Who we are
A specialist subcontractor built on fire safety.
NQB Passive Fire Protection is a forward-thinking, dynamic subcontractor with a wealth of experience in the passive fire protection sector, covering both fire doors and fire compartmentation. We've quickly built a reputation for providing efficient, cost-effective and safe solutions across a wide range of projects.
As specialists delivering the full scope of passive fire protection, we've worked with all the leading fire protection manufacturers — giving us comprehensive knowledge of every product and system — and offer an efficient and exemplary supply and installation service.
Expertise.
Comprehensive knowledge of every leading manufacturer's products and systems — specified correctly and installed correctly, first time.
Compliance.
Safe, compliant solutions delivered to a wide range of residential, commercial and public sector projects.
Protection.
The full scope of passive fire protection, supplied and installed by one accountable, dedicated team.
How we work
Survey. Specify. Install. Evidence.
One accountable team from first site visit to handover documentation — engaging us early reduces the risk of specification conflict and abortive works later in the programme.
Survey
We inspect the building — risers, ceiling voids, lofts, service penetrations — and record the actual condition of compartmentation, not assumptions.
Specify
The right tested system for each detail, drawn from every leading manufacturer's range, matched to the building's fire strategy.
Install
Supply and installation by directly managed teams — including occupied buildings, with exclusion zones, making good and minimal disruption to residents.
Evidence
Works recorded and documented at handover, supporting the golden thread of building safety information your duty holders now rely on.

Built for the new era of building safety.
The Fire Safety Act 2021 and Building Safety Act 2022 have changed what clients, principal contractors and duty holders must be able to prove about their buildings. Compartmentation is no longer a box to tick — it's a liability to evidence.
We install tested, certificated systems to the manufacturer's specification and document what we've done, where and with what — so the information duty holders need is there when they need it.
Good fire stopping is good building physics, too: sealed penetrations and closed cavities improve airtightness and energy performance, and systems that last the life of the building avoid the waste and embodied carbon of replacement — fire safety and net zero pulling in the same direction.
Tested systems only
Systems installed to the tested detail and manufacturer's specification — never improvised on site.
Golden thread ready
Installations recorded and evidenced at handover, supporting the building's safety information record.
Early engagement
Bring us in at design or pre-construction stage to avoid specification conflict and abortive works.
Fire safety × net zero
Durable, correctly sealed compartmentation that also improves airtightness and cuts lifetime material waste.
Track record
Example of works completed.
Recent packages delivered across occupied residential blocks — surveyed, sealed and made good with minimal disruption to residents.
Penetration sealing & riser compartmentation across six blocks
- Ceilings removed in the protected lobby, kitchen, bathroom and bedrooms within flats to complete penetration sealing — then reinstated and made good.
- Compartmentation completed within risers.
- Acoustic ceilings removed within communal areas, penetration sealing completed and made good.
Soffit replacement to achieve Class 0 spread of flame
- Existing PVC soffit board removed and replaced with 12 mm Magply to achieve Class 0 spread of flame.
- Works completed from MEWPs with exclusion zones in place throughout.
Loft compartmentation with Firefly cavity barriers
- No compartmentation was found in the loft spaces on survey.
- Firefly batt walls installed into the loft spaces as cavity barriers, continuing the compartment walls to the underside of the roof.
- Firefly Cavity Closure used at the head to close the void between the roof membrane and roof tiles.
Common questions
Frequently asked questions.
What is passive fire protection?
Passive fire protection is built into the fabric of a building to contain fire and smoke — measures like fire barriers, penetration seals, fire rated ductwork, intumescent coatings and fire doors. Together they compartmentalise the building, slowing fire spread and protecting escape routes. NQB delivers the full scope, covering both fire doors and fire compartmentation.
What services does NQB provide?
Five core services: fire barriers (Stonewall, Firefly and Rockwool), fire penetration seals, fire rated ductwork, intumescent paint, and fire door installation and maintenance — all offered as a full supply and installation service.
What types of projects do you work on?
Residential, commercial and public sector projects across the UK. Key clients include Persimmon Homes, Lambeth Council, Guinness Partnership, Harlow Council and Morgan Sindall.
Do you work in occupied residential buildings?
Yes. Recent packages were delivered across occupied blocks of flats — removing and reinstating ceilings for penetration sealing, working from MEWPs with exclusion zones in place, and making good with minimal disruption to residents.
How do your works support the Building Safety Act and the golden thread?
Under the Building Safety Act 2022 and Fire Safety Act 2021, duty holders must be able to evidence the fire safety measures in their buildings. We install tested, certificated systems to the manufacturer's specification and document the works at handover — what was installed, where and with what — supporting the golden thread of building safety information.
Can passive fire protection support net zero goals?
Yes — the two pull in the same direction. Correctly sealed penetrations and closed cavities improve airtightness and energy performance, and durable tested systems that last the life of the building avoid the waste and embodied carbon of repeat replacement.
Which fire protection manufacturers do you work with?
NQB has worked with all the leading fire protection manufacturers and has comprehensive knowledge of their products and systems — including Firefly, Rockwool, Promat, Magply and Fermasteel systems referenced across our services and completed works.
