Common Questions

Q: How long does the fire retardant treatment process take?

A: Treatment time varies based on factors like curtain size and quantity, but it averages a few hours to a full day. If we treat your curtains off-site, expect a week's turnaround. We prioritize efficiency to minimise disruptions.

Q: Can I use fire retardant treatment on other fabric items in addition to curtains?

A: Yes, treatments can be applied to upholstery, bedding, carpets, rugs, and other textiles. Effectiveness depends on fabric type, so consult professionals for suitability. Our team can guide you on the best approach for your needs.

Q: How do I know if my curtains are flame retardant?

A: Check for a label on the curtains showing the fire standard, or refer to a certificate or documentation you received confirming their fire retardancy.

Q: What if my curtains don't have a label or documentation?

A: If you don't have a label or documentation for your curtains, you should consider having them treated with a fire retardant spray and obtaining a BS 5867 Part 2 Type B certificate to ensure compliance and maintain proper records.

Do Curtains Need to be Fire Retardant?

  • Domestic curtains: UK law does not require domestic curtains to be flame resistant.

  • Contract curtains: Curtains to be used in public areas and commercial buildings must meet the flame retardant requirements specified in BS 5867 Part 2 Type B or C.

How effective is our fire retardant treatment?

Our fire retardant treatments effectively prevent the spread of fire. We use only the best products on the market, and we test different materials to ensure the highest standards of quality. 

  • Video demonstration: By watching our videos you can see the effectiveness of our fire retardant treatment. To ensure consistency, the same fabric was used in both tests.


  • Comparison: Once ignition source is removed, the untreated fabric continues to burn, and drips flaming debris. In contrast, the treated fabric is extinguished immediately and no melting debris falls.

  • Certification and Testing: To learn more about the flame retarding certificates we offer and the testing processes of UKAS accredited testing houses, click the link provided.

Aftercare and Safety

  • Dry cleaning: You can dry clean treated curtains up to five times before re-treatment becomes necessary. Washing or soaking the curtains will require re-treatment.


  • Re-treatment frequency: We recommend re-treating curtains every 5 years for optimal protection.

  • Safety of our products: We use non-hazardous products that do not contain polybrominated diphenyl, a substance linked to adverse effects.


  • Room reusability: The treatment room can be reused within minutes, provided the curtains are not disturbed.

  • Additional documents: Insurance policy documents, method statements, and risk assessments can be provided upon request.


Our company uses fireproofing products that have been thoroughly tested and approved by UKAS-accredited testing laboratories and their European counterparts for various types of materials, including curtains. This comprehensive testing enables us to issue certificates of treatment, demonstrating compliance with fire safety regulations.

Customers can be assured that there is no need for further testing of our fire retardant application services on curtains, as our certificates are sufficient to comply with fire safety regulations. Our company is committed to ensuring the correct application of our products on curtains, consistently meeting high standards and adhering to all legally required fire safety regulations.
