Introduction: The HVM Threat Landscape in the UK
Hostile Vehicle Mitigation (HVM) has become one of the most significant security disciplines in the United Kingdom over the past decade. The use of vehicles as weapons — popularised by international terrorist incidents from Nice (2016) through Berlin (2016), London Bridge (2017), and Stockholm (2017) — fundamentally changed the threat calculus for crowded places, transport hubs, government buildings, and public events across the UK.
The UK's response to this threat has been led by two government bodies: the National Counter Terrorism Security Office (NaCTSO), which provides guidance and support to the private sector and local authorities, and the Centre for the Protection of National Infrastructure (CPNI), which protects critical national infrastructure (CNI) sites including power stations, water treatment works, communications infrastructure, and government buildings.
Certified security bollards — tested and approved to national and international standards — form the cornerstone of the UK's physical HVM strategy. A single PAS 68-rated security bollard, correctly specified and installed, can stop a 7.5-tonne vehicle travelling at 30 mph dead in its tracks and protect the people behind it. Conversely, an uncertified or incorrectly installed bollard offers little more than aesthetic deterrence and may create false confidence without genuine protection.
This guide provides a comprehensive technical and commercial reference for security professionals, local authority security officers, venue managers, and procurement teams seeking to understand, specify, and procure certified security bollards in 2026.

PAS 68, IWA 14 & STS 202: Standards in Depth
PAS 68 Explained
PAS 68 — the Publicly Available Specification for Vehicle Security Barriers — was developed by the British Standards Institution (BSI) in 2007 and updated in 2013 (PAS 68:2013) in response to growing demand for a national standard for anti-vehicle barriers. The specification defines the test methodology, performance criteria, and product classification system for vehicle security barriers tested against vehicle impact.
The PAS 68 test methodology requires that barriers are subjected to full-scale vehicle crash tests conducted under controlled conditions. The test vehicle is driven at a defined speed and angle into the installed barrier system, and the performance is assessed on the basis of:
- Penetration distance (Pd): How far the test vehicle penetrates behind the barrier face after impact. Categories range from Pd0 (no penetration) to Pd10 (vehicle penetrates 10 metres). For high-security applications, Pd0 or Pd1 are specified.
- Debris dispersion: The pattern in which vehicle components, cargo, and barrier debris are distributed after impact. Particularly important for protecting people behind the barrier.
- Structural integrity: Whether the barrier system remains in a condition capable of resisting further vehicle attempts after the initial impact.
PAS 68:2013 was withdrawn by BSI in June 2019 when IWA 14 was revised to incorporate PAS 68 requirements. However, "PAS 68 tested" or "PAS 68 equivalent" remains widely used in UK commercial and government procurement as a descriptor meaning that the product has been tested to BSI-equivalent vehicle crash test standards.
IWA 14 Explained
IWA 14 (International Workshop Agreement 14, Vehicle Security Barriers) is the ISO-level international standard developed to harmonise vehicle security barrier testing across national standards from the UK (PAS 68), the USA (ASTM F2656), and Europe. It was first published in 2013 and significantly revised in 2021 as IWA 14-1:2013 and IWA 14-2:2013 (parts covering performance requirements and application respectively).
IWA 14 uses the same fundamental test methodology as PAS 68 — full-scale vehicle crash tests with defined vehicle type, mass, speed, and impact angle — but harmonises the classification notation and test conditions to enable international mutual recognition. Products certified to IWA 14 by UKAS-accredited test laboratories are acceptable for procurement by UK government bodies and CNI operators as equivalent to PAS 68-tested products.
The key advantage of IWA 14 for manufacturers and procurers is international recognition: a single certification allows products to be marketed and procured in the UK, across EU member states, in North America (where ASTM F2656 applies), and in other IWA 14 signatory countries without re-testing.
STS 202 Explained
STS 202 (Security Technical Specification 202) is a UK government security test standard developed and administered by DSTL (Defence Science and Technology Laboratory), part of the UK Ministry of Defence. STS 202 is specifically used to certify vehicle security barriers for the most critical government and CNI applications, including Ministerial properties, intelligence agency sites, military installations, and police facilities.
