Google do have comparison services in the UK for some searches.
Try this one for example
http://www.google.co.uk/#hl=en&xhr=t&q=credit+cards&cp=4&pf=p&sclient=psy&site=&source=hp&aq=0&aqi=&aql=&oq=cred&pbx=1&fp=553387615f302e90
It's certainly possible that in the future this will apply to hotels as well. Just something to be mindful of. Many companies have died over night due to changes made by google.
