For indoor leaks, yes – someone over 18 must be present to give us access. For outdoor leaks, we may be able to investigate even if you’re not in. We’ll always let you know in advance what’s required.

Most surveys take 1–3 hours, depending on the size of your property and the complexity of the issue. We always work efficiently and keep you informed throughout.

Yes, we can. If you've received a high water bill due to an undetected leak, we can provide a professional leak detection report with photos and evidence that you can submit to your water supplier. Many water companies will reconsider charges or offer a leak allowance once you prove the issue has been found and fixed.

We offer a fixed call-out fee, which covers our visit and initial assessment. The remaining balance for any repair work is quoted on-site and paid in full on the day once the job is completed
