Navigating third-party certification bodies for fire safety products

10 August 2026

Customers need to understand certification bodies in order to make informed product choices.

In short:

  • There are many certification bodies used for fire safety products. These include The Loss Prevention Certification Board, or LPCB, Sociéte Générale de Surveillance, also known as SGS, the VdS Schadenverhütung GmbH or VdS and the BSI Kitemark. All of these certification bodies test and certify fire safety products.
  • Independent certification from recognised bodies helps verify that fire safety products have been rigorously assessed against relevant standards, such as BS 5839-6 which sets out recommendations for domestic fire detection and fire alarm systems. This standard is more vital than ever under the Smoke and Carbon Monoxide Alarm (England) Regulations 2015, amended in 2022, mandate that all social and private rented properties must be equipped with smoke and carbon monoxide alarms that meet British Standards.

When specifying fire detection products, professionals are faced with a range of certification marks. While these logos may look similar, they represent different certification organisations that independently assess products against recognised standards, ensuring safety, quality, and performance. Understanding what each certification body does can help specifiers make more informed purchasing decisions.

Why certification matters

Supporting compliance

Depending on the safety product at hand, certification is either mandatory or voluntary. For example, smoke alarms legally require third party certification by an approved body before they can be UKCA or CE marked, while for CO alarms marks like the BSI Kitemark are voluntary but strongly recommended. Many certification bodies, like BSI Kitemark, LPCB and VdS, also exceed the basic minimum legal requirement, providing extra assurance.

Third-party certification demonstrates independent assessment, giving specifiers, installers, and residents confidence that equipment is fit for its intended purpose.

Certification bodies do not create the product standards themselves. Instead, they independently assess products against recognised product standards, such as BS EN 14604 for smoke alarms and BS EN 50291 for carbon monoxide alarms. These certified, life-saving  products can then be specified and installed in accordance with BS 5839-6, which sets out recommendations for domestic fire detection and fire alarm systems.

Understanding the different certification bodies

SGS

SGS is a global testing, inspection and certification organisation, operating laboratories and facilities across over 2,500 laboratories and business facilities across 115 countries, supported by a team of 99,500 dedicated professionals.

SGS certification provides independent assurance from an established third party that a product meets specific standards. It is also one of the key certification bodies used by FireAngel.

BSI Kitemark

The BSI Kitemark provides over 120 years safety through rigorous independent expert testing. This process involves repeated assessments to verify performance claims and ensure long-term product reliability.

This independent certification is reflected in FireAngel’s range of safety products. Several FireAngel alarms carry BSI Kitemark certification, including FireAngel FP2620W2-R – Smart Smoke Alarm and FireAngel FA3322 – Digital Display CO Alarm.

LPCB

LPCB is an internationally recognised third-party certification body for fire and security products and services, run by BRE Global.

LPCB  is intended to help ensure fire and security products perform as specified.

VdS

VdS is an example of another widely recognised certification body. It specialises in corporate security and safety, including fire protection, security, natural hazard prevention and cyber security.

Highly regarded across Europe, VdS is an EU-notified body that provides Certificates of Constancy of Performance for products used in fixed fire protection systems.

Why FireAngel uses SGS for its new Spec+ range

FireAngel’s new Spec+ range includes five Grade D1 fire and carbon monoxide alarm range for UK housing professionals, which are SGS certified. Installed in accordance with BS 5839-6, the Spec+ range delivers LD1 Maximum Protection, which is a system installed throughout a property that places detectors in all circulation areas that form part of the escape routes, and in all rooms and areas in which a fire might start, other than toilets, bathrooms and shower rooms.

The Spec+ range complies with recognised standards for smoke, heat and carbon monoxide detection, including BS 5446-2, EN 50291-1 and BS EN 14604, depending on the product.

FireAngel chose SGS as its certification partner because of its worldwide and international reputation in testing, inspection and certification. Its independent assessment verifies product safety and performance, building confidence for specifiers, installers, and residents. Importantly, the Spec+ range is certified by SGS, a UKAS accredited certification body, providing customers with confidence that FireAngel solutions meet the rigorous safety and performance requirements expected by housing providers and contractors.

Making informed fire safety choices

Certification bodies like SGS, VdS, and the BSI Kitemark, and LPCB play a critical role in the fire safety industry. By rigorously testing and certifying products, these certification bodies provide the necessary verification that products will perform reliably.

When specifying fire safety products, the key consideration is whether the product has been independently certified to the appropriate standard and is suitable for the building, system design and fire strategy. By looking beyond the logo alone, professionals can make more informed choices that support reliable, compliant fire safety outcomes.
