Hi Tony,
I'd try a battery pack instead of the wall-wart. If it's an ebay china special it may be pretty bad. Why are you using DCF rather than MSF? I have an old Radiocode Clocks MSF receiver running in the garage without a problem, I'm in Cambridge too.
Many years ago I tried a MSF receiver based on a Cirkit kit. Never got it to work, mostly due to intereference from the Z80 micro.

So I'm using a cheap and cheerful (there's a theme here) wall wart with
micro-USB connector which I guess is pretty horrid in this regard. The
other possibly relevant thing is the HDMI connection to the display.
