The hon. Gentleman is absolutely right. My hon. Friend the Member for East Londonderry (Mr Campbell), who is sat to my left, also had constituents who passed away a few years ago due to carbon monoxide poisoning. That was in a holiday home, but it was none the less a problem. We in the APPG will take the comments of the hon. Member for Huddersfield (Mr Sheerman) on board, and we look forward to working with him.
Let me detail some of my concerns arising from the evidence that we heard. The effects of poor housing are estimated to cost the NHS £2.5 billion per annum; that rises when we consider all housing throughout the United Kingdom of Great Britain and Northern Ireland. The true cost lies in human misery and lives lost. Some of the figures are quite extreme, but they underline the issue. Some 43,900 excess winter deaths occurred in England and Wales in the winter of 2014-15, with cold homes causing one fifth of those. That is more than the number of deaths caused by road accidents, alcohol or drug abuse, which puts into perspective the need to make sure that homes are healthy. Children in cold homes are more than two times more likely to suffer from a respiratory problem. Cold homes increase the incidence of cold and flu, and worsen conditions such as arthritis and rheumatism. Again, we see that every day in our constituencies.
One in four adolescents living in a cold home is at risk of multiple mental health problems, so we are not always talking about physical issues; there can be emotional and mental issues as well. Those in poor-quality homes that lack effective ventilation suffer from indoor air pollution, which has been linked to allergies, asthma, lung cancer, chronic obstructive pulmonary disease, cardiovascular disease and, more recently, dementia.
