Building Regulations Approval

Building Control: Private vs Local Authority

Building control requirements depend on the project and submission route. Our building regulation drawings are prepared for Building Notice submission, and the selected package sets out what is included.

Building Notice Drawing Scope Included in Pre-Build Package & Premium Package
Building regulation drawings prepared for Building Notice submission
Building Notice submission included in Premium Plus only

Building Notice submission is included in Premium Plus only; the council fee and any provider fees are payable separately.

Local Authority vs Private Approved Inspector

Both options have the same legal authority to approve your building work. Here's how they compare.

Local Authority

Advantages:

  • Public building control service
  • Checks work against applicable Building Regulations
  • Carries out inspections as required
  • Local authority requirements vary by project

Considerations:

  • • The authority sets its own process and timetable
  • • Inspection requirements depend on the project
  • • Fees are set by the relevant authority
  • • The authority determines compliance

Private Approved Inspector

Advantages:

  • A private registered building control route
  • The provider's process and fees are set by that provider
  • Inspection requirements depend on the project
  • The provider determines compliance

Considerations:

  • • The client selects and appoints the provider
  • • Provider fees are separate
  • • Current registration and project eligibility should be checked

The client appoints the building control body. Our packages do not include ongoing coordination with the authority or site inspections.

Building Notice Drawing Scope

Building regulation drawings in our packages are prepared for Building Notice submission. The exact information and any required structural calculations follow the selected package and agreed project scope.

Frequently Asked Questions

Planning Permission controls what you can build - its size, position, and appearance. Building Regulations control how you build it - ensuring the structure is safe, energy efficient, and meets minimum standards. Most extensions need both approvals.

The available route depends on the project and applicable building control requirements. The client appoints the relevant authority or registered building control provider.

The building control body sets its own process and timetable. We do not control or guarantee review or decision times.

The appointed building control body determines which inspections apply to the project and when they are required.

A Completion Certificate confirms your building work complies with Building Regulations. It's essential for selling your property, remortgaging, or proving the work was done properly. Without one, you may face issues with conveyancing solicitors.

Most extensions require Building Regulations approval regardless of size. Even if planning permission isn't needed (under Permitted Development), Building Regulations almost always apply to ensure the work is structurally sound and safe.
