BSI Kitemarked to BS EN 13422 under licence KM649097 and supplied with a pocketed prismatic D2 reflective sleeve as standard. The UV-stabilised virgin HDPE top maintains consistent blue colour across a full fleet deployment, ensuring the colour-coding system remains legible on site throughout a project. Available individually and in bulk packs of 100 and 200 for fleet procurement and utility operations running large cone inventories across multiple sites.
On a site where gas, water, electricity, and telecoms excavations are all open at the same time, the ability to identify which service type each excavation relates to without stopping to read a sign or ask a supervisor is a practical safety control. Blue is the recognised convention for water mains and potable water services in the UK, consistent with the colour coding used on utility maps, pipe sleeves, and service markers across the water industry. Deploying blue cones in a water main excavation corridor tells every operative on site exactly which service they are working near, reducing confusion between service types and the risk of accidental damage to the wrong utility. On multi-utility street works where orange cones manage traffic and blue cones identify the water service corridor, the colour distinction does the communication work without additional signage or barriers.
UV-stabilised virgin HDPE top: Colour uniformity across a full fleet deployment matters when the cone colour is part of the site safety system. UV stabilisation maintains consistent blue pigment over extended outdoor use, ensuring the cone reads as blue rather than a faded or inconsistent shade that could be confused with another colour in the fleet.
BSI Kitemarked to BS EN 13422: Independently assessed and certified by BSI under licence KM649097. Meets procurement requirements on local authority and Highways England frameworks where self-declared BS EN 13422 conformance is not accepted. The same Kitemark certification that covers the orange variant applies to the blue cone.
Pocketed prismatic D2 reflective sleeve fitted as standard: Utility works frequently run overnight and in all weather conditions. The prismatic pocketing delivers greater retroreflectivity than a standard flat reflective sleeve, maintaining visibility at approach speed in wet conditions and after dark without a separate beacon.
Two-piece construction for component replacement: Top and base replace independently. On water industry and utility operations running large cone inventories across multiple sites, replacing only the damaged component significantly reduces per-unit replacement cost over the operational life of the fleet.
100% recycled PVC anti-slip base: Provides a stable deployment footprint on excavated, disturbed, and uneven ground surfaces typical of utility street works and civil engineering sites. Consistent with ISO 14001 sustainability procurement requirements.
Blue for water and utility service identification: Blue is the established UK site convention for water mains, potable water services, and subterranean utility works. Colour conventions are industry practice rather than statutory requirements under Chapter 8, but they are widely recognised across the water industry, civil engineering, and utility sectors.
Embossing and custom sleeve printing available: Top and base can be embossed with text or a logo. Custom sleeve printing is available for utility contractors who need project or service type identification on the cone body. Both are subject to minimum order quantities.

This blue road traffic cone is used by water industry operatives, utility street works contractors, and civil engineers deploying on UK construction and street works sites where water main excavations, potable water service corridors, or subterranean utility works require colour-coded identification. It suits procurement teams in the water industry and multi-utility contracting who need a certified cone that communicates service type visually across a site without additional signage. It is equally suited to principal contractors coordinating multi-utility excavations where orange, blue, yellow, and other colour-coded cones identify different service types simultaneously across a shared site layout.
Demarcating water main excavation corridors on street works and highway maintenance sites where potable water services are exposed or being worked on.
Identifying potable water service routes on civil engineering and infrastructure sites where multiple utility types are being installed or diverted simultaneously.
Marking the boundary of a water main reinstatement zone during road or footway reinstatement following a utility excavation.
Overnight utility street works where water main excavations require retroreflective cone visibility at approach speed in all weather conditions.
Multi-utility site layouts where blue cones identify water service zones alongside orange traffic management cones, yellow electrical hazard cones, and green ecological boundary cones.
Water industry depot and operational yard layouts where blue cones identify water service equipment storage and operational zones within a larger facility.
Civil engineering projects involving potable water infrastructure where colour-coded zoning is part of the site safety and environmental management plan.
Step 1: Confirm the blue cone colour convention is communicated to all site operatives before deployment. On multi-utility sites, ensure the full colour-coding system is included in site inductions and toolbox talks so every operative understands what each cone colour signals.
Step 2: Check the reflective sleeve is correctly seated on the cone body and the top is fully engaged with the base before deployment.
Step 3: Place cones consistently along the water service corridor or excavation perimeter. On utility street works, place at spacings consistent with your traffic management plan and the relevant street works code of practice.
Step 4: Before overnight or low-visibility deployment, confirm the prismatic sleeve is clean. Utility street works frequently involve mud, water, and disturbed ground surfaces that contaminate the sleeve surface and reduce retroreflective performance.
Step 5: Where a flashing beacon is required for overnight or high-risk deployments, fit the appropriate bracket before attaching the beacon to the cone apex.
Step 6: Stack cones for transport with tops nested and sleeves protected. Store away from prolonged direct UV exposure when not in active use.
Step 7: Before redeployment, inspect each cone. Replace cracked tops and split bases individually — only the damaged component needs replacing.
Not briefing operatives on the colour convention: Blue cones communicate service type only when every operative on site understands the convention. On a multi-utility site where operatives from different contractors are working simultaneously, the colour-coding briefing must be part of the principal contractor's site induction for every person on site.
