Frequently asked questions
Questions We Often Hear
About Our Services
Do you only install new fire alarm systems, or can you work on existing ones?
Both. We handle everything from small additions to a current system through to full replacements. We work with conventional and addressable systems of all sizes and complexity.
What areas do you cover?
We cover Essex, London, Hertfordshire, Suffolk and the surrounding counties. Get in touch and we’ll let you know if we can help.
Do you offer fire extinguisher servicing as well as installation?
We supply, install and service fire extinguishers as part of our full fire protection offering.
Compliance & Regulations
Do your installations meet current fire safety regulations?
Yes. All of our fire alarm installations comply with BS5839:1:2025 and are carried out to BAFE standards. We’re also FIA members and Safe Contractor accredited, so you can be confident the paperwork is as solid as the installation.
What happens if my building doesn’t meet fire safety requirements?
We’ll tell you honestly what needs to change and why. We don’t just make a system look good, we make sure it works perfectly, is fully compliant, and keeps everyone safe.
Do we need a risk assessment before installation?
We’ll carry out a free site survey and guide you through everything your building requires. Method statements and RAMS are provided for every project.
