Do you need building regulations approval for an extension?
In most cases, yes.
Even if planning permission is not required, your extension or conversion will usually still need to comply with building regulations.
These rules are there to make sure the work is safe, structurally sound, energy efficient, and built properly. They can cover things such as insulation, drainage, ventilation, fire safety, structural work, and electrical requirements.
This is one of the reasons we always recommend getting proper advice early. It helps avoid delays, unexpected costs, and problems later in the project.
At RG Developments, we make sure every build is approached properly, with the right attention given to both the design and the practical details behind it.
