Water leaks on the customer side of your property can lead to costly water bills, property damage, and potential disruptions to your water supply. Identifying and fixing leaks early is essential for preserving your property’s water system and avoiding costly repairs in the future.
As an approved plumber, we specialise in customer-side leak detection and repairs. We offer professional, reliable services to ensure your plumbing and heating systems remain efficient, safe, and compliant with regulations.
Whether you’re facing a sudden drop in water pressure, unusually high water bills, or visible signs of leaks such as damp spots, our expert team is here to help. We utilise advanced equipment and proven techniques to detect and repair leaks quickly and efficiently, saving you time and money.
The customer side refers to the section of the water supply system that runs from the property boundary to your home, including the pipes inside your property. While water companies are responsible for the water main and the pipes running up to the property boundary, homeowners are responsible for the water supply pipe and internal pipework on their side of the boundary. This includes leaks in underground pipes, internal plumbing, and even issues related to appliances or fixtures.
Leaks on the customer side can occur in a variety of places, including:
Detecting leaks early is crucial to preventing water damage and avoiding high water bills. Common signs that you may have a leak on your property include:
If you notice any of these signs, acting quickly is essential. Our leak detection and repair services can pinpoint the source of the leak and address the issue before it escalates into a more significant and costly problem.
Your water meter is a valuable tool for identifying hidden leaks. Follow these steps to check for leaks:
Finding the exact location of a leak can be challenging, especially when the leak is hidden underground, behind walls, or within concrete floors. Our team of approved plumbers uses state-of-the-art leak detection equipment to accurately locate leaks with minimal disruption to your property.
We utilise a variety of non-destructive leak detection techniques to locate leaks quickly and accurately:
Once the leak is detected, our team of experts provides prompt and effective repair solutions. We are experienced in working with various plumbing systems and materials, ensuring your leak is fixed to the highest standards.
If you have a water meter, remember that it accounts for all water that passes through it, including any water that escapes from leaks in the supply pipe. And your bills will include the cost of the water wasted through the leak and the water you’ve used. Thames Water recognises that hidden leaks can often go unnoticed:
If Thames Water approves your claim, they will credit your account with any water cost accumulated on your bill. If you qualify, we can provide you with a leak allowance for leaks on any internal pipework or water fittings once. For supply pipe leaks, you can claim as many times as needed.To apply for an allowance, please visit: thameswater.co.uk/leakallowance.
As a homeowner, you're responsible for the water supply pipe that runs from the boundary of your property into your home. This includes all internal pipes, appliances, and fittings. Thames Water is responsible for the communication pipe that links your supply pipe to their water mains.
Signs of a leak on your property may include damp areas in your yard, reduced pressure at your cold kitchen tap, or an unusually high water bill. You can also conduct a meter test by turning off your internal stop tap and observing the meter for any movement, indicating a potential leak.
Once a leak on your supply pipe is confirmed, consider the following steps:
Thames Water may offer assistance for supply pipe leaks, depending on your specific situation and with homeowner permission. They typically use trenchless methods, like impact moling, to minimise property disruption.
Thames Water expects leaks to be repaired within four weeks to prevent water wastage and property damage. If not fixed within this period, they may issue a Section 75 legal notice under the Water Industry Act 1991. If repairs are delayed, Thames Water may undertake the repair themselves and potentially recover costs from you.
If you have a water meter and the leak has increased your water usage, you may be eligible for a leak allowance to cover the extra cost. To qualify, you must repair the leak within four weeks of detection, claim the allowance within three months of the repair, and ensure the leak wasn’t due to negligence. This allowance covers the water lost, effectively reducing your bill.
To apply, visit the Thames Water website at thameswater.co.uk/leakallowance and submit your application. You’ll need to provide details of the repair and, if possible, an approved plumber’s certificate or proof of repair to support your claim.
If the leak is on a shared supply pipe, all property owners sharing the pipe are jointly responsible for arranging repairs. Thames Water is responsible for the pipes up to your property boundary, so internal repairs are your responsibility. Coordinating with your neighbours and getting collective permission for the work is essential.
At London & SurreyWater Services, we often use trenchless technology, like impact moling, to replace or repair the pipe with minimal digging. This method involves using a pneumatically driven tool to form tunnels below ground to install new sections of pipework to bypass the leak position, reducing the need for excavation and preserving landscaping or driveways.
If you suspect a leak in your internal plumbing, such as behind walls or under floors, consult a qualified leak detection company for leak detection and repair. Remember, Thames Water is only responsible for the pipes up to your property boundary, so internal repairs are your responsibility. Fixing internal leaks quickly is essential to avoid property damage and high water bills.
At London & Surrey Water Services, we are dedicated to providing an expert leak detection and repair service. Our team of professionals uses advanced, non-invasive techniques to identify and fix leaks efficiently, ensuring minimal disruption to your property.
