This is who Comet used for extended warranties etc..
>Domestic and General<
Comet tried to flog me the warranty when i bought my 37WLT68 Tosh (superb 1080 tv

by the way)... It comes with a year warranty anyway.. so thought i would leave it..
Anyway, went onto Domestic and generals site to sort it out myself and it was much cheaper!! LOL!! So give them a try.. they do most stuff...
Cheers