STS 202 differs from PAS 68/IWA 14 in several important respects:
- It uses proprietary test conditions that reflect specific government threat scenarios, which are not publicly disclosed in full detail
- Products approved under STS 202 are listed on the CPNI-approved products database, accessible to approved organisations
- The standard includes requirements for dynamic barriers (retractable/rising/automatic systems) that go beyond the scope of PAS 68/IWA 14
- STS 202 approval requires site-specific structural and geotechnical assessment as part of the certification process
STS 202 is not applicable in most commercial contexts. For the vast majority of crowded places, retail, hospitality, and local authority applications, IWA 14 / PAS 68 tested and CPNI-listed products are the appropriate specification.

The Rating System Decoded: V/7200[N3]/48/90
When procurement teams and specifiers review security bollard product data, they will encounter performance ratings expressed in the standardised PAS 68/IWA 14 notation. Understanding this notation is essential for correct product selection. Here is a complete breakdown:
Notation Structure
V/7200[N3]/48/90:Pd1
| Element | Meaning | Examples |
|---|---|---|
| V | Vehicle (indicating this is a vehicle impact test) | V (always V for vehicle barriers) |
| 7200 | Vehicle kerb mass in kg (the test vehicle's weight) | 1500 (car), 3500 (van), 7200 (7.5T rigid lorry), 30000 (artic HGV) |
| [N3] | Vehicle category per EC Directive 2007/46/EC: M1=car, N1=light van, N2=medium lorry, N3=heavy lorry |
[M1] car, [N1] van, [N2] LGV, [N3] HGV |
| 48 | Impact speed in km/h | 30, 48, 64, 80 — higher = more severe threat |
| 90 | Angle of impact in degrees (90° = perpendicular / head-on) | 90 (head-on), 45 (oblique) |
| Pd1 | Penetration distance category: Pd0=no penetration, Pd1=1m, Pd2=2m... Pd10=10m |
Pd0, Pd1 (highest security), Pd5 (moderate) |
Common UK Rating Scenarios
- V/1500[M1]/64/90:Pd0 — Car at 64 km/h, head-on, no penetration. Minimum spec for pedestrianised areas.
- V/3500[N1]/48/90:Pd1 — Van at 48 km/h, head-on, 1 m penetration. Common for town centres and shopping streets.
- V/7200[N3]/48/90:Pd0 — 7.5T lorry at 48 km/h, head-on, no penetration. Standard for crowded places and major events.
- V/30000[N3]/80/90:Pd0 — Articulated HGV at 80 km/h, no penetration. Critical infrastructure / highest threat.
The higher the vehicle mass and speed, the more demanding the certification and the more substantial the bollard and foundation must be. Specifiers should note that the rating refers to the test conditions, not the barrier's capability in all scenarios — a V/7200[N3]/48/90 bollard may or may not stop a car at 120 km/h; its rating only confirms performance at 48 km/h with a 7.2-tonne lorry.
CPNI Approved Products & NaCTSO Guidance
CPNI and the Approved Products Database
The Centre for the Protection of National Infrastructure maintains an Approved Products for Security (APS) database, accessible to registered organisations via the CPNI website. The database lists vehicle security barriers — including security bollards, rising arm barriers, and concrete protection — that have been independently tested and approved for use in CNI and government security applications. Products are listed with their performance rating notation and approved installation configurations.
For CNI operators, procurement teams should require that specified products appear on the current CPNI APS database, that the installation method matches the approved configuration, and that installation is carried out by an organisation with documented CNI security experience. Products not on the CPNI database are not necessarily inferior, but they have not been independently verified by DSTL and do not carry the same level of assurance for the most critical applications.
