We confirm — within one UK business day
A real reply from the team. We hold a calibrated unit in your name and answer any pre-purchase questions.
You confirm dispatch + payment
When your unit is ready, we send the dispatch date, calibration certificate and the payment link. Cancel free up to that point.
It ships — free across UK & EU
48-hour tracked dispatch. 30-day returns from receipt. 2-year warranty. The dashboard is ready when the device arrives.
Quick answers. No small print.
Is reservation binding?
No. We hold a unit in your name and confirm everything by email before any charge. You can cancel any time before dispatch with no penalty.
When will it ship?
We are finalising calibration tooling. Reservations dispatch in shipping order — early reservations go first. We always confirm the exact dispatch date before requesting payment.
Do I pay now?
No. We only request payment once your unit is calibrated and ready to dispatch. Reservation just secures your place in the queue.
Is there a subscription?
Not for personal households. The £229 hardware price includes the app, alerts, firmware updates, local integrations and a 3-year rolling history for the life of the device. Organisations pay Envora Fleet per managed device, starting at £3/device/mo (£15/mo minimum) and scaling up through Fleet Team, Fleet Estate and Enterprise.
How is it different from a 90-day cassette?
A passive cassette gives you one number averaged over a season. Envora Radon shows the curve — minute-by-minute readings, room-by-room timelines, push alerts past WHO and UKHSA thresholds.
Where do you ship?
Free shipping across the UK and EU. For US, AU and elsewhere, drop a note in the form and we will quote shipping individually.
Pair Envora Radon with Envora One.
Two bundles that include Envora Radon plus the eleven-channel Envora One — single shipment, single payment, up to £49 off list.
Run radon and the eleven-channel monitor side by side.
Both publish to the same Envora dashboard, MQTT topic and REST API — one timeline per room, one alert routing for everything in the air.
