Replacing a shopfront is one of the few shop improvements where the council often does have a say. Whether you need planning permission depends on what you are changing, where your premises sits in Birmingham, and whether the building is listed or in a conservation area. Here is how it actually works, in plain terms.
Like-for-like repairs generally do not need planning permission. If you are replacing a cracked pane, swapping a damaged door for an identical one, or repainting in a similar colour, that is normally treated as maintenance and you can get on with it.
Planning permission is usually needed when the work materially alters the external appearance of the building. That includes changing the shopfront's overall design or proportions, switching materials (for example from timber to aluminium), altering the fascia height, moving the entrance, or installing external roller shutters where there were none before. Because a full shopfront replacement almost always changes the appearance in some way, most new shopfronts in Birmingham do go through a planning application.
Birmingham has over 30 conservation areas, including the Jewellery Quarter, Moseley, Bournville and parts of the city centre. If your premises is in one, the council applies stricter tests on design, materials and shutters. Externally mounted solid roller shutters are routinely refused in these areas; open lattice or brick bond shutters, or internal shutters behind the glass, stand a far better chance.
Listed buildings are a separate matter. Any alteration that affects the character of a listed building needs listed building consent as well as, or instead of, planning permission, and carrying out work without it is a criminal offence. If you are unsure of your building's status, check the council's online mapping or Historic England's list before ordering anything. A good shopfront installer will do this check with you at survey stage.
A common surprise is that the sign above your shop is dealt with under a different regime. Illuminated fascia signs, projecting signs and most signs above 4.6 metres need advertisement consent, which is a separate application from planning permission even if you submit both at once. Non-illuminated signs within certain size limits often benefit from deemed consent, but the rules tighten in conservation areas.
Roller shutters deserve their own thought too. An external shutter box and guides visibly change the front of the building, so they normally need planning permission. Birmingham, like many councils, prefers punched or perforated lath shutters over solid steel because they keep the street feeling active after hours. Planning this at the design stage is far cheaper than fitting a solid shutter and being asked to remove it.
A standard planning application for shopfront alterations is decided within eight weeks in most cases, and advertisement consent runs to a similar timetable. Application fees change periodically, but budget somewhere in the low hundreds of pounds per application, plus drawing costs if you need scaled elevations prepared, which most applications do. If your installer or a local architectural technician prepares the drawings, that typically adds a few hundred pounds more depending on complexity.
Planning permission is not the only approval to think about. Building regulations apply regardless of planning: new glazing in a shopfront must be safety glass to BS EN 12600 or BS 6206 in critical locations, entrance doors need to meet accessibility requirements under Part M, and structural alterations such as removing or replacing a lintel above the opening need sign off. A competent shopfront contractor will design to these standards as a matter of course, but it is worth confirming who is handling the building control application before work starts.
Internal shutters fitted behind the glazing usually avoid the need for planning permission because they do not change the outside of the building. External shutters with a visible box and guides normally need permission, and solid shutters are unlikely to be approved in Birmingham's conservation areas.
The council can serve an enforcement notice requiring you to undo the work or apply retrospectively, and unauthorised alterations to a listed building are a criminal offence. It is far cheaper to check first, as a retrospective application costs the same as applying properly but with the risk of refusal after the money is spent.
Allow roughly three to four months for a shopfront needing permission: a couple of weeks for survey and drawings, up to eight weeks for the planning decision, then fabrication and installation. Where no permission is needed, a straightforward aluminium shopfront can often be surveyed, made and fitted within four to six weeks.
