The final of the five standards is draught stopping. This relates to ensuring the property doesn’t have unreasonable gaps or holes in walls, ceilings, windows, skylights, floors, and doors which cause noticeable draughts. It also means all unused open fireplaces must be closed off or their chimneys must be blocked to prevent draughts.
Why is draught stopping important?
Draughts bring cool air in, and any gap in a home can let hot air out. This makes it more expensive to heat a home and can make the home colder than it needs to be.
Fixing any gaps and stopping draughts is an easy way to reduce heating bills, and keep your home warm and dry. Landlords can’t use the age and condition of the house as a reason not to stop gaps or holes, and any unreasonable gaps or holes in walls, ceilings, windows, skylights, floors, and doors must be fixed.
All private rentals must comply within 90 days of any new or renewed tenancy after 1 July 2021, with all private rentals complying by 1 July 2024.
