What Building Regulations mean for your project
Building Regulations are separate from planning permission. They focus on how your extension, loft conversion or renovation is constructed – structural safety, fire protection, insulation, ventilation and accessibility. Getting this right protects your home, your budget and the future value of the property.
At HWP Design & Build we coordinate compliant details from day one, working alongside Building Control and structural engineers where needed. That means fewer surprises on site, fewer delays at inspection stage, and a straightforward route to your completion certificate.
If you are unsure whether you need planning permission as well, our planning permission support service can clarify the route (permitted development vs full planning) before you commit to drawings.
How the process works
We start with a practical review of your scope and existing property. From there we map out the compliance requirements that apply to your build (for example, Part A structure, Part B fire safety and Part L energy efficiency).
Once work starts, we keep inspections moving and make sure documentation is in place. You can also view how we run projects end-to-end on our process page.
We work across East Molesey, West Molesey, Hampton Court, Kingston upon Thames, Esher, Surbiton, Elmbridge and surrounding Surrey & South West London.
