What Does “Change of Use” Mean?
In planning law, “change of use” refers to altering the purpose for which a property is used. Properties are categorised into different “use classes” under the Town and Country Planning (Use Classes) Order 1987 (as amended). A change of use occurs when a property moves from one class to another.
Residential Use Classes:
- Class C3: Dwelling houses (e.g. family homes, flats)
- Class C4: Houses in multiple occupation (HMOs)
Common Commercial Use Classes:
- Class E: Commercial, business and service uses (e.g. shops, offices, restaurants)
- Class B2: General industrial
- Class B8: Storage or distribution
- Sui generis: Uses not falling within a specific class (e.g. pubs, nightclubs, betting shops)
Changing from Class C3 to Class E or another commercial class typically requires planning permission, unless permitted development rights apply.
Planning Permission Requirements
In most cases, changing a property from residential to commercial use requires planning permission from the local planning authority. This is because the change may affect the character of the area, traffic levels, noise, and other environmental factors.
When Planning Permission Is Required:
- The proposed commercial use falls outside permitted development rights
- The change involves structural alterations or extensions
- The property is in a conservation area or subject to Article 4 Directions
- The new use may impact neighbours or local amenities
When Planning Permission May Not Be Required:
- The change falls within permitted development rights
- The use is ancillary to the existing residential use (e.g. a home office)
- Temporary commercial use under certain conditions
Each case must be assessed individually, and legal advice is essential to determine whether permission is needed.
Permitted Development Rights
Permitted development rights allow certain changes of use without the need for full planning permission. These rights are subject to conditions and limitations and may require prior approval from the local authority.
Examples of Permitted Development:
- Conversion of a dwelling to a small office (Class E) in some circumstances
- Use of part of a residential property for business purposes (e.g. childminding, consulting)
- Temporary change of use for up to 3 years under Class D of the General Permitted Development Order
Limitations:
- Not available in conservation areas, national parks, or areas subject to Article 4 Directions
- May be restricted by the property’s planning history or conditions attached to previous permissions
- Prior approval may be required for matters such as transport, noise, and impact on the community
Permitted development rights are complex and subject to frequent changes. Professional advice is recommended before relying on them.
Title and Leasehold Restrictions
In addition to planning law, property owners must consider any legal restrictions in the title deeds or lease agreements.
Freehold Properties:
- Check for restrictive covenants prohibiting commercial use
- Covenants may be enforceable by neighbouring owners or management companies
- Legal advice may be needed to vary or remove covenants
Leasehold Properties:
- Review the lease for use restrictions
- Most residential leases prohibit commercial use or require landlord consent
- Breach of lease terms may result in enforcement action or forfeiture
Changing the use of a leasehold property without proper authority can have serious legal consequences.
Building Regulations and Compliance
Any physical alterations to the property to accommodate commercial use must comply with building regulations. These regulations cover:
- Structural safety
- Fire safety
- Accessibility
- Ventilation and sanitation
- Energy efficiency
A change of use may trigger additional requirements, such as installing fire doors, upgrading insulation, or providing disabled access. Building control approval is separate from planning permission and must be obtained before work begins.
Business Rates and Council Tax
Changing a property from residential to commercial use affects its liability for local taxation.
Residential Properties:
- Subject to council tax
Commercial Properties:
- Subject to business rates
Once the change of use is approved and implemented, the Valuation Office Agency will reassess the property and assign a rateable value. This may result in higher annual costs, although reliefs may be available for small businesses or vacant premises.
Practical Considerations
Changing a property’s use is not just a legal exercise—it has practical implications for the owner and occupiers.
Access and Parking:
- Commercial use may require additional parking or access arrangements
- Local authorities may impose conditions to mitigate traffic impact
Impact on Neighbours:
- Noise, footfall, and operating hours may affect residential neighbours
- Objections during the planning process can delay or prevent approval
Insurance:
- Residential insurance policies may not cover commercial activities
- Specialist commercial property insurance may be required
Finance and Mortgages:
- Residential mortgages may prohibit commercial use
- Lenders may require refinancing or consent before change of use
