If you experience a plumbing emergency, acting quickly and safely is essential to limit damage, protect your property, and reduce risk. The first and most important step in almost all plumbing emergencies is to turn off the water supply as soon as it is safe to do so, preventing further flooding or water loss before professional help arrives:
.
Shut off the water supply using the internal stop valve. If the leak is external but within your property boundary, locate and close the external stop valve, usually found in the public footpath.

Early detection significantly reduces repair costs and prevents structural damage by stopping water escape before it spreads through floors, walls, and foundations. Identifying a leak at an early stage limits secondary damage such as rot, weakened joists, mould growth, and damage to finishes, which are often far more expensive to repair than the pipe itself.

Turn on the cold tap at your kitchen sink. If water flows strongly here but not elsewhere in the property, the issue is likely within your internal plumbing. You should contact us on 0800 037 1247 for advice or to arrange for one of our approved emergency plumbers to attend.
If no water flows from the kitchen cold tap, check that your internal stop valve is fully open. It is commonly located under the kitchen sink, in a cupboard under the stairs, or beneath floorboards near the front door. Turn the valve anti‑clockwise to ensure it is fully open. You should also check the external stop valve, usually located in the pavement outside your property, to confirm it has not been closed.
Ask nearby neighbours whether they are experiencing the same issue. If their water supply is unaffected, the problem is likely within your property or supply pipe, and you should contact us for assistance. If neighbouring properties are also without water, the issue may relate to the local water network. If you live in a flat, check with your building management company, housing association, or managing agent for any known issues
Your water supply may be affected by a wider network issue already known to the water company. You can check for reported problems or leaks in your area by searching your postcode on the Thames Water website. If you are unsure at any stage, you can contact us at any time for advice or to arrange an emergency visit.
Our emergency response is focused on clearly defined service categories aligned with real-world failures in domestic and commercial water systems
Supply pipe leaks affect the incoming water supply, often underground or beneath floors, causing loss of water supply, reduced water pressure, or unexplained usage. We can locate, isolate, and repair the leak quickly to stabilise the supply.
We help ensure your insurer has the documentation needed to approve your claim and prevent delays
Internal plumbing leaks can develop within walls, ceilings, or floors and often go unnoticed until damage occurs. Using professional leak detection methods, our engineers identify the source and carry out targeted repairs to minimise water damage and water loss.
Early intervention with internal plumbing leaks helps limit structural damage and control repair costs.
A drop in water pressure or complete of loss of supply is a critical plumbing emergency. We investigate faults including supply pipe issues, stop tap failures, internal plumbing defects, and network problems, working to restore your supply as quickly as possible
Resolving pressure or supply failures is essential to restore normal use and prevent secondary damage to plumbing systems.
Failures affecting essential plumbing components such as toilets, taps, storage tanks, and hot water cylinders can disrupt normal use. Our emergency plumbers diagnose faults quickly and carry out urgent repairs or replacements to restore safe operation.
Prompt action on plumbing failures keeps facilities operational and helps prevent faults from escalating into more serious issues.
Discoloured water, unusual tastes or odours can indicate a water quality failure. Causes include lead pipes, backflow, contaminant ingress, or non-approved materials. We identify the source and take corrective action to protect occupants and ensure compliance.
Prompt investigation of water quality failures helps safeguard health, maintain compliance, and prevent further contamination.
In some emergencies, repairs require isolation of a section of the public water main. We coordinate directly with Thames Water engineers to carry out controlled emergency shut downs, enabling urgent repairs to customer-owned pipework.
Managed emergency shutdowns to ensure repairs are completed efficiently, minimising disruption to surrounding properties
Where a property is subject to Section 75 enforcement action, we carry out urgent remedial works to address non-compliant plumbing, supply pipe defects, or water quality risks

We've built a solid reputation through our continually growing customer base as the most trusted team of Approved Plumbers and Moling Contractors in London.
I would highly recommend Alan. I wish we had found him earlier because it would have saved us both time and money. We had a water leak at our house which could not be located. I contacted other “experts” in underground water problems before finding Alan, none of them could offer a convincing solution. Alan is an expert in this area and articulated very clearly the alternative solutions and the pros and cons of each. Alan is very professional, hard working and tidy - you would not be able to tell that concrete and flagstones were removed to do the work. Excellent job.
We had a severe water leak that was flooding the basement of our house. Alan and Grant dealt with this emergency straight away. The organisation for our job was efficient, and we were kept informed at all points in the process. The repair was complex. It required moling through the basement exterior wall and installing a new connection to our internal supply. Alan carried this difficult task out efficiently and quickly, causing the least disruption possible, and it was a pleasure to deal with both him and Grant. Their price for the work was very reasonable. highly recommend!
Alan went above and beyond when installing my new water mains. He was prompt, professional, communicative, and really helpful, taking time after the job was done to offer advice on getting the best out of the new supply. I am amazed at how quickly he could get the job done and left the house so clean afterwards you would never have known he was there. The fact he is Thames Water approved was also a huge bonus and made the whole process much quicker and easier. I can't recommend him highly enough and would 100% use London & Surrey Water Services again.

Clear answers to common emergency plumbing questions, helping you understand what to do, who is responsible, and when professional assistance is required.
In most cases, the property owner is responsible for the supply pipe running from the property boundary to the internal stop valve. If a leak or defect is traced to this pipe, repairs or replacement must be arranged by the owner.
If the issue appears to affect only your property, it is likely an internal plumbing or supply pipe problem and you should contact London & Surrey Water Services so one of our emergency plumbers can investigate. If neighbouring properties are also affected, the issue may relate to the local water network
