Cost of planning permission
by

Thinking of adding an extension to your property to enhance the value? Perhaps you’re looking to make use of a plot of land to build your home from scratch? Getting planning permission is essential for new buildings and structural changes to existing properties. We recommend checking with your local council before hiring a professional to help with the job. But how much can you expect to pay in planning permission costs?

While you may be aware of planning application fees, it’s easy to underestimate the bill.

The last thing you want is for your project to go over budget before you’ve even started work. To give you a head start, we’ve put together the following guide to planning permission fees.

What is planning permission?

Planning permission is, as the name suggests, the application you have to make to your local council ahead of building on land or making structural changes to the property. The purpose this is to ensure your proposed construction works comply with building regulations and won’t obstruct neighbours’ view or right of way. When making a planning application, you will need to submit supporting documentation and pay a fee to the council.

Outline planning permission costs

The cost of submitting a planning application varies across the UK, but is currently £462 for a full application for a new single dwelling in England. For those looking to add an extension or loft conversion to their homes, an application in England for an extension currently costs £206.  In Wales, the cost of a typical householder application is £190.

Retrospective planning fees

If you have already started on construction and haven’t obtained planning permission, don’t panic. Your local authority will simply ask that you submit a retrospective planning application for the work that has been carried out so far.

Planning permission won’t automatically be granted, and the application will be subject to the same criteria as a standard planning application. Costs for retrospective planning permission are the same as those for advance permission: £462 for a new single dwelling and £206 for an extension in England.

If the application is refused, you will be required to put things back as they were unless you appeal the decision and it is overturned. To appeal a planning decision, you will need to send a copy of your appeal, including all the supporting documents, to your local planning authority.

Do I need planning permission?

Looking to add more space to your home or make use of land? There’s a good chance you will need to obtain planning permission if you want to:

  • Build a new home
  • Make major structural changes to your property
  • Change the use of your building

If in doubt, it’s always best to check with your local planning authority.

FAQs

Is planning permission free?

Sadly, no. Obtaining planning permission will require a fee to be paid upfront. For an extension, you can expect to pay £206 to your local council. For a new build, it’s £462.

What size can you build without planning permission?

Thanks to the recent relaxation of development rules, homeowners can build an extension of up to six metres without planning permission. If you have a detached house, the limit is eight metres.

retrospective planning permission costWhat drawings do I need for planning permission?

When submitting your application to the local council, you will need to provide:

  • The necessary plans of the site
  • The required supporting documentation
  • The completed form
  • The correct fee.

For most projects, you will need an architectural drawing of the existing floor plan as well as your proposed floor plan post-development. Read up on the average prices of architectural drawings via our dedicated cost guide.
