Using thermal imaging, acoustic surveys, and tracer gas testing, our specialists pinpoint hidden leaks fast — without unnecessary damage to your property.
Most leaks don’t start with a flood. They often show up as a higher water bill, damp patches, or a boiler that keeps losing pressure. By the time water is visible, it may already have caused hidden damage.
That’s why we use specialist detection equipment first. Thermal imaging, acoustic technology, and tracer gas help pinpoint leaks with minimal disruption. Once the source is confirmed, we explain the problem, recommend the repair, and can provide a report for insurance claims if needed.

Hi Mohammad , We really appreciate your feedback. And we’re delighted you’re happy with the service provided.Posted on Google M NTrustindex verifies that the original source of the review is Google. Never in my life have I come across a company this professional 👌🏻They explained everything clearly from the start and found and fixed the leak under my shower tray without breaking a single tile. They even put the shower tray and screen back perfectly like nothing had ever happened. Another company quoted me more than double the price, but these guys charged £727 and did an amazing job. Both engineers were amazing.Definitely the best around. Highly recommend.

Hi Andreea, Thank you for your kind words! We’re delighted you had a great experience.Posted on Google Betty CawelyTrustindex verifies that the original source of the review is Google. Aleks from PrimeFix found my leak in an area I would never have expected. It took some time and wasn’t a cheap job, but it was a very difficult leak to find. He worked carefully and managed to locate it with minimal damage. Big thanks to Aleks and the PrimeFix team for their hard work and professionalism. Highly recommended.

Gland we would help and of course we’re always here if you need any further support in the future 🙏🏻Posted on Google Kirsty BrownTrustindex verifies that the original source of the review is Google. ⭐️⭐️⭐️⭐️⭐️ We had an underground leak at my 88-year-old mother’s property and contacted Prime Fix Group Ltd. The engineer arrived promptly and, after carrying out an assessment, called me directly to explain the issue, the required work, and all costs involved, as he did not want to stress my mother with the situation. Very professional service from start to finish with no hidden fees at all. Everything was explained clearly before any work was carried out. We submitted the report to our insurance company, who recognised Prime Fix as highly qualified engineers. Highly recommended.

Every job follows the same process, in the same order. We don’t guess, and we don’t open anything up until we’re certain. Here’s the equipment behind every investigation.

A boiler or system that keeps losing pressure with nothing visibly wrong is often the first clue. We isolate the circuit, bring it up to a controlled test pressure, and narrow down the fault area — usually inside the hour.

Water moving behind a wall or under a floor changes the surface temperature just enough for an infrared camera to pick it up. No tiles lifted, no plaster opened. The camera does the searching first.

A soft patch of floor, a stain that keeps returning, a ceiling mark with no roof leak to explain it. Moisture readings tell us how far it's spread and point us toward the source.

Escaping water under pressure has its own sound signature. Ground mics and pipe-correlation equipment pick it up, even underground or behind finished walls.

For the leaks that won't show up any other way, a safe hydrogen-nitrogen mix is fed into the system and followed with sensitive detectors until it reaches the exact point of escape. It'sour most precise method, reserved for the hardest cases.
Every quote is confirmed in writing before work starts. No call-out fee. No hidden charges.

Common questions about water leak detection, answered plainly. If you don't see what you're looking for, call us on 02081080400 and we'll talk you through it.
Our leak detection call-outs are charged hourly — £85 +VAT covers the first hour, then £42.50 +VAT for each half-hour after that. There’s no call-out fee, and you’ll get a confirmed price before anyone picks up a tool. Parking, ULEZ, congestion charge and fuel surcharges are never added on top.
Most surveys wrap up in one to two hours, though it depends on the property size and how the pipework’s laid out. We’ll give you a realistic estimate at the time of booking, not after we’ve arrived.
Almost never. Thermal imaging, acoustic tracing, moisture mapping and tracer gas let us narrow down the source before any opening-up work is even considered. Most jobs are resolved without touching a single tile or panel.
Always. Every survey ends with a full digital report covering the leak source, the methods we used to find it, and our findings — written to a standard accepted by every major UK insurer handling trace and access claims.
Both. We run a 24/7 emergency line, 365 days a year, with no out-of-hours surcharge. If it’s not urgent, we’re just as happy to book a slot that suits your schedule.
