• The £250 annual cost estimate is based on a continuous toilet leak (small, slightly visible trickle) of approximately 7 litres per hour over a 12-month period, based on a standard measured charge 25/26 tariff rates for water and sewerage
  • Litres lost daily can be up to 400 litres, based on figures from Consumer Council for water
  • Costs will vary according to leak rate, how long it goes unfixed, household usage patterns and local tariff structure. £250 represents a potential minimum annual cost rather than a guaranteed loss.
  • The "Silent" Nature of leaky look make them invisible and can easily be detected using the toilet paper test
