Why Self-Build Insurance?

You should arrange your self build site insurance from the moment your purchase your plot to make sure you, your self build project, your employees and any existing structure are protected throughout your build. Most self builders don’t realise that the moment you complete your plot purchase you need a minimum of public liability cover to protect you while you seek planning. If you intend to start building straight away, a self build site insurance policy may be a better option as all of our self build site insurance policies include public liability and employers’ liability cover as standard. Our self build site insurance policies are flexible and can be bought for varying periods of time from 3 months to 24 months.

Our self build insurance cover doesn’t stop there, you can also purchase our 10 Year Structural Warranty which protects your home for 10 years from completion against defects in design, materials and workmanship. Should you wish to sell your property at some point in the future, a Self-Build Zone Structural Warranty will give your purchaser the peace of mind that it is covered by a lender-approved Structural Warranty. Our self build structural warranties are approved by UK finance and backed by ‘A’ rated insurers to give your self builds the best possible protection. We also have our own in-house technical team who can facilitate your buidling control and technical audit site visits throughout your build giving you an alternative to the local authority.

Each member of our team is trained to help discuss your project and its specific self build insurance needs so we can make sure you have the best possible protection for your self build.
