Northumbrian Water ‒ Cost Efficiency Draft Determination Appendix
July 2019 Trust in water Northumbrian Water ‒ Cost efficiency draft determination appendix www.ofwat.gov.uk PR19 draft determinations: Northumbrian Water - Cost efficiency draft determination appendix PR19 draft determinations: Northumbrian Water - Cost efficiency draft determination appendix 1 PR19 draft determinations: Northumbrian Water - Cost efficiency draft determination appendix 1. Wholesale water activities 1.1 Enhancement The tables below summarise the adjustments we make to set the efficient level of enhancement totex for the water resources and network plus water price controls. Where appropriate, we reallocate enhancement expenditure between enhancement activities. In the table, we present the company requested cost for each activity where we made a material challenge, after any reallocation that we may have done. Our disallowances to company enhancement proposals include a challenge on the need to invest, on the efficiency of the proposals or on the classification of the expenditure as enhancement (in which case we consider that the expenditure is covered by our base allowance). For draft determinations we make an adjustment to the enhancement allowances to account for an implicit allowance for enhancement opex included within our base models. We set out our method of estimating the opex implicit allowance in ‘Securing cost efficiency technical appendix’. Costs for new developments, new connections and addressing low pressure are now considered within wholesale water base (“botex plus”) econometric models. We show details -
Charges in 2021-22 and CMA Redeterminations
Centre City Tower, 7 Hill Street, Birmingham B5 4UA 21 Bloomsbury Street, London WC1B 3HF By email Anglian Water, Bristol Water, Northumbrian Water and Yorkshire Water Business retailers NAVs MOSL CCW Other parties 8 January 2021 Dear stakeholder Charges in 2021-22 and CMA redeterminations This letter sets out our view on the appropriate approach to making adjustments to normal charging arrangements to support the implementation of the CMA redeterminations for the four disputing companies. We are setting this out now to facilitate company statements on significant changes in charges which are due to be published on 11 January 2021 and wholesale charges which are due to be published on 13 January 2021. Four companies: Anglian Water, Bristol Water, Northumbrian Water and Yorkshire Water have asked the CMA for a redetermination of their price controls for the 2020-25 period. Following a request from three of the disputing companies for amendments to the charging rules to allow implementation of the CMA’s redetermination, my letter of 21 December 2020 consulted on the practical consequences and impact of making an accommodation under our normal charging rules with respect to three options for the implementation of the CMA’s redetermination: Implementation of changes over 4 years from 1 April 2021, which three of the four disputing companies (Anglian Water, Bristol Water and Northumbrian Water) suggested would be possible if the CMA issued its redetermination no later than the week commencing Monday, 8 February 2021 and Ofwat allowed them to publish 2021-22 charges no later than Friday, 19 February 2021. Implementation of changes during the 2021-22 charging year, which would allow charges to change during the charging year (potentially after six months) to reflect any differences in the price limits that the CMA sets such that the CMA’s price limits are smoothed over 3.5 years. -

Writing on Behalf of Click and Type Name of Networks
Press Release Utility Networks Partnership 24 June 2020 United front by utilities to help customers in vulnerable situations People who need extra help during a water, electricity or gas emergency will benefit from a new partnership approach by 12 utility companies. They have created a joint video to promote the Priority Services Register, a service that all utilities provide for people needing extra support for a variety of reasons. The companies involved are all members of the Utility Networks Partnership and are already working closely together to help customers living in vulnerable circumstances. They are Affinity Water, Anglian Water, Northumbrian Water, Essex and Suffolk Water, SES Water, SGN, South East Water, Southern Water, Thames Water, UK Power Networks Cadent Gas and Cambridge Water. Andy Clowes, Head of Customer Insight and Strategy, South East Water said: “Taking care of our customers is at the heart of everything we do. “That’s why across the utility sector we have come together to make the Priority Services Register even easier to use, giving our customers extra support when they need it most. It’s completely free of charge and it’s simple to sign up.” Kerry Potter, UK Power Networks’ consumer vulnerability manager, who chairs the Utility Networks Partnership, said: “It’s fantastic to work as a team to create a new video promoting the Priority Services Register which is making it easier for eligible people to get support. When 12 utility companies share a consistent message, we can help far more people. “Collaboration is key to tackling vulnerability and our utility networks group work together to provide consistent services for vulnerable customers in the regions we serve.” Press Release Utility Networks Partnership Thirty-five charity partners have helped develop the video to increase awareness about the free help available from utilities in the event of a gas, water or electricity outage. -

Water Hardness
Water hardness Northumbrian Water is responsible for supplying a reliable source of safe, clean, drinking water. The majority of the company supply area is soft to slightly hard. Why some water is hard If your water comes from underground limestone or chalk rocks, or contains a proportion of groundwater, then the chances are that it is hard. The hardness is caused by the presence of minerals dissolved from the ground and rocks by the water. Northumbrian Water is compliant with the appropriate regulations and has no plans to introduce softening to hard water areas. Please find below a PDF document of the water hardness for the Northumbrian Water area, along with the measurement of hardness in degrees Clarke, for use with dishwashers and washing machines. You can check out how hard the water is in your area here by viewing the harness zones. What does this mean for my appliances? If your water is hard you will notice that your kettle and other water heating appliances become furred up with a white scale. You may also find this scale in your bath, sink and shower. It isn't harmful but can be a bit of a nuisance. Hard water can also affect appliances like washing machines, dishwashers and steam irons. If you are installing a new dishwasher, your plumber may ask you for the hardness of your water. If the manufacturer’s instructions show hardness using a different factor, you can convert the values as follows: x 2.5 = calcium carbonate (CaCO3) mg/l x 0.174 = Degrees Clarke Total hardness (as mg/l Ca) x 0.25 = French Degrees x 0.142 = German Degrees We do not change the natural hardness of the region’s water through treatment, it is left to the customer, either domestic or commercial, to decide whether artificial softening is the right choice for them. -
