Improving sustainability of existing homes

Make your home more sustainable, healthy and energy efficient by improving heating, ventilation, curtains, and water use.

The first step with addressing cold, damp, inefficient homes is to identify the main problem areas and find options to improve them. Although some of these are improvements for a homeowner, many can be done by renters too.

If you are a renter with concerns about your rental, we'd encourage you to raise the issues with your landlord.
