Why Choose a FIRAS-Certified Contractor?

FIRAS certification is the UK's leading third-party accreditation scheme for passive fire protection contractors. Certified companies are independently audited by Warringtonfire and subject to random site inspections to ensure ongoing compliance. Building owners and insurers increasingly require FIRAS certification as evidence that fire protection work meets the required standard under the Building Safety Act.
