What is Regulation 7 and how can its requirements be met?


'Building a Safer Future: An Independent Review of Building Regulations and Fire Safety' by Dame Judith Hackitt contained a diagram that outlined the many ways to meet Regulation 7.  Below is an explanation of the diagram, using Automist as an example. Notably, disruptive innovation is not expected to comply with existing Standards, only demonstrate it can provide equivalent performance.


Diagram showing how to meet Regulation 7


“Is the product a standardised product?”

Is the product in question within the scope of an EN or BS standard? A screw is a standardised product for the purposes of interoperability. EN 54 detectors are also standardised.  Many products fall within the scope of a harmonised European standard, even if there is no standard specific to that product.  Electromagnetic compatibility and the Construction Products Directive for example.

All electrical devices and gas appliances are captured by a harmonised standard, as well as construction products.  If there are applicable European Standards published, products must comply with them.  This means the manufacturer must affix a CE Mark to the product (acknowledgement of a harmonised standard applies) and must be able to prove that it meets the performance requirements in these standards, and produce a declaration of conformity stating which standards apply to the product. Third-party testing by a European notified body (a laboratory recognised by the EU) is used to demonstrate this and should not be confused with third-party certification.

“Not within a harmonised standard but within a British Standard?”

If the product falls within the scope of a British Standard the product should be certified against that British standard, as third party evidence of its ability to perform. It is important to note that this only applies when a product is within the scope of a standard and therefore a test protocol exists to validate its performance. One which is out of scope may require a new test protocol to that standard by a third party laboratory.

“Not a standardised product?”

When the product does not fall within the scope of a standard, a custom third-party certification may be required. This process may take an extended period of time because the laboratory has to define the potential failure modes of the product and then create adequate tests for them. 

Regulation 7 states that either a UKAS or an equivalent accredited national laboratory can demonstrate the performance of a product for its intended purpose. 

In summary, for many products, both European harmonised standards and British Standards may apply. However, EN requires third party testing by Notified Bodies with a declaration by the manufacturer, while a BS requires third-party certification.  If a product is out of scope of either, third party testing is not mandatory, but it is desirable to demonstrate the product’s ability to perform. 

The role of third party certification

Third-party certification is an essential component of demonstrating that a product will perform as intended.  It is similar to an audit, but for a product against an established procedure and provides evidence that a product complies with a given standard. It is superior to a declaration of compliance which is drafted only by the manufacturer. 

There are many residential sprinklers for sale in the UK, which are not certified in a UKAS accredited laboratory, but instead only UL Listed: 

‘at the time of writing most sprinkler heads sold in the UK are tested and approved to a US standard, UL1666)’, see BAFSA Information File 29.

N.B. The standard referenced is incorrect, UL 1626 is the correct sprinkler standard, equivalent to UL2167 for watermist.
