"While I'm not from Britain, the wife did purchase a hair dryer last year in Scotland and it comes with its own molded plug with built in fuse."

At last, progress. What about England?

The inevitability of RF noise given modern technology is a simple fact of life. We could spend a fortune trying to prevent it from ever being a problem instead of being a problem in rare cases. It wouldn't be worth it. I've built several shielded rooms which were also acoustically dead rooms to measure rf and sound emissions from various equipment to assure complaince to FCC rules. The result is that most of the time, the source is very localized and easy to isolate. Just be glad we live in an age of cable TV and not back in the era which every other guy built a ham radio transmitter and all TV was recieved on an antenna. One of the happiest days I can remember was when a hurricaine blew down a huge transmitting tower one of my neighbors had erected across the street. We never got interference from it again. The only real source of RF trouble I can remember was from WTFM whose transmitter was 6 blocks away. No FCC rules short of shutting them down would solve that. Wait a minute, maybe when they went from horizontal polarization to vertical polarization it got better. I don't remember it was so long ago.
