Contrary to what an informant working at the Wembley High Road site told a Wembley resident LINK Henley Homes gave me the following statement today:
Henley Homes are the developer of the former Brent House site.As you are aware Thames Water are currently investigating the source of the concrete in the sewer and will advise in due course.We can confirm, following our investigations, that Henley are not responsible for the alleged blockage of the main drains near the previous Brent House office building on Wembley High Road.
