Tesco do a year package which you can adapt to include summer and winter sports, we were looking at one of these policies but had already bought our summer insurance.
We were in pamps last year and my sister broke her leg, Tesco insurance were diabolical, she had to pay for her own flight home after loads of arguing and 10 months on she's still arguing about liability with them!. Dont skimp with your insurance mate, do beleive the post office is a good one and thats who we'll be with in february, by the way, the Balkan hols rep. was great and couldnt have been more helpfull so thats nice to know but in this case, it was... Tesco, but very liitle help.
egg.com. The moneysupermarket can be misleading due to the many clauses the sometimes cheaper companies offer. Saying that, I've never had to claim off Egg so am not in a postion to advise how their service stands up.... I would, however, take jonbonce's advice and steer well clear of Tesco.
