Product approval & certification

BBA certification is recognised throughout the construction industry as a symbol of quality and reassurance. It's the vital ingredient in the provision of assurance, quality and integrity to a plethora of stakeholders in the construction industry.


For the majority of people, windows and doors are arguably the most regularly encountered features of everyday life, yet we hardly notice them. However, the safety of fenestration products should never be taken for granted. This is why the BBA provides numerous Certificates to protect this sector.


Since our establishment in 1966, we have proudly worked with some of the largest fenestration product manufacturers to assess and approve a variety of innovative products. BBA Certification means that your brand will be recognised as having been rigorously tested to meet all UK Building Regulations.

For fabricators in the windows and doors sector, the good news is the BBA can make the road to Certification and approval even easier. We operate a fabricator-friendly scheme in which we combine assessments and test reports from System Suppliers, often without the need for any further testing. Sometimes fabricators can benefit from a full BBA Certificate with just a factory production control visit.

This means architects and specifiers can choose products like windows, door sets, and associated hardware etc in the knowledge that they have been properly assured by the BBA to meet industry standards. So that ultimately, homeowners and tenants end up with windows and doors that are fit-for-purpose and meet Secured By Design.

Secured by Design

Working with the Metropolitan Police, the Secured By Design scheme allowsSecured by Design in conjunction with the UK Police you to register your windows and doors with Secured by Design – a leading security approval scheme run by the UK Police to show that products are secure and can meet Approved Document Part Q (security).

Fabricators holding BBA accreditation can apply for Secured by Design registration using their BBA certificate, provided the system has an Enhanced Security Product Sheet (ES sheet) included within the scope of the certificate.

In addition, BBA opens doors to more business opportunities in the New Build Market and at NHBC sites.

As well as fenestration, the BBA provides expert certification and assessments for a wide range of products, from building insulation systems, engineering products and road surfacing materials to paints, sealants, adhesives and many more.

Getting started

Needless to say, expert technical assessments and certification can be a reasonably lengthy process as the emphasis is on technical excellence. However, the BBA is focused on working with our clients to make sure they can get their product to market with a BBA certification in the shortest possible time. To get your product certified by the BBA we begin by testing various aspects of the window and door including:

Testing door

Weathertightness, operation and strength, repeated opening and closing, basic security, thermal transmittance, enhanced security, resistance to soft body and heavy body impact plus resistance to corrosion of window/door hardware.

We also carry out various durability tests depending on the material type of the window and door. For PVC-U we would look at softening temperature, resistance to impact at low temperature, tensile strength and elongation, tensile impact and dehydrochlorination.

For timber products, we would look at wood preservation, moisture content, water absorption, adhesion of coatings, impact resistance of coatings. For aluminium products, we would look at adhesion of coatings, resistance to impact, abrasion and scrubbability.

For all systems, we would also carry out resistance to UV ageing to measure colour change over time. This ageing can be either with our extensive range of QUV machines using UVB313, UVA340 or UVA351 lamps or Xenon ageing using our Xenotest machine.

For fabricator Certificates where we have already assessed a window/door system, we would simply carry out a factory visit in order to measure production control, plus an audit test for security to ensure the window/door still meets the requirements of PAS24 (security).

The BBA certifies products that satisfy or contribute to satisfying the relevant national Building Regulations.

Bespoke certification services

PAS 24

As well as Agrément Certification, we also offer Certificates of Conformity to national standards, including PAS24 (enhanced security), and this Certification can be used to achieve registration with Secured by Design.

Certificates of Conformity involve an annual factory visit to ensure the product is still being manufactured in the same way, with the same raw materials and to the same specification.

An annual security audit test is also carried out. This involves testing a window or door with particular loads and hand tools to simulate an intruder breaking in, making sure the product still meets the requirements of the PAS24 standard.

BFRC Energy Rating Certificates

The BBA also provides an independent window and door energy rating certification scheme for the BFRC (British Fenestration Ratings Council).
