Bike Insurance

a slightly off topic question, but I want insurance for 2 laptops, 3 bikes and a couple of other valuables for a rented house that I will only live in for 3 months. Does anyone know of a policy that would be a short term rolling policy for contents for rented accommodation, or even one that allows you to switch houses on the same policy?

Endsleigh do short term and on gocompare there is also a tenants insurance policy quote feature