NaCTSO Guidance for Crowded Places
NaCTSO (National Counter Terrorism Security Office) is the national advisory service supporting businesses and organisations in protecting against terrorism. The NaCTSO CT Security team provides free, confidential advice to operators of crowded places — including stadiums, shopping centres, transport hubs, and event venues — through Local Authority CT Security Advisors (CTSAs). CTSAs can conduct site vulnerability assessments, advise on HVM measures, and recommend appropriate barrier products and configurations.
NaCTSO guidance recommends that HVM assessments for crowded places consider:
- The threat level and specific vehicle attack scenarios relevant to the site
- The vehicle approach speeds achievable given the surrounding road network
- The mass and type of vehicle most likely to be used as a weapon (typically a van or lorry for maximum impact)
- The consequences of an attack in the specific location (crowd density, emergency egress, critical assets)
- The availability of suitable foundation conditions for the bollard type being considered
Martyn's Law & the Protect Duty
The Terrorism (Protection of Premises) Act 2025 — commonly known as Martyn's Law after Martyn Hett, who died in the 2017 Manchester Arena bombing — represents the most significant change to UK venue security law in recent decades. The Act came into force in stages from late 2025 and imposes graduated security duties on venues and events based on their capacity.
Tier 1 Venues (800+ capacity)
Tier 1 venues must develop and implement a terrorism protection plan, including consideration of physical security measures. The Act does not prescribe specific products, but the accompanying statutory guidance makes clear that venue operators should consider whether HVM measures are appropriate given the threat assessment, pedestrian access routes, and vehicle access points. Annual staff security training is also mandatory.
Tier 2 Venues (200–799 capacity)
Tier 2 venues have a lighter-touch requirement focused on procedural preparedness rather than physical security infrastructure. However, good practice — and the duty to assess reasonable foreseeable risks under HSWA — means that Tier 2 operators should still consider whether vehicle attack represents a material risk and whether any cost-proportionate physical measures are appropriate.
Implications for HVM Bollard Procurement
Martyn's Law creates a documented, auditable obligation for Tier 1 venues to consider HVM. In practice, this means that venue security managers should:
- Engage their local CTSA for a venue security assessment
- Document the HVM threat assessment and conclusions in the venue's terrorism protection plan
- If HVM bollards are recommended, procure products certified to IWA 14 / PAS 68 (or CPNI-listed for CNI sites)
- Ensure installation is carried out in accordance with the manufacturer's certified method
- Maintain installation records and inspection logs
Types of Security Bollards
Fixed Security Bollards
Fixed security bollards are permanently installed into the ground and cannot be removed without specialist equipment. They represent the most reliable HVM solution because they have no mechanical parts that could fail at a critical moment and they are inherently tamper-resistant. Fixed bollards are appropriate for locations where vehicle access is never operationally required — pedestrianised zones, emergency vehicle exclusion zones, and protected perimeters.
Fixed bollards certified to IWA 14 typically consist of a steel shaft (typically 200–300 mm diameter, 1,000–1,200 mm above ground) set into a reinforced concrete foundation pad. The foundation specification is a critical part of the certified installation — the bollard's performance is entirely dependent on the foundation dimensions, concrete grade, and soil compaction being in accordance with the manufacturer's certified installation method.
Browse our security bollards collection for certified fixed options.
Retractable Bollards
Retractable (also called rising or deployable) bollards are the HVM solution of choice for locations where operational access by authorised vehicles is required during controlled periods. They can be raised to the security position to prevent vehicle access and lowered to allow authorised access.
Three principal actuation mechanisms are available:
- Manual retractable: Raised and lowered by hand using a key mechanism. Low cost, no power required, but slow to operate and dependent on human action. Suitable for low-traffic authorised access points.
- Electro-hydraulic: Powered by an electric hydraulic pump unit. Rise/lower time typically 4–8 seconds. Can be integrated with access control systems (ANPR, proximity cards, intercoms). Requires power and periodic hydraulic fluid maintenance.
- Pneumatic: Powered by compressed air. Very fast rise/lower time (1–3 seconds). Used in high-throughput authorised access scenarios. Requires air compressor infrastructure.
