If you’re considering a renovation, extension, or change of use for your property, understanding planning use classes is essential. In the UK, these classifications determine how buildings and land can be used, and transitioning from one class to another often requires planning permission. At Tholos Architects, we aim to demystify the planning process, ensuring your project adheres to regulations while maximizing your property’s potential.
What Are Planning Use Classes?
Planning use classes, established by the Town and Country Planning (Use Classes) Order, group types of property use into categories. These classes help regulate how land and buildings are utilized, ensuring consistency, safety, and community balance.
Main Categories of Use Classes
Here’s a breakdown of the key use classes under the 2020 revised Use Classes Order in England:

Class E – Commercial, Business, and Service
This broad category includes:
- Shops, retail (not takeaways).
- Restaurants and cafes.
- Financial and professional services (e.g., banks and estate agencies).
- Indoor sports and fitness centers, gyms.
- Medical or health services (e.g., clinics and surgeries).
- Creches, nurseries, and day centers.
Key Benefit: Flexibility to switch between uses within Class E without requiring planning permission in most cases.
Class C – Residential
- C1: Hotels, boarding houses, and guest houses.
- C2: Residential institutions such as care homes, nursing homes, hospitals, and residential schools.
- C2A: Secure residential institutions like prisons and young offenders’ facilities.
- C3: Dwelling houses, including family homes, shared housing, and apartments.
- C4: Houses in multiple occupation (HMOs) for 3–6 unrelated individuals living as a single household.
Class F – Local Community and Learning
- F1: Facilities for education, places of worship, museums, libraries, and other non-residential institutions.
- F2: Spaces for community use, such as village halls, outdoor sports venues, or small local shops essential to communities.
Sui Generis – Unique Uses
Some uses don’t fit into any specific class and are considered sui generis. These include:
- Pubs, wine bars, nightclubs.
- Cinemas, concert halls, casinos.
- Betting shops and payday loan businesses.
- Petrol stations and vehicle hire depots.

Why Use Classes Matter
- Flexibility in Property Use:
Some classes, like Class E, allow for greater versatility, making it easier to adapt buildings for different purposes.
- Change of Use Considerations:
Moving from one class to another may require planning permission. However, certain changes are permitted development, meaning they don’t require formal approval. For instance, converting a Class E office into a Class C3 residential dwelling often falls under permitted development.
- Compliance and Regulations:
Adhering to use classes ensures compliance with local planning policies and minimizes the risk of enforcement actions.
