Housing warmth and health and well-being in Wales survey

Published: 21 January 2022

What is the study about?

Public Health Wales NHS Trust and Bangor University are carrying out a national survey on housing warmth and health and well-being in Wales. M.E.L Research is carrying out the survey on behalf of Public Health Wales and Bangor University.

Why is this study being done?

Currently, there is little information available on the indoor temperatures being achieved by households in Wales, how people heat their homes and stay warm in winter, and the impact on people’s comfort, health and well-being. This information is important to help us understand what minimum temperatures should be recommended in Wales to keep people comfortable and safe in their homes.

Who will be involved?

Between January and March 2022, households in Wales will be contacted by M.E.L Research, and residents aged 18 years or older will be invited to take part via the telephone or online. Participants can take part in Welsh or English.

Do I have to take part?

No. The survey is completely voluntary – it is up to you whether you take part. You are free to stop the survey at any time, and you do not have to give a reason. A decision to do this will not affect your rights, any current or future health treatment, or any services you receive.


How will my answers be kept confidential?

All answers will be kept completely confidential and anonymous. As the questionnaires are anonymous and we will not be able to identify your personal answers after completion, it will not be possible to withdraw from the study once the questionnaire has been submitted. You will be asked if you would like to take part in a follow-up. People who choose to take part in future studies will have their contact details held securely, and separately to their answers to this questionnaire.

Your answers will not be shared with anyone beyond the research team, UNLESS you reveal an intention to harm yourself or somebody else, information indicating somebody may pose a serious risk of harm to you or the public, or the intention to commit an act of terrorism. We would discuss this with you before telling anybody else.

Who has reviewed the study?

This study has been reviewed by the Bangor University Healthcare and Medical Sciences Academic Ethics Committee. A research Ethics Committee is a group of independent people who review research to protect the dignity, rights, safety and well-being of participants and researchers. The study has also been reviewed by the Public Health Wales Research and Development Office.
