What is Secured by Design? The Police Preferred Specification Explained

Secured by Design (SBD) is the official UK police flagship initiative for crime prevention. It is not a private commercial entity; it is owned by the UK Police Service. The core concept revolves around the “Police Preferred Specification,” a high-level security standard for physical products. By having Secured by Design explained as a procurement framework, trade professionals can focus on reducing crime through environmental design and robust hardware. The goal is simple: create safer communities by making it significantly harder for criminals to gain entry to residential properties.

The Origins and Purpose of the Initiative

The police established SBD in 1989 to combat rising burglary rates in housing estates. It operates through Designing Out Crime Officers (DOCOs) who work across the UK to influence the built environment. These officers provide technical advice to planners and developers to ensure security is integrated from the start. Data from the initiative shows that SBD developments see up to a 75% reduction in crime compared to those without the accreditation. This success stems from combining physical security with smart landscaping and lighting, creating a layered defence that deters opportunistic intruders.

Police Preferred Specification vs Standard Products

The difference between a standard product and one with Police Preferred status lies in third-party verification. A standard window might meet basic functional needs, but SBD-certified products undergo rigorous testing to resist forced entry. This involves physical attacks using tools commonly used by burglars. Products must meet specific standards, such as PAS 24:2022, to carry the SBD logo. For your clients, this distinction carries financial weight; many insurance companies recognise SBD accreditation as a primary factor in risk assessment and premium pricing. Choosing these uPVC and aluminium windows ensures your installations provide genuine, proven protection rather than just the appearance of security.

Understanding SBD Accreditation Levels: Gold, Silver, and Bronze

SBD isn’t just about a single lock or a specific pane of glass. It is a comprehensive framework. Having Secured by Design explained in the context of its three-tier system helps you choose the right specification for your project. These levels, Gold, Silver, and Bronze, apply to the development as a whole rather than just individual units. Glazing plays a pivotal role in every tier. In Kent, local planning requirements often dictate which level you must achieve, especially in high-density urban areas or large-scale new estates. Designing Out Crime Officers (DOCOs) will often specify a tier based on the local crime profile and project scope.

The Gold Standard: Comprehensive Security

Achieving Gold requires a holistic approach to site safety. This is the highest level of accreditation available. It covers the physical perimeter, the building shell, and internal security measures. Gold is often specified for high-risk areas or prestigious new build projects where security is a primary selling point. To reach this standard, every entry point must be reinforced. Specifying aluminium bi-folding doors with SBD-certified hardware ensures the building envelope remains secure without compromising on modern aesthetics. It also demands careful consideration of site layout, communal access control, and the creation of defensible space.

Silver and Bronze: Targeted Protection

Silver accreditation focuses primarily on the physical security of the building shell. It requires all doors and windows to meet the Police Preferred Specification. This is often the preferred choice for developers who want robust security without the administrative burden of full site-wide Gold certification. It ensures the most vulnerable parts of the property are defended against forced entry. It’s a pragmatic middle ground for many residential builds in Kent and Sussex where site-wide landscaping isn’t fully under the developer’s control.

Bronze, meanwhile, is typically reserved for renovation projects or social housing where meeting minimum requirements is the priority. While Silver mandates certified products throughout, Bronze may allow for targeted upgrades to existing structures. The practical installation difference often comes down to the hardware used and the glass specification. For new build contractors and developers, understanding these nuances ensures you don’t over-specify or miss critical compliance targets. Sourcing compliant units from a single specialist keeps your project on track and within budget. Selecting the right tier ensures you meet both planning conditions and homeowner expectations for safety.

SBD and Building Regulations: Compliance for Trade Projects

For trade professionals, meeting Building Regulations is a non-negotiable priority. Having Secured by Design explained in the context of legal requirements clarifies why SBD-certified products are effectively the “easy button” for satisfying building inspectors. While Approved Document Q sets the minimum legal standard for security in new dwellings, SBD often exceeds these requirements. Using SBD-compliant glazing ensures you aren’t just meeting the law; you’re future-proofing the installation against evolving standards. It provides a documented trail of evidence that simplifies the sign-off process for any residential development.

Approved Document Q Requirements

This regulation applies to all new dwellings and buildings undergoing a change of use into residential units. It mandates that “easily accessible” windows and doors must be robust enough to resist physical attack. This includes ground floor windows, basement entry points, and any glazing accessible from a flat roof or balcony. Specifying uPVC casement windows that carry SBD accreditation guarantees that these vulnerable points meet the necessary security thresholds. Failing to provide evidence of compliance can lead to building control refusing to sign off the project, causing significant delays and financial penalties for the contractor.

PAS 24: The Technical Benchmark

PAS 24:2022 is the current technical benchmark for enhanced security performance. It is the core testing standard cited within Part Q. For a product to be considered secure, it must pass a series of rigorous attack tests conducted by a UKAS-accredited body. These tests simulate real-world burglary attempts through several methods:

• Manual intervention: Attempting to force entry using common tools like screwdrivers, crowbars, and pliers.
• Mechanical loading: Applying high levels of pressure to the locking points, hinges, and frame to test structural integrity.
• Impact testing: Using a pendulum or heavy weight to simulate a physical strike against the glass or frame.

