Quick Answer:
What You Need to Know Before Installing or Changing a Shopfront in London
Shopfront planning permission is required when you decide to change the design, structure, signage, or materials of your storefront. Local councils assess applications based on appearance, materials, and impact on the street scene. Most approvals take 8–12 weeks, depending on the borough and location.
In London, a shopfront is more than just an entrance; it’s a key part of the city’s architectural identity.
Local councils strictly regulate shopfront designs to ensure they respect the surrounding “street scene” and maintain the character of each area.
At Redwood Shopfront, we’ve spent years working across London’s 32 boroughs (including the City of London), helping businesses navigate planning rules and get approvals faster.
This guide breaks down the process, key design principles, and how to avoid common mistakes.
Why London Councils Care About Your Shopfront
London’s high streets are a mix of historic and modern architecture. Councils treat shopfronts as a critical part of the streetscape and aim to balance:
- Commercial visibility
Architectural consistency
Heritage protection
Public safety and accessibility
In recent years, many boroughs have tightened their requirements—especially around accessibility, signage, and maintaining “active frontages.”
Do You Always Need Planning Permission?
The short answer is: Usually, yes.
If you are making a “material change” to the appearance of your building, you need planning permission. Includes:
| Task | Permission Required? | Note |
|---|---|---|
Like-for-Like Repairs |
Usually No |
Using identical materials and colors. |
New Signage/Fascias |
Yes |
Requires “Advertisement Consent.” |
Structural Changes |
Yes |
Changing doors, windows, or stallrisers. |
Illuminated Signs |
Yes |
Strict rules in Conservation Areas. |
Internal Refurbishment |
No |
Unless it involves a “Change of Use” (e.g., Cafe to Bar). |
Expert Tip
If your property is listed or located in a conservation area, permitted development rights are often removed. Even minor changes may require Listed Building Consent.
Core Design Principles for London Shopfronts
Most councils follow Supplementary Planning Documents (SPDs). To pass, your design should focus on:
1. Respecting Proportions
A new shopfront should never be designed in isolation. It must relate to the upper floors of the building.
- Vertical Alignment: Mullions and pilasters should align with the windows above.
- The 1/5th Rule: The combined height of the fascia and cornice should generally not exceed 20% of the total shopfront height.
2. Materials and Colors
Councils prioritize durability and visual consistency.
Preferred materials:
- Timber (especially in conservation areas)
- Stone and metal
- Powder-coated aluminium
Avoid:
- uPVC
- Reflective plastics
- Cheap or overly modern finishes
Colors:
- Subtle, heritage tones are preferred
- Bright or neon colors may be rejected
3. The “Active Frontage” Requirement
London planning policy encourages vibrant streets.
- Windows should remain transparent
- Avoid blackout vinyls or heavy tinting
- 70–75% of glazing should allow visibility inside
4. Security Features (Shutters & Grilles)
Security is important, but design matters.
Councils typically prefer:
- Internal grilles instead of external shutters
- Perforated or see-through designs
- Powder-coated finishes

Special Rules for Conservation Areas
If your shop is in a conservation area, expect stricter rules:
- Timber shopfronts are often required
- Modern designs may be rejected
- Bright signage is restricted
- Historic features must be preserved
These areas are heavily protected, so planning approval becomes more detailed and selective.
The Application Process: Step-by-Step
Getting the green light isn’t magic, it’s just a process.
- Get Pre-Application Advice: Most councils let you run your ideas past a planner for around £50 to £150 before you officially apply. Do this. It flags major problems before you drop serious cash on an architect.
- Get Proper Drawings: A back-of-a-napkin sketch won’t cut it. You need proper, scaled architectural drawings. Usually, this means 1:50 for the overall look and 1:20 for the nitty-gritty details, like the cornice shape.
- The Planning Portal: Submit your forms, site map, and fees (typically £250–£300) via the UK Planning Portal.
- The Wait: Most shopfront planning applications in London are decided within 8 weeks, but in practice, timelines often extend to 10–12 weeks. Applications in conservation areas can take longer due to stricter design reviews and additional approval layers.
Common Mistakes to Avoid
- Installing a shopfront without permission
- Using non-compliant materials
- Adding oversized signage
- Ignoring conservation area restrictions
- Choosing external shutters without approval
These mistakes can delay your project or lead to legal issues.

FAQs: London Council Planning for Shopfronts
Can I change my shopfront color without permission?
If it is a standard maintenance repaint using the same or a very similar color, permission is usually not required. However, if the color change is significant, or if the building is Listed or in a Conservation Area, you will likely need Planning Permission or Listed Building Consent. Councils can intervene if a color is deemed “detrimental to the character of the area.
How much does a planning application cost?
Planning application fees for shopfront changes in London typically start at £309, plus a Planning Portal service charge £75 + VAT).
If signage requires Advertisement Consent, an additional £165 applies. In total, most applications cost between £385 and £550, depending on the scope.
What happens if I build without permission?
Building a shopfront without planning permission can lead to an Enforcement Notice, requiring you to remove or alter the work at your own expense. Councils may also issue fines or take legal action, especially in conservation areas or for repeated violations.
How long does planning permission take in London?
Once your application is “validated” by the council, the statutory period for a decision is 8 weeks. However, in busy boroughs like Camden or Westminster, it is wise to allow 10–12 weeks to account for the initial validation period and potential backlogs.
