Bogus callers may try to enter your home by pretending to be from your water, electricity, gas or telephone company.
To prevent this, we operate a doorstep password scheme for all our customers. We regularly seek guidance from the UK water industry to make sure we’re doing everything we can to protect you.
Call us on 0800 316 9800. Lines are open 24/7. When registering, you’ll be asked to provide your name and address. You’ll then be asked to choose a password no longer than eight characters long.
If your hearing or speech is impaired, you can contact us using Relay UK.
Once you’ve registered, any future callers from Thames Water must be able to quote your password before you let them in.
If they’re unable to provide you with the correct password or they ask you what it is, please stop them entering your property and call us immediately on 0800 316 9800.
