Can you work with my architect?
Yes. We often build from an architect’s drawings, or we can recommend a designer to prepare them.
What fire alarm does a large HMO need?
The fire risk assessment and the council decide; alarm grades come from guidance, not statute. For larger HMOs, council guides and the NI fire service guide commonly point to a Grade A panel system covering escape routes and rooms. We fit to the specification set, and give you the commissioning certificate.
