How to Brief a Signage Printing Company: Electrician's Guide

Getting your electrical signage right starts before the printer ever sees a design file. A clear, comprehensive brief that covers safety standards, electrical specifications, durability needs, and compliance requirements will save you time, money, and — most importantly — ensure your signs actually protect people and meet UK law. In my 18 years as a qualified electrician, I've seen far too many sites with inadequate warning labels, non-compliant consumer unit signage, and EV charger warnings that don't meet ISO 7010 or BS 5499-1 standards. This guide walks you through exactly what to communicate to your signage company.

Why Proper Briefing Matters for Electrical Signage

Electrical signage isn't decorative. It's a legal requirement and a safety control. Under the Health and Safety (Safety Signs and Signals) Regulations 1996, you must ensure warning signs are:

• Clear and visible to anyone who might encounter a hazard
• Compliant with recognised standards (BS 5499-1, ISO 7010)
• Durable enough to survive the environment they're installed in
• Properly maintained throughout their lifespan

A poorly briefed signage company might produce signs that look fine but don't meet these requirements. They might use the wrong colour, wrong symbol, wrong material, or wrong dimensions. When an accident happens and HSE investigators arrive, inadequate signage is often cited as a contributing factor. You'll want documentation showing you commissioned compliant signs from a competent supplier — and that starts with a proper written brief.

I've also found that good briefing prevents costly reprints. When you're clear about electrical safety standards upfront, the printer knows exactly what's required and can flag issues before production.

Understand Your Signage Needs First

Before you contact a printer, be specific about what you actually need.

Are you labelling:

• A consumer unit or distribution board?
• An EV charging installation?
• An electrical plant room or equipment enclosure?
• High-voltage cable runs or underground ducting?
• Temporary site electrical installations?
• PPE requirement signs for electrical work areas?
• Testing and tagging station notices?

Each has different requirements. A consumer unit warning sign looks and functions very differently from an EV charger warning, which differs again from a high-visibility "Electrical Installation Work Activities" notice on a construction site.

Write down:

• Exact location(s) where signs will be installed
• Indoor, outdoor, or mixed environment
• Exposure to moisture, UV, extreme temperatures, or chemicals
• Size constraints (wall space available, viewing distance)
• Who needs to understand the sign (operatives only, public, visitors, contractors)
• Regulatory or insurance requirements specific to your installation

This clarity helps the printer recommend appropriate materials and finishes — and gives you confidence they understand the job.

Key Information to Include in Your Brief

Your written brief should contain:

Site and installation details:

• Full address
• Type of electrical installation
• Number of signs required
• Installation surface (painted wall, metal enclosure, cable tray, etc.)

Hazard and message specifics:

• What hazard is the sign warning against?
• Any mandatory text or legal wording that must be included?
• Any colour-coded electrical labels required (e.g., circuit identification)?
• Is this for a fixed installation, temporary site, or maintenance area?

Regulatory references:

• State that signs must comply with BS 5499-1 and/or ISO 7010
• If applicable, note Health and Safety (Safety Signs and Signals) Regulations 1996 compliance
• Mention any industry-specific standards (DNO requirements for EV chargers, for example)

Environment details:

• Indoor or outdoor
• Temperature range
• Moisture exposure
• Chemical exposure or cleaning regime
• UV exposure duration

Approval and contact:

• Who will approve the proof?
• When do you need it?
• Contact details and preferred communication method

A well-structured brief is a one-page document. Don't overwhelm the printer with irrelevant information, but don't leave them guessing either.

Electrical Safety Standards and Compliance

This is non-negotiable. Your brief must state clearly which standards apply.

BS 5499-1 covers safety signs and labels in the workplace. It defines dimensions, colour, contrast, and symbol requirements. For example:

• Warning signs are yellow and black (triangular)
• Prohibition signs are red and white (circular with a slash)
• Mandatory instruction signs are blue and white (circular)

ISO 7010 provides standardised symbol designs. If you're using ISO 7010 symbols, specify this — it ensures global consistency and clarity.

For electrical installations specifically, you often need:

• High voltage warning signs (yellow and black triangles with the HV symbol)
• Electrical hazard labels on distribution boards and switchgear
• Maintenance and testing notices (date of last inspection, qualified person details)
• EV charger warning signage (increasingly prescribed by charging network operators and DNOs)

Mention these standards by name in your brief. A competent signage company will know what "BS 5499-1 compliant, yellow and black, ISO 7010 symbol" means. If they ask for clarification, they understand the brief is important. If they don't, they might not take compliance seriously.

