Frequently asked questions about Completion Certificate

Do I need a completion certificate?
Yes. For any work that required a Building Regulations application (extensions, conversions, structural alterations), you should obtain a completion certificate. Without it, you may have problems selling the property.
What if I never got a completion certificate?
You can apply for a regularisation certificate from your local authority. They will inspect the work retrospectively and, if satisfactory, issue a certificate. This costs more than the original application would have.
