Guide: Prior Approval in the Green Belt
The Green Belt exists to prevent urban sprawl and protect the openness of land around towns and cities. Therefore Green Belt development is highly sensitive, as national policy aims to keep the land “permanently open” and considers inappropriate development harmful.
In some cases, permitted development rights with a prior‑approval process can provide a simpler alternative to a full planning application.
How Prior Approval Works
Certain types of development are allowed automatically under the Town and Country Planning (General Permitted Development Order 2015). Some of these permitted rights need a “prior-approval” check. This means you must ask the Local Planning Authority to look only at a short list of issues set out in the relevant part of the GPDO.
The authority is not allowed to assess anything outside that list. For example, unless the GPDO class specifically mentions Green Belt matters, they cannot refuse a prior-approval application because of wider Green Belt policy. If the proposal meets the requirements in the legislation, it is treated as permitted development.
When Prior Approval Can Apply in the Green Belt
Prior‑approval routes are limited and may apply to:
Change of use of specific types of building (for example, agricultural buildings changing to dwellings under Class Q, or commercial space changing to residential under Class MA)
Small extensions that fall within the size and height limits set out in the GPDO
Temporary structures or temporary uses that are allowed for set periods
Even with prior‑approval, proposals that harm openness can still be classed as inappropriate, meaning “very special circumstances” would be needed.
Key Points to Consider
Check LPA Restrictions. Permitted development rights can be removed or restricted through Article 4 directions.
Respect Green Belt Principles. Any development that undermines openness may be refused.
Follow the Process. Submit the correct form, wait for the LPA’s decision or statutory period, and carry out the works according to approved or submitted details.
How We Can Help
At PAA Ltd we specialise in Green Belt development and prior‑approval routes. We can:

Conclusion
Green Belt development is challenging, but a prior‑approval route can offer a viable alternative to full planning permission in certain circumstances. By carefully checking rights, respecting Green Belt policy, and following the process, you can maximise your project’s chances of success.
