Combined water and sewerage bill typically splits 40% water supply + 60% sewerage:
| Service | What It Covers | % of Bill | Avg Cost (£603 bill) |
|---|---|---|---|
| Water Supply | Treating raw water, maintaining pipes, pumping stations, reservoirs, customer service, meter reading | 40% | £241 |
| Sewerage (Wastewater) | Collecting wastewater, sewage treatment works, sewer maintenance, pumping stations, environmental compliance | 50% | £302 |
| Surface Water Drainage | Rainwater drainage from roof/driveway into sewers (if applicable) | 10% | £60 |

Surface water drainage: If your property has soakaway/septic tank (rainwater doesn't go to sewers), you can apply for surface water drainage rebate - removes 10% from bill = saves £60/year average. Check with water company if eligible.
Water bills typically charged twice per year (April + October):
No - water is regional monopoly. Unlike energy, you CANNOT switch water supplier. Your property's location determines supplier - Thames Water if in London, Yorkshire Water if in Yorkshire, etc. No competition, no switching. Ofwat regulates prices to prevent monopoly abuse, but limited choice means customers stuck with poor performers (Southern, Thames).
Infrastructure costs, performance history, and geography vary drastically:
Multiple support options available - don't ignore the bill!