Design Specifications You Must Provide

Be specific about what the sign should say and look like.

Text:

• Provide exact wording (or confirm the printer can supply standard electrical safety text)
• State minimum and maximum font sizes if the space is tight
• Specify if text must be in English only or multilingual

Symbols:

• Confirm which ISO 7010 symbol is appropriate (e.g., W001 for general warning, W008 for high voltage, W017 for moving parts)
• Provide a reference or image if you have one
• Ask the printer to confirm the symbol before production

Colour:

• State exact Pantone reference if you need a branded colour on the safe part of the sign (but not the hazard symbol itself — those must follow the standard)
• For electrical safety, typically yellow/black, red/white, or blue/white
• Confirm that any laminate or gloss finish won't reduce visibility or create glare

Dimensions:

• Provide measurements in millimetres
• State if the sign must fit a specific wall space, enclosure, or cable label template
• Remember: signs must be large enough to be seen and read from the expected distance. A 50mm square label on a low-voltage cabinet in a utility room is fine; a 50mm label on high-voltage outdoor equipment is not.

Substrate and backing:

• Do you want adhesive labels (pressure-sensitive vinyl), rigid labels (rigid PVC or polycarbonate), or fixed signs bolted to walls?
• Will it be applied to metal, plastic, or painted surfaces?

Material and Durability Requirements

Your brief must specify where and how long these signs need to last.

Outdoor electrical signage (EV chargers, external switchgear, pole-mounted warnings):

• Use UV-stable vinyl or polycarbonate
• Expect £8–25 per sign for decent outdoor-rated material (prices vary by size and supplier)
• Specify at least 5-year durability minimum; 10 years is more realistic for outdoor installations
• Laminated finishes offer better durability than unlaminated vinyl

Indoor electrical signage (consumer units, plant rooms, switchboards):

• Standard vinyl or laminated paper is acceptable
• Expect £3–12 per sign depending on size and complexity
• Confirm the site environment (is the electrical room damp? hot? subject to frequent cleaning?)

Colour-coded electrical labels (for circuits, conductors, or identification):

• Specify if you need adhesive labels or wraparound tags
• State if these need to withstand cable flexing, moisture, or chemical exposure
• Confirm compliance with colour codes relevant to your installation (e.g., BS 7671 conductor identification)

Temporary vs permanent:

• If signs are for a temporary site installation, specify the expected duration
• Temporary construction signage has lower durability requirements but still must meet safety standards

In your brief, write: "These signs will be installed in [location] and must withstand [temperature, moisture, UV, cleaning] exposure. We require materials rated for minimum [5/10] years' outdoor durability" or equivalent for indoor applications.

Questions to Ask Before Ordering

Before you commit, ask the signage company:

1. "Can you confirm these designs comply with BS 5499-1 and ISO 7010?" Don't accept vague answers. They should reference the standard in writing.

2. "What's your colour match tolerance?" Safety colours must be accurate. Ask if they use Pantone references or colour swatch samples.

3. "Will you provide a digital proof before production?" You need to review size, text, symbols, and colour on screen.

4. "What's the lifespan of your material in [your environment]?" They should be able to specify durability in outdoor UV, moisture, or temperature ranges.

5. "Can you supply a certificate of compliance with BS 5499-1?" Reputable suppliers will provide this. It's valuable for HSE documentation.

6. "What's your lead time and delivery cost?" Don't assume standard timescales. Complex signage or large orders may take 2–4 weeks.

7. "Do you have experience with electrical safety signage?" A competent printer will have examples and can discuss standards without prompting.

How to Review Proofs and Samples

When the printer sends a proof, check:

Visual accuracy:

• Does the symbol match ISO 7010 exactly? (Download the symbol from the ISO or a licensed library if you're unsure.)
• Are colours correct and high-contrast?
• Is text legible in the proof? Remember, printed material may look sharper or duller than on screen.

Compliance:

• Does the proof state "BS 5499-1 compliant" or similar?
• Are dimensions noted and correct?
• Is the hazard symbol the right size relative to text and background?

Practical fitness:

• If it's an adhesive label, is the adhesive type suitable for your surface?
• If it's rigid, are fixing points clearly marked?
• For colour-coded labels, do the colours match your electrical system (e.g., UK colour codes for circuit identification)?

