Thames Water leak reporting: official routes and private repairs
To report a Thames Water leak, use Thames Water’s official leak-reporting service linked here. A street or public-network report goes to the water company; a private plumbing booking is a separate service. Loyal Plumbers is an independent plumbing company, not Thames Water, and this page does not show live incidents or dispatch utility repair teams.

Discuss your plumbing workUse the official reporting route first
Open Thames Water’s leak guidance and follow its reporting link for a suspected leak on its network. If you are unsure whether Thames Water supplies the clean water at the location, check the supplier before submitting the report. In parts of London, the company dealing with wastewater is different from the company supplying tap water.
Provide the location and what you can actually see, rather than selecting a technical cause you cannot confirm. A stream across a pavement, water emerging beside a cover and a wet patch in a garden are different observations. Where the official service gives an incident reference or shows an existing report, keep that information. A private contractor cannot update the water company’s incident system or promise when its crew will attend.
Describe the location from a safe position
Use a nearby address, road name, junction or recognisable landmark. Explain which side of the road is affected and whether water is reaching an entrance or creating a hazard. An existing photograph can help if it was taken safely. Do not step into traffic, enter floodwater or lift a public cover to obtain a better view.
Tell the reporting service if the situation changes materially, such as water beginning to enter a building or a surface becoming unstable. Keep people away from an obvious hazard. The water company needs accurate information to assess its response; it does not need a member of the public to expose the pipe. If there is an immediate threat to life, use the appropriate emergency service rather than relying solely on a routine online report.
Do not decide ownership from the wet patch alone
Water can travel before reaching the surface. A leak appearing on private land may need the pipe arrangement checked, while a wet public area does not by itself identify the failed asset. Thames Water’s responsibility guidance distinguishes its network from private supply pipework, but the actual route and connections matter at a particular property.
Avoid authorising excavation on an assumption about where the water must originate. Ask what evidence identifies the pipe and who is responsible for it. If a supplier visit concludes that the problem is private, request the useful findings and reference. Those can support a focused private investigation. A location marked on a map is a starting point for coordination, not permission for a private plumber to work on supplier apparatus.
Separate a network incident from damage inside your home
A network leak and a household plumbing problem can need different responses at the same time. Report the suspected network event to the supplier. If water is entering the home or private pipework is actively leaking, explain that separately when seeking plumbing help. Tell each organisation what the other has confirmed, without assuming one appointment covers both jobs.
Use only known, safely accessible normal isolation controls where appropriate for a private leak. Do not operate an unfamiliar street valve, enter a flooded chamber or approach water near electrical equipment. A plumber can assess the private installation and necessary access within the agreed scope. The water company remains the contact for its network response, and other emergency or building-management help may be required where the situation presents additional hazards.
Keep the report reference and follow the supplier’s updates
Record when the issue was reported, the location used and the reference received. If several neighbours are affected, a shared factual summary can reduce conflicting descriptions, but each household should follow the supplier’s advice for its own circumstances. Do not treat a social-media estimate or another street’s incident as a confirmed restoration time for your address.
This article cannot tell you whether a particular leak has been repaired today. Use the supplier’s current reporting and incident information for that question. If a report appears closed while the same visible problem remains, contact the supplier with the reference and current observation. Distinguish continuing water, residual surface wetness and a newly changed condition rather than assuming they all prove the same fault is still active.
Know when a private plumbing enquiry is useful
Contact a private plumber when the evidence points to your supply pipe or internal installation, or when private damage needs assessment alongside the supplier response. Give Loyal Plumbers the postcode, symptoms, supplier findings and any access limitations. Say whether water is still escaping and whether the affected installation has been safely isolated. Documents or photographs can be shared by arrangement after contact.
Ask the proposed work to distinguish investigation, private pipe repair, access and reinstatement. If responsibility is not yet established, say so; the enquiry should not be presented as permission to repair public assets. Our role is to discuss the plumbing work we can assess and carry out at your property. Reporting a Thames Water leak through the official route remains a separate step and does not book a visit with Loyal Plumbers.
Common questions
- Can Loyal Plumbers report a live Thames Water repair time?
- No. Current network status and repair updates must come from Thames Water’s official service. This page explains reporting and private plumbing boundaries, not live incident progress.
- Should I lift the street cover to photograph the leak?
- No. Describe the location and visible conditions from a safe position. Do not enter chambers, traffic or floodwater or interfere with supplier equipment.
- Can a private plumber fix a pipe owned by Thames Water?
- A private booking does not authorise work on the supplier’s assets. Confirm the pipe and responsibility first; private plumbing work and network repairs follow different arrangements.
