Sensitive customers

Following the introduction of competition in the non-household market, it is important that UUW and Retailers have a clear understanding about which premises are occupied by Sensitive Customers. Process E1 describes how the Retailer and UUW shall work together to keep the record of which Eligible Premises are occupied by Sensitive Customers complete and up-to-date in accordance with the Market Terms.

UUW may have Public Health Related Site Specific Arrangements in place for specific Supply Points at Eligible Premises in order to help meet its statutory or other regulatory obligations in the event of a drinking water quality incident, flooding or other event which poses a threat to public health such as environmental pollution.

If UUW needs additional information about any particular Sensitive Customer (or about any particular Eligible Premises not occupied by a Sensitive Customer), for example twenty-four (24) hour on site contact information, it shall establish a Public Health Related Site Specific Arrangement for that Eligible Premises.

As the Wholesaler, UUW do not have access to NHH customer data. Therefore, the Retailer shall keep the information held by the Market Operator on which Eligible Premises are occupied by Sensitive Customers up-to-date by notifying the Market Operator in accordance with the Market Terms and shall so do within two (2) Business Days of becoming aware of any change or during the course of applying for a new connection

The Retailer shall enable UUW to prepare or maintain the Site Specific Arrangement by providing appropriate up to date contact details for its NHH customer along with any other information or assistance reasonable requested by UU. In particular, if requested by UUW, the Retailer shall seek to arrange any meeting between the Retailer, its Non-Household Customer and UUW in relation to the Public Health Related Site Specific Arrangement.

If UUW receives a notification that the Retailer has asked the Market Operator to add or remove a Sensitive Customer flag from any of the Eligible Premises within the UUW area, the Wholesaler may query that change with the Retailer and the Retailer shall respond to any query which the Wholesaler raises.

  • Public Health Related Site Specific Arrangements are generally for eligible premises where there is a permanent duty of care to the general public or a site which could cause risk during an unplanned water or waste incident to the public at large. 

    Those Public Health Related Site Specific Arrangements may mean that UUW needs to hold or have access to up-to-date information about an Eligible Premises, for example twenty-four (24) hour on-site contact details. The Public Health Related Site Specific Arrangements may also require the Retailer to take certain steps to support communication with its Non-Household Customer in the event of an unplanned change to Water Services and/or Sewerage Services.

    PHSSA Criteria

    Tier one (full plan required) High dependency / vulnerable residential population including where relocation is highly problematic.
    • Hospitals
    • Prisons
    Tier two (emergency contact info required) Vulnerable residential population
    • Residential care homes (elderly, infirm, hospices etc.)
    Tier three (emergency contact info required) Non-residential but unacceptable societal impact
    • Educational establishments 
    • NHS Walk-in centres 
    • Day-care facilities 
    • Critical national or local infrastructure (as defined by Government or Local Resilience Forums during planning or response); i.e. establishments which, if they close will have an immediate detrimental effect on civil society or negatively affect a wider incident response (e.g. communications; energy; food production or distribution; emergency services; transport hubs).
    Tier four (emergency contact info required) Agricultural/economic hardship *
    • Premises with livestock, without access to suitable environmental water, where relocation is highly problematic 
    • Other commercial enterprises where available alternative supplies (bottled water, dedicated static tank etc. can maintain their operations)
    *If the higher tier needs have been satisfied, resource permitting, tankered water provision (pumped into private network) may be considered.

     

  • UUW may also have in place Non-Public Health Related Site Specific Arrangements for certain Non-Household Customers, for example if a Non-Household Customer carries out business processes at an Eligible Premises which may be particularly sensitive to changes in the water supply (for example composition or pressure). If the Wholesaler does have any such arrangements in place, this process shall be applied in the same way as for Public Health Related Site Specific Arrangements.

    The Retailer shall inform UUW of any Eligible Premises that meet the above criteria via the template (PDF 322 KB opens in a new window). It is important to note that a NPHSSA does not guarantee the water quality the NHH customer receives but rather acknowledges the sensitivity to change by giving advance warning of change on a best endeavours basis.
