A dripping pipe rarely stays a dripping pipe for long. Left unchecked, even a small leak can swell your water bill, damage flooring and walls, and eventually turn into a full-blown emergency. That’s why knowing how to report a water leak quickly — and who to call when you spot one — is one of the most useful things any homeowner, tenant, or driver can learn.
Whether you’ve noticed water pooling under the kitchen sink, a puddle forming on the pavement, or a burst main flooding the street outside your home, this guide walks you through exactly what to do next.
Why It’s Important to Report a Water Leak Quickly
Water leaks rarely announce themselves loudly. They start as a faint hiss behind a wall, a damp patch on the ceiling, or a slightly soft spot in the garden. But the longer a leak goes unreported, the more expensive and disruptive it becomes.
Reporting a leak promptly helps you:
- Prevent structural damage to floors, walls, and foundations
- Avoid inflated water bills caused by continuous water loss
- Reduce the risk of mould and damp, which can affect health
- Stop small problems becoming emergencies, like burst pipes or flooding
- Protect your neighbours’ properties, especially in shared buildings
If you’re already seeing signs of water damage, it’s worth having a professional carry out leak detection and repair to pinpoint the source before it worsens.
How to Report a Water Leak in Your Home
If the leak is inside your property — under a sink, behind an appliance, or around a toilet — here’s how to handle it:
- Turn off the water supply at the stopcock if the leak is significant.
- Identify the source where possible (a pipe joint, tap, or appliance connection).
- Take photos of the affected area for your records or insurance.
- Contact a licensed plumber to inspect and repair the leak safely.
Many leaks — particularly slow ones — go unnoticed for weeks. If your water bills have crept up unexpectedly or you’ve noticed damp patches with no obvious cause, it’s a strong sign you need to report a leak to a professional rather than wait it out. Our team regularly deals with everything from minor drips to major burst pipe repairs, so no job is too small or too urgent.
Report a Water Leak in My Area: Who to Contact
If you’re searching for how to report a water leak in my area, the right contact depends on where the leak is:
- Inside your home or on your property → Call a local plumbing company for emergency repairs.
- On a shared pipe or communal system (flats, housing estates) → Contact your building management or landlord first, then a plumber if needed.
- On the street, pavement, or public land → Report it to your regional water supplier, as this is usually classed as a burst water main.
Searching “leak near me” is often the fastest way to find local emergency plumbers who can attend quickly, assess the damage, and carry out repairs the same day.

How to Report a Burst Water Main
A burst water main is a different situation entirely from a household leak. These typically appear as:
- Water bubbling up through the road surface or pavement
- A sudden, strong flow of water with no obvious source
- Sinkholes or soft, sunken sections of road
- Discoloured or muddy water flooding an area rapidly
Because burst mains involve the public water network rather than private plumbing, you’ll need to report a burst water main directly to your local water company rather than a private plumber. Most UK water suppliers (such as Thames Water, Affinity Water, or your regional provider) have 24/7 hotlines and online reporting tools specifically for this. They’re responsible for the pipework up to your property boundary, so any burst affecting the road or shared supply lines falls under their remit.
How to Report a Water Leak on the Road
If you spot water leak on road surfaces — for example, a steady trickle along the gutter, standing water with no rain to explain it, or a wet patch that never dries — this is very likely a sign of an underground leak in the water network.
To report a water leak on the road:
- Note the exact location (street name, nearest number, or landmark).
- Take a photo if it’s safe to do so.
- Contact your water supplier’s leak-reporting line or online form.
- If the leak is causing immediate danger (e.g., flooding a road or affecting traffic), also notify your local council.
Road leaks can be deceptively slow-moving but costly in wasted water, so even a small trickle is worth flagging.
How to Report a Water Leak in the Street Online
Most major UK water companies now offer a simple way to report a water leak in the street online, without needing to call. Typically, the process involves:
- Visiting your water supplier’s website and locating their “report a leak” page.
- Entering the location using a postcode, map pin, or street address.
- Describing what you’ve observed (size, flow, location).
- Submitting the report — you’ll usually receive a reference number and estimated response time.
This method is especially useful outside office hours, when phone lines may be busier, and it creates a clear paper trail if follow-up is needed.
When to Call an Emergency Plumber Instead
Not every leak needs a water company — many need a plumber, and fast. If the issue is inside your property, affecting your own pipework, fittings, or appliances, an emergency plumbing callout is the right move. Signs you need urgent help include:
- Water actively flooding a room
- A burst pipe inside walls or under floors
- Loss of water pressure alongside visible leaking
- Leaks near electrical fittings (a safety hazard)
Our team offers fast response across London, with experienced engineers ready to diagnose and fix the problem the same day. If pressure issues are part of the picture, it may also be worth checking our water pressure problem guide for related troubleshooting.
Preventing Future Water Leaks
Once a leak is resolved, a little prevention goes a long way:
- Have pipework inspected annually, especially in older properties
- Insulate exposed pipes ahead of winter to prevent freezing and bursting
- Fix small drips immediately rather than waiting
- Consider a planned preventive maintenance plan if you manage a commercial property or larger building
Routine checks catch problems while they’re still cheap and easy to fix, rather than after they’ve caused real damage.
FAQs
How do I report a water leak near me?
Search online for local emergency plumbers or your regional water supplier’s leak-reporting page. For leaks inside your property, a plumber is the right call; for leaks on public roads or shared mains, contact your water company directly.
Is there a difference between reporting a leak and reporting a burst water main?
Yes. A household leak is usually a private plumbing issue best handled by a plumber. A burst water main involves the public supply network and should be reported to your water company, since they own and maintain that infrastructure.
Do I have to pay to report a water leak?
Reporting a leak to your water supplier is free. If the leak is on your own property and requires a plumber, you’ll pay for the repair itself, though many companies offer a free initial assessment.
What should I do if I see water leaking on the road?
Note the location, take a photo if safe, and report it to your local water supplier’s leak line or online form. If it’s causing a hazard, also contact your local council.
Can I report a water leak in the street online?
Yes, most UK water suppliers have online forms where you can submit the leak location and description, along with a reference number for tracking.
How quickly will an emergency plumber respond to a leak?
Response times vary by provider, but reputable emergency plumbing services typically aim to attend within a few hours, especially for active flooding or burst pipes.
What happens if I don’t report a leak?
Unreported leaks tend to worsen over time, leading to higher water bills, structural damage, mould growth, and potentially far more expensive repairs down the line.
