Building Inspection For Window & Door Regulations​

All replacement glass & glazing since 2002 requires some form of Building Regulations. Proof of this is required from a solicitor when selling your home. This evidence, in a form of a certificate, shows the replacement windows comply with the building regulations.

There are two ways in which you can provide this evidence:

A FENSA certificate showing that the work has been completed by an experienced professional installer. This person or company is a member of a ‘Competent Person Scheme’ such as FENSA.


You provide a certificate from the local authority building control that states the works carried out have been approved under the building regulations.

If you choose to complete the work yourself you must contact the local building authority as soon as you can to inform them of your project. You must also supply them with dates for when you plan to commence the works and arrange for them to visit your home, during and after the installation. This is to confirm the work has been completed in accordance with all the regulations that are involved.

Important Note: As the homeowner, it is you that is ultimately responsible for ensuring that all work carried out in your home complies with the regulations and the correct certification is available.

As part of our service when replacing old profiles we take care of this FENSA certification when installing new windows or doors.

There Are Many Parts To Building Regulations

From Parts A to R Building regulations provide detailed technical standards that are broken down into relevant parts.

They cover the major requirements across the design and construction of buildings. Combined they ensure the safety, comfort and health of people within the dwelling.

Considering the energy efficiencies of buildings constructed in the past, these requirements are in place to ensure current thermal performance and required energy efficiencies are achieved. Helping to reduce the amount of condensation and increase comfort in the home.

A brief summary of the parts contains requirements for;

  • structural integrity
  • drainage provisions
  • fire safety
  • ventilation
  • facilities provided for people with disabilities.
