Manchester Commercial Guide
Do I Need Planning Permission for a Fit Out in Manchester?
Short answer: sometimes yes, often no. It depends entirely on what you are changing. A fit out that keeps the same use and the same shopfront usually needs no planning permission at all. A fit out that changes the use, alters the shopfront, or adds new signage often does. This guide explains exactly where the line sits, so you know what applies to your Manchester premises before you commit to a lease or a contractor.
First, What Counts as a Fit Out?
A commercial fit out is the work that turns an empty or dated commercial space into one ready to trade from. It usually covers partitions, flooring, ceilings, lighting, electrics, data, heating and ventilation, decoration, joinery, and the shopfront or entrance.
The key thing to understand is that planning permission is not triggered by the fit out work itself. It is triggered by three specific things: a change of use, an external alteration, or new signage. Internal works on their own almost never need planning permission. Get clear on which of the three you are doing, and the answer becomes simple.

Are you changing the use of the building?
This is the big one. Every commercial property in England has a planning "use class". Whether you need permission depends on whether your new use stays in the same class as the old one.
Since September 2020, most high street commercial uses sit inside one broad class called Class E. This covers shops, offices, cafes and restaurants, financial and professional services, gyms, clinics, and more. Movement from one use to another within Class E is not classed as development, so it does not require planning permission.
In plain terms: turning a former shop into an office, a cafe into a clinic, or an office into a gym usually needs no planning permission for the change of use itself, because all of those sit within Class E.
The exception is "sui generis" uses, which sit in a class of their own. Pubs, hot food takeaways, nightclubs, cinemas, casinos, and petrol stations are all sui generis. Changing to or from one of these almost always needs full planning permission, because you are crossing a use class boundary with no permitted development right covering it.
Are you altering the shopfront or the exterior?
Internal fit out works do not need planning permission. The moment you touch the outside, the rules change.
You will normally need planning permission for any alteration that materially changes the external appearance of the building. Replacing the shopfront, changing the entrance doors, installing new windows, fitting roller shutters, or adding an awning are the common triggers.
Minor repairs and like for like replacement usually do not need permission. Replacing a damaged panel with an identical one is repair. Installing a brand new shopfront in a different style is alteration, and that needs consent.
Installing external plant such as air conditioning units, extraction systems, or ventilation can also require planning permission, particularly if the equipment is visible from the street or changes the appearance of the building.
Are you putting up new signage?
Signage is controlled separately from planning permission, under the Town and Country Planning (Control of Advertisements) Regulations 2007. This is called advertisement consent.
Some signs have what is called "deemed consent", meaning they can be displayed without a formal application as long as they meet size, position, and illumination conditions. Many traditional, modest, non illuminated fascia signs fall under deemed consent.
Other signs need express advertisement consent from the council before they go up. Nearly all illuminated signs require permission. Large signs, projecting signs, and signs in sensitive locations often need consent too.
This matters because displaying an advert without the consent it requires is a criminal offence, and the council can require its removal. It is not a risk worth taking to save a few weeks.
Conservation Areas and Listed Buildings Change Everything
Manchester has a number of conservation areas, and many of its commercial buildings, particularly in the city centre, the Northern Quarter, and Castlefield, are listed. If your premises is in a conservation area or is a listed building, the relaxed rules above no longer apply.
If your premises is in a conservation area
Permitted development rights are reduced. Shopfront alterations and signage that might be acceptable elsewhere will face stricter design control. Councils expect traditional materials and sympathetic designs, and many have published shopfront design guides setting out what they will and will not accept.
If your premises is a listed building
This is the strictest position. Listed Building Consent is required for any alteration that affects the character of the building, inside or out. That includes internal fit out works that would not need any permission in an ordinary building. Removing or altering internal features, changing the shopfront, and even signage all need Listed Building Consent on a listed property. Carrying out unauthorised work to a listed building is a criminal offence.
You can check whether your premises is listed or in a conservation area through Manchester City Council's planning pages before you sign anything.
Planning permission is separate from Building Regulations. Even a purely internal fit out that needs no planning permission will almost always need to comply with Building Regulations, covering fire safety, means of escape, electrical safety, ventilation, accessibility, and structural work. Building Regulations apply to the work regardless of whether planning permission does.
