Building control fees

If you need a quote
If your work does not fall into the standard charges tables or falls under 3 or more categories, you can request a building control quote.
About the payment
A building control plan fee is different from a planning application plan charge. Make sure you contact the correct department when paying your fee.
If your work falls under more than one category, each fee is payable on submission.
Any reduction that applies because the different parts of work are carried out at the same time will be applied to the inspection fee after commencement of the work.
All building notice fees are paid on submission.
In most cases, an inspection charge is payable after you start work and covers the:
- a site inspection from our team
- a completion certificate
We invoice this after the first inspection has been carried out.
The inspection charge can also be paid with the plan charge when you submit the application, and where possible we will encourage this.
Payment can also be made by credit or debit card following receipt of your application. You will need to quote the:
- card number
- expiry date
- security number
- the house number and the postcode of where the card is registered
We do not accept American Express.
All cheques for Building Control applications must be made payable to ‘Buckinghamshire Council’ regardless of the site address.
(cheques made out to a former District Council will be returned)
Online applications can be paid via WebPay.
