Planning Permission for Businesses in England: A Practical Guide

Do you need planning permission?

Planning permission is required for development, which includes building operations, engineering works, and material changes of use of land or buildings. However, many common business activities are either permitted development or fall within the same use class and therefore do not need permission.

The key question is whether you are making a material change of use. A change is material if it significantly alters how the property is used in planning terms. The Town and Country Planning (Use Classes) Order 1987 (amended in 2020) groups similar uses together — changing within a class does not require permission.

Use Class E: Commercial, Business and Service

The 2020 Use Class Order reforms consolidated many former classes into the new Class E. This single class now includes:

• Retail shops (formerly A1)
• Restaurants and cafes (formerly A3)
• Financial and professional services (formerly A2)
• Offices (formerly B1a)
• Light industrial (formerly B1c)
• Research and development (formerly B1b)
• Gyms, health centres, and indoor sports facilities
• Creches and day nurseries
• Medical and health services (non-residential)

Key benefit: You can freely change between any Class E uses — for example, converting an office to a shop, or a restaurant to a gym — without needing planning permission for the change of use itself. You may still need permission for building works or signage changes.

Notable exclusions from Class E: pubs and hot food takeaways (sui generis), hotels (Class C1), care homes (Class C2), and heavy industry (Class B2).

Permitted development rights

Permitted development (PD) rights allow certain works and changes without a full planning application. For businesses, common PD rights include:

• Minor extensions — extensions to industrial or warehouse buildings up to 50% of the original building footprint (subject to conditions)
• Temporary structures — some temporary buildings for up to 28 days/year
• Signage — certain types of business signs are permitted under the Advertisement Regulations
• Telecommunications equipment — antennas and masts subject to size limits

PD rights can be restricted by Article 4 Directions, which local councils can use to remove specific permitted development rights in sensitive areas (e.g. conservation areas, town centres).

When you DO need planning permission

You will need full planning permission for:

• New buildings and significant extensions (those exceeding permitted development limits)
• Changes of use outside Class E — for example, converting a shop (Class E) to a pub (sui generis), or offices to a hotel (Class C1)
• Changes of use into Class E from a non-E class — for example, converting a pub back to a shop
• Works to listed buildings (also require listed building consent)
• Development in conservation areas that would affect the character
• Any development exceeding PD limits

Prior approval: a lighter-touch process

Some conversions can be done via Prior Approval rather than full planning permission. Prior approval is quicker and cheaper — the council can only consider specific matters, not general planning policy. Key prior approval routes for businesses:

• Class MA — commercial, business and service (Class E) to residential (Class C3). Allows conversion of commercial buildings to homes. Conditions: building must have been in Class E use for 2 years; vacant for 3 months immediately before application; minimum 1,500 sqm gross floor area if in a protected area.
• Class G — retail (Class E) to mixed use (retail + residential above)
• Class Q — agricultural buildings to residential

The council must decide within 8 weeks (or 56 days). If it fails to decide in time, prior approval is deemed granted.

The planning application process

1. Pre-application advice — most councils offer paid pre-application advice. Strongly recommended for complex proposals; gives early feedback and reduces refusal risk.
2. Submission — applications are submitted via the Planning Portal. You will need site plans, block plans, and supporting documents.
3. Validation— the council checks your application is complete. If invalid, they will request additional information (the clock doesn't start until validation).
4. Public consultation — neighbours and statutory consultees (e.g. Environment Agency, Highways) have 21 days to comment.
5. Decision — the planning officer either makes a delegated decision or refers it to the planning committee. Decision time: 8 weeks for minor applications, 13 weeks for major ones.
6. Conditions — permission may be granted subject to conditions. Some conditions must be discharged before work starts.

Planning application costs in England

These are statutory fees paid to the council. Agent/architect fees and pre-application advice are additional costs.

Planning enforcement

If you carry out development without planning permission, the council can take enforcement action:

• Planning Contravention Notice (PCN) — requests information about the alleged breach
• Enforcement Notice — requires you to remedy the breach within a set period; you can appeal to the Planning Inspectorate
• Stop Notice — immediate halt to operations (rarely used)
• Injunction — court order for serious or repeated breaches

Time limits for enforcement:

• 4 years — for operational development (buildings) and change of use to a dwelling
• 10 years — for all other breaches of planning control, including change of use

After these periods, the development becomes lawful and you can apply for a Certificate of Lawful Use.

Planning appeals

If your application is refused, or conditions are unreasonable, you can appeal to the Planning Inspectorate:

• Written representations — fastest method; suitable for straightforward cases; typically decided in 24 weeks
• Hearings — informal discussion before an inspector; suitable for moderately complex cases
• Public inquiries — formal, quasi-judicial; suitable for complex, major, or controversial cases
• Costs awards — either party can apply for an award of costs if the other has behaved unreasonably

You must appeal within 6 months of the decision (12 weeks for householder appeals).
