Clarification of read definitions
Decision

Publication date

Implementation
date
25 August 2023
Background and issue
Under current definitions within the market codes, meter reads taken using a
photograph cannot be used in the market and be classed as a visual or remote read.
This poses a barrier to the use of add-on smart meters in the market, such as the
Limpet Reader, which work by taking a photo of the meter register and convert this into
remotely accessible data.
Verbal evidence provided from Metering Committee conversations have confirmed that
such reads are either not being submitted or are being registered incorrectly in CMOS.
The Metering Committee has also received verbal evidence that some meter suppliers
We are approving this Change Proposal.
CPW141a seeks to clarify definitions of 'visual' and 'remote' meter reads in the market
codes to ensure that outputs from smart meters and add-on devices can be used in the
market. This change will help provide customers with more accurate and timely bills
based on actual meter reads rather than estimated usage.
Ofwat has consistently highlighted that poor quality customer, consumption and asset
data can significantly undermine the customer experience and is one of the three main
'market frictions' that are preventing the market from working effectively and
delivering better outcomes for customers. We therefore consider that this proposal will
help improve quality and accuracy of data in the market, which will benefit the
customer experience.
