Can I insure a house that is not in my name in the UK?

Can you insure house not in your name in UK, generally yes you can get buildings insurance with insurable interest, but you need to have financial interest and owner permission, though most insurers require you be owner, landlord or have mortgage. Insurable interest means you would suffer financial loss if house damaged, for example you live in house owned by parent, or you are buying house but not yet completed, or you are tenant responsible for building under lease, or you have power of attorney. In UK, you can insure house not in your name if you have insurable interest, such as you are executor of estate, you have mortgage on property, or you are landlord with tenant. However, many standard building insurers like Aviva, Direct Line require you be owner or joint owner, so you may need specialist non-standard or unoccupied insurance, and you must disclose ownership, otherwise claim may be denied as no insurable interest. For example, if you live in parent's house, you can get contents insurance easily, but building insurance should be in owner's name, or you can be named as interested party with owner permission. If you are buying house, you can get buildings insurance from exchange of contracts. So you can insure house not in your name in UK if you have insurable interest and disclose, but building insurance typically needs to be in owner name, with you as joint insured or with permission, otherwise contents insurance is easier for non-owners.
