Improvements include better thermal insulation, double glazing, improved ventilation, new heating, and renovated kitchens and bathrooms. These upgrades extend the life of each home by decades and help tenants stay in their communities.

The retrofit programme brings homes close to new-build standards through major internal and external work, including roof and painting upgrades. It focuses on improving comfort, modernising layouts, and future-proofing houses, while offering a more sustainable and cost-effective alternative to building new homes.