Retractable bollards intended for HVM duty must be certified to IWA 14 or PAS 68 in both the raised (security) and lowered (access) positions. Beware of products marketed as "security bollards" that are not certified — many decorative rising bollards offer no meaningful vehicle resistance. View our retractable bollards range for IWA 14 certified options.
Surface-Mounted Bollards
Surface-mounted (shallow-foundation) bollards are designed for locations where conventional deep foundations are impractical — typically on bridge decks, over basements, over complex underground service networks, or in listed buildings where excavation is not permitted. They use a wide-flange base plate bolted to the surface slab or deck structure, with the structural engineer specifying the anchor bolt pattern and depth based on the structural capacity of the substrate.
The performance rating of surface-mounted bollards is typically lower than equivalent deep-foundation products because the energy transmission path is different. However, current-generation surface-mounted products can achieve V/3500[N1]/48/90 performance, which is sufficient for many town centre and event applications. Always confirm the specific performance rating from the manufacturer's test report, as published specifications can refer to specific foundation configurations that may not apply to your site.
Removable Bollards
Removable bollards can be physically removed from their ground sockets for access, then replaced. They do not have the hydraulic or mechanical actuation of retractable bollards — they are simply lifted out by hand (sometimes with a key-release mechanism to prevent unauthorised removal). Removable bollards provide access control rather than high-frequency traffic management, and they are suitable for locations where vehicle access is occasional (e.g., maintenance access, once-daily delivery windows).
For HVM duty, a removable bollard is only as secure as the locking mechanism prevents unauthorised removal. High-security removable bollards use high-tensile locking pins and anti-pick key barrels. Standard removable bollards provide a deterrent and an obstacle but are not suitable as primary HVM protection against determined attack.
Specifying HVM Bollards for Crowded Places
The specification process for HVM bollards in a crowded place environment should follow this framework:
- Threat assessment: Engage your local CTSA (NaCTSO) for a threat assessment. Identify the vehicle types and speeds that represent a credible threat in the specific location. Consider approach road geometry, speed limits, vehicle access routes, and the presence of natural obstacles.
- Vulnerability assessment: Map pedestrian densities, crowd dwell zones, emergency egress routes, and the consequences of a vehicle penetrating specific distances behind the defence line.
- Performance specification: Using the threat and vulnerability assessment, define the minimum IWA 14 rating required. Common specifications for UK crowded places are V/3500[N1]/48/90:Pd0 (van threat) or V/7200[N3]/48/90:Pd0 (lorry threat).
- Access requirements: Define which access points require no vehicle access (fixed bollards), controlled-frequency vehicle access (manual retractable), or high-frequency authorised access (electro-hydraulic retractable).
- Ground conditions survey: Commission a ground investigation report covering soil type, bearing capacity, groundwater level, and the presence of underground services. This is essential for foundation design.
- Structural engineering: Appoint a structural engineer to confirm foundation designs for the selected bollard products. Verify that foundation dimensions and concrete grades meet the manufacturer's certified installation method.
- Product selection: Select products certified to IWA 14 (or CPNI-listed for CNI sites) that meet the performance specification. Obtain current test reports directly from manufacturers.
- Contractor selection: Appoint a security contractor with documented experience of installing certified HVM products. Request evidence of previous installations and CPNI-accredited installer status where applicable.
- Installation quality assurance: Arrange independent inspection during installation to verify foundation dimensions, concrete pours, anchor bolt torques, and alignment. Obtain as-built documentation.
- Commissioning and handover: For retractable systems, commission all operational modes (raise, lower, emergency drop, manual override). Provide operations manual and maintenance schedule. Train operators.
Procurement Process
Public Sector Procurement
UK public sector bodies (local authorities, NHS Trusts, emergency services) procuring HVM bollards above £213,477 (the current OJEU threshold for public works) must follow Public Contracts Regulations 2015 procedures, typically a restricted or open tender. The procurement specification should reference IWA 14 / PAS 68 certification as a minimum technical requirement and include CPNI listing as a desirable criterion. Whole-life costing — including maintenance, power, and eventual replacement — should be factored into the evaluation.
