When embarking on a commercial fit-out or refurbishment project in the UK, navigating the regulatory landscape can be one of the most challenging aspects of the process. Two distinct but equally important sets of requirements—Planning Permission and Building Regulations—govern construction work, and understanding the difference between them is crucial for project success.
As specialists in commercial interior fit-out in Manchester and across the UK, Rische Group’s integrated design solutions and project management approach helps clients navigate these regulatory requirements seamlessly. In this guide, we’ll clarify the fundamental differences between Planning Permission and Building Regulations, explain when each applies, and offer insights into managing compliance effectively.
Planning Permission: Focus on How Development Affects the Area
What Is Planning Permission?
Planning Permission is the approval needed from your local authority to carry out development or make significant changes to a building. It focuses primarily on how the proposed development will affect the local area, neighbouring properties, and the environment.
The Town and Country Planning Act 1990 (as amended) provides the legislative framework for the UK planning system, with local authorities responsible for enforcing planning regulations in their areas. Planning decisions consider factors such as:
Conservation area or listed building status
- Visual appearance and aesthetic impact
- Effect on the character of the area
- Impact on neighbouring properties
- Traffic generation and parking requirements
- Environmental considerations
- Conservation area or listed building status
When Is Planning Permission Required for Commercial Projects?
- Change of Use: Converting premises from one use class to another (e.g., from retail to restaurant or office to residential)
- External Alterations: Making significant changes to the exterior appearance of a commercial building
- Extensions or New Structures: Building additions that increase the footprint or height of the building
- Advertising and Signage: Installing new shop fronts, signage or advertisements that substantially alter the building’s appearance
- Listed Buildings or Conservation Areas: Making alterations to listed buildings or properties in conservation areas
When Is Planning Permission Not Required?
Some commercial refurbishment work falls under “Permitted Development Rights,” meaning Planning Permission isn’t required. This typically includes:
- Internal alterations that don’t change the building’s use
- Minor external repairs or maintenance that don’t materially alter appearance
- Like-for-like replacement of features (within certain parameters)
- Some changes of use between specific use classes (under the revised Use Classes Order 2020)
However, it’s important to note that Permitted Development Rights can be restricted in conservation areas, for listed buildings, or by what’s known as “Article 4 Directions” issued by local authorities.
Building Regulations: Focus on Technical Standards and Safety
What Are Building Regulations?
Building Regulations are statutory requirements designed to ensure buildings are constructed to defined standards relating to health, safety, energy efficiency, and accessibility. Unlike Planning Permission, which considers external impact, Building Regulations focus on the technical aspects of construction and how a building functions.
The Building Act 1984 and the Building Regulations 2010 (as amended) provide the legislative framework for Building Regulations in England and Wales, with similar provisions in Scotland and Northern Ireland under their respective building standards systems.
Building Regulations cover numerous technical aspects, including:
- Structural integrity
- Fire safety and means of escape
- Ventilation and air quality
- Energy efficiency and insulation
- Sound insulation
- Electrical safety
- Accessibility for disabled people
- Drainage and waste disposal
- Protection against falls and impact
When Do Building Regulations Apply to Commercial Projects?
- New Buildings: All new commercial buildings
- Extensions: Any extension to an existing commercial building
- Material Alterations: Changes that could affect compliance with Building Regulations requirements
- Change of Use: When changing the building’s use, even if no physical work is carried out
- Specific Systems Work: Installation or alteration of certain systems including:Heating systems
- Heating systems
- Ventilation systems
- Electrical installations
- Fire detection and alarm systems
- Drainage systems
Limited Exemptions from Building Regulations
There are few exemptions from Building Regulations for commercial buildings, but minor works might not require formal approval, such as:
- Like-for-like replacements of certain components
- Some repairs (though these still need to meet relevant standards)
- Small detached buildings meeting specific criteria
Key Differences Between Planning Permission and Building Regulations
Understanding the fundamental differences between these two regulatory systems is essential for effective project planning:
Different Authorities and Departments
- Planning Permission: Managed by the local planning authority (usually the planning department)
- Building Regulations: Usually overseen by building control departments or approved private sector inspectors.
Different Objectives
- Planning Permission: Concerned with how development looks and impacts the surrounding area
- Building Regulations: Focused on technical standards, safety, and how the building functions
Different Timelines
- Planning Permission: Typically takes 8-13 weeks for standard applications (longer for major developments)
- Building Regulations: Initial approval often faster (typically 5-8 weeks), but includes ongoing inspections during construction
Different Enforcement Powers
Both systems have enforcement mechanisms, but they operate differently:
- Planning Enforcement: Can result in enforcement notices requiring restoration of buildings/land or removal of unauthorised development
- Building Regulations Enforcement: Can lead to prosecution, requirements to rectify non-compliant work, or even demolition in extreme cases
The Practical Application: A Commercial Fit-Out Case Study
To illustrate how Planning Permission and Building Regulations interact in practice, let’s consider a recent commercial interior fit-out in Manchester that Rische Group completed:
Project Overview
A client wished to convert a former retail unit into a modern office space with client meeting rooms, requiring:
- Removal of shop front and installation of new entrance
- Creation of internal partitioning for meeting rooms
- Installation of new mechanical and electrical systems
- Addition of a small mezzanine floor for additional office space
- New kitchen and toilet facilities
Planning Permission Requirements
The project required Planning Permission for:
- Change of use from retail (Class E(a)) to office (Class E(g)(i))
- Alterations to the shop front changing the external appearance
- New signage for the business
The local planning authority in Manchester took 10 weeks to approve the application, with conditions relating to:
- Materials used for the new shop front
- Restrictions on operating hours
- Requirements for bicycle storage facilities
Building Regulations Compliance
Simultaneously, we managed Building Regulations compliance for:
- Structural calculations for the new mezzanine floor
- Fire safety strategy including escape routes and fire detection
- Ventilation system design
- Energy efficiency measures
- Accessibility provisions including accessible toilet facilities
- Electrical installations certification
Building control inspections occurred at key stages:
- Foundation work for mezzanine supports
- Framing stage
- Prior to closing up walls (for electrical and plumbing)
- Final inspection
