Funding and grants for retrofit
There are a number of home efficiency grants and schemes that can help you to fund upgrades to your home, helping it to stay warmer for longer. What you are eligible for can often depend on your financial circumstances and where you live.
Our retrofit grants and funding section has lots of information on the available funds, and our EcoCosi team can help sign-post you towards the correct financial support
