Hello, Thames Water says on their website that you should contact them if there is an issue with the street stop valve. I have an issue with mine (it is seized) which I discovered painfully in an emergency. Grrr.
Problem is, I cannot find out to report it online. There is no category in their reporting system.
I couldn’t find this online either. I contacted them via Twitter to say we needed help with ours as it’s seized and we have an extremely leaky inside stop tap. They won’t do work like this in the current COVID-18 climate. So now we are left to foot the bill for a specialist plumber to isolate the flow to our inside stop tap
