2026-27 Unmetered Charges (Rateable Value)

If you DON'T have a meter, charges based on property's rateable value (RV) and charging zone:

Zone Area Examples Water Rate (£/£RV) Sewerage Rate (£/£RV) Total Rate (£/£RV)
Zone 1Birmingham, Coventry, Solihull0.25050.23560.4861
Zone 2Leicester, Derby, Burton0.20540.19310.3985
Zone 3Nottingham, Mansfield, Newark0.23050.21680.4473
Zone 4Stoke-on-Trent, Stafford0.25050.23560.4861

← Scroll table horizontally on mobile →

Example unmetered calculation (Zone 3, RV £200):
Water: £8.30 fixed + (£200 × 0.2305) = £54.40
Sewerage: £8.30 fixed + (£200 × 0.2168) = £51.66
Total: £106.06/year (£8.84/month)

Much cheaper than typical metered £612/year! Unmetered often better for families with high water usage.

Metered vs Unmetered: Which is Cheaper?

Should You Get a Water Meter?

60% of Severn Trent customers have meters. Whether metered or unmetered is cheaper depends on household size, usage, and rateable value:

✅ Water Meter Likely CHEAPER If:

  • Small household, high rateable value: 1-2 people in Band D-H property
  • Low water usage: Water-efficient appliances, no garden, short showers
  • More bedrooms than occupants: 4-bed house with 2 people
  • High unmetered bill: Currently paying £500+/year unmetered

Example: 2-person household, RV £250, Zone 1
Unmetered: £8.30 + (£250 × 0.4861) = £129.83/year
Metered (80 m³): £110.67 + (80 × 4.18) = £445/year
Unmetered £315/year cheaper! Actually for this case, unmetered is better.

✅ Unmetered Likely CHEAPER If:

  • Large household, low rateable value: 4+ people in Band A-C property
  • High water usage: Daily baths, large garden needing watering, inefficient toilets/appliances
  • Low rateable value: RV under £150 - very cheap unmetered bill
  • More occupants than bedrooms: Family of 5 in 3-bed house

Example: 4-person household, RV £150, Zone 2
Unmetered: £16.60 + (£150 × 0.3985) = £76.38/year
Metered (180 m³): £110.67 + (180 × 4.18) = £863/year
Unmetered £787/year cheaper! Huge saving staying unmetered.
