Why Choose Union Security?

Union's standing as a premium British security brand is built on decades of continuous improvement and responding to evolving security threats.

The brand's reputation among professional locksmiths is particularly strong, with many regarding Union as their first choice for quality and reliability. This professional endorsement stems from Union's attention to manufacturing precision, consistent quality control, and the longevity of their products even under heavy use.

The availability of spare parts and extensive product ranges means locksmiths can standardise on Union products across multiple job types, simplifying van stock management and reducing call-backs.

Union also demonstrates exceptional understanding of the UK market, designing products specifically for British door construction, climate conditions, and security requirements rather than adapting continental designs.

Key Features of Union Security

Union Security products incorporate numerous advanced features that distinguish them from generic security hardware. Their cylinder locks feature anti-snap technology with sacrificial break points, anti-drill hardened pins, and anti-pick pin configurations that resist manipulation attempts. Many Union cylinders offer three-star Kitemark certification—the highest security rating available—providing genuine protection against the lock-snapping epidemic that affects cylinder locks.

Union mortice locks benefit from precision-engineered lever mechanisms with up to 2,000 key differs, substantial bolt throws (typically 20mm or more), and case-hardened steel components that resist drilling and sawing attacks. Their deadlocks and sashlocks are manufactured to tight tolerances, ensuring smooth operation over many years whilst maintaining security integrity. Reversible mechanisms and handed options provide installation flexibility, whilst satin chrome, polished brass, and satin brass finishes complement various architectural styles.

The brand's padlock range showcases hardened steel shackles, laminated steel bodies, and cylinder mechanisms resistant to picking and impressioning. Weather-resistant designs with protective covers suit external applications, whilst long-shackle and specialist variants address specific security scenarios from van locks to gate security.

Popular Union Security

The Union Security range encompasses several product categories, each addressing specific security requirements. Their cylinder locks include euro profile cylinders in various sizes, oval cylinders for traditional rim locks, and specialist cylinders for UPVC doors and timber applications. Union's three-star cylinders represent the pinnacle of cylinder security, incorporating multiple attack-resistant features in insurance-approved packages suitable for both domestic and commercial premises.

Union mortice locks span British Standard 5-lever deadlocks for ultimate insurance-approved security, sashlocks combining latch and deadbolt functions for everyday use, and bathroom locks for privacy applications. Their StrongBOLT range offers enhanced security features at competitive price points, whilst traditional 3G series locks provide time-tested reliability for standard residential installations.

The padlock selection includes solid brass padlocks for internal use, laminated steel models for external applications, and heavy-duty close-shackle designs for high-security requirements. Keyed-alike and master-keyed options simplify key management for contractors and facilities managers managing multiple padlocked locations.

Safety and Compliance

Union Security products are designed and manufactured to meet stringent UK and European safety standards. Many Union locks carry BS 3621 approval—the British Standard for thief-resistant locks—which is typically required by insurance companies for residential properties. This certification ensures locks resist specific attack methods including drilling, picking, and physical force for designated time periods under test conditions.

Kitemark certification on Union cylinders and locks provides additional assurance, indicating products have passed independent testing by BSI and are subject to ongoing quality surveillance. Union's three-star cylinders meet TS007 standard requirements, offering the highest level of cylinder security currently available and satisfying Secured by Design specifications for police-approved developments.

When installing Union Security products, tradespeople should follow manufacturer instructions carefully, ensuring correct door preparation, accurate alignment, and appropriate fixing methods. Fire door applications require particular attention, with locks and latches specified to maintain fire ratings and comply with Building Regulations Part B. Union provides comprehensive technical documentation supporting compliant installations across residential, commercial, and public building applications.

Frequently Asked Questions

Are Union locks insurance-approved?

Many Union locks carry BS 3621 certification, which is the British Standard typically required by insurance companies for residential properties. Union's 5-lever mortice deadlocks and three-star cylinders meet or exceed insurance requirements, but you should always verify specific requirements with your insurance provider as policies vary.

What does three-star rating mean on Union cylinders?

Three-star rating indicates the highest level of cylinder security under the TS007 standard, demonstrating resistance to multiple attack methods including picking, drilling, and snapping. Union three-star cylinders incorporate sacrificial break points, anti-drill pins, and anti-pick mechanisms, providing genuine protection against modern burglary techniques favoured by opportunist criminals.

Can Union locks be master-keyed?

Yes, many Union mortice locks and cylinders can be incorporated into master key systems, allowing facilities managers and property owners to operate multiple locks with one master key whilst providing individual keys to occupants or tenants. This requires professional locksmith services to specify, order, and install appropriate keyed configurations during initial installation.

How do I identify which Union lock I need to replace?

Union locks typically feature identification markings on the faceplate or body. Key measurements include case depth, backset (distance from door edge to keyhole), and overall case size. Taking photographs of existing locks and measuring these dimensions helps ensure accurate replacements. Professional locksmiths can identify Union models and specify exact replacements or suitable upgrades maintaining existing door preparations.

Are Union Security products suitable for coastal environments?

Union manufactures specific products for external and harsh environment applications, with corrosion-resistant finishes and weather-protected mechanisms. Their marine-grade padlocks and external-rated cylinders feature protective covers and corrosion-resistant materials suitable for coastal properties. However, regular maintenance with appropriate lubricants extends product life in challenging environments where salt air accelerates corrosion.
