Answer a few quick questions and get a clear recommendation for your property.
Based on UK fire safety guidance
Built around BS 5839-6 principles, property type, location, layout and installation route.
Step 1
Who is the fire alarm system for?
This helps us understand whether the property is owner-occupied or rented, so the correct fire safety rules can be applied.
Step 2
How is the rented property occupied?
Choose the second option if your tenants are individuals or groups who rent separately or are not a single family, even if they share the kitchen or bathroom. This helps us identify shared houses, which have different fire safety rules.
Step 3
How many people live in the property in total?
Count everyone who lives there, including children.
Step 4
Which best describes the property?
Only a straightforward shared house or flat can continue without a fire risk assessment. Bedsits, self-contained units and uncertain layouts need professional confirmation.
Step 5
Where is the property located?
For properties in Northern Ireland please contact us directly.
Step 6
How many floors does the property have?
Include all habitable floors including basements, lower ground floors and converted loft spaces.
Step 7
How many main living areas does the property have?
For example living rooms, lounges and open-plan living spaces. If your kitchen and living area are open plan, count them as one living area.
Step 9
How many rooms contain fuel-burning appliances?
Any room with a gas boiler, oil boiler, wood-burning stove, solid fuel fire or gas cooker where applicable. Count each room separately. If a room contains more than one appliance, count it once. If unsure, select the higher number. If your property has fuel-burning appliances in more than 5 rooms, please contact us directly.

Please note that in this hardwired Grade D1 system, the smoke and heat alarms interlink through the wired connection, but the CO alarm operates as a standalone unit. This is fully compliant in all parts of the UK, as there is no requirement for CO alarms to be interlinked with the fire detection devices.

Small HMO guidance
Your property looks like a small HMO
Based on your answers, your property may be a House in Multiple Occupation (HMO) — a shared home rented to people who are not a single household. That changes how fire safety is handled, so we are not able to give you a standard recommendation to buy right away.
Why we cannot give a blanket recommendation
HMO fire alarm requirements are not set by a single national standard. They depend on your local authority licensing conditions, and they can vary from one council to another. Because of that, we cannot reliably tell you online exactly what your property needs.
The good news
For a smaller shared house like yours — up to four people, one or two floors, with a straightforward layout — a domestic Grade D interlinked system is often acceptable. But often is not always, so it needs confirming for your specific property.
What to do next
- Contact your local authority housing or licensing team and ask whether a Grade D interlinked system is acceptable for your property, or whether they require anything more.
- If you would prefer professional confirmation, arrange a fire risk assessment with a competent fire safety professional.
- Once you have confirmed a Grade D system is suitable, come back and we will help you choose the right kit for your property.

Assessment required
Your property needs a fire risk assessment
Based on your answers, your property appears to be a House in Multiple Occupation that needs a professional fire risk assessment to determine the right fire alarm system. Larger or more complex shared housing, bedsits, self-contained units, or buildings of three or more floors typically need a Grade A or mixed system specified by a competent professional.
