Leak Detection in Lerwick
Lerwick's soft water chemistry creates a specific leak profile: pinhole corrosion in copper fittings and degraded lead joints are the leading causes of hidden water loss in Victorian and Edwardian properties. In modern Lerwick homes, plastic pipe stress and misconnections in the separate sewer system produce different leaks. Whether your bill has crept up, or you suspect a leak behind walls in ZE1, ZE2, ZE3, or ZE4, Scottish Water's metering and our leak-detection expertise will pinpoint the source.
Leak detection in Lerwick uses thermal imaging, acoustic sensors, and water-meter analysis to find pinhole corrosion in copper, degraded lead solder, and cracked plastic pipes. We serve ZE1–ZE4, specializing in soft-water corrosion and Lerwick's separate sewer misconnections. What leak detection costs in Lerwick depends on how easy the leak is to trace and how much pipework is affected.

Drainage in Lerwick — what local engineers know
Lerwick's water supply from Scottish Water is soft and slightly acidic—ideal for reducing limescale, but harsh on metal pipework. Copper supply pipes develop pinhole leaks within 30–40 years; lead solder joints fail even sooner. Properties built before 1970 across ZE1, ZE2, ZE3, and ZE4 are at high risk. Modern Lerwick properties face different issues: plastic pipes cracking under ground shift, or fittings loosening due to vibration. Shetland Islands' local flood risk designation means hidden leaks also raise damp risk in basements. Scottish Water can meter usage; our thermal imaging and acoustic listening pinpoint hidden leaks behind walls, under floors, and in the separate foul/surface systems.
- Soft water supply reduces limescale, but slightly acidic pH can accelerate corrosion of copper fittings and lead joints in older Lerwick properties
- Separate sewer system across most of Lerwick: misconnections (e.g. washing machines plumbed into surface water drains) are a known local issue and can result in environmental enforcement action
- Moderate flood risk in parts of Lerwick — drainage systems near low-lying areas can surcharge after prolonged rain, and sump pump maintenance is advisable
- Freeze-thaw cycles in Lerwick regularly crack exposed copper pipework, outdoor taps, and uninsulated sections in unheated outbuildings

Who's responsible for drains in Lerwick?
In Lerwick, responsibility for a blocked or damaged drain depends on where the fault sits. As a homeowner you are responsible for the drains within your property boundary that serve only your home. Since the 2011 private sewer transfer, Scottish Water is responsible for shared sewers and lateral drains beyond your boundary — even where they run under private land. Road gullies and highway drainage are maintained by Shetland Islands.
This matters because it determines who pays. If our engineer's CCTV inspection shows the fault is in a shared sewer, we'll tell you — and you can report it to Scottish Water rather than paying for the repair yourself. The separate sewer layout that dominates Lerwick affects where these boundaries typically fall, and our local engineers know the ZE1, ZE2, ZE3 networks well enough to identify ownership quickly.
Leak Detection prices in Lerwick
Every Lerwick job is quoted as a fixed price before work starts — what we quote is what you pay, with no call-out fee for providing the quote. However, the final price depends on access (an external inspection chamber is quicker than internal-only access), the pipe material and condition , and how established the blockage or fault is. Request your free quote and we'll confirm the price and your engineer's ETA in the callback.
In summary, Leak Detection in Lerwick is backed by a 12-month workmanship guarantee. Furthermore, every job includes a written completion report. Consequently, you have full documentation if the same fault recurs.
