NOTE: The daily rate is shown as £1, but the minimum rental period is 30 days, as that is the minimum time to get a good set of readings. Rental, for a period of less than 30 days, will not be accepted. Local councils in the UK require or strongly advise radon gas readings, particularly for landlords, employers, and new-build developers in designated "radon affected areas". While not generally mandatory for private homeowners, testing is highly recommended, and local authorities have enforcement powers if high levels are found in rental properties. Landlords, under the Housing Act 2004 and Duty of Care, must ensure a safe home. If a rental property is in a high-risk area, the local authority may require testing and, if levels exceed 200 Bq​/​m³, they can enforce remedial action. The AEGTEST HOUND-3786 Home Radon Monitor is a reliable and easy-to-use device for keeping track of indoor radon levels. It delivers fast initial readings with regular 10-minute updates, while long-term logging and on-screen charts make trends easy to understand without needing an app or lab testing. The clear 3.5-inch colour display, rechargeable battery, and helpful sound and light alarms add to its everyday practicality. Overall, it’s a solid choice for people who want straightforward, accurate radon monitoring and clear reporting in a compact unit.
