Door Bell wired added wireless transmitter

[dugit]

Because my hearing is getting worse and I miss the door bell I have been looking for a means of extending my present wired doorbell to have a wireless extender to be wired into my system.
I have seen advertised an rc3200 in the United States : ! The Plug-In Extend-A-Chime expands an existing wired doorbell to be heard in any part of the home. The transmitter connects onto the low-voltage screws in the existing doorbell.
But I cannot find it or an equivalent sold here in the UK?

I can't find any 'extendible' ones but something like this may help.
