What Is Class MA? A Guide

March 31, 2025

Class MA Permitted Development Rights permit the conversion of buildings such as restaurants, offices, shops, nurseries, cafes, leisure facilities, and health services (Class E properties) into homes.

When you consider that the ‘UK lost 37 shops a day in 2024’, it’s evident that Class MA has the potential to revitalise struggling town centres and provide more homes for residents in the surrounding area whilst offering exciting development opportunities. 

Coming into force in 2021, Class MA has since seen updates that came into effect in 2024. But first, let’s take a look at what Class MA is.

In short, Class MA allows for the conversion of commercial, business, and service buildings (Class E) to residential dwellings (Class C) without the need for planning permission.

However, there are many considerations and changes that have come into effect relating to Class MA that developers should be aware of, all of which we’re going to cover in this guide.

Class MA 2024 Changes

Changes relating to Class MA came into effect in March 2024 and extend to both England and Wales.

So, what do these changes actually mean for Class MA opportunities? It mainly comes down to two main points.

Previously, Class MA opportunities needed to be less than 1500sqm. What’s more, the building had to be vacant for a minimum of 3 months.

That said, these changes brought in in March 2024 mean there’s no longer a limit to the floor space that can be converted under Class MA, and the building no longer needs to have been vacant for 3 months.

These changes will open up more opportunities for developers to convert larger buildings on the high streets, as well as buildings that were only partially converted.

When you consider that the ‘UK lost 37 shops a day in 2024’, it’s evident that Class MA has the potential to revitalise struggling town centres and provide more homes for residents in the surrounding area whilst offering exciting development opportunities. 

Class MA Permitted Development Opportunities: Important Considerations

When analysing Class MA development opportunities, there are many considerations to bear in mind that include but are not limited to:

1. The Property Must Have Been Use Class E for 2 Years

The first factor to consider when looking for Class MA development opportunities is that the property needs to have been Use Class E for a minimum of 2 years.

In other words, it must have been a shop or an office, for instance, for at least 2 years before the application was made.

2. The Development Must Be Completed In 3 Years

Another factor to consider is that development must be completed within 3 years of the prior approval date.

What’s more, the Local Planning Authority (LPA) must be notified when the development has been finished.

3. Some Buildings Can’t Be Converted

Development is not always permitted by Class MA, and some buildings can’t be converted.

Just a few examples of this include if the building is within a National Park, a World Heritage Site, Sites of Special Scientific Interest (SSSIs), an Area of Outstanding Natural Beauty, and if the building is Listed.

4. Prior Approval Is Required

Although many Class MA opportunities don’t require full planning permission, Prior Approval is still very much a requirement.

As such, developers will need to submit a Prior Approval application to the LPA.

Prior Approval requirements can include assessments relating to noise considerations, flood vulnerability, and window proposals, amongst others.

5. An Additional Planning Application Might Be Required

Depending on the development opportunity, you may still need to submit an additional planning application.

For instance, if your building requires additional doors and windows, then a planning application will more often than not be required to make these changes.

That said, it’s key to approach Class MA opportunities on a case-by-case basis and familiarise yourself with the unique requirements of each development.

Class MA can help breathe new life into town centres whilst providing more homes in the UK. That said, the considerations above remain essential when identifying potential development land.
