Shop front alterations: do I need planning permission?

Shop front alterations can require planning permission where the works materially affect the external appearance of the building and no permitted development right applies. A genuine like-for-like repair may fall outside the definition of development, while a redesigned frontage, new opening, shutter, cladding or other visible change needs a closer planning check.

Signs are controlled separately under the advertisement regime, and listed building consent can apply independently of planning permission. The exact package of works therefore matters more than simply calling the project a ‘shop-front replacement’.

When are shop front alterations development?

 

The first question is whether the work amounts to development at all. Section 55 of the Town and Country Planning Act 1990 excludes building operations which affect only the interior or do not materially affect the external appearance of the building.

A genuinely like-for-like repair or replacement can therefore fall outside planning control. A redesigned shop front, a new entrance, a materially different window arrangement, new cladding, projecting features or other visible alterations are much more likely to amount to development. The description on an invoice is not decisive: the council will look at what physically changes on the building.

 

Do shops have permitted development rights for alterations?

 

Some non-domestic buildings can use permitted development rights under Part 7 of the GPDO. In particular, Class A can permit qualifying extensions or alterations to certain commercial premises, subject to its detailed limitations and conditions.

Do not assume that every shop-front alteration falls within Class A simply because the premises are in Use Class E. Check the building, the existing lawful use, the nature of the works and the actual wording of the permitted development right. An Article 4 direction or a condition on an earlier planning permission can also remove a right which would otherwise exist.

 

Roller shutters and security shutters

 

External roller shutters can have a much greater visual effect than their practical purpose suggests. Solid shutters, shutter boxes and guides can materially alter a shop front and will commonly need planning permission where no permitted development right applies.

Authorities often prefer open-grille or internally mounted security solutions because they retain activity and natural surveillance in the street when the premises are closed. Local design policies and conservation-area guidance can be important, particularly on traditional shopping streets.

 

Signs and advertisement consent are separate

 

Changing the fascia, projecting sign, lettering or illuminated advertisement can engage the separate advertisement-control regime. Some advertisements benefit from deemed consent if all the relevant conditions are met; others require an application for express advertisement consent.

The rules are in the Town and Country Planning (Control of Advertisements) (England) Regulations 2007, as amended. See our guide to advertisement consent for the practical routes.

Displaying an advertisement without the consent required by the Regulations can be a criminal offence. Do not treat advertisement consent as something which can always be sorted out later simply because the underlying shop front has planning permission.

 

Listed buildings and conservation areas

 

If the shop is a listed building, listed building consent is required for works which would affect its character as a building of special architectural or historic interest. That can include internal as well as external work, historic joinery, stallrisers, pilasters, cornices, doors and glazing.

A conservation-area designation does not automatically mean every shop-front alteration needs planning permission, but the character and appearance of the area will be a material consideration where an application is required. An Article 4 direction can also remove permitted development rights locally.

 

New doors, access ramps and accessibility

 

Widening or relocating an entrance can be development where it materially alters the exterior. A new ramp, platform, handrail or level change may also need its own planning assessment, particularly where it projects onto or close to highway land.

Accessibility duties and planning control are separate regimes. The fact that works are intended to improve access does not automatically grant planning permission, although the need for inclusive access can be an important part of the design and planning case.

 

Extraction, air conditioning and plant

 

A shop-front project sometimes comes with other external equipment such as an extraction flue, condenser, ventilation grille or plant enclosure. Those items should not be assumed to form part of the shop-front permission or permitted development right. Noise, odour and visual impact can make them significant planning issues in their own right.

 

Building Regulations and the lease

 

Building Regulations may apply to structural changes, glazing, thermal performance, accessibility and other elements of a new shop front. Building Control approval does not replace planning permission or listed building consent.

If you are a tenant, also check the lease and obtain any landlord or freeholder approval required before starting work. Private consent does not replace planning consent, and planning consent does not override the lease.

 

What to check before changing a shop front

 

• whether the works materially affect the external appearance
• whether a Part 7 permitted development right applies
• whether an Article 4 direction or planning condition removes that right
• whether the building is listed or within a conservation area
• whether signs need advertisement consent
• whether shutters, extraction equipment or plant need separate permission
• whether the works affect highway land or the public footway
• whether Building Regulations and landlord approval are also required
