1. Planning Applications
Purpose:
To seek permission from the local planning authority (usually your local council) for development or changes in land/building use.
When Required:
- Building something new (e.g. a house, extension, garage)
- Major alterations to buildings
- Changing the use of a building or land (e.g. from residential to commercial)
- Some changes to listed buildings or properties in conservation areas
Considerations Include:
- The visual impact and design
- Impact on neighbours
- Environmental factors
- Local planning policies
- Access and parking
Types:
- Outline Planning Permission (to get agreement in principle)
- Householder Application (for small-scale works on a home)
- Full Planning Permission (for bigger projects)
- Listed Building Consent (for works to Listed buildings)
- Reserved Matters (to deal with details following outline approval)
Outcome:
You receive a decision: approved (possibly with conditions) or refused. You usually need this approval before starting work.
2. Building Regulation Applications
Purpose:
To ensure that construction work complies with Building Regulations for health, safety, structural integrity, energy efficiency, etc.
When Required:
- Most building work (e.g. extensions, conversions, structural alterations)
- Installing heating systems, replacing windows, or rewiring (in some cases)
What It Covers:
- Structural safety
- Fire safety
- Drainage and sanitation
- Electrical and gas safety
- Accessibility
- Insulation and energy performance
- And more!
Types:
- Full Plans Application (plans are submitted and approved before work starts)
- Building Notice (for simpler work – no pre-approval but subject to inspection)
- Regularisation (for work done without approval – a retrospective application)
Inspections:
Building Control officers will inspect the work at key stages to ensure compliance.
Outcome:
You receive a completion certificate once work meets all regulations.
Key Difference:
| Planning Permission | Building Regulations | |
| Focus | Appearance, use, and impact on area | Technical standards, safety, and construction |
| Authority | Local planning authority (planning dept) | Building Control (council or private) |
| Needed For | Changes in use, new buildings, extensions | Most building work |
| When to Apply | Before starting any development | Before/during the start of work |
