Speak to your insurance company as they can normally arrange to endorse your policy, that provided you take certain precautions, some of the unoccupancy exclusions can be removed. Normally Insurers would exclude theft, water damage and various other perils after 30 or 60 days of unoccupancy.
The precautions required would be that the heating is left on to maintain a temperature of atleast 55F or tanks, pipes and apparatus drained, water turned off at mains and electricity switched off. House to be internally inspected atleast once every ten days. All doors and acessible windows to be locked. etc etc.
The Insurers can also normally extend the personal belongings insurance to cover a longer trip, for an additional premium. This is worth doing as the personal effects cover under Travel Insurance is normally limited.
If you are unhappy with the cover offered by your current insurers, my advice is to contact a good local insurance broker (not Swintons) and they will search for a suitable policy, to meet with your requirements.
