What will happen if my windows do not comply with Building Regulations?

If replacement windows or doors do not comply with Building Regulations, there can be consequences for both the installer and the homeowner.

• The installer may face enforcement action and could be subject to penalties for failing to comply with Building Regulations.
• Non-compliant installations may not meet required standards for safety, ventilation, structural performance, or energy efficiency.
• In some cases, defective work could pose risks to health and safety.
• Your local authority may require non-compliant work to be corrected, which could result in additional costs.
• When selling your property, you may be asked to provide evidence that replacement windows and doors comply with Building Regulations. The absence of a valid compliance certificate can cause delays or complications during the conveyancing process.

For these reasons, it is important to use a properly registered installer and ensure you receive the relevant Building Regulations Compliance Certificate once the work has been completed and certified.