Durability features:

• If outdoor, is the material UV-stable and laminated?
• For wet areas, is it waterproof?
• Are edges sealed (for adhesive labels) or protected (for rigid signs)?

Request a physical sample before full production if this is a large order or critical installation. Cost is usually £20–50 for a sample, well worth it for peace of mind.

Common Mistakes When Briefing Signage Companies

I see these repeatedly on sites:

1. Vague briefs. "We need a warning sign for the electrical cabinet." Gives the printer no detail. Specify size, location, exact hazard, regulatory standard, and environment.

2. Assuming they know electrical standards. Not all signage companies understand BS 5499-1 or ISO 7010. State it explicitly in writing.

3. Choosing the cheapest quote without checking compliance. A £2 sign that doesn't meet standards is worthless and legally risky. Expect to pay £5–20 per sign for genuinely compliant, durable electrical safety signage.

4. Forgetting to account for installation surface. A label suitable for smooth painted metal won't adhere well to rough blockwork or wet surfaces. Specify your surface in the brief.

5. Underestimating lead times. Order custom electrical signage at the last minute and you'll either miss deadlines or pay rush fees (often 25–50% premium).

6. Not getting compliance documentation. Always ask for a brief statement confirming BS 5499-1 compliance and material durability. It matters if HSE ever inspects.

7. Ignoring colour accuracy. Electrical safety colours (yellow, red, blue) must be recognisable at a glance. If your printer can't guarantee colour accuracy, they're not suitable for electrical safety work.

Timeline and Delivery Expectations

Realistic timescales:

• Standard electrical safety signage (off-the-shelf designs, small quantities): 5–10 working days. Cost: £5–15 per sign.
• Custom or complex signage (bespoke symbols, specific text, large sizes): 10–20 working days. Cost: £15–40 per sign.
• Bulk orders (100+ signs): 2–4 weeks, with volume discounts possible (10–25% reduction).
• Urgent/rush orders: possible within 2–5 days but expect a 25–50% premium.

Include in your brief: "We require delivery by [date]. Please confirm if this is achievable and state any rush fees."

Delivery typically costs £10–30 depending on location and weight. Small label orders might be sent Royal Mail; larger signage often requires courier.

FAQ

Q: Can I use a generic template electrical warning sign from a website instead of commissioning custom signage?

A: You can, if it's genuine BS 5499-1 compliant. But generic templates often don't account for your specific hazard, location, or regulatory requirement. For example, a generic "high voltage" sign is fine on a fixed distribution board but inadequate on an EV charger installation, where DNO and charging network operator requirements often mandate specific wording and symbols. I'd always recommend at least a brief call with the signage company to confirm your specific installation needs are met. It's not expensive and removes doubt.

Q: What's the difference between ISO 7010 and BS 5499-1? Do I need both?

A: BS 5499-1 is the UK standard that defines how safety signs should look — colours, dimensions, contrast, symbol placement. ISO 7010 specifies the actual symbols themselves. In practice, a compliant sign follows BS 5499-1 and uses ISO 7010 symbols. You don't "choose" between them; you need both. Tell your printer "BS 5499-1 compliant with ISO 7010 symbols" and you're covered.

Q: Can I use colour-coded electrical labels instead of full warning signs?

A: Not for safety hazard warnings. Colour-coded labels (e.g., BS 7671 circuit identification) serve a different purpose — they identify circuits or conductors. You need actual warning signs (yellow/black triangles, red/white prohibition signs, etc.) for hazards. Use both where relevant: colour-coded labels for identification, warning signs for hazards.

Q: Are laminated signs better than vinyl?

A: Depends on the environment. Laminated signs (vinyl with a protective laminate layer) offer better durability in wet, high-UV, or high-traffic areas — they resist fading, peeling, and damage. Standard vinyl is cheaper and fine for protected indoor locations. For outdoor electrical signage (EV chargers, external switchgear), I specify laminated material without hesitation. Cost difference is usually 20–30% but the extra lifespan justifies it.

Q: Do I need a separate brief for every signage company, or can I use the same one?

A: You can use the same core brief, but personalise it slightly for each supplier. For example, if one printer uses a specific material or process, mention that in your follow-up communication. The core brief — site details, standards, environment, durability — remains constant. A well-written brief can be reused across suppliers, which actually helps you compare quotes fairly.
