Internal plumbing systems in London properties are often altered over time through extensions, upgrades, and previous repairs. Properties that began with simple, tank-fed layouts are frequently adapted to serve additional bathrooms, kitchens, and higher-demand appliances
In practice, these changes are commonly made by extending existing pipe runs rather than redesigning the system. Original 15mm feeds are branched repeatedly, hot and cold supplies are rerouted to suit new layouts, and older sections are left in place alongside newer installations. Over time, this creates pipework that is poorly routed, undersized, and unnecessarily complex.
As demand increases, the limitations of the original installation become more apparent. The pipework is then expected to supply multiple outlets simultaneously, support modern appliances, and operate under pressure conditions different from those for which it was originally designed. This often results in systems that cannot meet current usage requirements and begin to show consistent performance issues.
Low flow rates, pressure issues, concealed leaks, shared supply arrangements, and outdated or non-compliant installations are all common. In most cases, the underlying problem lies within the pipework itself rather than in the appliances it serves
At London & Surrey Water Services, we identify faults within internal pipework and correct them at source. Typical works include reconfiguring layouts, replacing restrictive or degraded sections, addressing concealed leaks, upgrading cold water storage arrangements, separating shared supplies, and bringing installations into compliance with current regulations.
We are typically called where flow is inconsistent, pressure collapses under demand, leaks are suspected but not visible, or systems cannot be isolated effectively. In many cases, earlier work has been carried out with little regard for overall system performance, leaving constraints within the pipework.
Where pipework is incorrectly sized, poorly configured, or has deteriorated over time, it will impact overall performance. Works typically involve replacing defective sections, reconfiguring layouts, removing redundant pipework, and carrying out targeted upgrades to improve flow and reliability of the system.
Where pipework is undersized, poorly routed, or has deteriorated over time, performance is compromised. Remedial work removes restrictions, simplifies layouts, eliminates redundant runs, and upgrades critical sections so the system delivers stable flow under reliable control.

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. A truely 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.
