Specialist detection and repair of underground water leaks, bursts and damaged supply pipework for domestic and commercial properties.
Tell us what’s happening and leave your contact details.





An underground water leak is not always obvious. Water can travel through the ground before appearing at the surface, which means the wet area you can see may not be where the pipe has actually failed.
Ardent Utilities specialises in locating and repairing leaks and bursts on underground water supply pipework. We assess the problem first and work to establish where the leak is coming from before determining the right repair.
Some leaks can be traced using specialist listening equipment. Others may require further investigation or excavation to narrow down the affected section of pipe.





Underground leaks can show themselves in different ways. If something has changed with your water supply or around the property, it is worth finding out why.
Water appearing at the surface
Unusually wet ground
Changes in water pressure
A suspected burst
Problems along the supply route
Something doesn't look right
Water appearing at the surface does not necessarily mean the leak is directly underneath it. Water can move through the surrounding ground before becoming visible elsewhere.
Specialist listening equipment can help locate leaks and identify the route of underground water supplies. However, not every leak can be pinpointed using listening equipment alone.
The material, position and condition of the supply pipe can all affect how a leak is located and repaired.
Water can travel through the ground before reaching the surface, so the point where it appears may be some distance from the actual leak.
Leaks from plastic supply pipes can be harder to locate acoustically than leaks from metal pipework, so further investigation may be needed.
Where equipment alone cannot pinpoint the leak, targeted excavation may be needed to narrow down the affected section of underground pipework.
If the location or condition of the existing supply makes a repair impractical, replacing the affected supply pipe may be the more appropriate solution.

Great service. Had a horrible underground leak. Enquired with them. But as they were very busy there was a long wait. I called back asking if they could prioritise us as the leak was so bad the shower wouldn’t work. They came out much quicker, the two lads who came and, I apologies I’ve forgotten their names, just got on with. No mess when they had finished, they were happy to explain when I asked what they were doing. Can’t recommend them highly enough. Thanks again Jayne Ste and the team.Posted on Google![]()

This is an amazing company! I’ve been thinking all day how to word my review and can only come up with the old saying that I’m gobsmacked! I had lead pipe replaced by Ardent, a job I believed would be a nightmare. The survey was carried out by two lads who knew their stuff and assured me the job would be done with minimum disruption. But you know what more than anything they were as my son would say ‘top lads’ highly respectful and reassuring. I was told the lads would be at my house by 8.30 on Sunday and they were there on the dot, started work right away and worked until the job was done. When we looked out to see the finished job there was no sign of any disruption, not a speck of soil/ dust/gravel etc. if I hadn’t seen the photos of each stage of the work I wouldn’t have known anything had been done. And you know what these two lads were as good, professional and respectful as the surveyors. The ethos in this company flows through every employee and that is to provide exceptional customer service. The work was done yesterday and by 10 this morning the girls in the office have emailed to me and UU all the documents needed to validate the work. Apologies for long review, if this was an Oscar winners speech I’d have been pushed off the stage but I really want to emphasise how brilliant this company is, my husband and I are like two old cranks excited about our new water pipe. Thanks for everything and the very best of luckPosted on Google![]()

⭐⭐⭐⭐⭐ A huge thank you to Mark, Steve, and the whole team for an absolutely outstanding job installing our new underground water pipes. From the first day to the last, they were professional, friendly, punctual, and kept us informed every step of the way. The workmanship was first class, and they left everything spotless when they finished. You genuinely wouldn’t know they’d been there—everything was put back exactly as it was. It’s rare to find a company that takes so much pride in their work, and it really shows. The attention to detail and the care they took throughout the entire job were second to none. I honestly can’t recommend them highly enough. A fantastic team delivering exceptional service from start to finish. 110%—thank you all for a brilliant job!Posted on Google![]()

Great company and great work. They team at the office were great in dealing with my husbands OCD questions, and the guys who arrived on time, were very polite, got the job done well, avoiding all the underground obstacles in the way of our new water pipe. They tidied up well and you'd struggle to see they'd been, other than the sparkly new pipe and tap in our outbuilding. Couldn't ask for better. Highly recommended.Posted on Google![]()

Major flood in my garden, reached out to Ardent, as a neighbour had used them. Super fast response, people to my property quick, assessment completed quickly, proposed work decided quickly, Steve and his team worked super hard for days, where polite, professional, worked diligently, showed me there progress daily. Would highly recommend this group of nice people to any one with garden issues.Posted on Google![]()

Fitted a new water main within a matter of hours. Left the path and inside of the house spotless and very friendly company to deal with. They sort all the paperwork with United Utilities, and they make it a very simple process. Would 100% recommend to anyone.Posted on Google![]()

I cannot praise the company enough. They work they did on our rear garden to stop the surface water laying there is first class. Moreover, the garden looked as good after they finished as it did before. I am delighted with the outcome. Thank you Ardent UtilitiesPosted on Google![]()

I fully echo the positive reviews shared here. I appointed Ardent Utilities to replace an old lead water main, and the service from start to finish was outstanding. From the initial communication with Kirsty to the site inspection with Mark, and finally the work carried out by the team on the ground — every stage was handled professionally and efficiently. The work was completed to a high standard, and the site was left clean and tidy. I wouldn’t hesitate to recommend Ardent Utilities and would gladly use them again.Posted on Google![]()

What can I say? This company is a fantastic option for any work you require. Mark came out and gave me an estimate for replacing a water supply pipe to my property, which was a really great price. The work was done with no fuss. The 2 guys were very polite and professional executed the job brilliantly infact so good you couldn't tell they had been.Posted on Google![]()

A clear approach to investigating the problem, locating the affected pipework and deciding the right way to put it right.
Let us know what you've noticed, where water is appearing and any changes to the water supply.
We assess the underground supply and investigate where the escaping water may be coming from.
Specialist equipment is used where suitable, with further investigation or targeted excavation if required.
We carry out the appropriate repair or recommend replacement where that is the better solution for the supply.
Straightforward answers to common questions about finding underground leaks, repairing damaged supplies and what happens when the problem isn’t immediately visible.
We assess the underground supply and can use specialist listening equipment to help locate escaping water. Further investigation or targeted excavation may sometimes be required to pinpoint the affected area.
No. Water can travel through the surrounding ground before reaching the surface, so the visible wet area may be some distance from the actual location of the leak.
Yes, although leaks from plastic supply pipes can be quieter than leaks from metal pipework. This can make them more difficult to locate acoustically, so further investigation may sometimes be required.
Not always. Where detection equipment cannot pinpoint the leak accurately enough, targeted excavation may be required to narrow down the affected section of underground pipework.
Where a repair is appropriate, the damaged section of underground supply can be repaired. The location, condition and accessibility of the existing pipework will help determine the right approach.
Replacement may be the more appropriate option where a repair is impractical, access to the damaged section is particularly difficult or the condition of the existing supply makes replacement a better long-term solution.
Get in touch and tell us what you have noticed, including where water is appearing and any changes to the water supply. We can then help establish what investigation is required.
