Understanding Planning Permission and Building Regulations

Before starting any construction project in the UK, you’ll need to understand two crucial elements: planning permission and building regulations. Planning permission is required for major structural changes or new builds and must be obtained from your local council. Building regulations ensure your project meets safety and energy efficiency standards. Most professional construction companies will help guide you through these requirements, but it’s essential to know that the process can take 8-12 weeks for approval.

Key Stages of Construction Projects

Construction projects typically follow a structured timeline:

  1. Initial consultation and design phase (2-4 weeks)

  2. Planning and permission stage (8-12 weeks)

  3. Detailed design and contractor selection (4-6 weeks)

  4. Construction phase (varies by project scope)

  5. Final inspection and sign-off

Cost Considerations and Timelines

The cost of construction services varies significantly based on location, scope, and specifications. Here’s a breakdown of typical costs for different project types:


Project Type Average Cost Range Typical Timeline
House Extension £30,000 - £50,000 12-16 weeks
Loft Conversion £40,000 - £70,000 8-12 weeks
