As Water Regulations Approved Contractors, our work is founded on a single core responsibility: protecting public health through the safe design, installation, and management of water systems in buildings.
Plumbing is not simply about delivering water. It is about preventing contamination, controlling risk, and ensuring that water remains safe from the point it enters a property through to every outlet within it.
Every project we undertake is approached with this responsibility in mind.
Water safety is a public health issue. Our mission, vision, and values reflect that responsibility in every project we undertake
Protecting public health through safe, compliant water systems.
Our mission is to safeguard drinking water and reduce health risks within buildings by removing hazards at source and delivering fully compliant water systems that protect the people within.
.
Raising standards in water safety within buildings.
Our vision is an environment where drinking water safety is not taken for granted. We believe that better design, correct materials, and regulation-led workmanship are essential to protecting health.
.
Integrity, responsibility, and technical competence
Our values guide every decision we make. We act responsibly where public health is affected, provide clear and honest advice, and deliver every project with technical care and long-term safety in mind.

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.
