Free Milton Keynes permitted development checker
Could your home project use permitted development? Start with your full address and tell us what you want to build.
You do not need to know the planning route before you start. The check uses available public records and your project details to provide guidance, not a council decision.
About the planning data
Checked against 20.6 million UK planning applications on file across 420 planning authorities. Approval rates from 2,343,419 decisions we classified across 181 councils in England.
What are you checking?
Whether your proposed work may qualify for permitted development, needs a prior approval process or requires a planning application. The property and the complete proposal matter, including earlier additions and conditions on previous permissions.
Read how prior approval works and how planning timescales differ by route.
A postcode locates an area; it cannot establish rights for a particular house. Use your full property address in the checker.

Local checks in Milton Keynes
Check the wording, map and effective date of any Article 4 direction, the property's planning conditions and whether designated land affects the relevant right. A restriction on one type of work does not automatically prohibit every alteration.
Use these resources for Milton Keynes. Confirm the authority for your address if you are close to a boundary or the area has changed council.

Our Milton Keynes archive contains 5,972 classified home project decision records; recent coverage is unavailable. Explore Milton Keynes decisions by project type. These records mix application routes: an approval rate is not a permitted development eligibility score. See the coverage and methodology.
Do you need a permitted development certificate?
A proposed lawful development certificate gives formal confirmation that the development described is lawful. It is optional and is different from prior approval or a planning application. Read our lawful development certificate guide.
The free check does not grant permission or replace a certificate. Check official certificate guidance and the government's explanation of planning routes.
