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.Â

We engaged with Alan to have our water main and internal piping replaced as they were made of lead. Alan came and gave us a comprehensive explanation of the work required and how to engage with Thames Water under their lead replacement scheme. He was the only person we could find that was up to handling both external moling and the internal works. Alan spent 2 days in our home completing the work, was polite and extremely unfazed by complications. He managed to reroute the piping under our tiled floor without having to break into it at all. The other reviews are very accurate and I couldn't recommend him highly enough!
After six months of wrangling with Thames Water, an insurance company, a motley collection of leak inspectors, pipe contractors and two plumbers, we still had a mains water pipe unrepaired and leaking under our drive. Alan came over, diagnosed a solution in minutes, and returned within a week to singlehandedly repair everything with care and without fuss. He really knows his stuff, and is wholly professional in his work. If only we had called him six months earlier. His company thoroughly deserves the five stars.
I had a leak and my water had shut down completely but the leak was not visible. The insurance company told me I needed to get someone in to do track and trace which I did and they totally scammed me. I had no water for 3 days and then I found Alan and he came round promptly, located the leak without all this track and trace equipment, took the floorboards up and fixed the leak, water back working — all in under an hour and at such a very reasonable cost. I cannot rate him enough and would highly recommend him.
Alan (aka London and Surrey Water Services Ltd) turned up and made two access points at the water meter and garage. Then with the precision of NASA he used a tunnelling mole and came up bang centre of his target. This was amazing to watch — a distance of over 20 feet with minimal disruption. My new water supply was in, effectively, efficiently and at very reasonable cost since he didn't have to dig up all my drive to find the leak at great expense. No hesitation in recommending Alan.

Alan did a fantastic job for us investigating and resolving poor water flow issues to our flat. Other Thames Water approved plumbers were proposing major replumbing with quotes as high as £20k and even charged to quote. Alan proposed replacing the pipework from the road with wider gauge pipe as the first step and the problem was solved for barely a twentieth of that cost. He's clearly an expert at solving domestic plumbing problems and stood out from every other firm we spoke to. Can't recommend enough!
I contacted Alan following a letter from Thames Water advising of a water leak at my property. Having popped over to determine the likely cause, Alan sent through an itemised quote and patiently answered my additional questions. He and Pierce carried out the work in a thoroughly professional and minimally intrusive manner by moling a new pipe under my driveway and installing a new internal stop valve. London and Surrey Water Services combine subject matter expertise, assuredness, clarity, reliability, responsiveness and honesty. They made a stressful incident so much easier to deal with.
We contacted Alan to detect a leak because of which our water bills had been through the roof for several months. He was extremely professional, answered my questions patiently, detected the leak with no interruption to our day and above all, coordinated with Thames Water to repair the leak. He was very prompt in replying to any messages or questions I sent him and voluntarily sent me all the information I needed to claim a leak allowance from Thames Water. One of the best customer service experiences I have had in a long time!
After a disappointing experience with another plumber whose work failed to meet the water company standards, we contacted Alan and we're so glad we did! Alan came to the rescue, immediately identified the substandard installation, and redid the entire lead pipe replacement to a professional standard. He was highly efficient, knowledgeable, and genuinely trustworthy. He explained everything clearly and carried out the work with great care and precision. The difference in quality was obvious. Thanks to Alan, everything passed inspection with no issues, and we finally have peace of mind. Highly recommended!
I first found Alan McBride of London and Surrey Water Services in 2016 after I had no water for weeks and Thames refused to do anything about it. He was unbelievable in his knowledge, his support, going over and above by advocating for me with Thames and getting the problem fixed. 7 years later I called on Alan again and it is inspiring to watch how thorough he is and how his mind works. He worked it out and the fix was simple. He really is quite a plumbing and water specialist genius!
A calm, pleasant and reassuring presence, Alan turned up early for his appointment and made replacing a leaking supply pipe under our Victorian house in West London seem like a simple task, causing the minimum of disruption. He is highly knowledgeable, efficient and professional, and even reduced his already-reasonable invoice because part of his quotation did not need to be done. Honest, conscientious and down-to-earth, Alan is a pleasure to deal with.
I found Alan's details on the Thames Water WaterSafe Approved Plumbers list and chose to contact him because of the amazing reviews he has received on Google. Alan was able to successfully install an internal water stopcock into a Victorian terrace house with very complex plumbing. Alan was very easy to deal with, very hard-working and explained exactly what he was doing. Alan's prices are also very reasonable. I will definitely contact Alan and London and Surrey Water Services for any future plumbing requirements I have. Very highly recommend.
Alan has done a fantastic job replacing our lead mains pipe following an internal water leak. He is helpful, professional and clear providing sensible advice including utilising his great experience and knowledge of working with Thames Water. He is quick to respond to any queries and he works diligently and neatly. To do the final connection once Thames Water were ready, Alan came back to complete the job with no fuss. Really strongly recommend Alan and really pleased we chose him.
Alan was superb from start to finish. From arriving to prepare a quote, doing the work, tidying up and making good and coming back to finish once Thames Water had completed their part of the lead pipe replacement. He helped with the various administration parts of the lead pipe replacement scheme by Thames Water which saved a lot of confusion, providing advice and explanation every step of the way. I would not hesitate to recommend Alan for any other similar work.
Called Alan to investigate a leak at the end of the driveway. He replaced the supply pipe into the house without disturbing the driveway which was a bonus. He was very professional, knowledgeable, personable and helped us submit for the lead pipe replacement scheme with the water company. Regularly checked in with us as the works between himself and water company were coordinated. Highly recommend Alan.

Clear answers to common questions about trenchless moling, water pipe replacement, and working in London properties
Impact moling is a trenchless installation method for replacing or installing water supply pipes without extensive excavation. This technique involves boring a small tunnel underground to insert the new pipe, minimising surface disruption
Traditional trenching methods require digging large trenches, which can damage landscaping, driveways, and existing structures. In contrast, impact moling creates minimal disturbance by boring a small tunnel, resulting in a quicker, less invasive installation process.
You may need water supply pipe replacement if you experience low water pressure, frequent leaks, or require lead pipe replacement. Installing a new pipe can improve water quality, increase flow rates, reduce repair costs, and enhance system efficiency.
One of the key benefits of impact moling is the minimal disruption it causes. Only small access points are required, meaning far less impact on your landscaping, driveway, and surrounding areas