Using blue cones for highway traffic management: Blue is not an approved colour for Chapter 8 highway traffic management. Orange cones are required on public carriageways. Using blue cones in a highway traffic management layout creates a compliance risk and may not be recognised by road users as a traffic management device.
Deploying with a fouled sleeve on overnight works: Utility street works generate significant mud and water contamination. A sleeve fouled with excavation spoil can lose retroreflective performance entirely. Clean sleeves before any overnight or low-visibility deployment.
Mixing blue cones into non-water service zones on a colour-coded site: On a site running a multi-colour system, a blue cone outside the water service zone creates confusion and undermines the entire colour-coding system. Blue cones must only appear at water service boundaries and corridors.
Replacing the entire cone when only one component is damaged: The two-piece construction exists to avoid this. A cracked top replaces independently of the base. Discarding both components when one is damaged increases replacement cost unnecessarily on high-turnover utility operations.
Colour conventions for utility and construction site cone use are established industry practice, they are not statutory requirements under Chapter 8 of the Traffic Signs Manual. Blue cones must not be used on public highways in place of orange Chapter 8 cones. On utility street works, deploy in accordance with the Safety at Street Works and Road Works: A Code of Practice and the relevant traffic management plan. Operatives placing or recovering cones in areas with plant or vehicle movements must wear EN ISO 20471 high-visibility clothing appropriate to the risk level of the work zone. Do not use road traffic cones as a substitute for certificated barriers, shoring, or protective systems where those are required by the excavation risk assessment under the Construction (Design and Management) Regulations 2015.
Wipe the reflective sleeve with a damp cloth after deployment in muddy or wet conditions, utility street works are among the most contaminating environments for sleeve performance. Do not use abrasive cleaners or solvents on the sleeve surface. Replace cone tops that are cracked, deformed, or no longer seat correctly on the base. Replace bases that have lost structural integrity or anti-slip profile. Both components are 100% recyclable at end of service life. The UV-stabilised HDPE top maintains consistent blue colour over extended outdoor use, but inspect periodically for significant colour fade or inconsistency across a fleet, which can compromise the visual clarity of the colour-coding system.
Q: Why would a utility contractor use blue cones specifically rather than orange ones?
A: On a multi-utility street works site where gas, water, electricity, and telecoms excavations are all open simultaneously, orange cones manage traffic but provide no information about which service type each excavation relates to. Blue is the recognised UK convention for water mains and potable water services, consistent with the colour coding used on utility mapping, pipe sleeves, and service markers across the water industry. Deploying blue cones in the water main corridor tells every operative on site exactly which service they are near without a sign or a briefing, reducing confusion and the risk of accidental damage to the wrong service.
Q: Is the blue cone Chapter 8 compliant for use on public highways?
A: This cone is BSI Kitemarked to BS EN 13422 and meets the structural and retroreflective requirements of the standard. However, Chapter 8 of the Traffic Signs Manual specifies orange as the required colour for highway traffic management cones on public roads. Blue cones must not be used in place of orange cones for highway traffic management. This cone is intended for use on construction sites, utility works sites, and civil engineering projects where colour-coded service identification is applied as part of a site safety system.
Q: What is the UK site colour convention for blue cones?
A: Blue is the established convention for water mains, potable water services, and subterranean water industry operations on UK construction and utility sites. It is consistent with the colour coding used on utility service maps, pipe sleeves, and marker posts across the water industry. On a site running a full colour-coded system, orange handles traffic management, blue identifies water services, yellow signals electrical hazard zones, and green marks ecological or welfare boundaries. Colour conventions are industry practice rather than statutory requirements, but they are widely recognised across utility contracting, civil engineering, and water industry operations.
Q: What is this cone NOT suitable for?
A: This cone must not be used on public highways in place of orange Chapter 8 traffic cones. It is not suitable as a substitute for certificated excavation barriers, shoring, or protective systems where those are required by a risk assessment under CDM 2015. It is a temporary colour-coded demarcation device for site use — it communicates zone type visually but does not physically prevent access by plant, machinery, or vehicles.
Q: Why does colour uniformity matter on a blue cone fleet?
A: On a site where cone colour is part of the safety system, an inconsistent shade that could be mistaken for another colour undermines the system. The UV-stabilised virgin HDPE top maintains consistent blue pigment across a full fleet deployment and over extended outdoor use. Faded or inconsistent blue that could be confused with green or grey at a distance reduces the reliability of the colour-coding system, particularly on large sites where cones may be viewed from a distance or in low light.
Q: Can I use blue cones alongside orange cones on the same site?
A: Yes. The blue and orange variants share the same two-piece construction, base system, and sleeve specification, so they stack and store together without compatibility issues. On a multi-utility street works or civil engineering site, running blue cones for water service identification alongside orange cones for traffic management is standard practice. The two colours operate in different parts of the site safety system and do not conflict.
Q: Can I get these cones embossed or printed with a service type or company identifier?
A: Yes. The top and base can both be embossed with text or a logo, and custom sleeve printing is available for service type identification or project marking. On water industry and utility operations where large cone fleets are deployed across multiple sites, embossing with a company or project identifier reduces loss and misuse of stock. All are subject to minimum order quantities. Contact the CMT sales team on 020 8311 1144 or at sales@cmt.co.uk to discuss options and lead times.
