Shifting fire regulations

The Building Safety Act 2022, introduced in July 2021, will become law on April 1, 2023, alongside The Fire Safety Regulations 2022, which became law on January 23, 2023.

These regulations establish duties and responsibilities for the “Responsible Person” involved in construction, including landlords, managers, specifiers, and designers.

The Responsible Person must ensure that buildings are constructed using appropriate and properly assessed fire-safe materials.

Furthermore, they are required to establish a comprehensive electronic “Golden Thread” of data and information about the building, which must be stored permanently.

Failure to comply with these changes carries severe consequences, including unlimited fines and custodial sentences.

What are the current fire regulations?

The use of combustible materials in buildings exceeding 18 meters in height is now prohibited.

To assess how resistant a roofing tile is to fire spread, it undergoes rigorous testing in accordance with British Standards BS EN 13501-1.

To achieve fire-safe accreditation, a slate tile must pass up to five different tests, evaluating the following:

1. The combustibility performance of the material

2. The smoke production when the material is burned

3. The fire spread potential associated with the material

After completion of the tests, the material or product is assigned three distinct ratings:

1. Combustibility rating ranging from A1 to F.

2. Smoke production rating categorised as s1, s2, or s3.

3. Flaming particles or droplets rating identified as d0, d1, or d2.

These ratings collectively indicate the overall fire safety of the material.
