⚠️ Unmetered Bills Can Be Expensive
If your rateable value is £250+, unmetered bills can exceed £950/year even with low water usage. A water meter could save £300-450/year for typical households. Request FREE meter installation from Northumbrian Water with 2-year trial period - switch back if it costs more.
Assessed Charges (Fixed Annual Fee)
For properties without rateable value (built after 1990) that don't want a meter:
Standard Assessed (2+ people): Assumes 120 m³/year usage - £238 water + £287 sewerage = £525/year (Northumbrian Water)
Single Occupier Assessed: Assumes 60 m³/year usage - £149 water + £206 sewerage = £355/year (Northumbrian Water)
Eligibility: No rateable value AND choose not to have meter installed
Which is cheapest? For typical 3-person household using 120 m³/year: Metered = £506 (cheapest), Assessed Standard = £525 (+£19), Unmetered RV £200 = £761 (+£255). Water meter saves money for 70% of households.
Should You Get a Water Meter?
You'll SAVE Money With a Meter If:
High rateable value (£250+): Unmetered bills £950+ but average usage 120 m³ = metered £506. Saving: £400+/year
Fewer people than bedrooms: 2 people in 3-bed house use 80 m³ = metered £404 vs unmetered £761 (RV £200). Saving: £350/year
Water-efficient household: Showers not baths, efficient appliances, garden not watered = 90 m³ usage = metered £449. Saving: £300/year vs typical unmetered
Working away frequently: Empty house weeks at a time reduces usage to 70 m³ = metered £380. Saving: £370/year
New build post-1990: No rateable value so assessed £525 vs metered £506 typical. Saving: £20-200/year depending on usage
You'll PAY MORE With a Meter If:
Low rateable value (under £150): Unmetered bill only £550 but 120 m³ usage = metered £506. Similar costs or meter slightly more
Large family high usage: 5+ people using 200+ m³ = metered £665 vs unmetered £761 (RV £200). Costs similar, meter gives control
Water-intensive lifestyle: Daily baths, large garden watering, power showers, inefficient appliances = 180+ m³ usage = metered £620+

Understanding Your Northumbrian Water Bill
Bill Components Explained
Standing charge: Fixed daily charge for maintaining supply network. Metered: 16.4p/day water + 34.2p/day sewerage = 50.6p/day = £185/year before any usage
Volume charge: Pay per cubic metre used. Water £1.49/m³ + sewerage £1.35/m³ = £2.84/m³ total. Average 120 m³ = £341/year usage charges
Total metered bill: £185 standing + £341 volume = £526 typical (slightly higher than £506 average due to rounding)
Bill Frequency & Payment
Metered bills: Every 6 months based on meter readings (April and October typically)
Unmetered bills: Monthly by Direct Debit or annual/half-yearly by other payment methods
Payment methods: Direct Debit (cheapest - no fees), online, phone, PayPoint, standing order, cash/cheque
Direct Debit discount: None currently - all prices same regardless of payment method (unlike energy)
What's Included in Sewerage Charges?
Foul water: Sewage from toilets, sinks, showers, washing machines - treatment at sewage works
Surface water drainage: Rainwater from roof/driveway draining to public sewers - collection and treatment
Full service (£124.93 standing): Foul + surface water drainage included
Foul only (£44.71 standing): No surface water to public sewer (soakaway, private drainage) - 64% reduction!
Check your drainage: Not sure if surface water goes to public sewer? Contact Northumbrian Water for free drainage survey - could save £80/year
Essex & Suffolk Water Differences
Water only: ESW provides water only - sewerage billed separately by Thames Water (south) or Anglian Water (north)
Typical total bill: ESW water £228 + Thames sewerage £250-300 = £478-528/year combined
Two separate bills: You receive water bill from ESW and sewerage bill from Thames/Anglian - pay each separately
Rates slightly lower: ESW water rates £1.4234/m³ vs NW £1.4873/m³ (4% cheaper) but sewerage similar when combined

Contact Northumbrian Water online at nwl.co.uk/meter or call 0345 717 1100. Free installation within 3 months, 2-year trial to switch back if costs more. No obligation or charges.
Can I switch back to unmetered if meter costs more?

What if I can't find my rateable value?
Contact Northumbrian Water customer services - they have your RV on file. Alternatively, check old council tax bills from before 1993 (when RV system ended). Typical range: £120-£300 for average homes.
Why did my bill increase 19% this year?
Ofwat (water regulator) approved £79 increase (19%) for 2025/26 to fund £2.9 billion infrastructure investment: fix leaks, upgrade sewage works, improve water quality, replace aging pipes. All UK water companies increased bills 20-30% this year.
Do I pay water rates if property empty?
Metered: Pay standing charges only (£185/year) if no usage. Unmetered: Pay 50% reduction after 6 months empty. Must notify Northumbrian Water property empty to get discount.
What if I'm struggling to pay my bill?
Contact Northumbrian Water immediately - they offer: WaterSure (cap at average bill for benefits + high usage), Social Tariff (reduced bills for low income), payment plans (interest-free installments), debt forgiveness (write off arrears for eligible customers). Never ignore bills - help available.
How accurate are estimated bills?
Estimated bills based on previous usage or typical household. Can be 20-50% wrong if your usage changed. Always submit actual meter readings every 6 months when billed to avoid shock catch-up bills or overpaying.
Can I have separate water and sewerage meters?
No - sewerage assumed to equal 95% of water usage (5% for garden/car washing doesn't go to sewer). One water meter measures both water in and sewerage out.
What happens if my meter breaks?
Contact Northumbrian Water - free meter replacement within 7 days. Bill estimated based on previous usage while meter broken. Northumbrian Water responsible for all meter maintenance/repairs at no cost to you.
