When choosing new windows and doors, aesthetics, thermal efficiency, and cost are often top of mind. However, the most critical feature—security—can sometimes be overlooked or misunderstood. A standard lock and sturdy frame might seem sufficient, but in reality, they may not stand up to a determined intruder.
True home security isn’t just a component; it’s a complete, tested system designed to protect your home and loved ones. Understanding the standards that define this level of protection is the first step toward genuine peace of mind.
The Growing Need for Enhanced Security in Our Homes
In an ever-changing world, the importance of robust home security cannot be overstated. While statistics show a general downward trend in burglaries over the long term, a significant number of offences still occur annually. For instance, in 2024, approximately 422,000 domestic burglary offences occurred in England and Wales, highlighting the persistent threat.
Homes without adequate security measures are fundamentally more vulnerable; some reports indicate that properties lacking a security system are 300% more likely to be burglarised. This underscores the necessity for proactive security measures that go beyond basic locks.
This is where PAS 24 comes in. It is not just another piece of industry jargon; it is a critical benchmark for the security performance of windows and doors in the UK. PAS 24 certification provides a clear, verifiable assurance that a product has been independently and rigorously tested to withstand common methods of forced entry.
It offers a tangible measure of a product’s ability to provide an enhanced level of security, moving it from a simple building component to a crucial part of your home’s defence system.
Why “Beyond the Basics” Matters for Your Peace of Mind
Choosing a PAS 24 certified product means investing in a system proven to resist attack. It’s the difference between a door that simply closes and one that actively protects. This standard ensures that the entire doorset or window—including the frame, glass, hardware, and locking mechanisms—works together as a cohesive unit to deter intruders.
For homeowners, this translates directly into greater peace of mind, knowing their property’s most vulnerable points are fortified to a recognised British standard.
Understanding PAS24: The Foundation of Enhanced Security
To appreciate its value, it’s essential to understand what PAS 24 is and the purpose it serves. It forms the bedrock of modern fenestration security in the UK, providing a clear and reliable standard for manufacturers, builders, and homeowners alike.
What is PAS24? Decoding the Product Assessment Specification
PAS stands for Product Assessment Specification. Therefore, PAS 24 is a set of test methods and performance criteria that windows and doors must meet to prove they offer an enhanced level of security.
It is not a law in itself but a detailed specification that outlines how products should be tested to ensure they are robust enough to resist physical attacks. The standard is specifically designed to assess the performance of windows and doorsets intended for dwellings.
Why PAS24 Was Developed: Countering the Opportunistic Burglar
PAS 24 was developed to address a specific threat: the opportunistic burglar. Most burglaries are not elaborate, pre-planned heists. They are crimes of opportunity, carried out by intruders using basic tools like screwdrivers, crowbars, or simply brute force.
The standard was created to reduce this crime opportunity by setting a minimum standard of resistance against these common attack methods, ensuring that casual attempts at forced entry are far more likely to fail.
The Role of the British Standards Institute in Setting Security Standards
The British Standards Institute (BSI) is the UK’s national standards body, responsible for developing and maintaining thousands of standards that help make products and services safer, more efficient, and more reliable.
BSI developed and publishes the PAS 24 standard, regularly updating it to reflect new criminal techniques and advancements in security technology. This ensures the specification remains relevant and effective in providing a high level of security.
PAS24 as a Minimum Standard for Security Performance
It is crucial to understand that PAS 24 is a minimum standard for enhanced security. A product that achieves PAS 24 certification has passed a series of demanding performance tests, confirming it meets a baseline of resilience.
While higher security standards exist for more high-risk applications, PAS 24 provides the essential level of security suitable for the vast majority of UK homes, ensuring a significant upgrade over non-tested products.
PAS24 and Building Regulations: Meeting Legal Requirements with Confidence
While PAS 24 is a specification, its importance is amplified by its integration into UK building regulations. For certain projects, meeting this standard is not just recommended—it’s a legal requirement.
Approved Document Q (Part Q) Explained: Security for New Dwellings
In England, Approved Document Q (often referred to as Part Q) is a building regulation that sets out security requirements for new dwellings. Its primary mandate is that “reasonable provision must be made to resist unauthorised access” to any new home, or any existing building that is being converted into a new home. This regulation applies to all easily accessible windows and doors, such as those on the ground floor or other accessible locations.
How PAS24 Provides a Route to Approved Document Q Compliance
Approved Document Q does not mandate specific products but instead specifies performance levels. It explicitly states that one way to meet its requirements is by installing windows and doors that are shown to have been manufactured to a design that has been tested to the British Standard PAS 24. This makes PAS 24 certification the most direct and widely recognised method for demonstrating compliance, providing a clear path for builders and developers.
Implications for Private Builders and Home Renovators: When is PAS24 a Requirement?
For private builders constructing new homes, compliance with Part Q is mandatory, making PAS 24 certified products a near-necessity. However, for home renovators, the rules can differ. Part Q does not typically apply to replacement windows or doors in an existing home. Despite this, many homeowners voluntarily choose PAS 24 products during renovations to significantly upgrade their home’s security, recognising the standard as a best-practice benchmark regardless of legal obligation.
The Rigorous Journey to PAS24 Certification: What “Enhanced Security” Truly Means
The term “enhanced security” is not just a marketing slogan; it represents a product’s proven ability to withstand simulated, real-world attacks. This proof comes from a series of rigorous, independent tests.
An Overview of PAS24 Test Methods: Independent Verification for True Protection
To achieve certification, a window or doorset must be submitted to a series of performance tests defined within the PAS 24 specification. These test methods are designed to replicate the forces and techniques an opportunistic burglar might use. The product is subjected to a variety of mechanical and manual attacks to assess its overall resilience and the strength characteristics of its components.
