Questions about large HMO conversions (7+ sharers) in Wrexham
Do you handle building control?
Yes. The building work in a large HMO conversion (partitions, fire separation, drainage, electrics) needs to meet the building regulations, and the conversion can also count as a material change of use. We confirm the route with building control, coordinate inspections and give you the completion paperwork.
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.
