In the past I've helped people wirh interference-issues by getting them to replace the ubiquitous 4- or 6-way trailing-sockets you find behind every telly these days with one containing interference suppressors.
You also used to be able to buy spike/RFI-suppressors that looked like a slim 13A adaptor: plug it into the socket then plug the appliance into the suppressor - though I can't remember where these came from.
I've also in the past used IEC309 male/female cables that have built-in interference suppressors - these are great for shutting-up noisy PCs and monitors.
