Every Drop Counts: Fixing the Flow

In this episode, Thames Water’s Andrew Tucker lifts the lid on silent water waste in our homes – and how fixing it can cut tenant bills fast. With the South East at risk of drought within 15 years, water efficiency is no longer optional. It’s essential – for the planet, your residents and your budget. 

1 in 10 homes has a constant leak, often from a toilet – wasting up to 400 litres a day and doubling water bills. 

Thames Water has already retrofitted hundreds of thousands of homes, slashing usage and costs with simple, smart fixes. 

Smart meters are the game-changer – delivering 25 million reads a day, helping detect leaks early and support high-usage households. 

Key takeaways: 

• Fixing leaks saves tenants real money – and supports those in financial stress. 

• Smart meter data = early action + lower costs. 

• Combine energy and water retrofits – same visit, double the value. 

• Free Thames Water Calculator helps residents understand and cut usage. 

• DEFRA’s target: 110L per person/day by 2050 (currently ~140L). 

Call to action for housing providers: 
Work with your water company. Let them in to fit smart meters. Add water-saving to retrofit programmes. You’ll reduce operating costs, protect future supply – and help your tenants lower their bills now.
