Illuminated shop signs are one of the most powerful tools for attracting customers, especially in busy retail areas across the UK. But with our famously unpredictable weather, from constant rain and freezing winters to high winds and UV exposure, keeping illuminated signage performing at its best can be challenging. Without the correct maintenance, even the brightest sign can quickly lose impact.

At Hardy Signs, we’ve been manufacturing and installing illuminated signage since 1993. After more than 30 years in the UK signage industry, we understand exactly how the climate affects signage and the steps required to keep your investment shining brilliantly all year round.

Why the UK Climate Takes a Toll on Illuminated Signs

Our weather conditions can significantly impact the appearance, brightness and structural integrity of illuminated signage:

• Frequent rainfall can cause moisture ingress and corrosion.
• Strong winds may loosen fixings or damage external components.
• Temperature swings cause materials to expand and contract.
• Snow and ice add weight and strain to sign structures.
• UV rays fade surfaces and reduce lighting clarity over time.

Without regular maintenance, minor issues can turn into costly repairs.

Types of Illuminated Signs & Their Care Requirements

Every illuminated sign, from LED and neon to traditional fluorescent lighting, needs tailored care:

LED Signs

Energy-efficient and durable but still require regular lens cleaning and inspection of electrical connections.

Neon Signs

Bright and eye-catching, but the glass tubes need careful cleaning and protection from temperature fluctuations.

Traditional Lighting

Fluorescent and incandescent signs require bulb replacements and frequent wiring checks due to shorter lifespans.

Essential Maintenance Practices for Long-Lasting Illuminated Signs

Here’s how businesses can protect their investment:

1. Regular Cleaning

Pollution, dirt and rain residue can dim your signage and damage materials. Monthly cleaning keeps your branding sharp and visible.

2. Electrical System Checks

Wiring and connectors should be inspected regularly to prevent faults, especially after extreme weather.

3. Replacing Components

LED modules, drivers, transformers and bulbs all degrade over time. Replacing them proactively keeps your sign bright and reliable.

Seasonal Maintenance

Winter:

• Check for snow or ice build-up
• Seal electrical components
• Inspect for water ingress
• Test lighting systems before peak trading periods

Summer:

• Clean more frequently due to increased dust
• Inspect for UV fading
• Ensure ventilation around electrical components
• Tighten structural fixings after high winds

Seasonal adjustments are the key to all-year performance.

Why Professional Sign Maintenance Makes a Difference

Bringing in signage experts ensures:

• Faster diagnosis of issues
• UK‐compliant electrical safety checks
• Extended lifespan of your signage
• Stronger protection against weather-related damage
• Maximum brightness and visibility

A professional maintenance schedule is particularly valuable for illuminated fascia signs, shopfront signage, digital displays and large exterior signs exposed to the elements.
