  • Do not pay more deposit than your supplier is insured for.
  • When paying a deposit or staged payments consider which method of payment you will use

  • Know the terms of the guarantee for the work the supplier is undertaking and how long that lasts for. Additionally check whether it covers the materials or just the labour to correct any defects.

An insurance backed guarantee will safeguard your investment in your new window and doors. It is a policy guarantee that is issued to you, the homeowner, by an insurance company.

Firstly this guarantee underwrites and enforces any guarantee provided by the installer. Most installer guarantees last for 10 years, but if your installer ceases trading their own guarantee becomes worthless.

Before placing an order, always as to see a copy of the IBG and ensure that you get your own before the installer leaves your home after completing installation.

Just like the IBG, the deposit indemnity guarantee covers your deposit if the double glazing installer ceases trading before your windows are installed.

Deposit protection insurance usually covers from 10% to 25% of the total value of your project and there is usually a maximum coverage. Make sure you never pay more deposit than what your installer is insured for.

Lastly, they have a limited time period so also check the installation will be completed within that time frame or get the policy extended.