Specifying PAS 24 is essential for any professional trade supply. It provides the documented proof that your windows and doors can withstand a sustained attack. Installers who provide non-compliant products face the prospect of costly retrofits if an inspector identifies a failure post-installation. Sourcing SBD-certified units from the start removes this uncertainty, providing a streamlined route to compliance for every project in Kent and Sussex. It protects both the homeowner and your professional reputation, especially when coupled with the 24/7 monitoring and emergency response services provided by H&T Experts Ltd.

Specifying the right components is the difference between a high-security installation and a vulnerable one. Having Secured by Design explained at a hardware level ensures you select products that genuinely resist intrusion. SBD compliance isn’t just about the frame; it’s an assembly of certified glass, locks, and reinforcement. Every element must work in unison to meet the Police Preferred Specification. Without this integrated approach, a single weak point can compromise the entire building envelope.

Laminated glass is a core requirement for high-security glazing, specifically P1A or P2A ratings. Unlike standard toughened glass which shatters on impact, laminated glass remains held together by an interlayer. This prevents “smash and grab” entries even if the glass is cracked. The structural integrity of the entire unit is paramount, which is why sourcing high-quality sealed units is vital. These units must be combined with multi-point locking systems and reinforced frames to prevent the sashes from being crowbarred open by a determined intruder.

SBD Composite Doors: The First Line of Defence

For many developers, composite doors are the preferred choice for SBD specifications. They offer a dense, reinforced core that resists drilling and heavy impact. Key features include anti-snap cylinders, which prevent burglars from bypassing the lock by snapping the barrel. Secure hinges and multi-point hooks provide additional anchor points within the frame. Don’t believe the myth that high security requires an industrial look. Modern SBD doors are available in various colours and styles, maintaining kerb appeal whilst providing maximum protection for the homeowner.

Aluminium and uPVC Windows: Secure Specification

Specifying aluminium windows or uPVC alternatives requires attention to the beading. Internal beading is a standard SBD requirement; it ensures the glass cannot be removed from the outside by prying away the beads. Hardware considerations are equally critical. You should specify friction stays that resist being forced open and shoot bolts that lock the sash into the frame at multiple points. Having Secured by Design explained in terms of window hardware helps you justify the use of reinforced hinges and locking handles to your clients. Whether you’re installing in a coastal Kent town or a rural Sussex village, these technical details ensure the window remains a barrier, not an entry point.

Frequently Asked Questions

Is Secured by Design a legal requirement for all new builds?

No, SBD itself isn’t a statutory requirement, but Approved Document Q of the Building Regulations is mandatory for new dwellings. SBD is often described as a voluntary enhancement that simplifies the building control process. By choosing SBD-certified products, you ensure the installation exceeds the minimum security benchmarks set by the government. It is a strategic choice for developers in Kent and East Sussex wanting to avoid compliance delays.

Can I get SBD accreditation for a single replacement window?

Individual windows can be manufactured to the “Police Preferred Specification,” but full SBD accreditation usually applies to the entire building envelope or development. When you order from Trade Tech Windows & Doors, you can specify that your uPVC or aluminium units must meet these security standards. This ensures the hardware and glass components are fully compliant with the initiative’s rigorous testing requirements for individual residential properties.

What is the difference between PAS 24 and Secured by Design?

Having Secured by Design explained requires distinguishing between a technical test standard and a police initiative. PAS 24:2022 is the specific benchmark used to test a window or door’s resistance to physical attack. SBD is the police-led scheme that uses PAS 24 as a baseline requirement for its membership. Essentially, all SBD products must pass PAS 24, but not all PAS 24 products are necessarily members of the SBD scheme.

Does Secured by Design help with home insurance premiums?

Many UK insurance providers recognise that SBD-certified homes are significantly less likely to be targeted by opportunistic criminals. Because these properties feature enhanced physical security, some insurers offer reduced premiums as a result of the lowered risk profile. It’s always worth advising your clients in Kent to mention the presence of SBD-compliant glazing when they are negotiating their home insurance policies to secure potential professional discounts.

Are all composite doors automatically Secured by Design compliant?

Not every composite door on the market meets the initiative’s standards. Compliance depends on the specific combination of the door leaf, the frame, and the hardware used during the assembly. To be SBD-compliant, the entire door set must be tested and certified as a single unit. Trade Tech Windows & Doors supplies composite doors that are specifically engineered and tested to meet these rigorous police-preferred specifications for maximum site security.

How do I check if a trade supplier is providing genuine SBD products?

You can verify a supplier’s credentials by searching the official SBD member company directory. Genuine products will also be accompanied by technical data sheets confirming they have passed PAS 24:2022 testing. Trade Tech Windows & Doors provides full transparency regarding the security credentials of our uPVC and aluminium range. We ensure all contractors in Kent and East Sussex have the necessary certification to prove compliance to building inspectors.

Do Secured by Design windows look different from standard windows?

There is no visible difference between a standard window and one built to SBD standards. The enhancements are entirely structural and mechanical, such as reinforced profiles, internal beading, and upgraded locking points. This means you can achieve high levels of security without compromising the visual appeal of a property. Whether you are installing aluminium bi-folds or uPVC casements, the finished look remains clean and professional whilst providing superior protection.

Can aluminium bi-fold doors meet Secured by Design standards?

Yes, aluminium bi-folds can achieve SBD status provided they are fitted with the correct security hardware. This includes high-security cylinders, reinforced hinges, and multi-point locking systems that secure the sashes into the track. Laminated glass is also a critical requirement for these large glazed areas. When specified correctly, these doors provide an excellent balance of modern aesthetics and the robust physical security required for high-end residential projects in the South East.