Private Sector and Commercial Procurement
Commercial procurers should obtain a minimum of three competitive tenders from security contractors with documented HVM installation experience. Key evaluation criteria should include:
- Product IWA 14 / PAS 68 test report (current, not expired)
- Manufacturer's certified installation method documentation
- Evidence of previous comparable installations
- CPNI-listed installer accreditation (for government and CNI sites)
- Ground investigation and structural engineering proposals
- Whole-life maintenance cost schedule
- Insurance and warranty terms

Frequently Asked Questions
What is the difference between PAS 68 and IWA 14?
PAS 68 was the British Standards Institution's UK specification for vehicle security barriers; IWA 14 is the international ISO standard that superseded it. Both use full-scale vehicle crash testing with the same classification notation. PAS 68 was withdrawn in 2019; IWA 14 is the current active standard. Both are accepted by CPNI. Products described as "PAS 68 equivalent" have been tested to BSI-equivalent vehicle crash test conditions.
What does the PAS 68 rating V/7200[N3]/48/90 mean?
V = vehicle impact test; 7200 = 7.2-tonne test vehicle; [N3] = heavy lorry category; 48 = speed in km/h; 90 = perpendicular impact. This means the bollard was tested against a 7.2-tonne rigid lorry at 48 km/h, head-on, with successful containment. The Pd suffix (e.g., :Pd0) indicates penetration distance — Pd0 means no penetration behind the barrier face.
Do all public places in the UK need HVM bollards?
No. The need is determined by a threat and vulnerability assessment, guided by NaCTSO and CPNI. Martyn's Law (the Terrorism (Protection of Premises) Act 2025) creates a documented obligation for Tier 1 venues (800+ capacity) to consider physical security including HVM, but does not mandate specific products.
What is Martyn's Law (the Protect Duty)?
Martyn's Law is the Terrorism (Protection of Premises) Act 2025, requiring Tier 1 venues (800+ capacity) to have terrorism protection plans and Tier 2 venues (200–799) to implement procedural preparedness measures. It creates an auditable duty to consider HVM measures for qualifying venues.
How deep do security bollards need to be installed?
A typical IWA 14 rated fixed bollard requires a reinforced concrete foundation pad of 600–900 mm depth and 400–600 mm diameter. The exact specification is determined by structural engineers and forms part of the certified installation method. Any deviation invalidates the security rating.
What is the difference between fixed, surface-mounted and retractable security bollards?
Fixed bollards are permanently installed and offer the highest security. Surface-mounted bollards use a shallower foundation and are suitable where deep foundations are impractical (lower performance rating). Retractable bollards allow controlled authorised access while providing full security when raised — suitable for operational access points. See our retractable bollards range.
How much does PAS 68 bollard installation cost?
Fixed bollards: £600–£2,500 supply + £800–£3,000 installation per unit. Hydraulic retractable: £3,500–£8,000 supply + £2,500–£6,000 installation. Ground investigation and structural engineering add £3,500–£13,000 per project. Obtain 3 competitive tenders. Contact BarriersCo for pricing.
Are CPNI-approved bollards required for all security installations?
CPNI approval is mandatory for CNI sites (power stations, water works, government buildings). For commercial venues and crowded places, CPNI listing is strongly recommended but not legally required. The CPNI approved products database provides the highest assurance of tested performance.
What is the STS 202 standard?
STS 202 is a UK government test standard by DSTL for the most critical CNI and government applications. It uses classified test conditions beyond PAS 68/IWA 14 scope. Not applicable in commercial contexts — IWA 14 is the correct standard for commercial and crowded place HVM.
Can I install HVM bollards myself?
No. The security performance of a certified HVM bollard is entirely dependent on correct foundation installation per the manufacturer's certified method. All HVM installations must be carried out by an accredited security contractor with documented experience. DIY installation will invalidate the security rating entirely.
