OC Services designs, installs and maintains fire alarm systems for homes across Surrey. Every system is tailored to your property, installed to BS 5839-6 and backed by ongoing support from our local, DBS-checked team.
Optical and ionisation detectors for hallways, landings, living areas and bedrooms. We'll recommend the right type for each location based on the risk.
For kitchens, garages and utility rooms where smoke detectors would cause false alarms. Heat detectors respond to rapid temperature rise without being triggered by cooking or steam.
Essential for any property with gas appliances, boilers, wood burners or open fires. CO is odourless and invisible — a detector is the only way to know it's there.
Wired or wireless interconnection so that when one detector activates, every alarm in the property sounds. Critical in multi-storey homes where you might not hear a single detector from another floor.
Advanced detectors combining smoke and heat sensing for faster, more accurate detection with fewer false alarms.
Door entry systems are used constantly — so reliability matters. We offer maintenance and responsive support to keep:

Do I legally need a fire alarm in my home?
If you're a homeowner-occupier, there's no legal requirement but it's strongly recommended. If you're a landlord, the law requires at least one smoke alarm on every storey and a carbon monoxide alarm in any room with a fixed combustion appliance. HMOs have additional requirements depending on the property category.
What's the difference between BS 5839-6 Grade D and Grade A?
Grade D is the most common for standard homes — mains-powered detectors with battery backup. Grade A is a full fire alarm system with a control panel, typically required in larger HMOs or higher-risk properties. We'll advise which grade applies to your property.
