Stress-free Deliveries – Leave no gaps


We work closely with our customers and understand the frustrations of installation delays due to unreliable deliveries.  That’s why we pride ourselves on our ability to get stock to site – on time and in full!

Last minute time slots on site aren’t a problem with our reliable, next day delivery service across the UK.

Plus since we own our own fleet of vans, FSS can even offer flexible and fast, same day delivery within London, or collections from our warehouse in Grays, Essex.




Stock Availability – Leave no gaps


Our warehouse in Grays, Essex holds stock of the entire FSi passive fire protection and cavity barrier range*, meaning we consistently have stock available…even for those last minute orders.
