Body copy

Choosing the right signage is one of the most visible decisions a business makes. The wrong sign looks cheap, fades quickly, or fails to attract attention. The right one builds credibility and draws customers for years.

This guide explains every major signage type, what it costs, how long it lasts, and what it is best used for.

ACP (Aluminium Composite Panel)

ACP is the workhorse of shop signage. It is a flat panel made of two aluminium sheets bonded to a polyethylene core. It is lightweight, durable, weatherproof and relatively inexpensive.

Cost: KSh 3,000 – 8,000 per square metre Lifespan: 5–10 years outdoors Best for: Shop fronts, building signs, office branding, directional signs Pros: Cheap, durable, easy to install, wide colour range Cons: Flat only, can look basic, not illuminated

Acrylic signage

Acrylic signs are made from solid plastic (polymethyl methacrylate). They are more premium than ACP and are often used indoors for reception areas and office branding.

Cost: KSh 5,000 – 15,000 Lifespan: 10+ years indoors, 5+ years outdoors with UV protection Best for: Reception signs, office branding, indoor wayfinding, premium shop fronts Pros: Premium look, glossy finish, durable, can be illuminated Cons: More expensive than ACP, can yellow over time without UV protection

3D acrylic letters

3D acrylic letters are individual cut letters, often mounted on a wall or shop front. They add depth and dimension that flat signs cannot match.

Cost: KSh 800 – 2,500 per letter Lifespan: 10+ years Best for: Shop fronts, lobbies, reception areas, building identification Pros: Professional, dimensional, can be illuminated (halo-lit) Cons: More expensive than flat signs, installation is more complex

Channel letters

Channel letters are illuminated 3D letters, usually with LED modules inside. They are the premium outdoor option and are visible day and night.

Cost: KSh 1,500 – 4,000 per letter Lifespan: 10+ years (LEDs last 50,000+ hours) Best for: Professional shop fronts, corporate buildings, high-visibility locations Pros: 24-hour visibility, premium appearance, long-lasting Cons: Most expensive option, requires electrical installation

LED signs

LED signs are full digital displays that can show text, images and video. They are the most visible signage option and are suitable for high-traffic outdoor locations.

Cost: KSh 15,000 – 50,000+ Lifespan: 5–10 years depending on quality Best for: High-visibility outdoor locations, retail, entertainment venues Pros: Maximum visibility, can display dynamic content, attention-grabbing Cons: Expensive, requires power, can be distracting if overused

Neon signs

Neon signs use glass tubes filled with neon gas to create glowing text and shapes. They have a retro, decorative appeal and are popular for indoor use.

Cost: KSh 10,000 – 30,000 Lifespan: 5–10 years Best for: Indoor decorative signage, bars, restaurants, retail displays Pros: Unique aesthetic, eye-catching, customisable Cons: Fragile, limited to indoor use, higher maintenance

Lightbox signs

Lightbox signs are illuminated panels, typically used for 24-hour visibility. They consist of a printed graphic inside a lighted box.

Cost: KSh 8,000 – 25,000 Lifespan: 5–10 years Best for: 24-hour visibility, retail, restaurants, service stations Pros: Even illumination, good visibility, replaceable graphics Cons: Requires power, bulkier than flat signs

Pylon signs

Pylon signs are large, freestanding signs mounted on a tall pole. They are designed to be seen from a distance and are typically used for roadside businesses.

Cost: KSh 50,000 – 200,000+ Lifespan: 10–15 years Best for: Roadside businesses, petrol stations, shopping centres, estates Pros: Maximum visibility, can be seen from far, professional appearance Cons: Very expensive, requires permits, professional installation required

Monument signs

Monument signs are low, freestanding signs typically mounted on a brick or stone base. They are common for estates, campuses and corporate headquarters.

Cost: KSh 30,000 – 100,000+ Lifespan: 10–15 years Best for: Estates, campuses, corporate headquarters, churches, schools Pros: Professional, permanent, low maintenance Cons: Expensive, requires professional installation

How to choose the right signage

Consider your location. A sign visible from the road needs to be larger and more durable than one inside a building.

Consider your budget. ACP is the most affordable. Channel letters and LED signs are the most expensive. Choose the best option within your budget.

Consider visibility. If you need 24-hour visibility, choose an illuminated option (channel letters, lightbox or LED). If daytime visibility is sufficient, a flat sign may be enough.

Consider maintenance. All signage requires some maintenance. Illuminated signs require electrical maintenance. Choose a sign you can maintain.

Check permit requirements. Nairobi County requires signage permits. Check the requirements before ordering.
