Is my planning application likely to be acceptable?

The Local Planning Authority operates a pre-application advice service through which a Planning Officer provides advice on whether what you wish to build is likely to receive officer support.

You can find out more about this service on our pre-application advice guide.


As general advice, any extension to a mobile home will not be acceptable where it would take the combined resulting structure out of the definition of a caravan.

For the purposes of planning, a caravan is a structure designed or adapted for human habitation which:

  • is composed of not more than 2 sections separately constructed and designed to be assembled on a site by means of bolts, clamps or other devices
  • is, when assembled, physically capable of being moved by road from one place to another (whether by being towed, or by being transported on a motor vehicle or trailer)

The overall combined structure cannot exceed 6.8 metres in width and 20 metres in length. The overall height of living accommodation (measured internally from the floor at the lowest level to the ceiling at the highest level) cannot exceed 3.48 metres.

[Reference: Caravans Site Act 1968, as amended by the Social Landlords (Permissible Additional Purposes) (England) Order 2006 (Definition of Caravan (Amendment) (England) Order 2006)]

Many existing mobile homes within Warfield Park are already twin units (made of 2 sections), so, in most situations it is likely that any enlargements to the mobile home would not be approved, as they would result in the structure comprising at least 3 sections, and would therefore no longer be a caravan.

Other development

Apart from conformity with Caravans legislation, the main matters assessed in planning applications are the potential impacts of the development on:

  • the character of the area
  • the amenities of the occupants of neighbouring properties
  • highway safety

The Local Planning Authority operates a Duty Planning Officer Advice Service. This service can provide general advice on whether your proposal would require planning permission, and how to proceed with making a planning application. Please use the enquiry form below to contact us.

Please note the service does not provide formal assessments or advice on the planning considerations of any potential planning application. Please refer to the pre-application advice service for this.
