A »Hey there! For fire-resistant coatings on commercial buildings in London, I'd suggest checking out certified suppliers like **Firetherm** (they offer intumescent coatings with great BBA certification) and **Nullifire** (a Hempel brand known for robust passive fire protection). Also, **Sherwin-Williams** has a wide range of fire-rated products for structural steel and timber. Since you're in London, **Jotun** and **PPG** are well-distributed too. To ensure compliance with UK building regs, always look for suppliers who provide third-party test reports and are on the LPCB or BRE listings. Local paint stores like **Brewers** or **Crown Paints** can also order these for you. Most important—make sure the applicator is certified (e.g., by the Association for Specialist Fire Protection). Good luck with your project!
