I need an experienced and qualified plumber or water leak-detection specialist to inspect my property in Leyton, East London. Background: My Thames Water bill shows extremely high consumption of 459,000 litres (459 m³) over 166 days (11 April–23 September 2026). This averages 2,765 litres daily. Thames Water has increased my monthly Direct Debit to £688. I suspect a hidden leak, faulty meter or another plumbing issue. Work required: 1. Inspect all toilets, taps, showers, baths, pipes and water tanks. 2. Check internal and external water supply pipes for hidden leaks. 3. Test the water meter with all taps and appliances switched off. 4. Investigate any continuous or unexplained water flow. 5. Check for possible underground pipe leaks. 6. Establish whether the water supply serves only my property. Evidence and Guarantee Required: Please provide: * A written inspection report. * Photographs and videos of the inspection. * Recorded meter readings and test results. * Written confirmation stating whether any leakage was detected. * If no leak is found, confirmation that no leakage was detected in the areas and pipes tested. * If repairs are undertaken, a written workmanship guarantee. I need this independent evidence to submit to Thames Water so they can investigate and review my unusually high bill and monthly Direct Debit. Important: Please quote for inspection, testing and the written report. Any repair work must be quoted separately and approved by me before proceeding. Applicants must have relevant qualifications, professional leak-detection equipment and experience. I am looking for a reliable specialist who can provide proper testing and documented evidence, not just a visual inspection.
