

Report as soon as possible when there is a risk that pollution has occurred or could occur, especially if:

Liquid has entered (or is likely to enter) a surface water drain, watercourse, or soakaway
The spill is beyond your site boundary or could become so (runoff, windblown absorbents, overland flow)
There is a strong odour, visible sheen, foaming, fish distress, or discolouration of water
You cannot fully contain, recover, and clean up using your on-site spill kit and equipment
There is a risk to groundwater (e.g., unbunded storage, cracked hardstanding, permeable ground)

Even if you have contained the spill, reporting may still be appropriate if pollution reached drainage, land, or water.

Solution: Report, then record, then review controls

A robust incident response is not just about making the call. It is about demonstrating control and prevention. A practical flow is:

Make safe: stop the source if safe to do so (close valves, isolate pumps, upright containers).
Contain: deploy drain covers, spill berms, absorbent socks, and temporary bunding to prevent migration.
Notify: report via GOV.UK route and follow any instructions given.
Recover and clean: use suitable absorbents and arrange waste disposal as required.
Document: record time, location, weather, substance, estimated quantity, actions taken, photos, and who you contacted.
Prevent recurrence: review bunding, storage practices, and spill kit suitability.

Question: What information will I need when I report?

Having the right details ready helps the regulator respond quickly and supports your compliance evidence. Prepare:

Site details: address, nearest postcode, and access notes
Location on site: yard, loading bay, tank farm, plant room, or drain reference
Substance: fuel, hydraulic oil, coolant, chemical name, or Safety Data Sheet reference
Approximate quantity: litres/kg and whether release is ongoing
Pathway: has it reached a drain, watercourse, or soil?
Actions taken: shut-off, containment, drain protection, absorbents used
Impacts observed: sheen, odour, staining, foam, wildlife impacts

Tip: Store a printed spill response checklist in your spill kit station and include the GOV.UK link in your emergency response procedure.

Question: How does incident reporting link to spill control and compliance?

Reporting is one part of an overall pollution prevention duty. Operationally, effective spill management should show you have:

Appropriate spill kits located near risk points (refuelling, IBC storage, chemical dosing)
Drain protection available for rapid deployment (covers, blockers, mats)
Bunding and containment for tanks and chemical storage (bunded pallets, drip trays, bunded areas)
Training and drills so staff can stop, contain, and report without delay
Maintenance on valves, hoses, couplings, and overfill protection to reduce incident likelihood

By combining reporting with competent on-site spill response, you reduce environmental harm and support good governance, audit readiness, and environmental management objectives.

Site examples: When this GOV.UK guidance is most relevant

Warehouses and yards: forklift battery acid, diesel spills, or IBC leaks near yard drains
Manufacturing: coolant and process chemical losses from pipework or bunded areas
Facilities management: generator day tank leaks, plant room spills, or interceptor issues
Construction and civil works: refuelling incidents, hydraulic hose bursts, or silt-laden runoff
Water features and landscaped sites: pump and dosing leaks, or accidental chemical entry to water systems that could overflow to drains (context: Serpro water features)

Solution: Strengthen prevention around high-risk points

To reduce the likelihood of a reportable incident, focus on prevention controls in the same areas where spills typically start or spread:

Install drip trays under valves, hose reels, and coupling points.
Use bunded storage for oils and chemicals and keep bunds clear of rainwater and debris.
Position spill kits and drain covers at loading bays, tank farms, and near surface water drains.
Review your spill response plan after any incident and update training accordingly.
