RWG Good Practice Guidance & Adoption

The Retailer Wholesaler Group (RWG) is a trading party group made up of retailers, wholesalers, the non-household market operator (MOSL), the Consumer Council for Water (CCW) and Ofwat. Their aim is to tackle the big non-household market operational issues, make changes and share good practice to improve overall customer service in the market.

We are a member of this group and are continuously working to align with the guides where we can and support the plans to formalise these guides into the codes. Please visit www.mosl.co.uk for access to the relevant guides and their addendums.

Below is our adoption status per guide – as part of this we have highlighted particular instances in which we have not yet adopted parts of the individual guidance or where we attempt to go further than the guidance.

Where the installation of the splitter is carried out by the Wholesaler this will be completed within 22 business days from the request or quote being accepted.	Aligned - we endeavour to complete these within 10BD's for standard requests.
The Wholesaler may install data logging equipment for operational monitoring purposes. This can be either a permanent or temporary logger. Where a Wholesaler is unable to allow a data logger to be fitted due to the presence of an operational (leakage) logger they will either provide a splitter or make flow data available, in accordance with their Terms and Conditions (Policy).	Aligned
The Wholesaler reserves the right to disconnect data logging equipment, even if a splitter is fitted, where it is found to be interfering with the reading of meters or affecting the performance of Wholesaler ancillary equipment (e.g. radio devices or operational loggers). The Wholesaler will provide evidence of the issue caused and will, where possible, try and resolve this with the owner/installer of the data logger. If the issue cannot be resolved the Wholesaler will provide 22 business days notification in advance of disconnection, where the owner of the equipment is known. In certain operational circumstances e.g. a leaking meter it may not be possible to give advanced notice.	Aligned - if the owner is not known (labelled) and/or we have not been notified of the installation we will continue with the disconnection.
Where the Wholesaler identifies high / unusual consumption or leaks on an operational logger fitted to a customer meter, they will endeavour to notify Retailers and/or carry out other leakage investigation work.	Aligned
The Wholesaler is responsible for the maintenance of its data logging equipment, ensuring that it is clearly labelled with a contact name and telephone number.	Aligned
Provision of data from Wholesaler loggers

The Wholesaler will investigate a flat-lining issue within 22 business days of receiving a request. The applicant should notify the Wholesaler direct, in accordance with their Terms and Conditions (Policy) if they become aware of a data flat-line on a Wholesaler’s operational logger (where data is shared).	Aligned

A signed letter of authority (LOA) from the customer is required, where the applicant is not the current retailer. The LOA must cover the period of data sharing.	Aligned
Data Flatlining / Reporting damaged meters
Where it is confirmed that the meter is damaged the Wholesaler should be notified as follows: The Retailer will submit a B/01 (process B5 Retailer Initiated) market form The Third Party will notify the Wholesaler direct in accordance with their Terms and Conditions (Policy). A job report and photos should be provided. The Wholesaler will then notify the Retailer via the B/01 (B5 Wholesaler Initiated) process.	Aligned

The wiring up of loggers is not standard and the Wholesaler may not have experience of the equipment to be re-attached. The Wholesaler will notify the owner of the logger if they are unable to reconnect it.	Aligned - we are unlikely to reconnect any loggers after an exchange so will notify owners in instances that contact details for the owner of the equipment are attached.
Non-loggable meters
Where a meter is > 15years old and is not compatible for logging purposes, the Wholesaler will not charge for the meter exchange. Retailer must submit B/01 form (Process B7). Third party should email us the request and we will notify the retailer by raising the form.	Aligned
Where a meter is < 15years old and is not loggable (eg as a result of a damaged pulse connection point) a charge will be made for the meter to be exchanged (unless the meter is due for periodic/proactive exchange within 6 months). The Wholesaler will notify the applicant as follows; The Retailer will be asked to submit a B/01 (process B7 Retailer Initiated) market form so that a quote can be provided for the meter exchange, in accordance with the Wholesaler's Non-Primary Charges The Third Party will be provided with a quote in accordance with the Wholesaler's Non-Primary charges.

Wholesaler Responsibility
Where premarket opening long unread meters exist, Wholesalers have a responsibility to work with Retailers to resolve these issues.	Aligned
Wholesalers shall make it clear on their website whether they offer a meter reading service to NHH Retailers. It is advisable to publish terms and conditions on websites to improve transparency and ease procurement of services for Retailers.	Aligned
Wholesalers who choose to offer meter reading services to Retailers should ensure the service they provide allows Retailer to perform to the standards set out in the Market Codes (e.g. minimum read frequency requirements).	Aligned - our details are available on our webpages and within the RWG Retailer Information Document.
Meter reading service provider should be prepared to offer ad-hoc meter readings for a variety of different reasons. - Transfer readings – these should be managed in line with the Market Code requirements (two Business Days either side of transfer date) to allow Retailers to meet their obligations. Where transfer readings are taken on behalf of a Retailer, timely feedback of read data where attainable is required to allow the Retailer to submit into CMOS within 2 Business Days of the read being taken. - General ad-hoc – Retailers or their customers may request an off cycle reading for various reasons such as to calculate an allowance, monitor usage more closely or validate reports of damage. Meter reading service providers should consider offering appointments where possible so Retailers can provide their customers with clear expectations. - Types of reading – transfer readings or general ad-hoc readings can be either wireless (where applicable) or manual, to provide a greater level of assurance meter reading service providers should allow Retailers to specify the read type.	Aligned
Regardless of how data is shared with Retailers, meter reading service providers should ensure data includes the below as a minimum: SPID/DPID Premises address MSN Reading or skip Date & time of reading/skip Type of reading (manual or wireless)	Aligned

Planned Activities	Our Alignment - Partial
Wholesaler to NHH Customers
The use of web and social media for all planned activities (D1, D2 & D3)	Partial - use of social media dependent on the nature and impact of the planned works.

We will issue letter drops for D1 and D2 activity however, for D3 activity we do not do this for all incidents.

Wholesaler ‘Pop Up’ campaigns and Public Consultations for all D1 events	Partial - works dependant. We undertake drop-in sessions if works are likely to have a high level of interest/impact - these sessions are notified to customers as part of our initial letters and mail drops for this activity. We also make ourselves available to parish and councillor meetings.
Customer Consultation (D1 and potentially for sensitive customers during D2 and D3)	Aligned - as part of our D1 activity we visit each NHH property when delivering letters with 22BDs notice to give a brief outline of works and to identify any particular needs. We also offer free temporary supplies if water is business critical and will explain that access will not be restricted if customer visits are required, such as shops and surgeries. Hospitals, prisons, care homes and schools are always consulted as part of D1 works to ensure best time and special arrangements are put in place.
Wholesaler to Retailers
The use of alerts (push) to retailers for D1, D2 and D3.	Partial - D1 information is published on our retailer website but not currently pushed to retailers.
