What you need to do

You can either:

  • Use an installer registered under the FENSA scheme run by the Glass and Glazing Federation, in which case you do not need to make a building regulations application to the council. Your installer should then ensure your windows comply fully with the Regulations and will supply you with a certificate confirming this when the installation is complete. You will also be offered the option of taking an insurance-backed guarantee. Please ensure that your installer is properly registered under the scheme before placing an order. You can check this and find more details of the scheme by visiting the Glass and Glazing federation website.
  • Make a building regulations application to your local authority. In most cases the simplest way of doing this will be to submit a Building Notice. You should complete a  Building Notice form, [194KB]  and return it to your local authority together with the appropriate fee at least two working days before removing the old window(s).
  • If everything is satisfactory we will approve the work and provide a completion certificate. This will involve a surveyor visiting your property to check the installation of the new windows.

Costs involved

If you use a contractor registered under the FENSA scheme the cost should be built into the quotation for the works you are given. In all other cases we'll make a charge for dealing with your Building Notice application. You can find information on fees on the main Building Regulations¬†page.

It is important that you get the consent you need as solicitors will make specific checks for this when the property is sold.
