Smart metering strategy

Here, you can read more about our smart metering plan for non-household (NHH) customers. This is critical for accurate billing, consumer behaviour insight and reducing leakage.

background

Our NHH Smart Deployment Strategy

There is a significant opportunity for smart metering in the non-household sector. 3% of NHH customers use 70% of the total NHH consumption, which is 20% of all consumption*. *Source: MOSL Non-Household Metering Special Report

How many?

Our ambition is to exchange all NHH meters in AMP8 (Apr 2025 to March 2030). This includes 51k non-Household meters in AMP8. The majority of planned exchanges (44k) are on 15-22mm meters.

Where?

The order of deployment is based on water resource strategy and prioritises water scarcity. We'll have a phased area rollout across AMP8 18-month deployment profiled for each water resource zone (WRZ).

How?

We'll install AMI-capable meters from now onwards. Flexible, smart communications across our region. We plan to pilot a solution in AMP7, and then scale up in AMP8.

Creating a resilient water future

Smart metering across domestic, retail, and non-household customers will contribute to the broader Water Network Resilience Strategy by:

  • Reducing leakage by more than 50% by 2040
  • Delivering Target 100 by 2039
  • Achieving our non-household retail market ambitions for water efficiency

We had a large-scale exchange programme between 2010 and 2017. This culminated in 88% meter penetration across our estate.

The AMR meters fitted as part of the last programme are now reaching the end of life. Now, we have the opportunity to upgrade our infrastructure and collectively benefit from the power of smart data.

Frequently asked questions

Find out more about our smart metering strategy for retail and other NHH customers. 

Our ambition is to exchange all NHH meters in AMP8, from small meters through to large. This gives all metered customers the opportunity to benefit.
The majority of exchanges will be screw-out/screw-in replacements, with minimal risk to water quality and interruption to supplies. Where a dig or internal fit is required, we'll notify you in advance so you'll have time to prepare for any interruptions or to arrange access to your meter.
We have a plan which outlines which Water Resource Zones we'll target and when. As we roll out our smart metering strategy, we'll give retailers a more detailed view of where and when meters will be installed. This will likely be supplied by a third-party installation partner.
We are still working on defining this. Currently, we're engaging with industry partners and retailers to understand their requirements and how we can provide the most relevant service.
We'll aim to reinstall or return any existing loggers to the retailer, where necessary.
