The Crucial Cover: Why You Must Insure Your Property at Contract Exchange

18 November, 2025 3 minutes reading time


Securing Your Investment

The process of buying a house is complex, and therefore, it involves many legal steps. As a result, one essential requirement that demands careful attention is having buildings insurance from the moment you exchange contracts. This crucial stage is often overlooked or postponed, yet it is vital for protecting what is likely the most valuable investment you will ever make.

When the Risk Becomes Yours 

Crucially, when you exchange contracts, the legal risk immediately transfers to you, the buyer. Although you don’t legally own the house yet (that happens at “completion”), any damage that occurs during that period becomes your responsibility.

For example, as the buyer, you are required to buy the house even if it burns down or floods. Therefore, the seller is no longer liable for any damage; the risk now lies with you. The insurance company steps in to provide funds for repair.

Additionally, if you are applying for a mortgage, the lender will require this insurance. They are lending a significant amount of money, so their investment must be safeguarded. Without proof of insurance, a mortgage cannot be secured, and the house purchase cannot go ahead. 

Why You Need Cover

Imagine a fire or severe storm damaging the house just before your move-in date—protection against such unforeseen events is vital.

For instance, if a fire causes damage, insurance will cover reconstruction costs. Similarly, strong winds during a storm can damage the roof, and repairs will be covered by your policy. Floods resulting in water damage are also protected, ensuring you won’t have to bear the financial burden alone.

Without insurance, any damage would mean you pay out of pocket for repairs or rebuilding, which could lead to serious financial hardship.

Keep Completion Running Smoothly

Significantly, your legal team must verify that you have valid insurance before the completion date. Without this proof, the entire process could be delayed, risking postponement of your move and causing unnecessary stress.

It’s important to note that buildings insurance should start on the exchange of contracts; therefore, neglecting this can lead to serious financial issues. This insurance acts as a safety net, protecting your entire purchase from potential risks.

Leasehold & New-Build Properties

Special situations must be considered for specific property types: 

  • New-Build Homes: As the buyer, you usually bear the risk from exchange until completion. However, if the property is only partially constructed, this period can be lengthy, and securing insurance may be challenging. You might prefer the developer to insure the property until all works are completed. 

Simple Insurance Checklist

Use this simple list to make sure your new policy is set up correctly: 

Items to CheckCover Required
Rebuild CostDoes the amount cover the full cost to rebuild the house (not just its market value)?
Start DateIs the insurance active from the day you exchange contracts?
Lender NameIs your mortgage lender's name listed on the policy?
What's CoveredDoes it include events like fire, storm, and flood?
Empty House RuleIf the house is empty for a while, are you still covered? (Check the time limit)
The ExcessHow much will you have to pay toward any claim before the insurance takes over?

This quick check ensures the legal rules are adhered to and your new home is safe from the moment the contracts are signed.
