When it comes to architectural planning in the United Kingdom, the Town and Country Planning (Use Classes) Order 1987 (as amended) plays a pivotal role in dictating how properties can be used, thereby influencing the country's urban landscape. This order categorizes uses into various classes, with Class E, introduced in the latest update, being the subject of this in-depth analysis.

Before diving into Class E, let's first understand the broader context. The planning use classes, ranging from A1 to E, were created to simplify the planning process and improve clarity for both local authorities and property owners. Traditionally, classes A to D were largely retail-based, while Class E was originally intended for residential use. However, a significant change in the order in 2020 has resulted in a merging of several uses into the new Class E.

The Emergence of Class E
Under the 2020 order revision, the former Classes A2 (Professional Services), A3 (Food and Drink), B1 (Business), D1 (Non-residential Institutions), and D2 (Assembly and Leisure) have been amalgamated into the new Class E: Commercial, Business and Service.

A key driver behind this change was to stimulate more flexible and adaptable town centres, making it easier for businesses to thrive and adapt to changing circumstances. The new class is designed to accommodate a variety of uses, promoting mixed-use developments and, in turn, diverse and vibrant urban environments.
The Scope of Class E

Class E now encompasses a wide range of uses, including but not limited to, those previously mentioned. It can accommodate restaurants, cafes, shops, banks, gyms, galleries, bars, offices, and even homes above shops, among many others. Its broad remit is intended to encourage adaptive reuse of buildings, reducing the need for extensive redevelopment and making the best use of existing spaces.
To illustrate the scope of Class E, consider a high street with a variety of properties. Under the new class, a former office could now house a pub, a hairdresser's could relocate into a retail unit, or a restaurant could expand into space formerly occupied by a bank. This flexibility fosters diverse and dynamic urban landscapes, benefiting both businesses and communities.
Reservation of Prior Permission and Restrictions

While Class E offers considerable flexibility, certain uses are 'permitted development rights' (PDR) and may require a change of use application. This includes, for example, the conversion of shops (Class E) to homes (Class C3). reservation of prior permission also applies to certain uses, meaning while they're included in Class E, they may need specific permission.
Additionally, Class E is subject to restrictions. Uses like betting shops, payday loan providers, and amusement arcades have been explicitly excluded. Local authorities also retain the power to issue article 4 directions, removing PDR for certain uses or areas, further refining the controls over diverse town centres.
Impact on Planning and Development

The introduction of Class E has significantly altered the UK's planning landscape. It simplifies the use class system, potentially reducing the need for planning applications and encouraging more sustainable and efficient use of space. This is particularly beneficial in towns and city centres, where mothballed units and vacant properties can parish, contributing to a more thriving commercial environment.
However, the change also presents challenges. The broad nature of Class E may lead to some uses being 'backdoor' permissions, with potential negative impacts on the character of an area. For example, fears include a rise in hot food takeaways in residential areas, ])
The Act also places a greater responsibility on applicants and local authorities to ensure that new uses are appropriate and beneficial to their surroundings. Robust planning policies, supported by detailed Local Plans and Neighbourhood Plans, will be crucial in guiding Class E developments, ensuring they contribute positively to their communities.




















The Role of Local Plans and Policy
In light of Class E's broad remit, local planning authorities have a vital role in shaping its impact. Through the preparation of Local Plans, they can determine where Class E uses are appropriate and which are not. They can do this by setting clear policies, identifying suitable locations for various uses, and ensuring that Class E development aligns with the needs and aspirations of their area.
For instance, a plan might indicate that whilst Class E uses are welcome in the town centre, they are not suitable in residential areas. Alternatively, it could specify that gyms are only allowed in Class E units above a certain size or where certain parking criteria are met. This policy-making power enables local authorities to manage and control the impact of Class E, ensuring it brings benefits rather than challenges to their towns and cities.
As we navigate this new landscape, it's clear that Class E, with its broad scope and flexible rules, offers much-needed agility in the UK's planning system. However, it's also evident that understanding and implementing its nuances will be key to unlocking the benefits it promises. Through a blend of robust policy-making and careful application, the full potential of Class E can be harnessed - driving sustainable, resilient and distinctive places for all."
