Mysterious Water Usage

S

Sandra Kenny-Jones

Hello there. I'm hoping somebody can provide me with some guidance on an issue that's been ongoing now for over 2 years! Thames Water moved my home onto a smart meter and ever since then, the daily water usage is showing that water is being used every night between midnight and 7am. On average, it's in the region of 10-15 litres per hour so a considerable amount. They have confirmed that it's definitely not a shared meter issue and are adamant that I must have something on a timer that is using water overnight, but I don't. I have a Worcester Bosch combi boiler. The hourly water readings are normal during daylight hours and there are several hours where no water is being used in the day so it's definitely not a leak. Clearly I want to try and find out the source of the problem but don't have a clue where to start. Any ideas welcomed. Thank you everyone.

Any idea of who is best placed to investigate? Do I need a specialist of some sort? Thames Water aren't interested as they say their obligation ends at the mains supply on the pavement. :-(

Yes they should have a list to approved contractors but you want the water meter checking first as it might be faulty etc might save you a call out from a pro

Hi there ... the meter is outside on the pavement and Thames Water have installed a new meter but still the same issue. Below is an image of the type of usage overnight - I was actually away from home - water usage overnight - nothing all day and then starts again at 11pm. I'm at a loss as to work out why ...

Thats really weird.

How do you heat your house and water?

Garden irrigation system?

I’m not sure if this has been asked, and I can’t check as the site is advert crazy today. Have you checked the meter serial number with your bill is the same? I think someone could be tee’d off your main?

I wasn't home - I was away. The image shows that even though I wasn't there, I was still "using water" in the early hours of the morning. I have sometimes been away for 3-4 nights and there is NO water used between 8am and 11pm but from midnight through to 8am there is anything between 1 - 15 litres an hour. I'm baffled.
