With summer just around the corner, now is the perfect time for businesses to get ahead of costly water leaks. In the warmer months, increased consumption can mask the tell-tale signs of a leak, which could lead to unexpected spikes in usage and surprise bills.
Unfortunately, many water retailers still fail to take over 20% of the meter readings they’re responsible for, with rural customers especially affected. Missed readings mean leaks can go undetected for longer, potentially costing businesses thousands.
At Castle Water, we’re proud to continue defying industry norms in 2025. We remain the only major retailer with our own highly trained, in-house meter reading team. Our current meter reading success rate exceeds 96% as of May 2024, far outperforming the industry average. Our field staff are not under pressure to hit daily meter reading targets, giving them time to access even the most remote or hard-to-reach meters.
We also encourage our customers to submit monthly readings via the online customer portal. This helps ensure bills are accurate, prevents under, or over-estimations, and provides early warning signs of irregular consumption that may indicate a leak.
How much does a water leak cost?
Water leaks are usually unexpected, often invisible, and can be very costly. A moderate leak (1 litre per second) on the mains could significantly impact efficiency, adding approximately £55,000 to an annual water bill. With costs for businesses rising across all sectors, it’s essential that businesses can find low cost ways to spot leaks early and improve water efficiency to reduce water usage and costs.
Detecting a leak
A simple and effective way to check for leaks is to monitor your meter readings overnight, when usage should be minimal. Higher than expected overnight flow can be a red flag.
To make this easier, many businesses are now installing water meter reading devices, which automatically transmit readings and help detect anomalies in real time.
A low budget solution
For businesses looking for a cost-effective solution, Limpet readers are a smart option. These devices attach to your analogue water meter and provide accurate readings straight to your mobile device. Walk within range of your meter, and your latest reading is sent instantly.
Limpet readers are quick and easy to install, and are typically up and running within 15 minutes. In 2025, newer models even offer dashboard integration, giving you a clear view of your usage patterns and potential leaks.
