Factors affecting property insurance premiums
Buildings and contents insurance can provide owners with a level of security, and potentially, remuneration following adverse events such as fire, flooding, settlement, structural collapse and public liability.
However, buildings insurance can be costly and a drain on financial resources. It may therefore be in the interests of owners to select and adapt their policies to ensure the best cover at the most affordable cost.
 Multi-year cover
This is the insurance equivalent of buying in bulk. At the outset, it may be possible to arrange a longer period of cover, e.g three years as opposed to annual renewal. This could bring a discount in the region of 5-10% off the premium.
 Selecting the perils covered
Adjusting the extent of the perils covered may also reduce premiums. For example, some policies offer cover against vandalism, but a farmhouse on a remote hillside, or a townhouse in a gated development may be at far less risk of vandalism than other properties. It may therefore be possible to exclude vandalism from the policy and thereby reduce the cost of the premium. The same may apply to perils such as riot and malicious damage, impact by aircraft and falling trees.
 Adjusting the extent of cover
 Reducing the excess
Generally, insurance policies have an ‘excess’ to be paid in the event of a claim. The excess is the amount the insured has to cover themselves before the policy pays out. If the policy has an excess of £500, and water leakage causes £1,000 of damage, the insured will only get £500 from the policy as they have to bear the £500 excess. If on the other hand the damage amounts to £400, it would not be worth making a claim (although the insurer should be notified of the event). The higher the excess the insured is willing to bear, the lower the premium will be.
 Group policies
People over the age of 50 may get reduced premiums through organisations such as Saga, a specialist insurer for older people. Other group policies exist, for example, for owners of historic buildings: churches may get lower premiums through the Ecclesiastical Insurance Group.
