Expanding Schools Without Full Planning Permission
Growing pupil numbers, the need for new SEN spaces, and increased wraparound care have left many schools and nurseries looking for quick, affordable ways to expand. Modular classrooms and lightweight extensions have become popular, but one crucial question is often overlooked:
Do schools actually have Permitted Development Rights?
The short answer is yes — but the detail is where things become complicated...

What Are Permitted Development Rights?
Permitted Development (PD) Rights are a set of national planning rules that allow certain types of building work or changes of use without needing a full planning application. They’re set out in the Town and Country Planning (General Permitted Development) (England) Order 2015, often abbreviated to “the GPDO.”
For education providers, the relevant section is Part 7, Class M — this covers schools, colleges, universities, and hospitals. These rights were introduced to make it easier for institutions to make small-scale improvements to their premises without a lengthy application process.

Do schools have PD Rights?
Yes, most schools and nurseries benefit from Permitted Development Rights, but they’re not universal and not unlimited. Under Class M, the following types of work are typically allowed:

Do schools have PD Rights? What Is Allowed Under Educational PD Rights?
In broad terms, schools can undertake modest improvements to existing facilities without full planning permission, provided the work stays within Class M limits.
This means that installing a small modular classroom, relocating a temporary building, or creating additional outdoor learning space could all qualify — as long as the development remains within scale and height thresholds and is genuinely required for the educational use of the site.
Temporary buildings are also permitted, but it’s important to remember that “temporary” does not mean “automatically allowed.” In some cases, the Local Planning Authority (LPA) may still require prior approval or evidence of lawful use.

Common Pitfalls
Some schools assume that modular buildings are always classed as “temporary” and therefore exempt — but if the new classroom exceeds the permitted footprint or height, PD no longer applies.
It’s also easy to overlook curtilage boundaries, which define the area around the main school buildings. Extending beyond this, even slightly, can invalidate PD Rights altogether.
Another frequent issue is forgetting that Building Control approval still applies, even when planning permission is not required.

Example: When PD Rights Don't Apply
An Oxfordshire primary school recently installed a modular SEN unit under the belief it was permitted development. However, the height exceeded 5m and the footprint surpassed 25% of the existing building. Retrospective planning permission was required, which delayed occupation and increased costs.

Final Words
Permitted Development Rights can be extremely useful, but their application is site-specific.
Before starting work, it’s often best to apply for a Certificate of Lawfulness from your local authority. This confirms whether your proposed development genuinely falls under PD and protects against future enforcement.
Educational PD Rights are a powerful tool when used correctly — enabling schools and nurseries to expand quickly to meet local need.
But the rules are more nuanced than they appear, and misinterpreting them can lead to expensive delays.
Before ordering that modular classroom or playground shelter, consider professional planning advice.
A short consultation with Mark Doodes Planning can confirm whether your project qualifies under PD or requires formal permission.
