Planning application fees are set by government. 

A guide to the current fees and a handy calculator is available on the national planning portal. You can make your application via the portal and make your payment at the same time.

The Planning Portal launched the Financial Transaction Service (FTS) in September 2018 and now applies a service charge of £26.83 (+VAT) to some online planning applications that attract a planning fee. Applications with a fee below £60.00 do not incur the service charge.

More information about this is can be found on the Planning Portal website.
