As of 13 August 2026, AI can only partly check for carbon monoxide risks at home.

What to actually do

1. Hand it to a person

   The route this page recommends

   Someone with a licence or accountable authority has to sign this before it counts.

2. Use a tool built for this

   Second choice

3. Do it yourself

   The distant third

   A chat interface, chat-fluent skill, and roughly 30 minutes until you can act on the result.

   How to actually do it

   1. Open the GOV.UK guidance on gas safety and the NHS carbon monoxide guidance, then keep both pages available for comparison.
   2. Walk through the property without removing covers or touching appliance controls, and write down every gas, oil, solid-fuel or other fuel-burning appliance and its room.
   3. Record the visible locations of vents, air bricks, chimneys, flues and carbon monoxide alarms, noting any obstruction, damage, alarm warning or failed test.
   4. Paste those observations into the prompt, include any recent work or unusual symptoms, and ask the chatbot to separate observations from matters requiring professional inspection.
   5. Compare each safety instruction and emergency action in the response with the GOV.UK and NHS pages, deleting any unsupported claim or instruction to dismantle, repair or test an appliance yourself.
   6. If an alarm sounds or you suspect carbon monoxide, leave the property and follow the emergency guidance on GOV.UK; for urgent or worrying symptoms contact NHS 111, and arrange a qualified professional inspection before treating the home as safe.

   Prompt

   I am in the UK and want to identify possible carbon monoxide risks in my home, not prove that the home is safe. Based only on the information below, produce: 1. a plain checklist of possible risk factors involving fuel-burning appliances, ventilation, flues and carbon monoxide alarms; 2. the observations I can make without removing covers, dismantling anything or testing an appliance; 3. the points that require a qualified gas engineer or other suitable professional; 4. the immediate actions if a carbon monoxide alarm is sounding, I suspect carbon monoxide, or anyone has worrying symptoms; and 5. a short list of questions to ask the professional. Do not diagnose anyone, do not say that an appliance or property is safe, and do not suggest DIY repairs or tests. Separate what I can observe from what only a professional can verify. Use current UK guidance and link to the relevant GOV.UK or NHS pages where possible. If symptoms are urgent or worrying, direct me to NHS 111, and state when an emergency response is needed.
