Fire Safety & Insulation Upgrades in London
Home » Retrofitting »
Safety and efficiency go hand in hand.
At Bigness Group, we provide professional fire safety and insulation upgrades that protect lives, property, and performance.
Our specialists ensure your building meets current fire-resistance and thermal-efficiency standards — reducing risks while improving comfort and sustainability.
Whether it’s a residential block, commercial space, or heritage retrofit, we deliver solutions that strengthen your building’s protection from inside out.
Why Fire Safety and Insulation Matter
Every structure must balance energy performance with safety.
Insulation saves heat, but if installed incorrectly, it can compromise fire resistance or ventilation.
Bigness Group ensures both systems work together — using certified materials, proper detailing, and full compliance with Building Regulations Parts B (Fire Safety) and L (Energy Efficiency).
We help landlords, developers, and homeowners upgrade responsibly, preventing hazards and avoiding costly remediation later.

Frequently Asked Questions
Q: What buildings require fire-safety upgrades?
Any property with outdated cladding, insulation, or compartmentation should be reviewed for compliance — especially multi-storey and mixed-use buildings.
Q: Do your materials meet UK fire-rating standards?
Yes. All materials are tested to BS EN standards and approved for their specific applications.
Q: Can you combine insulation and fire upgrades in one project?
Absolutely. We design integrated systems that deliver both safety and energy efficiency.
Q: Do you provide certification?
Yes — every project includes full test certificates, warranties, and photographic evidence for Building Control sign-off.
Q: How long does the process take?
Smaller upgrades may take a few days; larger remediation projects are scheduled in phases to minimise disruption.
