What Application for Changes of Use Consider
Planning authorities assess whether the proposed new use is appropriate for the location and whether it would result in unacceptable impacts.
- The planning use class of the existing and proposed use
- The character of the area and compatibility with surrounding uses
- Traffic, access, servicing, and parking implications
- Noise, disturbance, and impact on neighbouring amenity
- Design, appearance, and any external alterations required
- Impact on town centres, employment areas, or protected uses
- Environmental health considerations including contamination and ventilation
- Heritage, conservation area, or listed building constraints where relevant
- Whether the change can proceed under permitted development or requires full permission
When this service is appropriate
Use this service when you are proposing to use a building or land for a purpose different from its lawful planning use. This is particularly relevant:
- For converting commercial premises into residential units
- For changing retail or office premises into alternative business uses
- For converting agricultural buildings into dwellings
- For changes between different business or community uses
- Where external alterations are required alongside the use change
- Where you are uncertain whether the change can proceed under Prior Approval or requires full planning permission
Early advice avoids pursuing the wrong route and reduces the risk of refusal.
Frequently Asked Questions
What is a change of use in planning terms?
A change of use occurs when a building or land moves from one planning use class to another as defined in planning legislation. Even if no physical works are proposed, planning permission may still be required.
Can some changes of use happen without planning permission?
Yes. Some changes of use are allowed under permitted development or Prior Approval provisions. Whether this applies depends on the existing lawful use, the proposed use, and specific limitations in the legislation.
How do I know what the lawful use of my building is?
The lawful use is determined by planning history and how the property has been used over time. This is not always obvious from how a building looks or is currently occupied. We can review planning records to confirm this.
Does a change of use require building works?
Not necessarily. Some changes of use involve no external alterations, but others may require new access, ventilation, shopfront changes, or internal layout adjustments that have planning implications.
Will the council consider the impact on neighbours?
Yes. Noise, activity levels, hours of operation, and general disturbance are key considerations, particularly when changing from a quieter to a more intensive use.
Can agricultural buildings be converted to residential use?
In many cases, yes. There are Prior Approval routes that allow the conversion of agricultural buildings into dwellings, subject to meeting specific criteria relating to the condition of the building, access, and environmental considerations.