Fit Outs That Usually Need No Planning Permission
To make it concrete, here are common Manchester fit out scenarios that typically need no planning permission, as long as the building is not listed and not in a conservation area:
- Fitting out an empty office for a new tenant, same use, no external change
- Refitting a shop interior with new partitions, flooring, lighting, and decoration
- Converting an office into a clinic, or a shop into a cafe, where both uses sit within Class E
- Internal reconfiguration, new ceilings, new electrics and data, new heating
- Like for like repair of an existing shopfront
- A modest, non illuminated fascia sign that meets the deemed consent conditions
Fit Outs That Usually Do Need Permission
And here are the scenarios that typically do need planning permission, advertisement consent, or both:
- Changing to or from a pub, hot food takeaway, or other sui generis use
- Installing a new shopfront in a different design or materials
- Adding or replacing roller shutters visible from the street
- Fitting external air conditioning, extraction, or ventilation visible from the street
- Any illuminated sign
- Large or projecting signs that fall outside deemed consent
- Any external alteration or signage on a building in a conservation area
- Any alteration, internal or external, to a listed building
"The most expensive fit out mistakes happen when a tenant signs a lease assuming a use is allowed, then finds out it needs planning permission that may not be granted."
Check Before You Sign the Lease
The single most important piece of advice in this guide: confirm the planning position before you commit to a lease, not after.
If your business needs a specific use, a specific shopfront, or specific signage, find out whether the premises can lawfully provide it before you sign. A lease commits you to rent. It does not guarantee the council will approve your intended use or alterations. Tenants who discover the gap after signing can be left paying rent on premises they cannot trade from as planned.
How to check the planning position
- Confirm the current lawful use class. Ask the landlord or agent, and check past planning history on the Manchester City Council planning portal.
- Identify the use class you need and whether it matches or crosses a class boundary.
- Check conservation area and listed status for the specific address.
- Consider pre application advice. Manchester City Council, like most authorities, offers a pre application advice service for a fee. It gives you a written response confirming what consents your project needs. For a commercial fit out, this is usually money well spent.

Do I need planning permission to fit out an office in Manchester?
For a standard internal office fit out, where the building stays in office use and the exterior is not altered, no planning permission is required. The work itself, partitions, ceilings, flooring, lighting, electrics, and decoration, is internal and not classed as development. You will still need to comply with Building Regulations. The exception is if the building is listed, in which case Listed Building Consent is required even for internal works.
Can I change a shop into a cafe without planning permission?
In most cases yes. Since September 2020, both shops and cafes sit within Use Class E, and movement between uses within the same class does not require planning permission. However, you should check whether the cafe involves elements that can trigger separate applications, such as late opening hours, hot food, or external seating. If the premises is listed or in a conservation area, additional consents may apply. Always confirm the position before signing a lease.
Do I need permission to put up a sign for my business?
It depends on the sign. Signage is controlled under the Town and Country Planning (Control of Advertisements) Regulations 2007. Some signs have deemed consent and can be displayed without a formal application if they meet size, position, and illumination conditions. Other signs, including nearly all illuminated signs, large signs, and projecting signs, require express advertisement consent from the council. Displaying a sign without the consent it requires is a criminal offence, so check before installation.
What is a sui generis use?
Sui generis means "in a class of its own". These are uses that do not fit into any standard use class, including pubs, hot food takeaways, nightclubs, cinemas, casinos, and petrol stations. Because they sit outside the broad Class E, changing to or from a sui generis use almost always requires full planning permission. If your fit out involves opening a takeaway or a pub, expect to need a planning application.
Do I need planning permission to install air conditioning for my fit out?
Internal air conditioning generally does not need planning permission. External plant, such as condenser units, extraction systems, or ventilation visible from the street, can require planning permission, particularly if it materially changes the appearance of the building or is in a conservation area. Very small, discreet equipment that is not visible from the street may not need permission. Check the specific position for your premises before installation.
How long does planning permission or advertisement consent take?
A standard planning application is determined within 8 weeks, though shopfront and signage applications can take 8 to 12 weeks in practice. Pre application advice, if you choose to use it, adds time at the front but reduces the risk of refusal. Build the consent timeline into your fit out programme from the start. Committing a contractor and a lease start date before consents are secured is a common and costly mistake.
What happens if I do a fit out without the permission I needed?
The council can take enforcement action. For unauthorised use or external alterations, that can mean an enforcement notice requiring you to reverse the work or stop the use. For signage displayed without consent, it is a criminal offence and the council can require removal and issue fines. For unauthorised work to a listed building, it is also a criminal offence with potentially serious penalties. The cost of putting things right after the fact is almost always far higher than getting the consents in advance.
Who is responsible for getting planning permission, the landlord or the tenant?
Usually the tenant, as the party carrying out the fit out and benefiting from the use. However, the lease will often require the landlord's consent for alterations as well, which is separate from planning permission. You typically need both: the landlord's consent under the lease, and any planning permission or advertisement consent from the council. Check the lease terms and the planning position together before committing.
If You Take One Thing From This Guide
It is this: the fit out work itself rarely needs planning permission, but the use, the shopfront, and the signage often do. And all three need to be checked before you sign the lease, not after.
