Wessex Water's 21-24% bill increases fund multi-billion pound investment program 2025-2030:
Total: £2.8 billion investment 2025-2030 = £560 million/year average, funded by customer bills rising 21-24% 2025-26 then further increases likely through 2030.

However, customers still frustrated paying higher bills for infrastructure that should have been maintained continuously rather than requiring £2.8 billion catch-up investment.

Stay unmetered if:
Example: Family of 5 in £120 RV terraced: Unmetered £406/year vs Metered 200 m³ £597/year = SAVES £191/year staying unmetered.
