Your landlord will be in touch to let you know if your home is suitable for any home upgrades, and if any, when these may happen. Be aware it may not all happen at once!
Some upgrades, like solar panels and a battery are optional and Sero will contact you to explore if this is suitable for you. However there maybe some upgrades that your landlord will determine as mandatory (like ventilation) - these will be measures that will improve the health and safety of your home for you and your family.
