Householder extensions and small-scale business development

Householder extensions

The planning portal helps establish whether or not you need planning permission for your development. If you are unsure, our team will be able to help you interpret the rules.

If you don't need planning permission, we can provide you with a certificate of lawful development to confirm this. This confirms that planning permission is not necessary for your proposal and proves very helpful should you come to sell your property. The cost is £103.00. Please refer to our main planning webpage regarding how to apply.

If planning permission is necessary for your extension and you'd like to discuss your proposal further, our duty planner is available via a prebooked telephone meeting. There is a £50 fee for a 15 minute telephone appointment (please book in advance).

To book an appointment you must submit the following information, in advance to planning@cheltenham.gov.uk, and you will be contacted to arrange an appointment.

Minimum required documents/information:

  • name, site address, email address and telephone number
  • site location plan
  • site photographs (front, rear, side and garden/neighbouring property views, external and internal where relevant)
  • description of proposed development (including location of extension; if its single or two storey and the metric dimensions)
  • elevation drawings (sketch drawings acceptable)
  • floor plans (sketch plans acceptable)

Additional  information which would enable a more comprehensive response and discussion with the Duty Officer:

  • materials details
  • applicant’s interest in the land
  • neighbouring development/extensions which may impact on proposals
  • site context (street scene elevations or street photographs)
  • anything else relevant e.g. trees, parking/highway matters, flood/drainage

During your appointment, we will provide valuable advice on how likely your proposals are to gain planning permission, how you can best improve these chances (if necessary) and what information we need to register your application. This can save you time and money when it comes to submitting your plans.

Small-scale business proposals

A telephone appointment with the duty officer is also a suitable starting point should you wish to discuss commerial changes of use where no new floor space is being created. Please see above for how to arrange a telephone appointment with our duty planner.

The more information that you can provide, the more productive the meeting will be.

Our team will advise on how likely your proposals are to gain planning permission, how you can best improve these chances (if necessary) and what information we need to register your application.

Please note: Our duty officer system is not appropriate for discussing medium to large-scale commercial development or proposals for new houses. Pre-application advice is most suitable for these types of discussions. Please see below for more information on our pre-application services.
