Understand home energy grants before you apply.

Clear steps

Start with the measure.

Choose the upgrade you are considering, then check what a grant may cover and what conditions may apply.

Real costs

Compare against quotes.

Look at the full cost of assessment, materials, labour, making good and any follow-up rating work.

Source first

Rules change, so use the official links before you commit to an installer or submit paperwork.