The Role of Test Houses and Test Laboratories in the Certification Process
These critical tests are not performed by the manufacturers themselves. They are conducted by independent, UKAS-accredited test houses or test laboratories. This third-party verification is crucial as it ensures impartiality and maintains the integrity of the certification process. These facilities have the specialised equipment and expertise to carry out the tests exactly as prescribed by the PAS 24 standard.
Key Security Performance Tests: Simulating Real-World Attacks
The performance tests are comprehensive and target potential weak points. They typically include:
- Manual Attack Testing: A technician attempts to defeat the locking hardware and create an opening using a defined set of tools (like screwdrivers and craft knives) within a specific time limit.
- Mechanical Loading Tests: The window or door frame is subjected to high-pressure loads in different directions to test its structural integrity and ensure it doesn’t flex enough to be compromised.
- Impact Testing: A heavy, soft impactor is used to strike the door panel or window infill, simulating a physical attack like a shoulder barge or kick.
- Glazing Security: The tests ensure that the glass cannot be easily removed from the frame, even if it is broken.
Beyond Just Security: Additional Performance Characteristics
While the primary focus is on resisting forced entry, PAS 24 also includes assessments of additional performance characteristics. This can involve testing the durability and functionality of the hardware over thousands of cycles, ensuring the product is not only secure on day one but remains so throughout its service life.
“Tested To” vs. “Certified To”: A Critical Distinction for Consumers
This is a vital point for consumers. A manufacturer might claim their product is “tested to PAS 24,” which could mean a single prototype passed a test once. “Certified to PAS 24,” however, is a much stronger guarantee. It means the product was tested by an accredited laboratory, and crucially, the manufacturing processes and production facility are regularly audited by third-party Certification Bodies to ensure every product consistently meets the standard. Always look for certification.
Demystifying PAS24: Common Questions and Misconceptions
The technical nature of security standards can lead to confusion. Clarifying some common questions helps empower consumers to make informed choices.
Is PAS24 a Legal Requirement for All Windows and Doors?
No. As mentioned, PAS 24 is a legal requirement only for new-build dwellings in England under Approved Document Q. It is not a legal requirement for replacement windows or doors in existing properties, though it is highly recommended as a security upgrade.
PAS24 vs. Secured by Design (SBD): Understanding the Relationship
Secured by Design (SBD) is a police initiative that aims to improve the security of buildings and their surroundings to create safer places to live. SBD is not a standard itself but an accreditation scheme. For windows and doors to achieve SBD accreditation, they must first be certified to PAS 24. SBD often includes additional requirements, such as mandating specific types of glass or hardware, making it a higher-tier specification built upon the foundation of PAS 24.
Does PAS24 Apply to All Materials? (e.g., UPVC, Timber, Aluminum)
Yes. The PAS 24 standard is material-neutral. It specifies the performance a product must achieve, not what it must be made from. As a result, you can find PAS 24 certified windows and doors made from UPVC, timber, aluminium, and composite materials. The key is how the complete system—frame, hardware, and glazing—performs under testing.
Understanding PAS24 Versions: From PAS24:2016 to PAS24:2022+A1:2024
The British Standards Institute periodically updates PAS 24 to counter evolving security threats. The number after the colon indicates the year of publication (e.g., PAS 24:2016). Recent updates like PAS 24:2022 and its 2024 amendment introduce more stringent test methods, reflecting new intelligence on criminal tactics. When specifying products, opting for the latest version ensures the highest level of security.
PAS24 vs. European Standards (e.g., RC2): Which Standard is Relevant in the UK?
While European standards for security, such as EN 1627 (which includes resistance classes like RC2), exist, PAS 24 is the established and most relevant benchmark for domestic dwellings in the UK. It is specifically referenced in UK building regulations and is the standard recognised by UK police and insurance companies.

Knowing what to look for and how to verify it is key to ensuring you get the protection you’re paying for.
What to Look For: Key Features and Strength Characteristics of PAS24 Doors and Windows
PAS 24 certified products typically feature multi-point locking systems, stronger frames, and laminated or toughened glass. For doors, which are a primary entry point in 34% of burglaries according to Reolink, look for anti-snap, anti-drill, and anti-bump lock cylinders, as well as robust hinges and a solid core. For windows, features like internal glazing beads (which prevent glass removal from the outside) and high-security hardware are essential strength characteristics.
Verifying Authenticity: How to Check for Genuine PAS24 Certification
The most reliable way to verify a claim is to ask for the certification document. This certificate for doorsets or windows will be issued by a reputable UKAS-accredited Certification Body and will detail the product range it covers. Reputable manufacturers and installers, a professional company you can trust, will readily provide this documentation. You can often find a majority of companies listed in directories from certification bodies, which can be useful when using a search filter to find suppliers.
In a world where home security is paramount, PAS 24 provides a clear, reliable, and independently verified benchmark for the performance of windows and doors. It moves beyond superficial features to guarantee a product has withstood rigorous tests designed to simulate real-world attack scenarios from an opportunistic burglar. By meeting this minimum standard for enhanced security, PAS 24 certified products offer a fundamental layer of protection that is essential for modern homes.
When planning your next project—whether a new build requiring compliance with Approved Document Q or a renovation aimed at improving safety—prioritising PAS 24 is a direct investment in your security and peace of mind. Always ask for proof of third-party certification from accredited Certification Bodies to ensure the products you choose will deliver on their promise.
