You can get the insurance of the heritage house, palace or any other building through listed buildings insurance providers. For insuring such old buildings which are of national interest the broker should have very deep knowledge of insurance terms because it is highly complicated area with lots of clauses.
Identifying Total cost is difficult
Generally, insurance on any building is done after accessing the total cost of the construction in detail. The insurer assumes that the building is completely destroyed and then adds up the brick by brick cost that would be required to build it. Covering this sort of building does require specific knowledge because some buildings are made years ago and the techniques used to build them might not be relevant today. In such case, it becomes even more difficult to access the cost of the property and make assumptions.
It is very much possible that the materials used in setting up that building would not be made up of the standard material that is approved today which is why the insurer who is specialized in these sort of insurance should be hired to take help. You can also take assistance from the trusted and reputed surveyor in the process of searching the best property insurer who is listed as well. There are buildings that are so old that issues like drainage, damp and half destroyed portion occur which make the assessment even more difficult and challenging.
Whoever you choose, make sure that the building is wholly covered and try to understand each and every clause.
