Not hope.
Proof.
Safety isn't something you trust.
It's something you see.
Haven is for
Trusted by fire service & Gas Safe professionals in their own homes
One per floor, one near the boiler, one in the kitchen. For most homes, that's 4.
If you don't feel safer the moment you see those numbers, send it back. No questions. Full refund. For life.
Take your time. Haven will be here when you're ready. But so will the green light.
"I had Nest Protect in every room. £200+ per unit. Haven showed 29 PPM in my son's bedroom. The Nest was silent. Four children in the house. We replaced every single one."
"I install boilers for a living. I see failures every week. This is the only detector in my own house."
"After 15 years on the job, I replaced every detector my family sleeps under. The display changed everything."
"My mother is 74 and lives alone. I bought her a 4-pack. I check her readings every Sunday when I call."
Tomorrow morning, you'll walk past the hallway on your way to the kitchen.
You'll glance at the screen. Zero.
You won't stop. You won't think about it. You'll just start your day — knowing that every breath your family takes is clean.
Day one, you'll check it constantly. By the end of the week, it's just part of the hallway. By the end of the month, you won't remember life before it.
That's the difference between hoping you're safe and knowing you are.
You know what that green light means now.
Tonight, your family sleeps under your roof.
Tomorrow morning, you either see a green light — or a number.
Plug in. See your number. Know.
Plug into any socket
No tools. No electrician. No wiring. Plug it in and it's on. One near the boiler, one per floor, one in the kitchen.
See your number instantly
The display lights up with real-time CO and gas readings. You'll see your first number the moment it powers on. Zero means zero.
Know your air is safe
If CO reaches 10 PPM — five times earlier than standard detectors — Haven alarms. Loud enough to wake the house. Early enough to act.

"My husband said our old detectors were 'fine.' Then I showed him the numbers. We ordered Haven that night. He doesn't argue about safety anymore."
"I had Nest Protect in every room. £200+ per unit. Haven showed 29 PPM in my son's bedroom. The Nest was silent. Four children in the house. We replaced every single one."
"I'm 74 and I secured my entire home in under an hour. No ladder. No electrician. Just plugged them in. My daughter sleeps better now — and so do I."
"Six years with a 'working' detector. Green light on. Haven showed 47 PPM in our son's bedroom the first night. The old detector? Still green. Still silent."
"I bought a set for our house and sent one to my parents. Mum is 76 and lives alone. Her old detector was 12 years old. Now I don't lie awake at 2 AM wondering if she's okay."
