If your home is damp, cold or falling apart, there’s a good chance it’s affecting your health. Millions of people across the UK live in homes that don’t meet basic standards, and the consequences go well beyond peeling wallpaper. Let’s see what poor housing actually does to your body and mind, and what you can do about it.
Cold Homes and the Strain on Your Body
A home that can’t hold heat will do more than make you uncomfortable. Prolonged exposure to cold indoor temperatures puts real pressure on your cardiovascular system. Your blood vessels constrict to conserve warmth, which raises blood pressure and increases the risk of heart attacks and strokes, especially in older adults.
The NHS spends an estimated £1.4 billion every year treating illnesses linked to cold and damp homes, according to the House of Commons Library. That figure covers everything from GP visits and A&E admissions to long hospital stays. Most of these are preventable if homes are properly insulated and heated.
Cold bedrooms are a particular problem for young children and the elderly. The NHS and the Lullaby Trust recommend keeping a baby’s room between 16-20°C, as temperatures outside that range increase the risk of SIDS, while colder, damper rooms create conditions where mould and respiratory infections are more likely to take hold. For older people with existing heart or lung conditions, poorly heated homes during winter will make symptoms noticeably worse and can lead to more frequent GP visits and hospital admissions.
Damp and Mould: More Than a Cosmetic Problem
Black mould on walls and ceilings isn’t just unsightly. It releases spores into the air that you’ll breathe in every day. For people with asthma, this can trigger frequent attacks and make the condition harder to control. For those without asthma, prolonged mould exposure can cause it to develop in the first place.
Children are especially vulnerable. An estimated 3.6 million children in England live in poor-quality housing, and many of them are exposed to damp and mould on a daily basis. Persistent coughs, wheezing, and chest infections are common in kids living in these conditions. Some will go on to develop chronic respiratory problems that follow them into adulthood.
It’s not only your lungs that take the hit. Damp environments encourage dust mites and bacteria to thrive, which can cause skin irritation, allergic reactions and eye infections. If you’ve noticed your symptoms are always worse at home, the building itself could be the cause.
How Your Home Affects Your Mental Health
The physical symptoms get most of the attention, but the mental health impact of poor housing is just as serious. Living in a home with visible mould, broken fixtures, and constant cold creates a background level of stress that’s hard to escape.
Research from Shelter has shown that people in poor housing are more likely to experience anxiety and depression. Children living in overcrowded or substandard homes often struggle at school, find it harder to concentrate, and feel embarrassed about inviting friends over.
There’s also the frustration of dealing with unresponsive landlords. Reporting problems repeatedly and getting nowhere will wear anyone down over time. That sense of helplessness can make existing mental health conditions worse and create new ones. But tenants now have more legal protection than they did a few years ago.
What the Law Now Says About Repair Timescales
Tenants in social housing now have stronger legal protections than they did a few years ago. Following the tragic death of two-year-old Awaab Ishak in December 2020, which a coroner later ruled was directly caused by prolonged mould exposure in his family’s housing association flat in Rochdale, the government eventually introduced new rules.
Awaab’s Law came into force in October 2025, setting legally binding repair timescales for social landlords for the first time. Now they must investigate hazards like damp and mould within set timescales, and begin repair work promptly.
These fixed repair timescales mean landlords can’t simply log a complaint and leave it for months. If they fail to act, tenants have grounds to escalate the issue. For anyone dealing with damp and mould in social housing, it’s also possible to claim compensation if the disrepair has caused health problems or damaged personal belongings. Specialist solicitors can assess your situation and advise on whether you have a valid claim.
If you rent privately, the Homes (Fitness for Human Habitation) Act 2018 gives you the right to take your landlord to court if your home is unfit to live in. This covers issues like serious damp, faulty heating, and structural defects. Your landlord has a legal obligation to keep the property in a reasonable state of repair, and you don’t need to wait for them to act on their own.
Make sure you document everything. Photograph the damp, save copies of emails and letters, and keep a record of any health appointments linked to your housing conditions. This evidence will be important if you ever need to take formal action.
A Problem That Won’t Fix Itself
Poor housing conditions don’t improve on their own, and neither do the health problems they cause. If your home is making you or your family unwell, don’t wait for your landlord to get around to it. Know your rights, keep records, and get advice. The longer you leave it, the harder it will be to undo the damage to both your home and your health.
