From the website Martin Lewis money saving expert: Lack of heat is dangerous for older people and sometimes affects our mental health

all about how to keep warm if you’re at the point of cutting back on heating. But before you do, there are a few important things to consider:

• It may be dangerous for older people, or those with asthma and other health conditions. If in doubt, consult your GP and follow their advice. Age UK told us it’s important older people do all they can to stay as warm as possible.
• Will it impact your mental health? Some say a cold home affects their mental health and motivation.
  
• Rent your home? Check what your contract says about heating. Some landlords stipulate you must turn the heating on regularly, or keep the home at a minimum temperature
