Portsmouth Water has published its draft primary wholesale tariffs for 2017/18 - an accompanying assurance statement from the Board of Portsmouth Water confirms that the Board believes that the draft tariffs and associated Charges Schemes which will apply from 1 July 2017 comply with regulatory requirements.
The assurance statement says that the charges result in compliance with the revenue cap for wholesale and that the costs associated with Open Water are appropriately recovered from Portsmouth Water’s non-household customer base only.
As a consequence of the wholesale tariffs the bill differential for customers using the same volume of water but charged on a different basis, namely measured and unmeasured, is around £30, reflecting the additional cost incurred in metering.
The Watersure tariff is set equal to the average measured household bill – the Board says that as such, it does not believe the tariffs exhibit any undue discrimination between different classes of customer.
The Board has assessed the effects the new charges have on customers’ bills for a range of different customer types - over 30 groups of customer have been reviewed.
The assurance statement says that no group of customers will experience a change in bills greater than 5% as a result of the proposed wholesale price changes.
Portsmouth Water will now consult with the Consumer Council for Water (CCWater) and other stakeholders before issuing its Final Charges Schemes.
