Using advanced trenchless moling technology, we install and replace underground water pipes with minimal surface disruption.
We regularly carry out works aligned with Thames Water requirements, including the Lead Pipe Replacement Scheme, customer-side leak detection and repair, and water mains repair. Our specialist team is familiar with the regulatory and access challenges common to London properties and delivers compliant, efficient solutions.
Whether you require a new water pipe installation, lead pipe replacement, or improvements to low water pressure and poor flow rates, our fully qualified engineers provide a professional service designed to minimise disruption to homes, driveways, and business premises. Impact moling allows plastic pipes and underground utilities to be installed accurately without extensive excavation, offering a faster and more cost-effective alternative to traditional trenching methods
Moling services are a specialist trenchless method used for installing water pipes, replacing existing pipework, and carrying out underground utilities work without extensive excavation. Using the latest moling technology, we create precise underground bores that allow new pipes and services to be installed with minimal surface disruption
This trenchless technique is suitable for both residential and commercial clients and is particularly effective in London’s clay-dominant soil conditions, where traditional excavation can be slow and disruptive. Impact moling performs reliably across various ground types, making it an ideal solution for dense, urban and built-up areas where access is restricted and surface disturbance must be kept to a minimum.
Impact Moling is one of the most reliable and least disruptive methods of carrying out water supply pipe replacements employed throughout the water industry today.

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.
