There isn't one flood authority in England. Depending on where the water came from, responsibility could sit with your council, your water company, the Environment Agency, or you. Here's how to work out which one, fast — and what you're entitled to if it turns out not to be your fault.

When water is coming into your home, the last thing you want to do is figure out an org chart. But in England, flood risk management is deliberately split across several different bodies, and getting your report to the right one first can be the difference between a same-day response and weeks of being passed around.
According to the House of Commons Library's own briefing on the subject, there is no single body in charge of flooding in England — responsibility is split between the Environment Agency, your council, your water company, and, in some cases, you.
Here's the framework, as set out by Parliament's own research service.
The Environment Agency takes the strategic overview. It manages flood risk from "main rivers" — usually the larger rivers and streams, shown on the EA's own Main River Map — issues flood warnings, and operates flood defences on those rivers.
Your council, acting as your Lead Local Flood Authority (usually a unitary or county council), is responsible for surface water, groundwater, and "ordinary watercourses" — the smaller rivers, brooks and ditches that aren't classified as main rivers. Highway drains are generally also a council responsibility, via the highway authority.
Your water company is responsible for flooding from piped water and sewage, and for surface water drainage from buildings and yards where it connects to their network.
You — if you own land next to a watercourse, you're a "riparian owner," and you're responsible for keeping your stretch of it clear so water can flow through naturally.
The category matters less than what actually happened. Here's how to read the situation in front of you.
This is a sewer flooding incident, and it's your water company's responsibility — report it to their emergency line immediately, whichever company serves you. If wastewater from their sewer has entered your property, you may be automatically entitled to compensation under Ofwat's Guaranteed Standards Scheme: in England, a minimum of £300 (capped at £2,000) for internal flooding, or a minimum of £150 (capped at £1,000) for flooding confined to your garden or land, on top of any repair costs. You must claim within three months of the incident. It won't apply if the cause was a blockage or defect in your own private drains, so keep photos and a timeline either way.
Highway drains are generally the responsibility of the highway authority, which is usually your council. Report blocked or overwhelmed road drains to them directly — in a two-tier area (a county with district councils underneath it), the highway authority and the Lead Local Flood Authority are often the same county council, but not always, so it's worth confirming which department you're reporting to.
Check the EA's Main River Map first. If it's a "main river," the Environment Agency is the risk management authority and operates any flood defences on it. If it's an "ordinary watercourse" — the label for most smaller streams, becks and field ditches — responsibility usually sits with your council as Lead Local Flood Authority, or with an internal drainage board if your area has one.
If a watercourse runs on, through, or under your property, you're likely a riparian owner, with a legal duty to keep your stretch of it clear of blockages so water can flow through naturally. Check your property deeds to confirm. If the blockage is on a neighbouring stretch of the same watercourse, the same duty falls to whoever owns that section — not you.
This is groundwater flooding, and it falls under your council's surface water and groundwater remit as Lead Local Flood Authority. Be realistic about timelines here: groundwater flooding is notoriously difficult and slow to fix, because it often involves the water table itself rather than a single identifiable blockage. Reporting it formally still matters — it's what starts the record that a Section 19 investigation can later draw on.
Report it to every plausible authority, not just your best guess. If you're not sure whether water came from a sewer, a road drain, or a ditch, don't spend the first hour deciding — report to more than one. Getting it to the wrong department first and being redirected costs real time; reporting to two departments costs nothing.
Document as you go. Photos and video with visible timestamps, water depth marked against something fixed, and a written timeline of when it started and what you did. This matters for insurance, for any Guaranteed Standards Scheme claim, and for a future Section 19 investigation if one applies.
Know your Section 19 rights. When your council becomes aware of a flood, it must investigate, to the extent it considers necessary or appropriate, and publish what it finds under Section 19 of the Flood and Water Management Act 2010 — even though, as above, that doesn't compel anyone to fix it. Our FAQs cover this in detail, and our Section 19 Reference Manual goes deeper still.
Use a postcode lookup instead of guessing. Our own flood contacts tool looks up your specific council and MP by postcode in seconds, and links out to Water UK's official supplier lookup so you're contacting the right water company rather than assuming.
That gap — between an authority being formally "responsible" and an authority actually funding or carrying out a fix — is exactly what we've written about at length elsewhere, including how chronically underfunded and understaffed most Lead Local Flood Authorities are relative to the duties Parliament has given them. If you want the fuller picture of why that gap exists, our long read on surface water flooding covers it.
