Planning permission may be required for a wide variety of development, whether it be new building works or changes in the use of land or buildings.

To assist you to determine whether or not planning permission is required, the Department for Communities and Local Government produce the following Guide:

• Planning - a guide for business

The Planning Portal provides an introductory description of the planning system. It explains how/why to apply for planning permission and much more.

Trafford Council has published a number of Supplementary Planning Guidance documents including information for takeaways, shop fronts and advertisements. The full list is available here:

• Development Control Supplementary Planning Guidance

Most alterations to business premises do need planning permission, including:

• All shop and office extensions;
• Alterations to shop fronts;
• External security shutters or grilles

If you want to change the use of a building or land, you may need planning permission. There are examples below of what types of changes are 'permitted' and which need permission.

Planning permission is not usually needed when both the existing and proposed new uses fall within the same 'Use Class'. The Summary of the Use Classes Order below will give you an idea of which 'class' your use falls into.

It is also possible to change uses between some classes without making an application. The following list gives an indication of the types of use which may fall within each use class.

• Change of Use - Classes Order

Many small businesses and other non residential uses are started by people working in their own homes.

Home-working does not necessarily require planning permission. Permission is not normally required where the use of part of a dwelling-house for business purposes does not change the overall character of the property's use as a single dwelling.

For example, the use by a householder of a room as an office, or child minding business complying with the Department of Health's standard recommended ratios, would be unlikely to mean that the character of the house's use as a single dwelling had ceased and would not normally require planning permission.

Once the business or non-residential use of the property ceases to be ancillary to its use as a single dwelling because, for example, the business has grown and the use of the dwelling for business use has intensified, a material change of use for which planning permission is required is likely to have taken place.

The likelihood of a material change of use taking place may be indicated where the business or non residential use generates visitors, traffic, noise or fumes over and above what might be expected if the property were in use as a single dwelling without any ancillary use.

If you are in doubt you may apply for a Certificate of Lawful Use for the proposed activity, to confirm it is not a change of use and still the lawful use.
