A room thermometer makes a cold-home conversation more concrete. Use it to understand the rooms you occupy and to seek support where needed, rather than treating a single reading as a medical assessment.

Measure where people spend time

Follow the thermometer's instructions and place it somewhere representative, away from a radiator or other obvious heat source. Check the living area and bedroom at relevant times. Note whether a room is cold when someone is sitting still, getting up or going to bed, since those routines may need different heating arrangements.

  • Choose an easy-to-read display.
  • Record a few readings rather than one isolated number.

Understand the guidance

UKHSA advises trying to heat frequently used rooms to at least 18C, with comfort and individual needs considered. Some people need particular care because of age, illness or limited mobility. Ask a healthcare professional about individual concerns rather than using a website to decide that an uncomfortable or unwell person is fine.

  • Follow the person's existing care advice.
  • Include bedrooms in the discussion.

Turn information into action

Check normal heating settings, report faults and ask about energy or housing support if costs or building condition make adequate warmth difficult. Layers and draught reduction can help, but do not seal essential vents. If the home cannot provide safe warmth, arrange an appropriate alternative and seek help early.

  • Keep readings with a repair report if useful.
  • Do not delay urgent healthcare to gather more data.
