Found this cracking deal yesterday. It's difficult to beat, because you get very decent contents cover for free with your buildings cover - and the buildings cover works out very reasonable too. Well worth getting a quote - you can get one up to 90 days ahead of when you need the policy.
The buildings insurance covers you up to £400,000 (fine for most houses!) and the £75,000 free contents insurance should do for most people too.
Plus Quidco if you go through the Quidco link - a generous £75 as well.
From the website:
Get FREE contents cover in the home up to a whopping £75,000 when you buy buildings insurance, for the life of your policy so long as you dont make a claim, plus enjoy a superb 25% discount off your premium.
