Under Certificate Number 4780, Lochlie holds dual certification, establishing a recognised standard of fire safety compliance across the UK.

Achieving Q-Mark certification follows specialist training, rigorous process auditing, and independent assessment. Correct installation and maintenance are critical to life safety - even a fully tested fire doorset can be compromised if frames, fixings, seals, and ironmongery do not strictly match technical compliance standards.

BM TRADA Q-Mark certification provides clients with independent third-party assurance that all installation and maintenance work is completed through controlled, documented, and fully traceable processes. Holding certified status across both installation and maintenance ensures total accountability across every stage of a doorset’s lifecycle.

A spokesperson for Lochlie Construciton Group said: “Every fire door we install or maintain is delivered to BM TRADA Q-Mark standards (STD052 and STD058) by our own skilled trades team, so you get consistent quality and full accountability on site.

“Each door set within our certified scope comes with a complete audit trail, component verification, and official certification records. From commercial and public projects to third-sector and residential developments, we bring that same assurance to clients across West Central Scotland.”
