Changes you can make without consent

In many cases a change of use of a building does not need planning permission. This normally applies when the existing use and the proposed new use are within the same class, or count as ‘permitted development’. For example, a food shop could be changed to a shoe shop without permission as these uses fall within the same ‘class’. Or a restaurant could be changed to a shop or an estate agency as the Use Class Order permits this as ‘permitted development’. If this all sounds too good to be true, you’re right – there’s a sting in the tail. If you need to carry out any external building work to the building it’s likely to require planning permission. And of course most building work will also need to comply with the Building Regulations. So an application will need to be made.

New measures

Additional change of use Permitted Development Rights were introduced in October 2013 (originally for 3 years but now permanent):- OFFICES (B1a) can change to C3 residential (subject to prior approval of flood risk, highways/transport and contamination issues).  From 2016 this also applies to conversions of light industrial buildings and launderettes, and the rules were relaxed on demolition of office buildings. Agricultural buildings under 500 sq m. can change to A1, A2, A3, B1, B8, C1 or D2. But ‘prior approval’ is required for buildings of 150 to 500 m2 (to assess flood risk, noise and highways impacts etc). B1, C1, C2, C2A and D2 uses can change use permanently to a state-funded school (subject to prior approval of noise and highways/transport impacts). Temporary change of use A1, A2, A3, A4, A5, B1, D1 and D2 uses are permitted to change use for a period of up two years to A1, A2, A3 and B1 uses.

Changing from one type of shop to another

A planning application is often not required to change from one type of shop to another. However, permission will be required to change from a retail shop to any of the following examples:

  1. A shop selling food and drink for the consumption on the premises, or hot food for the consumption off the premises (cafés, restaurants, take-aways, bars)
  2. An office
  3. An amusement arcade
  4. A launderette
  5. Motor vehicle showroom
  6. A taxi business
  7. Residential

Opening a café, bar, restaurant or take-away

If you are considering opening a café, restaurant or bar you will need to comply with several different requirements as follows: The following classes of uses

  • Class A3: Restaurants and cafés
  • Class A4: Drinking establishments
  • Class A5: Hot food take-aways

Sometimes you will see Estate Agents advertising premises with A3, A4 or A5 use. You should always check with Planning (Development Control) that the property has the necessary planning permission, and that there are no conditions attached to the permission that would prevent you from operating in the way that you wish. For example, there may be a condition restricting the opening hours, prohibiting a take away service or preventing a café being used as a bar or pub.
